[8|Thanx for all the input. I maidened my nitro seawind yesterday , now i have read all the threads on this plane and most problems are getting of the water. But there are some questions regarding CG. I have the CG as per instructions but it seems that these are no good. this is what happened. I straight away needed a lot of up elevator to stop her diving badly.I have built and maidened many planes but never before was the trim so far out that I could not trim it in flight without help. I could not let go of the stick and trim fast enough,she would dive straight down,but if i tried to climb she would shoot straight up. it was as you say as if elevator was to sensitive but wildly so . But the tendency to dive confuses me[:-][:-]
I managed to land with great difficulty but she did seem better with engine cut and flaps down. The factory CG is 90 mm, I need to get it correct before I try again as I dont think I will be as lucky a second time.
Suggestions please...[&o]
