https://www.youtube.com/watch?v=fBetp3Uw-uEWhy is this making this noise i tried this with 2 esc and still it does it i thought it was a bad esc but a brand new one out the the bag and one thats 3 weeks old that i took of my belt cp can't me broken Maybe its a bad motor but it seems that it don't make that noise when i take my main blades off and throttle up with just the fly bars motor brand new maybe its to cheap of a motor i dunno im orderd an alfa 400 exceed but when it came in the mail it was the silver and black motor colors and i e-mail xheli and they said it had the same specs but to me it looks cheap i dunno 3500kv


why the noise can't be esc tried two differnt ones and same problem
with noise and the esc 30 amp

i gave of on it i think maybe it had something to do with the cheap motor i just ended up going to hobbyh store a picking up a align esc and motor an wow sooo nice smooth

Andi thought it was the one way bearing or the main gear

Hey burton if you are using the volcano esc put the satart mode on soft and the motor will work fine.
