Martin Harris - Moderator Posted September 13, 2009 Share Posted September 13, 2009 Just be aware that although Eric's rule of thumb will give reasonable results in most cases and I've no reason to suppose that the Gambler won't respond well to it, it is just that. If the layout is less than conventional on another model, the tail area and its moment may start to become significant - as an extreme, a tail-less model may need a C of G position at perhaps 5% mean chord!

Dusty Posted September 13, 2009 Share Posted September 13, 2009 Agree Martin, 1/3 dont work on wings with tails like (bobcat,falcon etc whatever you want to call them)... Steve, quick google of your model type there are some threads on RCG, no offence to RCM&E but he is looking for a quick answer? It aint here yet so ut might be there...

Martin Harris - Moderator Posted September 13, 2009 Share Posted September 13, 2009 Steve - why not try a call or email to Ripmax? I've found them quite helpful in the past. Quote Link to comment Share on other sites More sharing options...

Steve biplane Posted September 15, 2009 Author Share Posted September 15, 2009 Thanks all for your replies, especially Eric for taking the time to write down a general way of working out a safe C of G position as a starting point. I will try Ripmax and see if they still have the info on this old model. Regards, Steve Quote Link to comment Share on other sites More sharing options...
