RE: E Flite Eratix 3D 25e ARF Owners Club
I use a 4S 3300 mah pack and have been running mine with a 13 X 6.5 APC prop.
I've also used a 12 X 6 and it works rather well although I prefer the 13 X 6.5.
Next trip to the LHS I'll pick up a 14 X 7 and see how it performs.
I really like this plane! So far, the easiest one to hover.
