GG good point but for a nitro guy its difficult to make the switch when you look at a plane on hobby lobbys site , you see the plane for $250 , engine $100 , speed control $150 , ok not bad so far , then you get hit with batteries needed 2 , cost per pack 370 [X(], so I know they can be used in more then one plane and trust this plane has my interest , I just wish pack would come down like all the other tech RC advancements
