My head is still swimming after reading your post LOL Would I have room in that plane for 2 batteries?
Re: Swimming

It's pretty simple math to figure this stuff out.

Try following my example and you'll find that you can work out the numbers yourself.

Re: Batteries

Yes easily.

Those two packs will weigh less than a glow motor and fuel.

Your biggest problem will be:

- Access to the battery packs, e.g. you'll need to remove the wing to install and arm the packs.
- Motor mount, you'll need a motor mount to replace the glow beam mount ( hint: Great Planes has a WONDERFUL electric mount for this purpose! )
- Balance, the battery and packs will weigh far less than what the plane is designed for. You'll need to move things as far forward as possible and maybe add additional weight.
- Charging: ( more packs and a nice LiPo balance charger are in your future if you go this route )
- "Tuning": with engines we do this by ear, with electrics you'll need to buy a WATT meter to figure out what is going on.

Note: I purposely refered to this as "tuning", really it's more akin to "testing so you don't blow anything out by using the wrong components".
