Emaxx Dual brushless with smaller motors

I've seen a couple of dual motor and dual engine setups. No doubt that when setup right, they perform very well, but never as well as you'd hope they would. Of course, I haven't seen/done everything. I'd love to be proven wrong. It would give me an excuse to venture into a place that I've never, personally, been before.

The real downside is the return on investment. Figure two MM systems at about $400. For the price of a MM esc and Feigao motor, you could still have money left over for a lipo pack and it will probably run as fast or faster than the dual motor setup.

Again, I'd really love to be proven wrong.

Sorry, a small rectification;

The XL motor of the lehner Basic are not 1/10th motors, they are larger; they however don't use segmented magnets.

the more expensive series of Lehner (1920/1930/1940 etc) do use segmented magnets.

Here is a link to the Neu motors; (made in the US btw)

This is not the KV i recommend (unless you want a REAL powerhouse) but you can shoot Mike an email about the other KV values; 1800-2000kv would be nice for 4S.

I'd have to agree. I also like the simplicity of the single set-up. Let weight, less wiring, less maintenance, etc.

OK, say I can be convinced to run a single motor....what is the name of this motor?

[Procharged5.0]

The most trouble free of the single motor combos would be a Lehner 1940/9 with a Mamba Max ESC.

The NEU 1515 is a better motor than the Lehner but works better with a Quark 125b ESC than a Mamba Max.

those motors are plettenberg big maxximum

Sorry, I missed the question (or just mis-read it)


You don't want a BIG-MAXXIMUM. They look really cool, but there are better and more efficient motors available.

[Serum]

Going dual 1940 or 1515 is simple too much. IIRC you want a lightweight setup, go for smaller motors.

[BP-Revo]

I'd say dual 1930's with Mamba Max ESC's running off of 4S each. Should be plenty powerful :)

WOW... two plett's, I wish I had one :017:

Well, I guess two motors may seem asthetically pleasing but its functionally un-neccessary and un-warranted. Besides, what does asthetics matter when the body cover's everything up?
Two BL systems will increase a few things though. They will increase the initial cost, increase the maintenance, increase the weight, and increase the possible failure points. The one thing it won't increase is the performance.

A single motor setup will simply out perform a dual motor setup any day of the week

[jhautz]

I agree w/ serum... dual motor setup is not an ideal solution IMO. It adds a ton of complexity to the whole setup, not to mention weight and wires all over the place. It will look like a very symmetrical spaghetti bowl :005:

A simple, clean setup can be a very beautiful thing as well. I would focus more on quality than quantity.


If you are looking at Lehner motors, the 1940 is more than enough in single format. Dual 1940's would do nothing except shred gears. Cant go very fast with shreded gears.

[Dafni]

I agree with Starscream and Jhautz.

I take simplicity over symetry any day. But I never understood this shelf queen thing anyway.

And with no gain in performance, the decision is obvious to me.

Efficiency is the most important factor when you want to actually run your BL truck.

[Gustav]

all true,but,on the other hand,two MM escs can handle twice the power of one,and since there's a shortage of high power controllers,sharing the work load between two doesn't seem like the worst idea.

[Serum]

Gustav; One mm controller can take the maxximum power from a lipo pack, at a more efficient factor than a dual setup.

Dual is a nono for me. (as well as for other users) but if 0700 wants a dual setup, we need to advise him what we think is best.

[aqwut]

I had duals, and triple setups... I do like the single setup much better. Hey, if you want it to look symmetric, put ur ESC inside the can of an empy motor and mount it on the other side:005:
