RE: Bryce, this one is for you!
Goose...
I have the HET 70mm fan unit, a HET 75 AMP BEC, a HET 2W-20 Motor, and a 4S1P 3700mah pack. I also run a little regulator that I piggy back onto the ESC power lead so I have a direct power source for the RX.
Make dang sure that if you go with this system (even bigger, we have seen up to 2K watts) you reinforce the aft section of the fuse, the area where the stabs mount.
My 16 is completely covered in sign shop type vinyl and i have a piece of rotor blade (full scale) leading edge tape on the bottom for protection.
