Gearbox Noise - is it normal?
Just finished my first Electric ARF and am using the Great planes 5:1 ratio gear box (non bearing) on a Graupner 7.2v 400 speed can. On powering up the engine hums at low stick input before spinning the shaft and then the gearbox gives out quite a bit of gear noise when running.
As this is my first electric im interested to know if this is the norm for plastic gearbox operation.
Cheers
