I just finished a GP Super Decathlon. O.S. .50 SX up front with a Pitts. I have set it up per plans, and added all the advice I've read on here through searches. Make sure you read what others have to say, I would not advise this plane for a second plane, but some have said it flies great, so we will see soon! I would not use the .40 LA, at least a .45. Mine balanced about level with the .50, I added a touch more weight to make it slightly nose heavy for the first few flights, I will judge after that, if I need it more snappy. I will let you know, if after today I post in the crash Section. I have 15 years Experience in RC Flying, but I am really nervous about this one!!
