Electrocuting bigger funflies?

Can anyone advise on electrifying some of the slightly larger fun-fly ARTF IC planes (eg Ripmax Extreme Lite, S2G Extase, Zn-Line Madness) that are out there? I am sure someone here must have already converted at least one of these planes.

My big question is where to put the batteries. With a very thick wing, there is little room above the wing itself for 16+ cells to lurk. Presumably if the batteries are in front of, or behind the wing the CofG will be wrong.

Will putting a lot of cells above the wing (ie right at the very top of the fuz) make the CofG too high? Ie cause some roll instability?

Is it structurally OK to still have a removable wing, and then cut off the top deck to make a 'refuelling' hatch? Or will this weaken the fuz too much?

I'd be grateful for any advice/experience?

this isn't advice but have you looked at the weston cougar? the IC AUW is nearly the same as the e3d and so with endo and 4.6 or even 5.5 ratio as i will be using, you can hover.
not sure how much room there is in the fus but hopefully you could keep the wing loading low with 10 cells.......
are you planning on BL drive trains? they're nice

cougar specs:

£99.99
1300mm span
1150mm long
weight 1.6kg auw? not sure.....

the xtreme light would need some 16 cells..........there's a thread on it somewhere, i.e SEARCH!

Peter - The cougar's a nice plane, but I've already got a Limbo Dancer on the Endo system. (At least I will have again when Ripmax get replacement fuselages back in stock). I'm looking to fly a larger plane.

I am indeed planning a BL system. After getting my first brushless (one of John_E's AXIs) I doubt I'll be buying all that many brushed motors again. I've now bought an Actro motor which will need 16+ cells to run it. I got this partly because I saw a smaller Actro (12-5) flying a Cougar at the Hayes fly-in.

There are one or two threads on the extreme Lite - I contributed to most of them. None of them really answer my questions

Any advice anyone on battery mounting in these planes?
