Another test today with 2100kv Losi:

45T s / 19T p
Run Time : 40mins!!
Speed : Comparable to 1/10 Gas Car (preparing to change to 5S or 6S)
Temperature: Motor 52 - 58deg cel. after continuous 10min run (still have around 10deg cel room)

6S with your 2100KV motor and current gearing should give you around the same top speed as a gas powered 1/8th. Punch out of the corners is another story, you will leave them for dead!!!

I would love to see some video.

I was planning on running mine tonight against other 1/8ths at my local club as it turns out it has been raining and it also looks like I have to go into work

Last night changed to 5S Lipo, and use Losi ESC also, gearing the same. Test run and found Top speed comparable to Gas Powered 1/8th.
While Out of corner acceleration and start acceleration.... is totally different world ..

Another thing found is after changing ESC to Losi, and changed the timing to "low", also with two heat sinks added w/ thermal glue, the motor temperature dropped to 48deg cel only!! and ESC temp around 43deg cel. after continuous run.

Attached some photos after the changes.... should go to the track for a first run and try to take some video next Sunday.
