The only reason for using the eflight 60 amp
1- I know from my exp. that it works
2-motor will pull 54 amps on a 5.0x5.0 CF APC prop

I'm working with Dan to test diff. ESC's in the field and get a list together..... if CC has a swithing rate of 16hz on the 2900kv motor your good to fly...after a ground check of course.

I'll only post what I know 1st hand that works....I want to make that clear. E-flight does make a OK esc. I over amped my 60 (74 amps) for a many flights. It did not fail...it did start not delivering 100% power which was my warning that something was up.

I hope to post more answers ASAP
