You can not add or subtract gears # to makeup lack of speed or torque all that will do is generate heat.either way.now if you want to run 3 cell well the motor better be able to handle that many volts but b4 that a esc will need to be able to run on 3 cells..a lower wind motor will have more...
I've had 1 plug in fail . it was a esc mk3.. it went up in flames on my work bench.. esc only battery was about 110Degrees F .. I had 2 gt esc fail on the track 1 last 1 lap 1 made it 2 then the magic trick was over .who let the smoke out who who.. that was Ko propo
to many cell to run all of those motors those are 2 cell only motors.. if you do run any of these on 3 cells video it I love a good smoke show ...people need to know how many kv to run with each cell. There are known limits from US that have been in this hobby for decades
