Twins with single drive?

[Brushless55]

Does anyone know if someone makes a drive setup to use two 540 size motors driving a single shaft..
I would like to try this in a cat that is setup with a single drive..

Thanks

I was thinking of this...you could modify an emax or erevo tranny to work

The tough part is to engineer a pinion gear that can free-spin if one motor cogs, blips or otherwise shuts down for some reason (ESC failure let's say). But then you're left with 1 motor doing the work and instantly getting an amp surge, which will probably take out the other ESC.

You're better off going with 1 bigger motor...but I know, the man in you wants to try it!

Have a look at this. We use this in scale boats. 1 motor turns 2 props counter rotating.

The old Super Hawaii used that set up. It would bolt up but the gears are for 1/8" motor shafts Not sure how well they would do but I ran mine on 12 -14 cells and never came apart.

My Kyosho used such a setup but that was for 1/8 shaft brushed motors and 4mm drive shaft with a 2:1 gear ratio. I haven't heard of one being used for brushless applications.

Well I am going to keep looking, and if anyone has any pictures or info please let me know..
two motors into one drive..

Thank you

You might want to call Ray at Fuller's Fast Electrics http://www.drcwebservices.com/ffe/ . He used to sell a transmission from Hughey that Ran dual 550 motors to a single shaft. MRP used to use the same thing on their Hydros. He may be able to point you in the right direction.

Is this what you're looking for?

Ed may still have some duals, I do but I'm holding on to my Hughey stuff. Maybe Fluid (Jay Turner) has one. I even have one that will hold 4, 05 motors!

I believe this way is practical a few years back when motors are weak, brushless are not as popular as today. See what happened to E-REVO original to E-REVO BL, and you get the answer.

Thanks domwilson and sjslhill and jeff, getting good stuff..

My question would be WHY ? unless you are planning to run brushed motors ? ?

There are some huge brushless motors that are capable of pushing big hulls at 80+ mph, why would you want to possibly complicate things by running two motors, two ESC's , two sets of cells, gears, etc etc, to me it seems like that would be introducing more possible points of failure and cost for a single drive.

Also consider the Gearboxes that you are looking at are most likely designed for brushed power and will probably FUBAR themselves with any good amount of BL power.

Please don't take this the wrong way, just stating my opinion based on my own logic

[Brushless55]

because I want to....

[crabstick]

just because huh...

I wish you good luck and await the result!
