Fleet is expanding (heli 3 and heli 4)

It’s beyond obsession at this point. I’m going to need a 12-step program.

Yesterday I converted some old ‘iron’ at the gun shop to one of these at the hobby shop (I don’t have a need for a piddly 9mm anyway). This is Heli #3:

Blade CX3

As I type, the batteries are charging for the Heli, and the transmitter.
Blade CX3 battery packs and DX6i transmitter charging up.

I saved $35 by buying the BNF (Bind-n-Fly) version of the kit. The Spektrum DX6i I already obtained is compatible with this (and the P-51 too as a matter of fact).

Then this morning, I received shipping confirmation of ‘Heli 4’ from the on-line retailer XHeli.com. This is my first time ordering stuff from them. What surprised me was that within 24 hours the merchandise was picked, packed and on it’s way!

Thank you for shopping at XHeli!
Your order’s shipping label is generated and is scheduled
to be shipped on 05/21/2010 via UPS.

EXCELLENT!!

New Heli and parts on the way!

I’m having it shopped to my office in Tacoma since I don’t want to have it sitting on my porch all day at work. Plus, there is ALWAYS someone there to sign for it, since we are 24×7 shop. Fast FAST shipping and great prices. We’ll see how it all works out.

This is what I’m expecting. 🙂

Exceed MadHawk 300

ESky Flight Training System

Now, I already had this one here. Which now I think I paid WAYYYYYYYY too much for:

RealFlight Basic

I’ve been practicing with it for a week now. It’s OK, and it has some cool planes in it, but the helicopter physics seem… weird. Really weird. And I completely irritated that I had to build a WINDOZE box to use the thing! Luckly I still had an old (circa 2006) Dell computer floating around, and it’s running Windoze XP (which the new software needs too.. got lucky there), but the hardware was not up to the task. Wish I’d known that when I bought it. So $100 for the software kit, then I had to toss in another $80 to get a decent DX9 compatible video card for the OLD PCI (not enhanced regular old PCI) interface, AND 1GB of memory for another $50. (poor thing only had 128MB in it.. not enough to even open the program.
So almost $250 to construct a flight simulator with a used computer!

Then.. then, I find this recommendation lurking around one of the Heli message boards. Heli-X.

It’s written in Germany AND it runs on Mac OSX!!!! So of course I downloaded it (it does not come with any controller, BUT the controller from RealFlight works PERFECTLY!). It’s also fairly pricey too at $50 Euro, and it only handles Helis BUT the physics in the trainer are SO much more realistic, at least to me.

Here is a shot of the simulator (sorry, I don’t have the controller hooked up at the moment so it’s just a shot of one model on the ground). It’s pretty good, and I’m learning that Variable Pitch, fixed throttle flying IS A LOT more intimidating that fixed pitch variable throttle!

When will this end?

Proto CX Heli Flies Again (for a moment)

After a number of pretty bad nose-in crashes (flying nose in is the most challenging), the bird was getting pretty beat up:

Proto CX crash worn

With the landing gear broken and the canopy smashed, it was looking very ragged. Not only that, but the metal rod and zip ties I had holding the landing skids together added enough weight to make it fly a little funny (balance, what balance?).

Removing the weight of the rod, well.. that was not really an option:

Broken and beaten Proto CX

Fortunately, the local hobby shop has a variety of replacement parts for these things (big shock, isn’t it?). The landing gear itself was about $8.50 to purchase. Easy enough. However, with all the plug-and-play miniaturization on these things, one thing that was not plug and play was the landing gear + battery tray. I’d have to perform some micro soldering to complete the repair.

Replacement landing gear for the Proto CX

I lit up the soldering iron and did my best. Turns out that it was a little easier than I thought it would be. Plus, I didn’t accidentally melt any of the sensitive parts, like that servo there, located perilously close to the solder points I needed to use.

Completing the repair.

With the important structural stuff fixed, the canopy was re-attached and she’s ready to fly. Good, maybe bad, but the shop did not have replacement canopy in stock. It’s OK I suppose, since I’d crashed this many times on the nose before the canopy finally shattered.

Broken gear left, repaired bird right.

Some pieces are still missing, but some clear tape and Sharpie marker returned it to serviceable condition. It’s not going to win a beauty contest, but it does fly, as you can see here!

Radio Control Problem Expands – Now flying: P-51

It was bound to happen. I’m hooked. This Radio Control stuff is just as fun, if not more fun (now that I can afford basically anything I want to fly) than it was as a kit!

While driving all over Puget Sound looking for a few things (good price on transmitter set, a good 450-class heli, some training software, parts, etc. etc) we stopped at HobbyTown near PLU. This place is more like the old-school hobby shops of my youth. Piled with all sorts of cool kits. A little bit of everything. Old display fixtures and a group of characters behind every counter. Reminded me of Houston’s Hobby in the Cambrian area of San Jose. Digressing…..

Atop a counter sat a small collection of R/C demo aircraft. The Boy gravitated straight towards the P-51 mustang there, and asked if he could see if fly. It didn’t look like they had ANY place to fly a fixed-wing model, so I was surprised when the guy picked it up and said, “Sure, let’s check it out. It’s a little windy but I think we can do it.” And that he did.

I was impressed by the 4-channel micro foamy plane’s ability to fly, and to handle the breezes. The Boy wanted to see it fly over and over again, but the batter was low in the plane and it barely made it back. LOL.

Long story short, they guy at the hobby shop made a sale because of that demo. I was $135 lighter in the pocket. Which I didn’t think was *that* bad considering that buys the plane, the transmitter, receiver and servos, battery and charger, plus it’s completely Spektrum DMS2 2.4 GHz spread-spectrum compatible (how compatible I would shortly discover, more on that later). That’s it on the right there, in case you can’t tell the difference between a heli, a can of PBR and a P-51.

Proto CX Heli and HobbyZone P-51 Parkflyer

We drove all around town, even up to Tukwilla for another hobby shop before heading home with the batteries in the P-51 charging up in the back of the car.

When we arrived home, there was still plenty of sunlight to go fly. So that’s what we did! Took the little P-51 out for it’s maiden voyage. Thankfully it’s light weight and made of foam, because it spent white some time ‘landing’ on surfaces other than it’s wheels. One crash was bad enough to snap a better connector off. This was the begining of it’s downfall, and really, mine as well, I just did not know it yet. Fortunatly the battery, even though it was broken, was still able to be attached to the plane. So I crashed it until dusk and we headed home.

I discovered that flying fixed-wing is fun too! 🙂

Radio Control Flying – Documenting my 450’s part specs

One thing you learn in the tech industry is, Document your specs!. And just don’t link to some manufactures web site and call that documenting your specs. You need to do a little better job of that. I prefer to get the specs and record them in my own documentation. If you do that, you don’t have to worry about the manufacture changing specs (but not PN#), or them deleting the specs from their websites completely (e.g. Loctite deleted the specs on the 224 purple thread locker… yet I can still buy it all over town).

So, for my own edification really, I’m going to list the parts specs, original configuration vs. upgrades in those parts that have been upgraded, or changed. YMMV. CYA, BYOB.. you get the idea I’m sure.

Just another morning ‘Air Show’

I see the Airlift Northwest birds all the time. This morning I just happened to have my little Canon S110 camera nearby. The video is pretty horrid, hand-holding a ‘camera’ the size of a pack of cards set to 9x zoom will net just this sort of result.

The point? The noise. And the fact it’s a helicopter, something I’ve been fascinated by since my grandfather first took me to the Heliport (JEM) in Emeryville, CA. I think I was maybe 5 years old. I’m 99.99% certain the place is LONG gone. I can’t find any visual evidence of it anywhere, and the Lon/Lat data I get puts it out in the water. Oh well.

Here is that video anyway.

Two more Videos from MikeysRC – foam FPV flights!

A really cool FPV (flying point of view) video from MikeysRC.com. A scratch build twin-engine foam plane with HD video transmitter. Aircraft flown off the top of a local hill provides some neat views.

Here is yet another cool plane. This time, it’s an all-foam ducted-fan Concord. LOL. The in flight video is great.

Watching these has really inspired me to not only learn to fly Helis, but also R/C planes. So, keep reading to hear more about what I’ve been crashing and repairing over the last two days.

Radio Control Transmitter Research

Following several days of research into radios, price checking, etc. etc., I’ve decided to go with the Spektrum DX6i to get my feet wet with this hobby.

Spektrum DX6i Radio Control System

It meets the minimum requirements for Helis, and it’s available locally for the exact same price as it is online. Which I found really interesting, no ‘better deal’ to be had. I could go into the used market but, I don’t want to purchase anyone’s previous issues. I’d rather know it’s all new and working to maximum possible performance.

Some time around June they plan to announce US distribution of an 8 and 10 channel model. With a clear upgrade path, which I’m sure means I can use the newer radio with an older receiver and, if I decided to get further into the hobby, my old Heli can still be flown with a newer radio, as well as an older one.

Another neat aspect of the 2.4 GHz Spread Spectrum designs are that multiple radios can run in the same area and not cause problems, no cross-channel issues since the radios can bind to specific receivers and visa-versa, removing the need to fly ‘channel flags’ and have crystals on hand so you do not interfere with other people that might be flying nearby. Plus the Spektrum radios are the only ones that work with the Bind-and-Fly RTF (ready to fly) fixed-pitch trainers also locally available.

Pages I’ve read to learn about the differences in transmitters, pros and cons.


Spektrum DX7 vs. DX6i

Here is a good bit of data, detailing the difference between the Spektrum DX6i (the most common recommendation I’ve heard so far) and their updated DX7. The additional features of the 7 over the 6 for Heli pilots is relevant, mainly in the CCPM mixing realm. It’s also a lot more expensive.

Heli Mixes

The Spektrum DX7 offers more cyclic/collective pitch mixing (CCPM) capabilities than the DX6i. The DX6i will operate 1 servo/90 and 2 servo/120 type swash plates. The DX7 will operate 2 servo/180, 3 servo/120, and 3 servo/90 type swash pates.

The DX7 allows you to program 3 throttle curves and 3 collective pitch curves, where as the DX6i has only 2 throttle curves and 3 collective pitch curves. Each throttle and pitch curves for both transmitters have 5 programmable points.

The heli version of the DX7 allows for up to 3 programmable mixes and the DX6i only gives you 2 programmable mixes. If you’re new to helis and need some more explanation of these features, I strongly suggest checking out this excellent RC helicopter website!

Learning to Fly… R/C Helicopters

Learning to Fly……… Radio Control.

Actually, it’s more like re-learning how to fly Radio Control. In my formative years, I had a number of Radio Control cars, planes and gliders. All of them fun in their own exciting ways. One thing I’d always heard over the years, was how difficult and expensive it was to learn to fly an R/C helicopter. Which is, of course, why I’m trying to do it. I love a challenge.

Research shows that keeping the brain (and body) learning new things is the best way to combat age-related maladies of the brain. Having relied on my brain to get great jobs, and even a few times, it’s come in handing finding clever ways to get out of life threatening dangers including things from terrible car crashes to being assaulted at gunpoint. So, my brain is a pretty important thing to me. Fortunately, my work challenges me on a daily basis. I once tried to explain why I sometimes looked so tired after a long day’s work. I’d tell people to imagine taking the semester final exam in the toughest class you’ve every taken, and then do that every day, 5-days a week, 50 weeks a year.

Sure it’s challenging, but really, I’d like to find some fun ways to keep my brain active besides work. So, I’ve giving R/C helicopters a try. They have some a long way since my last adventures in R/C, some 30 years ago. They have come A LONG way. With the advances in electronics, some of the things that made R/C heli flying so dang near impossible for the mortal, are now handled via gyros and ultra-fast response servos, coupled to ultra-light weight electrical systems. Sure you can still buy big 600 and 700 class ‘gassers’, but you can buy the same big birds with high performance electric motors that never need to be tuned up, can be programmed to have very manageable torque curves, nearly infinite and repeatable power settings and of course, a lot less smoke and noise.

That said, flying a modern R/C heli is still NOT easy by any stretch of the imagination! I’ve talked to a variety of people flying them, and the advice has all been the same. Start out SMALL, with one of those indoor CR (counter-rotating blade) models. But get a decent one with a 2.4GHz radio that won’t cause you frustration due to horrible quality.

One specific model kept coming up while talking to people, the Revel Proto CX Helicopter. So I picked one up last week:

How did I get here? Well, there is, of course, a story.

It started early last month on a trip to California with my kids. While shopping at one of those California Super Malls for LEGO, The Boy was distracted by a pair of guys flying little model R/C helicopters around in the mall. He was transfixed. And really, I found it really cool too. We returned to the LEGO store.

I have a system when at the LEGO store with the kids. They have a budget to work within. If they want something in the budget, they can pick it off the shelf and we’re done. But, if it’s more than their individual budget they can lobby the other sibling to pool capitol and purchase more advanced kits.

Sometimes this happen, some times it does not. This time around it did not. In the end, he wanted a LEGO watch (of which they were out of stock). The Girl found what she wanted and we took care of that right away. Upon exit from the store, I was again urged to ‘check out’ the helicopters. I could tell he really REALLY wanted one, and with a birthday only a few weeks ahead, I caved. $40 later we were out of the mall with a bag of LEGOs and a tiny helicopter.

We attempted to fly it outside in front of my sister’s house. It was impossible. It was a windy day, and it was our first time. The helicopter spent A LOT of time spinning out of control and crashing into the ground. It was not long before all the landing gear was busted off and the once smooth rotor blades looked more like steak knives.

Upon returning home in Washington, we flew it inside the house, and much to our enjoyment, found that it flies pretty good when it’s not being subjected to wind! But it was still pretty beat up, flyable but beat up. And I can’t blame The Boy for not taking care of his new toy, I had just as much to do with busted it up as he did, if not more so. And this is how it all began.

I did not replace it right away. Those things are pricey. And I wanted to get one that would suffer a little more abuse with a little more dignity. A trip to the local hobby shop, talking to people online and in person, and a few days later I laid down some $$$ for a little trainer (the Proto CX).

Now, it’s become an addiction of sorts. Flying it all hours of the night, the television has not sat this quiet in quite some time. And that’s a good thing.

Now, today I finally found a suitable replacement for his first heli. It looks like a cool little sport kit, lots of flashing lights and some pretty sturdy landing gear. So now we have three of these little things in the house. Sometimes it’s like a little air show in the living room with little aircraft buzzing around everywhere. Pets seem pretty indifferent, which is fine with me. Less chance of one being stalked and pounced on.

So another adventure begins. Here is a really lame video of my flying this afternoon.

And finally, a neat video from a guy that actually knows how to build and fly these things. As noted in the video, the next step I was advised to take as getting a fixed-pitch heli and nailing down the general skills of multi-channel flight.

Personalized Plate from the Past

It came up in one of the discussion boards I frequent, the question of personalized plates.

Over the years, I’ve had a few. Most of them long gone, and mostly forgotten, but there is one that I did keep.

RC46.COM

This plate was on the first new motorcycle I ever purchased. A 2000 Honda VFR (aka RC46). Yellow of course! Not long after the purchase of the bike, I registered the domain name RC46.COM. I long let it lapse. It was picked up by someone else about 8 years ago. Now it’s parked at sedo.com a domain auction/resale site.

What was fun, is that I did find it captured in the ‘Internet Wayback Machine‘. Here are a few snapshots.:

2nd Generation RC46.COM design. Circa 2001.

3rd Generation RC46.COM Circa 2002.

I don’t think I’ve had any personalized plates in WA. Maybe I have and I’ve simply forgotten. I do run LEM plates on my cars and motorcycles, but they are not really ‘personalized’. I do this for many reasons. One of which is that they are very easy to remember when filling out hotel registrations. 🙂 When on a road trip, not having to run outside to check a plate is just one little thing that makes life a bit easier.
