Re: ECX Barrage Double Motor Tranny yes got a link for servo? |

Re: ECX Barrage Double Motor Tranny What size/RPM motors is everyone using on these dual motor setups? |
Re: ECX Barrage Double Motor Tranny Quote:
The motors are N20 and have gear heads on them. 300 RPMs nice and controllable at crawl speeds. Dual / Twin Motor Mount Kit -- RC4WD 1/18 G2 D90 Body - Club 5 Racing |
Re: ECX Barrage Double Motor Tranny With this setup, has anyone tried running a 300rpm up front and a slower (maybe 200rpm) in the back for 1/24 overdrive/ underdrive? |

Re: ECX Barrage Double Motor Tranny Those of you who have done this swap, did you just reuse the motor wire plug or did you buy a new one? I'd rather not cut the plug off the stock motor just in case I want to reuse this motor. If you bought a new plug, where did you get it? I can't seem to find one. Thanks in advance. |
Re: ECX Barrage Double Motor Tranny Quote:
I always un-solder the wires off a motor for re-use. Never cut. Also you have to connect the two motors together by soldering anyway so soldering the stock motor wires back on is all part of the setup. |

Or are they connected? Do you mind elaborating Shape Shifter? |
Re: ECX Barrage Double Motor Tranny Quote:
Let me clarify my above statement - These motors are direct drive, one motor goes to the front axle and the other motor goes to the rear axle. This replaces the stock transmission. What you are suggesting would require two separate transfer-cases, one for each motor. These axles do not freewheel when connected to the motor gearhead via drveshft. So even if you disco one motor to go only 2 wheel drive, you would be draggin the other two locked tires. |
Re: ECX Barrage Double Motor Tranny Quote:
I have done this on a 1/24 ECX build using a Barrage axle in the front, and a much slower 1/24 Temper axle (worm gear driven) in the rear. It does work, and it climbs obstacles well but the disparity is too great. It’s about a 6:1 ratio. I believe the common acceptable amount is 30%. Here is a picture of that build so you don’t accuse me of not understanding why it wouldn’t work. https://i.ibb.co/JHZpW43/A33-D68-BC-...0-A37-AE55.jpg |
Re: ECX Barrage Double Motor Tranny I still dont understand what Shape Shifter is trying to say regarding this not working. He's said they're both separate, one motor for the front one for the rear. It sounds to me like this would absolutely work. This would be just like an MOA setup in that it has separate motors for each axle. |
Re: ECX Barrage Double Motor Tranny Quote:
I apologize. Your low post count (at the time of your original question) made me think you were a noob. Ive never considered doing that in a micro so my brain did not even think of it in the context of that awesome green rig you built. So, to respond to your original question, now knowing your modelling skills are above noob level :oops:, I can say that the little N20 gearmotors do come with several different ratios, though you would need to do some searching to see if they are withing your desired differential percentage. Have you looked at the Orlandoo motors? They have two different ratio gearmotors for the 1/35 trucks. They will drop right in to this double tranny and may be close enough together ratio wise. Again, I apologize for sounding like a dik.. |
Re: ECX Barrage Double Motor Tranny Quote:
By the way, that chain-drive rig you built is one of the coolest builds I’ve seen. I love creativity like that. |
