i was starting up my heli today and everything checked out fine. i had full control of cyclic, rudder, throttle, and pitch. and then in the middle of spool up, i lost total radio control and the heli kept spinning its blades on the ground. thank god it was at low rpm and sat stationary. then after maybe a minute, i regained tx control and shut her down. i'm puzzled, this is the same basic setup i run in all my helis. here's my setup:

logo 14, cc 85hv, futaba 9chps, r319dps rx, s9650's, tp 10s2p 4200mah, gy401 s9253, ubec 6v, and jr servos extensions.

any ideas?

thanks

check the pots on the 319dps. They should be locked in place. Antenna still firmly connected to the reciever board? Extension and connectors should be firmly attached.

I would think its not reception problem, because if it had been, you should have go into failsafe, shouldn't you? That is unless you have not set up your fail safe and have throttle at last position for failsafe. You might want to check your ubec and the switch connecting your ubec. I know there is battery failsafe, but if there is a sudden lost of power supply, it will not go into batt failsafe. I had it happen on a nitro, power was on and off, sometimes my on board battery checker will go on sometimes it goes off, all between a few shakes, ended up it was the battery.
