Lets not limit ourselves right out of business here Limiting engine size to 120 4c is the only way to go remember 10 cc rear exhaust are a thing of the past witch the majority of the older style ballistic ships call for. unless you have a stock pile of .61's stashed you are already out of the game before it begins (limiting the number of people that can participate in a event). If a club loses money on a event there probably won't have another, clubs are funny that way. 70 inches on the wing span is also the way to go, size of the plane dictates size of the engine. Try hanging a 160 dz on a escape or a blue angel and see how it flies it may have all the power in the world but i will bet it will be a ton nose heavy flying like s&^%.


If your in to flying on limitations you may as well fly SPA a good well established organization.

All i am saying is there are plenty of YS and os 120's 91's and 110's out there, there are a limited number of .61 re's.

Advantage with a 120 is only perceived it all boils down to skill in a pattern event (geometry, straight lines, proper rudder input) IE practice,practice, practice!
