The KV is too high for a 55mm GWS fan 4200Kv is 'about' right for 3s even 4s if V careful. No wonder your heating things up with those. There is an ADH 300 in 4200kv buy/use some, these are decent motors when the suitable KV is fitted!!
I hawe a 250 GT helicopter with Turnigy 2623 MOTOR. I can not find any pinion gear that fits the motor. I've tried 3 different pinion gears. but none match the teeth of the gears on the helicopter. Please can someone help me? which pinion gear should I buy?
Hi! if you have the correct gear mesh for the pinion and main gear and the pinion hole is too big or too small for the shaft, here are the solutions that worked for me: 1- If the hole is to small, just make the hole big enough to go into the shaft with some pressure. 2- if the hole is to big use some strands from a copper cable (if you have puffed lipo batteries that you are not using anymore the cable strands will work really good) to fill the gap between pinion and the shaft and use red treadlock to keep the pinion and main shaft from caming apart. Cheers
Just connect each one togather one to one then start your system and check whether it turn in the correct direction as your need it to be but if it is not then you just swop two pairs of the wire. It should be turned correctly.
