Advice for Brushless Setup for HPI Baja

HAHA, I do have a few vehicles, but far from all of them. I do have a savage on the way, which will be one of the last monster trucks still made that I have not converted.

I am actually going to buy a baja ss kit. Not going to convert it though. I have a few large scale gas boats, and really enjoy them, so I think that a gas powered vehicle like the baja would be fun. Plus I have a friend close who has a track setup for the 5b!

If I was going to convert one I would use a large outrunner, some sort of hv esc, and most likely a pair of the milwaukee v28 lipo packs. I may just leave them in the holders and make adapters for them to clip into the car. Not sure if 14s will be enough to move 20+ pounds around. 14s = 51.8v. 3ah x 20c = 60amps cont. 51.8v x 60a = 3108 watts or around 4 horsepower, that may not be enough. I may have to use 4 packs in 2s2p configuration of packs. I am sure that 8hp would be enough.

You would need to do some mod work on the wiring onside those dewalt packs to use them in the case. The wires dewalt uses are way to thin to cary the kind of current an RC uses. Plus you would be acying around all that extra weight of the cases and the crap inside the case you dont need.

Yeah, that is a good point. It is suprising how heavy all of the casing and bs is. Almost as heavy as the cells themselves. Do you think 14s2p would be enough to move the baja around?

I like your idea of leaving the drill battery in the case Lincpimp... although, I would use DeWalt 36v packs, either 2 or 4 packs (with a 10s setup), that way they stay nice and protected, you have built in balancing, and would look plain cool!

I mentioned in the other forum that I cost out a conversion for the SS at something like $3000, IIRC. I used all the best stuff, which you might want in something like this after all.

BTW, Fine-design only has two small lipo packs (he claims 30C....BS), which will most likely be over loaded and/or have little runtime.
