What is the wing area and what is the weight. Samantha and I built a foam wing , profile, no flap plane, full paint. It came out heavy and did not fly well. She can not spray light, don't think Steve will be able to, on his first try. Only letting you know what we went thru, having two light fast building airplane is the way too go. 2015 she lost her plane the day before we were going to leave for the Nats. We had do a fix of a older plane that did not fly well. For three years the Nats have not been to much fun for her, don't know how much longer she will fly, she tells me it just not fun anymore. Would have done things a lot different. I hope everything works out for you two, it can be a lot of fun.
