Duel hvmaxx - 04.18.2007, 12:19 PM

Just purchased my second HVMAXX system for my E Maxx. Has anyone here ever done this? I bought a new chassis to handle the four batteries and plan on mounting the speed controls piggyback. In the future I will probably need to upgrade the tranny gears and drive shafts.

Welcome to the forums!

Yeah, bual BL systems have been done. I think Johnnymaximma (or something like that) did it, just not with HV systems.

Generally people just go to a larger single motor. Its cheaper, lighter and easier instead of having 2 controllers, sets of batts, etc.

You can have one ESC and two motors...

I had 2 HV-Maxx's in an e-maxx with 28 GP3300's (14 cell's each).It was ok, faster than a MGT 4.6 and Savage 25. My Neu 1515 1y on 4s or a 9xl on 5s is faster and has more torque though. I short I think it would have been better to go with a BL combo that Mike has listed in his store. (BTW, I got 1 HV-maxx for free:027: )

:O, It's always fun to try duals... :)
I've done duals and triple brushless.. and I agree... 1 nice motor is always best.. :) JMO

Number of motors doesn't mean anything...
It is possible to make a killer system with any approach, you just need to know how and what is the difference between one and another!

None of the sensoreless systems will outperform sensored setup in torque ratings at zero-to-low RPM, but then you can always compensate with motor size :)

Number of motors can be dictated by application and space limitations as well as price

I can see dual motors being hard on an ESC if both were highly inductive. Plus, I would think that a single motor would be more efficient than a single, properly sized one. After all, you are doubling the amount of bearings and drag for the mesh, right?

Yes and no, more torque les time takes to accelerate, less time ESC under load...
And, with proper setup you can double(triple...) number of poles... More poles more torque...
But everything depends on application, right
