Touch as nails stab

I had a little mishap at the field yesterday. I'm not really prepared to admit fault entirely - but I will say that just before the plane nose dived in to the ground after starting a wot straight down decent, I was heard saying "I'm not afraid"... I think I was trying to show how strong and stout the new motor was.
 
When I found the plane among the broken parts I realized that the stab control horn was hot glued on. Well it was not hot glued anymore let's say.
 
So thinking that maybe this might have played a roll, here's how I rebuild the stab control horn.

Bamboo pushrods

it seemed neat to try the home brew push rod formula. Normally folks use carbon. But I'm all out of discretionary funds. So I am trying out bamboo. This is wire wrapped once by itself in thread with ca - then aligned to the bamboo rod and then wrapped again hard. 3/4 to 1 inch of wrapping. Finished off with 5mm heat shrink. I used thin ca thinking that would soak in the thread and bamboo better.

The bob is on weather hold

Notice the cat whisker like bamboo sticks strategically located about the underbelly of the bob for holding rubber bands for the battery. Stakes were installed over a epp shelf for the receiver but the receiver has not been banded on just yet. Sent via BlackBerry by AT&T

How to tell if your brushless motor ever got too hot

I learned recently that if you over heat a brushless electric motor, you will weaken the magnets - which in turn weakens the motor.
 
Here's one sure fire way to know if you overheated a motor: the motor mount melts.
 
I thought it would be cool to take some video using a way too heavy camera. I was full out in the throttle trying to keep the stick in the air for the whole 5 minute flight. And this is what I have to show for it..
