RE: helimax help
Most people I know would suggest the electric TREX.
I have a shogun but they are virtually the same flying characteristics as the TREX
They are all built around the same sort of size zoom 400 , walkera, Trex, Shogun. So if this is the size I would find out where your local parts store is. No joke. If your closest dealer is hobbypeople get shogun if its a TRex dealer get the Trex.
if they were about the same I think I would get the Trex because I hear they're about the same as the shogun but have cheaper repair parts.
