So heres the deal- Im 65, restarting control line after 55 years, when young could only afford 049 stuff, was advised by an another old control liner not to start with an 049 plane so I got a ARF Flitestreak put an old Fox 35 on it, used an old EZ Just control line handle and crashed and crashed and crashed until I decided to go another way. So I relearned on a 15 powered plane cobbled together and now have a Supertigre 40 powered plane given to me by another old guy; It is a flapless homemade stunt plane. My questions are: This plane weighs 46 ounces and takes about 25 feet to do a loop. If I speed up the controls to tighten it up I get into the PIO mode. Would a lighter plane loop better without being oversensitive? How about a plane with flaps? I can go round and round ok and do inside and outside loops but it gets close to the ground sometimes. I know Im older and slower but eventually I hope to get some modest proficiency. Advice please
