SAB Aluminum Motor Pulley Z22 - Goblin 500/570 [H0215-22-S]

I ordered these parts,because my xk 124,just stopped working. My problem,isn't the esc,or main engine. It must be the mother board,with the built in receiver. I had only ran half a dozen lipo s,through this heli. I did call you guys,rep was very pleasant. He suggested the esc,or main motor failure. It was neither.. Either way,this heli was fairly new.. I just would have appreciated a viable solution. 150 bucks ,plus these parts,waisted on a total of 45 minutes of flight...

Use a gear ratio calculator to figure out what motor pulley you need to run your ideal top head speed at 80% throttle and you'll get better battery life with longer flight times. I run a 22 on my Goblin 500 with an 1100kv motor.

as expected

Great product and great shipping!
