I fly a very battle tested Dynaflite PT-19 with a Zenoah G-26 up front, turning a 16 X 8 prop. Shifting servos and battery around inside will enable you to keep the CG where it should be. Nose overs are typically corrected by re shaping the landing gear so that they are kicked out a bit more forward....it worked well enough for me. I use Robert struts too...that absorbs some of the impact force when your landing is harder than you would like. We usually fly a number of them in a gaggle during warbird or big-bird events. We had 13 planes up at in a gaggle one time. All of them in the standard yellow/blue scheme. Some guys would add a very large number on the fuse to help identify their own plane. It's a sweet flying plane...no bad habits...kinda like a low wing Cub. I have been lucky enough to buy a new kit online...but it cost me $300. That's my backup in case I lose my current plane. It's amazing how these things have become so much in demand. You'd think Dynaflite would reissue it. Even Great Planes should consider re-issuing their ARF version.
hope this helps you guys.
