Yeh thats what i thought, was a bit nose heavy.. the CG is as per book at 125-130mm from leading edge next to fuse.. so i bit the bullet last night at 2am and couldn't sleep so i started on the attack of the tail lol so i cut back the covering of a part in the open fuse section right near the elev servo's.. and made a mount to strap the batt pack to the ply former in there, re-enforced a few things, made a nifty hatch and bobs ya uncle!! Looks really good to so i'm happy with that.. i hate when you have to butcher something to make it work and it doesn't look like a factory effort, but this does so i am pleased. So now the batt is in the tail i should be able to balance it much easier now.. as for the engine it can't go any further back to the firewall otherwise the thrust washer wont have adequate room from the cowl. So i'll see what i can do now with the batt back there, i'll triple check my CG position and mat even make a small balancing devise to make sure its more precise on the points its balancing on. So we shall see! Thanks MinnFlyer.
