Finally getting round to converting the hyper 8.5 to electric, using the standard 46 tooth spur, I'm using a goolrc brushless 4076 2000kv 4 pole motor with a hobby wing 8BL150 esc, what size pinion would you recommend as im totally lost after reading so many different things, I'm thinking 18t would be a good one to go with, unless that's too high for this combo, I intend to use 4s. Only used for general bashing.
