Hey Tom I have an Idea that could make you money. Design an ARF that is just like the Stinger .10 nobody makes an arf that will perform like the stinger .10 with a .25 or .32 and a pipe. Fastest and most out of control plane I have seen in 35 years. I know I would buy 2 or 3 of them. I also know alot of people looking for them online but nobody has one forsale not even a built kit. You could sell hundreds of them. Just a thaught.
