Since I am just starting to get back into CL after many years in RC, I cant speak with a lot of exper. about CL ARFs, I do however have quite a bit of exper. with RC ARFs of all sizes and I have yet to see one that didnt need at least a few changes, mods, repairs, etc. done when assembling. I know we tried to keep CL airplanes as light as we could back in the Fifties and Sixties but with todays competition and designs, acft weight has really come to the forefront in importance, that being said, when you consider the airframe stress from CL(or RC) aerobatics,there has to be a balance between weight and strength so some beefing up of stress points, glue joints, loose covering etc. seems to be the norm rather than exception, if we dont understand the "whys" of this and complain too much, the ARFs wont sell and the manufact. wont make them and the only ARFs left will be trainer types. Just my thoughts on this. BOB
