[8D] I have acquired a Kalt Whisper Helicopter Main Drive Gear. It measures (aprox) 69mm dia., gear track is 5mm thick, it has 6 holes 13mm., center hub is ~6mm. I haven't counted the teeth, but I have 3 pinon gears; 2x 10T and 1x 12T, these don't seem to mesh.
Anyone have any info. or where I can get info on this gear?
