I saw a full scale replica of the Curtis pusher fly at an air show last summer and believe me it flew very scale likecompared to the mustangs flying that day, I could of run below it and kept up; almost. It is amazing to see how far we have come in 100 yrs. Here's a thought wouldn't a 10-15 mile an hour wind for a model be like flying the full scale in a hurricane or something close to it? I've been bounced pretty goodon some commercial flights.
