Hey guys, i have been looking at pattern birds for awhile now and have no idea what to look for in a go one. i was trying to deside from a Krill spark and a CARF , or just going with a cheaper wood model. so hard to deside.what i do know is i would love to use a countra rotating motor. but which one? i have looked at a few and himax has some nice ones but not sure about power to weight. i do not plan on competing just to have fun with it. and work on my prescision. so what are some thought? should i just find a used one?
