I'm looking for help . I don't fly but I got a hummingbird V3 in a trade with a on road car , but if I tern it on the two motors start spinning out of control and all the servos start to chatter . Iv bin in rc for a few years now and I stick to the dirt but I know enough that the receiver is no good . So my problem is , I'm looking for a new one to replace it but I have no idea what to look for . The stock one is a receiver, gyro all in one and I'm looking for one like that . Unless one of you people out there wants to by it from me for $135.00 shipped lol . Pleas help thanks .

try e-sky ones they are not too bad for the price (10~20 bucks)

To rule out the possibility of it being a setup error try the following: This is a standard procedure for all 4 in 1 recievers. You must set your throttle trim all the way down, and set your throttle all the way down too, then connect the battery to the reciever and wait for the 4 in 1 to arm. Obviously if the heli goes mad then throw the reciever at the guy who robbed you!
