Anybody have any experience with the Tekin RX8 system? I can get it with a 2650Kv motor and run up to 6s lipos with it. http://teamtekin.com/rx8.html
The castle creations mamba monster systems get really good reviews but the Neu-Castle 1512 1Y 2650kv motor can only handle up to 4s lipos according to their website. http://www.castlecreations.com/produ...le_motors.html

If I am going to reach the speeds I want I will need the highest rpm possible.

Tekin- 2650Kv x 25.2v(6s) = 66780RPM
Castle- 2650Kv x 16.8v(4s) = 44520RPM

The Castle system also costs $449 where as the Tekin system only costs $349
I havn't had any personal experience with either of these brands but I thought they were both pretty good. Is the castle that much better quality wise or are they about the same? base solely on the numbers the tekin is a better buy. Am I missing anything here?
Thanks
