Brushless MT2 with Mamba and A123 cells
 

My MT2 is just about ready to run, so I though I'd post a few pictures before I take it outside and thrash it. It's currently packing all aluminum GPM components, Mayhem 1/8 shocks, Spektrum DX3 radio, a Mamba Max 4600 brushless system with Mod1 gears, and a pair of 9.9v, 2300mah A123 Lithium batteries.

I'm still waiting for the "Hypersonic Turbo" voltage boost module to arrive, it's backordered at A123. Once it gets here, I plan to run the truck at 14v with the Mamba BEC disabled, and I have a small external BEC to mount that I got from RC-Monster. With the center driveline of the MT2, the saddle pack configuration was the best solution I could find to keep the CG low and the voltage high.

Great work, thats a sweet looking truck. Should be fast too.

I'm interested in seeing how your set up works. I have a Ofna Pirate 10 that I'm going to convert, and it should be about the same weight/config as yours ended up.

Good job! I hardly recognize the truck! It looks like you cleaned up the motor mount and replaced just about every part on the truck. Will you be able to get a gps or radar speed reading on it? You shouldn't have any problem topping 60 mph.

Very nicely done! I was very close to going with this same vehicle, but ended up converting a Hot Bodies Lightning Stadium 10. I used the Mamba Max 5700 and a couple 3200 mah lipos. The thing is insane and I love it!!

Thanks all!

cart213, in hindsight, I probably should have just bought a set of differentials, shocks, and driveshafts off ebay instead of buying your complete truck and stripping it down. Oh well, I'm happy with the way it turned out, and I still have enough parts to build another truck.

I have a hand held GPS that I'll attach to the truck once I get the turbo boost module.

Let us know about the turbo unit, sounds neat. Very nice truck man, very nice. Another clean looking project!

looks very nice, very clean look, nice job

any video of your mt2 brushless ? im looking for that conversion after i finish my rusty !

u can wire deans like that to use two battery packs? i thought u had to do it differently?

Very nice job dude... I can't wait to see how the lithium ion packs work.... full charge in 15 minutes is awesome....

What is the weight of this bundle of joy?

those A123 Packs looks really cool.. but their website doesn't make any sense to me... you figure a 2300mAh pack can discharge at 69A continuous.. but a 4600mAh pack can discharge only 69A ...... You'd think it can do twice the discharge rate....

If I am not mistaken, he has them in parallel, so thats actually 138A. Notice there are 2 packs of 3 cells? If they were in series, that would be 6S.

wow...those batteries seem to pack a punch.....
