MCD MT "clone" 1/5 Conversion

[Takedown]

Ok guys yet another new plan/idea.... I ditched the tranny and will be going directly off the center diff. But heres the catch. I will not be running a setup you guys are thinking of with a pinion meshing with the diff gear. I removed the diff gear completly. I will be running chain drive. I will purchase both the pinion sproket gear and the center diff sproket gear here- http://www.electricscooterparts.com/sprockets.html I will be buying a 11t #25 chain 8mm bore and a 14t #25 chain 8mm bore sproket.

Also here is the final specs of this setup...




I also found some really cheap wire "10awg-8awg" for this project- http://www.electricscooterparts.com/wire.html

Sounds good. Have you looked into spending a little extra $$$ on A123 cells and making a nice pack out of them. I know a 10,000mAh 25-30C 10S lipo packs would weigh about the same or less then the lead acid packs. Get your self a good ESC that will handle the current loads and your set.

Looks like its coming along good so far Ryan, although I still think you should just leave it a gasser......

And that motor you showed me on AIM is a beast.......

I think Im stuck on PB's because of how cheap they are and how easy they are to maintain. I found a 100a HV ESC on Bidproducts website for $30. Its 10s capable so that should work fine. I will be using Mech brakes aswell.

Will the PB's handle the current load though. Here is a nice little video to show you how a starting battery pack made of A123 cells does: http://www.youtube.com/watch?v=lyYBh4ec05c. Here you can see that they want to be rich real fast : http://www.tekbattery.com/battery_prices.html. All you need is 4 of the DeWalt packs and do a 10S4P set up. Will pay for itself down the road. A 9200mAh, 36V A123 packs will put out 276A continuous and 552A max if needed and will weigh much less then the PBs you plan on using.

If I had to choose some motors, I would go with the following with 8mm shaft:

http://www.hobbycity.com/hobbycity/s...utrunner_193Kv

Now these have 12mm shaft, but would also be good motors for this project:

Im already getting the brushed behemoth motor. The 100a HV ESC will also be on my list and the PB's will most likely be my choice. Im on a budget.
