I see where you guys are going with finding all the weight in the nose, the cowling, prop and spinner weigh 10 5/8 oz. I have pretty beefy screws and nuts to secure the engine to the mount. The prop is a K-series Master Airscrew 15 x 8, can use 15 x 8 to 16 x 6 props with this engine. How do you go about getting a lighter cowling?
I think relocating the battery towards the tail shouldn't be that difficult.

Yes, the moving servos would take some work.
I think cutting in like GB has done, then making a hatch for battery access would be very easy, or just patch the covering once you like the battery placement. it would be very unnoticeable on the bottom of the fuse.
good luck
p.s.
I too have had those spinners blow up on big 4 strokes myself, it happens when the prop slips on an engine backfire,, be cautious.
