I was just wondering if you can modify a plane that is capable of competing in SPA such as length of wings, length of fuse etc. Does it have to remain completely original? Any info would be greatly appreciated. By the way, does anyone know if a Dalotel is a plane that can be flown in SPA? Thanks guys.

Errr.... SPA? Forgive my ignorance....

SPA = senior pattern association

Here's what it says from the website about altering planes:
a: Any model designed and flown before January 1, 1976 is legal

b. Aircraft must be built to the plan form of the plans.

c. Retractable landing gear, flaps etc. are not legal.

d. The contestant is responsible to furnish documentation for any model not on the Legal Airplane List. The president can provide the member with Legal Airplane information.

Best regards,
Scott

Thanks for the info.!!!! You've been very helpful. Hope your flying days are filled with many happy landings.
