Made some changes. First off, I had to shorten the chassis by 8mm in order to use dogbones that I could find; although I may have found somewhere to do custom dogbones so I may change it back.
If I looked at 3S, or 6S, I could definetly fit doubles within the frames, but would need to have the batteries (obviously with 5 or 6S block; 5S being what I'm running now) positioned over the drive shaft. As part of the process of creating new frames, I wanted to reduce the CoG so was hoping to run the batteries on either side of the drive shaft low in the frame. This meant 3S batteries. There is about 30mm clearance (driveshaft is thicker than the standard Savage) on either side of the driveshaft which is enough for most 3S 40C ~5000mah batteries.
But with the Mamba XL having come out, and having 8S max with motor braking, I wanted the ability to not only run 6S but to also run 8S batteries. After sampling the various 40C or above, 5000+ or above 4S batteries I realized I needed at most 50mm wide area for the batteries. Unfortunately since the Savage TVPs are only 73.75 mm wide from inside to inside, that means that two 4S batteries won't work as most of the batteries were around 40-45mm wide!
So what I did was refactor where I was going to put and mount the batteries. In the forward section, I create two cutouts that leave room for two 3S or 4S to sit on either side of the driveshaft. The cutouts mean that the batteries will extend beyond the TVPs, but that shouldn't be an issue nor should the cut-outs as I plan to use 4.5mm carbon fiber for the frames. A bottom plate, cut out of CF again, will act as the battery holder and as a skid plate of sorts too.
Will need to create some type of guard that surrounds the outside of the batteries and attaches to the TVPs to keep the soft packs from being damaged; either that or will need to construct some battery shells for soft packs or just use hardcase 3S when running 6S.
