Hi,

today was a bad day. I crashed my Velocity90.

what happened: I was flying just as I do all the time. Some mild 3d, some tictocs and some fast bypasses with stall turns.

Now on the last bypass, The heli`s tail suddenly started drifting to one side (nose to the right). I was quite low and fast. And the sudden dirft really scared me - crash and chickendance.

Well, the head and tail have to be replaced, the rest seems to be ok. Just a little dirty.

When I checked the heli after that, I couldnt notice anything strange. All electronics worked perfectly, also the gyro and tail servo.

So my problem is: I dont know what happened, and I dont know why it happened.

i was playing with the gain a bit today. could it be, that my gain is set too high, and that either the servo (BLS251) or anything else got too hot? Which might have caused the drift?Gain is at 70% for all conditions.

Once I have it up again, I just wont feel confident to fly it, as long as I dont know the reason for this one.

thanks for any advise.
