blet cp problem?
 

hi, i have a belt cp. I'm new to this and crashed my heli a while ago. Then, it started having a strange behaviour: you hear the rpm go up and it squashes against the floor. Then, i noticed that my main shaft ( do you call it that way?, its the peice that keeps the main rotor in place) was bent, so i changed it, people told me that that was the problem. After that repair, the same thing is happening again. I think my servos are all right. Is it a glitch or could it be someting else? Ah, I fligh the heli about 30 cm off the floor. I dont know if it could also be wind. I fly outisde and inside and it happens in both conditions

thanks

that sounds like you battery to me. Check you
battery, voltage on each cell
receiver take it apart and see if anything looks damaged. Don't lose a single thing though.
and ESC. how hot it is after couple seconds of spin up. anything burnt? etc
Also check everything on your head parts and look carefully on your tail. Even slight crash can bend, break or disconnect something. I crashed my belt-cp on easter and it wasn't hard at all! and i lost a bunch of head parts and then the tail boom was bent. I was surprised because taill boom took quite a bit of force to bend back to its place..

The part you are talking about is the spindle shaft. Are you in idle up? If it is squasing against the floor you have negative pitch. I would recommend to check the pitch of the blades. You could have ground wash that low to the ground. If you have the stock transmitter check that the knobs are in the right spot. Druss had a good explanation about what each one did.
