mamba max in brushed mode?
 

can a mm esc run 2 titans with no prob.? in a new E-maxx? lmk
phil

it says no brushed motor limit, so i would assume it would run the titans fine. i know guys were running one race e.s.c. like the novak cylcones to run their emaxxs when people were running the trinity 550 motors. i would think the mamba max would be fine.

CC says that in Forward only high power mode it's good for 500A continuous and in F/R mode it's 1/3 that so 166A.

so are the titans gonna pull over 80A each???

I kinda doubt it; 80A @ 14.4v (MM limited to 12 cells or 4s) is 1152w (1.5HP). If the two titans were able to deliver over 2300w, BL wouldn't be as popular as it is. :smile:

ok how would you wire the titans to the mm?
phil

Simply wire the motors in parallel...

RTM! lol.

Whats RTM/

RTM = Read The Manual. When using the MM in brushed mode you only use two of the three wires, but I dont know which ones or in what order to wire them up to the motors.

That's for "brushed mode with reverse". In brushed hi-power mode, you hook all three wires to one motor terminal and the + battery wire directly to the other motor terminal. You don't get reverse in this mode though, but would be more efficient since three times the number of FETs are used.

I hope this diagram helps, I know it's not the best but it's something I threw together. The Green block is the MM, the battery is on the right, and the two titan motors are on the left. You would have to "collect" all of the motor wires from the ESC and make a "Y" to plug the - side to both of the motors. Also, solder another wire to the + on the Deans connector with a "Y" to connect the + side to the motors. Or two separate wires from the Deans connector to each + terminal on the motors.

You cannot get more then 200W from Titans (total of ~400W at 5S), so I don't see any problem using it in reversible mode with 4S.
Wiring would be simple as well, black and red wires only (white not used) motors in parallel.

P.S. High power brushed mode more related to less then 19t motors running at 7-10 cells.

Or, page 9 from the manual has a pretty good diagram. The left diagram is for brushed motors with reverse, and the right diagram is for brushed high power (no reverse)...

EDIT: My post was in response to motoman's post...

Yeah that's true, but I was just trying to show how to wire the 2 motors in parallel. In my opinion it would be a messy setup with a lot of "extra" wires, because I agree with GriffinRU about not needing the high power mode for the Titans. You could just use the reversing brushed mode and it would be cleaner.

thought about selling the evx2 thats in it and getting a mm to run with the titans till I get a BL motor.

That's one of the things I like about the MM; a nice upgrade path...

I've been thinking about getting a Traxxas Villain soon and hopping it up with a pair of 600 brushed motors. They are longer and stronger than the Titan Motors. They produce more torque which will allow me to go up a couple of teeth on the pinions.

I'm seriously considering going with a Mamba Max ESC in brushed mode to power them. Put it on 4S Lipo and it should do very well. I'll probably have to go with a BEC.

What I'm wondering about is, will I have to water cool it? If so, what's the best way to do that?

Nothing against brushed boats, but they suck. Kind of like brushed monster truck, just not enough power to turn a decent prop. Buy a fiberglass hull boat, you will not be dissapointed (the villian is plastic). Plus going over 30mph with a brushed boat and having decent runtimes is very difficult. A brushless boat (sv27) is your best bet. You will have plenty of power and decent runtimes. It is quite easy to get a sv27 over 40mph, good lipos and a x642 prop will do it! Good hull hardware is also a plus, a fixed strut and seperate rudder offer the best performance.

One of my customers made this video for me. I'm very impressed. I can make this work pretty good.

Check it out.

Looks like advertisement :)

I would rather get used plettenberg brushed motor and replace brushes time to time, while having having fun close to brushless :)

I looked into getting a villian, and I do like the very scale appearance of the boat. Your customer's mods are about all you can do with the boat, but since you can get the motors cheap:wink:, and the boats sell for a good price, even new, you may want to give it a try. RCHydros have stopped making their great escs, but I am sure that the evx can handle the 600 motors, it is water cooled, so that helps. The x447 props wil yeild the greatest improvement, but get ready to have fun with the prop balancer! Boats are really fun, however they can be frustrating, especially when you flip one over!

I am suprized at just how much faster that boat is with the 600 cans. I wouldnt mind a boat, but the river dart can be very choppy with a fast flowing tide, so I would need a big deep-v hull to play with, and the cost of building a boat that large and powerful is prohibitive. Maybe an EDF jet would be good, I do have a lazer 6 radio after all....
