hahaha....i've used "the bag" before. no, i'm not going to try throwing a bunch of weight on the tail of my plane just so i can see what happens. that would be mental. and i am indeed a beginner to flying as well. i have six planes of my own ranging from trainers to sporters...ok .....i have a 40 scale cap 232 (many flights...goes very nicely), yak 54 (never been up), a 60 scale cross between a funtana and a 4 star which is a blast by the way, super chipmunk (retired) for now, ... and i'm just wondering what others have to say about tail weight. my planes are balanced pretty much at the mfg's. suggested C.G. and fly pretty nicely as far as i can tell. i know some of these planes seem to like coming in hot and i was wondering if a bit of tail weight would slow them down....along with different pitch props and lower idles...i know there's alot of variables. i will be experimenting with this tail weight this summer and trust me....baby steps are best i know...small adjustments at a time. i've experienced tip stalls with the chipmunk....the cap is extremely snappy....that duraplane with the floats is almost impossible, but it flew...hey, i like that idea of the sliding weight on the flap channel. so...has anyone evr tried this? haha. i can guarantee you i'm not going to do it first. murphy's law is always in the area when i fly..i dont know about you guys. this would be asking for trouble with a sevo control weight adjustment on board...only for me though. i know something would let go. well, thanks for the replies you guys. happy flying .. by the way, this little duraplane 20 is a blast to fly. it's got a 40 size engine with an 11/5 prop. i put inch and a quarter ailerons on the wing and have huge throws on all surfaces. it's an amzing little creature. kind of heavy for what it is. that engine is most of the weight problem but i like the power it delivers.
