Great information Foxy.

It took me a little time to figure out the differences in old style Turn Motors and newer Brushless motors. I had to do a lot of reading before I understood the conversion and your post helps to educate me further.

I just started to run Brushless motors this last year in my RC10T4 and 2RC10B4s all three were SEeditions with the Reedy 15 Turn motors.

I installed aDuratraxbranded Castle CreationsESC and3900Kv motor in each of these 3 R/Cs along with running Venom 7.4v500040C battery packs than can get about 40 minutes of run time out of this setup.From my understanding this setup is around a11.5 Turn motor and these went from about 25 mph to close to 35 to 40 Mph after I performed the conversions. Crazy fast and fun than almost uncontrollable if I attempt fullthrottle generallycanonly hit about half throttle on thelongest straight. Keep telling myself to gear them down withsmaller Pinion Gears but never do.

Here is a good link for you guys to help you understand more
