N450V2A – post crash repairs underway

Bent tail boom after crash

Repairs are underway, following my flight yesterday, where I ran out of altitude. Breaking things is seldom enjoyable.

But it’s the risk you have to take if you’re going to fly these things, especially when there are gusty winds. There are plenty of YouTube videos showing real helicopters having trouble [...]

N450V2A – Hover Testing

Finally, it was time to see if this thing would fly. And, if I can fly it!

This outing was my best yet! 3 full packs flown, no crashes, no rotor strikes, and only 1 really hard landing! I (of course) shot some video and uploaded it to my YouTube bucket.

Not never [...]

N450V2A Overhaul – Completed

Tonight, I’m picking up where I left off yesterday [LINK], while I listen to some awesome local High School Radio (KNHC).

Sunday nights from 6PM -> Midnight is Industrial and Alt music show called ‘On the Edge‘. Reminds me of a similar show that used too broadcast on KFJC out of Foothill College in [...]

Model Helicopter Blade Balancing – preliminary research

Since I was not 100% certain of the proper method of blade balancing, I’ve started up this page. You see, until 9:00AM this morning I was certain how to properly balance blades. However, after reading the ALIGN Trex450SE instructions, which contain this diagram, I’m not at all certain.

Blade Balancing instructions from the ALIGN [...]

N450V2A Overhaul – Day 1

I’ve had a few good flights, and few bad flights with the N450V2A. After locating a nasty wobble and some incorrectly manufactured parts, I’ve torn the bird down to just about the bare bones and have started a re-construction.

Starting here with this picture, I have already performed the following.

Replaced the Main bearings in [...]

POV Camera mounted on EXI-450A

Wednesday was a pretty good day. It marked the arrival of a mini-DVR camera I’ve wanted to buy for quite some time. It went on sale for Fathers day at nearly 1/2 price. I just could not pass up the deal!

Mini DVR Camera

The location of the aperture is not perfect, but I [...]

EXI-450 Helicopter Build – Day 7 + First Flight!

After fighting with the gyro for a day, I finally cleared the programming on the DX6i and re-did ALL of it. I learned a few more things along the way. This is the final, current configuration that actually let me fly! I won’t pretend to say this is an optimal or even suggested setup, but [...]

EXI-450 Helicopter — Build Day 6

FRUSTRATION!!! Tried to fly but all I managed to do was cause the thing to spin like some sort of evil weapon. Despite my best efforts to solve the gyro issue, it was just not stable! At least the P-51 was treating me well yesterday. Even few it behind a long row of trees (accidentally) [...]

Respect the Rotor

It’s really that simple. Don’t underestimate the smackdown power of a spinning 450 class rotor blade, even if you powered down the motor.

Sunday 13-June-2010 — After 5 hours:

Smackdown after 5 hours.

Monday 14-June-2010 –After 18 hours:

Wednesday 16-June-2010 –4 days later:

4 days later, it’s not painful, just ugly.

EXI-450 Helicopter — Build Day 5

Setting Re-duex.

When I thought I had it all figured out, I learned (in a rather painful way) that I in fact did not. At least no blood was spilled.

OUCH. A 450 blade at full throttle can hurt.

So, after a lot of testing with the heli double duct taped to the [...]
