Heya im making up a rigger at the moment and am going to run a feigao 540 7xl in it with a hydra 120 esc, im a little unsure of what size lipo battery to run with it. Any help is greatly appreciated.
How big is the rigger? My xs2 on 4s with a hydra 240 & 4s with the 7xl & x640 prop was 60mph. The same set uo with a 1512 2d is 65 plus. You can run alot harder set ups in the rigger due to less drag. The same set up in a mono would be a disaster.
