Lehner Brushless Gearing?
I recently bought a lehner brushless basic 4200 and basic 5300. I am running these motors on a schulze esc with gp3300's and 3800's. I haven't found any information on how to gear these motors for an Xray TFK104 (drive ratio 1.77). Currently I would like to be able to gear for stock class 27t,19t, and open mod (8t/9t). Does anyone have any suggestions? Any information is greatly appreciated. Thanks!
