The SPA has no limit wingspan on sportsman and expert. It was abolished to include the King Altair 80". The new SPA Altair is 74" and not 72. If you read the fine print the 72" limit is for the novice division to keep 1/4 scales and such from showing up. The 80" King Altair is about the max for the engine specs to haul around. The dirty little secret I've been told is the 80" Altair is barely competative with a good strong 91 on it. The 74" version is a better match up.
