Possible to change gear ratio?
Hi,
I'm about to install a WILD HP03 outrunner on my nano, but I would really like to keep the somewhat low stock headspeed, something similar to that achieved with the stock brushed motor. (This just suits my confined flying environment) I believe tuning it down this low from the transmitter drastically reduces efficiency, so I know I could use a MILD motor instead, but I was wondering if it is possible to change the drive ratio using different pinion/main gear to achieve the same effect. If so, would this method also provide higher torque, i.e less bogging? If this is completely wrong or impractical that is fine, I am mainly just curious.

You want .3 mod pinions like the ones in the link bellow.

+1 for what miracle boy said, but i have never seen a Nano cpx gear with less than 7 teeth (which is the stock/standard #). But it's not like i've ever looked that hard either.

Yea, it seems like 7 is the lowest I can go on the pinion. Anyone ever heard of a larger main gear?
Would there actually be any benefit in running the 16600KV in its optimal range, with a higher gear reduction, compared to just running the 13500KV?

I would assume that the 16.600 sacrifices some torque opposed to the 13.500. Would you run the 16.600 on the same speed as the 13.500 it would bog more under load. Running the 16.600 at full speed, but geared down to reduce the headspead, youimprove torque. The torque will probably be fairly similar. The added bonus would be that the motor itself runs at a higher speed. More energy is then stored in the turning part of the motor. This mean that the motor will have a lower drop in rpm when suddenly applying pitch. This is purely theoretical. I would try it if I had a small pinion.
