Savage Conversion

I have no idea how much it weighs...If I take the hump pack, motor, pipe, gas tank, etc all off it probably weighs a lot less...I'd guess it weighs between 12 and 15 pounds right now with everything on it and an empty gas tank. I don't have a scale though so I can't say for sure. But a lot of NIMH batteries, a BL motor, and ESC will weigh more than the engine/pipe, fuel, and hump pack, for sure.

I've got pictures of what the truck currently looks like on my photobucket.

I can't take anymore recent ones though because the camera has left the building (it was my ex gf's and we split up)

What do you think the minimum amount would be to convert it would be? Or if you know some sites where I can get reasonably priced stuff I'll take a gander for myself - Keep in mind I'm in Canada though, sorry, forgot to mention that :P. eBay may be the best place if it's cheap enough but I kinda need to know what to look for.

How many of those 4200 MAH cells would I need d'ya think? 14/16.8v? 16/19.2v? And approx how much runtime would that give me? Would I be able to make separate packs and run them in series? like 2 7 cells for a 14 or 2 8 cells for a 16? My charger only handles up to 8 cell nimh's, or 3 cell lipos.

I saw posts of guys saying they have 8000 MAH batteries that least 40+ minutes. How much would it cost to get one of those? Would they be nimh or lipo d'ya think?
