My revo conversion

[George16]

Well, I decided to convert my 2.5R revo into brushless. It will be powered by a Neu 1515 1Y and MMM combo. However, while waiting for the motor to arrive (though I can transfer the TeknoRC Neu 1515 1Y from the gmaxx), I decided to start assembling the truck.

Installed the Tekno RC conversion kit I bought from James (lincpimp):




MMM V3:






The TeknoRC conversion kit elektri-clutch uses a 2-shoe clutch system. I don't want to run this 2-shoe clutch with a 1515 1Y. Instead, I took out the stock clutch and installed my UE 4-shoe clutch from my supermaxx (retired from bashing and racing duties).

TeknoRC elektri-clutch:


Diameter of the flywheel mounting hole (elektir-clutch):


UE 4-shoe mounting hole diameter:


That's only a difference of .02mm.

Carbon shoes and .9 springs mounted:


Still plenty of room to access the setscrew:

I will be grinding the lip on the 4-shoe flywheel tomorrow. The lip itself is about 2mm so after grinding it off, it will be about the same with the stocker. The UE 4-shoe clutch also used the e-clip just like the stock clutch.

Feedback is greatly appreciated.

Nice set up. Thinking of same set up for my Muggy. Have 1515-1y & MMM. Talked to R C Monster Mike about Motor mount & Bat tray. He also suggested 1515-3d. Running E-REVO w/ 1515-1y, MMM, 2-7.4 8000 Max Amps lipo, plus other racing mods.

Pics.

Will try to send more pics. This is all new to me sorry.

nice setup, i am in the process of doing the same to my revo 2.5r, just recieved my conversion today :D

[George16]

I still have to test-fit the motor mount/clutch after I grind off the lip at the back of the flywheel. I might have to yank off the 1515 from my gmaxx for test-fitting.

I'll be running 4S on this truck once I receive my new lipos from neumotors.

Nice Lito another conversion. Is that MMM the replace you got from CC or you bought a new one. Mine still hasnt reached CC ...

We'll be watching this....

[George16]

Jeff, it's the replacement MMM. Right now, I'll just leave Luciano's ESC on the Emaxx and just transfer the motor until I receive another motor.

Looking good Lito, i still really like those conversions, more so than the actual E-revos, seems sturdier with the metal chassis. Can't wait for updates

I also have a REVO 3.3 w/21 OS that i race when Electric is not allowed. I am in the Sportmans class and by far the best driver but i can cartwheel, back flip, front flip, and tumble and twist with the best of them. My point is that its a REVO plastic or metal nothing twist or broke. What really attracted me to the E was the battery compartments which i wish were a little bigger. Biggest bat that i could fit are Max Amps 2s 2p 7.4 8000mil which I am sure will not last for 30min mains or longer. I still think that it still easyer to change out batteries then to restart nitros IMO.

Here are some pictures of the tranny I modified for the brushless revo. I converted the revo 2 speed to a single speed locked in 2nd gear using an adapter plate I bought from Oomp(one of the guys over at traxxas forum).

Single speed adapter plate:


It was designed for the plastic 2nd gear so I have to dremel the RRP 2nd gear to make it fit.


I also drilled the shaft to 2.5mm so I can use a bigger pin(stub axle pin) for added strength:

1st gear removed:


The assembly:






The top shaft hole was also enlarged to 2.5mm in order for me to use a bigger diameter pin. I used the revo yoke setscrew custom-cut to size.

looks good so far
