So far I did some testing with Li-Ion batteries and Li-Poly batteries.

Lastest one with 1500mah LiPoly pack.

1. How many amps can the stock ESC/RX take?
2. Anyone try another prop?

I am pleased with these, my goal to stay as stock as possible for fun running with my 2 sons, Andy and Matthew

thanks,
Steve
