Direct Drive to Diff E Revo Build

Nice display of raw power. Congratulation on your outrunner setup (especialy for custom winding your 4130). It would be interesting to log some data with an eagletree: with the rpm sensor you could immediately tell what kv your custom wound motor now has. You really should get one

I wonder what would happen at startup with a jazz 55-10-32 or a MGM 9032 on 10s1p A123 with your factory wound 4130/20 (305kv). Determining the right KV of your outrunner in combination with the right voltage to eliminate cogging at startup with the right esc seems to be the most challenging/interesting part. Your setup seems to do well with a very small hicup when starting up from a near stand still.

BTW: i had the same bearing problems (spiral cut pinion/diff) with my Neu 1512/2Y on 10s1p A123 in my buggy. I changed the bearing quite often. I thought it was due to the fact that the buggy already was 10 years old when i converted it to brushless.
