I'm ready to try my hand at 3D flying, so I bought a ultimate .40. I figure not too big, or expensive.im not sure if an OS .46 Lawill be sufficient, but I bought one. Anyone know if it will be enough? Keep in mind, I've been a scale flyer all these years, so I don't think I'll be doing any thing too crazy at first. Any suggestions on prop size? Thanks in advance to who ever kicks down some knowledge.
