“I swapped out the stock power setup with a Mercury 64 all alloy EDF running on a 2200mah 5 cell with an 80amp ESC. A little difficult to fit all those components in, but definitely do-able. The servos have held up great and don't show any signs of stress at the high speeds. This jet is extremely fast and silky smooth.Highly recommend this jet - it is now by far my favorite jet to fly.”
