Hi,
I just want to make some estimations for crash costs.
I don't know if some of you crashed their Rave, but perhaps you can help me to make a list of broken/resistance parts in these crashes situations:

-Torque tube in tail blade floor contact
-Torque tube in a hard crash
-Carbon parts (battery tray, frame, fin set) resistance in hard crash
-Canopy (paint, fiber) in medium and hard crash
-Frame alloy parts in hard crash
-Landing gear in hard crash
-Main Rotor alloy and plastic parts in medium and hard crash
-Tail rotor alloy and plastic parts in medium and hard crash

I certainly forgot things. Blades, shafts, main gear, tail boom are almost always in the list.

Thanks for help.
Jean

Some will take me as biased but you can take my experience for what it is. I have crashed the Raves more than anyone else up till this point. I have only broken the torque tube once. I accidentally did a blade stop with the Rave at a demo in Mexico. The blades folded back and when I turned the motor on it cut the tail boom in half. That broke the tube drive.

But in normal, even hard crashes the torque tube does not tend to break. If you strike the tail blades on something hard like a rock, or wind up the tail blades in thick grass stopping the tail with power on, you strip either the front or back tail gears. These tail gears take only a few minutes to swap in new ones and you are back in the air again.

In normal crashes I tended to damage the main shaft, cross shaft, tail output shaft,landing gear, flybar, tail gears and carbon fins. In that order. Most metal parts hold up well to crashes. You might strip some teeth off the main gear if you hit the ground with full power on.

I hope this helps,

Curtis

The one time i got tangled in grass, the only gears i broke were the front gears, not even the bevel ones. I was able to replace them without removing the tail boom. I have crashed once and it held up quite well. The canopy broke because i crashed nose down, but it wasnt that bad, with a little bit of fiberglass, I was able fix it, and now its my beater canopy. my TT and lg were fine.
Hope this helps,

Thanks for this very precise report Curtis. I think you flown your Rave a lot And because parts are directly available for you, you can take more risks, so you crash more. So these are good statistics of parts which broke depending on crash situation. It helps me a lot. I'm pleased to read that thoses are not the more expensive.
I'll build a wood area for hovering and landing to avoid tail gear striping.

Pleased to read this too Littleman, it seems to have a good crash resistance.
Thanks.
