Dual Titan 775 E-Maxx Project

I know that brushed motors aren't very common around these forums, nor are they very common around my stable of RC cars. I did however elect to stick to brushed motors for this project in order to make a waterproof powerhouse.

I used a pair of EVX-2 ESCs to power two Titan 775s. The result is a Torque monster with a higher top speed too.

Looks like you're having fun with it...

I would recommend the use of WD-40 in the motors after each run to keep water from sitting on the bare iron components. Of course check all of the other metal chassis parts for rust once in a while, too.

Looks nice.

Isn't it possible to use only one of the esc's?

Each Motor uses four power wires (2 positive, 2 negative) as they require a fair bit more power than a single 550. I could have just used one ESC by combining the wires but I likely would have fried the ESC in a real hurry. I'd also likely lose power at full speed on a single ESC.

Basically Traxxas designed the 775 to replace two 550s.

I see, then I learned something today.

Basically, I likely could have done it, I just didn't want to risk it when I already had a spare EVX-2. No sense frying an expensive ESC if I don't have to.

I was going to ask why you used two EVX-2's until I read that you had them laying around. (Based on the ratings of the EVX-2 and Mamba Monster, you could drive both 775's with just one Monster.)

Looking good!

I tend not to trust ratings on brushed speed controls. I've nearly burnt out a couple XL-5s running on 8 NiMH cells even though the specs say they can handle it.
