My Revos!!!

Anyway, ran the revo again, for about 40 mins total till the batteries started to fade. Temped everything and the motor was 135f, quark 115f, and the batteries were about 115f. The clutch was cool enought to touch, so I guess that it was wearing in when it was hot, and now seats better and is staying cooler. I am very happy with the temps, so I may leave the gearing where it is. I need to scare up a body for it, looking at a proline f450 body, they look cool. I may go thru it and change out the axles and the dust covers on the pivot balls as they look a little worn. Otherwise very happy with the conversion, and well worth the 130 I paid for it. I will install the sway bars next and see how they do. I may also mount the quark directly to the esc plate to act as a heatsink. All of my equipment is working well, and I would recommend any of it as high end.

Wow, that is awesome runtime. The higher voltage is really where it's at. I guess Iget about 20 min on my 9XL, MM, and 4S 5000 mah combo (have yet to really time it), and you're doubling it, with a higher kv motor! That motor is probably more efficient and that helps but even so, wow.

I was suprised at the runtime too. I have the other revo with a center diff and a 7xl and it gets about 25 mins on the 4s 5k batts. I need to gear it down, it has 20/40 gearing, may go back to the 20/46 as I found some spare spurs lying around. I also have 4 3600 2s lipos that I will make 2 7200 2s packs out off. They are longer than the 5k packs, so the emaxx trays will have to go and some other type of tray fabricated.

lincpimp,
Glad you're liking the conversion. That is some seriously great run time. Your temps look great too. Sounds like you got the clutch thing figured out. Like Matthew_Armeni suggested, make sure the shoes are in the leading position. The clutch shouldn't really get over 130-140f unless there is some other issue.

On the gear mesh choices, if you want a taller ratio, just use a smaller spur gear. You should be able to fit a 17/36 or even an 18/36 in there.

Brian-G, Serum,
I understand the skepticism, but until you've driven it, it's hard to see the benefits of using a clutch system. It actually costs more for us to produce the kit to use the clutch, because there are more parts to produce. Once set up, there is little if any maintenance that needs to be done to the clutch. I'm speaking from over a year of testing experience and results.

BTW, I may have mentioned before, but the slipper clutch is not the same thing as using a nitro clutch. A slipper is a simple friction/threshold setup – no slipping at low RPM, the more power or RPM, the more slippage and heat. A centrifugal clutch on the other hand is quite the opposite – slipping at low RPM, the more power the less slippage, to a point of course. Only under extreme power will the clutch bell begin to slip again, which is perfect. You have the low end drivability, great traction, you still have awesome acceleration and mid range punch, as well as a little protection under extreme load. It’s a different driving profile and much better suited for larger vehicles.

Our goal wasn't to save every last bit of rotational mass for a straight line speed run, the goal was to create the best driving experience for an electric MT, on or off the track. That said, there is no question that it will keep up with any Revo or other electric MT down the straight.

It seems you've already made up your mind about it, but now you know some of the reasoning behind why we developed the kit the way we did.

Yep set the clutch up as the instructions specified. I think that it got hot the first time due to running it right at the engagement point to see how well it crawled! I ran it again today and it ran very well. I need to make some final wiring adjustments and fit a body to it. Then I can really bash it and see how it does.

Ok, did a few things to the revo with the center slipper/diff. I had Artur (griffinru) mod a MM for me. He did the stage 1 mod. So I put that in and added a ccbec. Got rid of the chinese crap bec that was causing some interference. I also bought a pair of trakpower lipos to replace my maxamps 5k 2s packs. Well I can say that the trakpower packs put out a lot more juice than the maxamps packs did. I ran the truck as it was, same everything except the new lipos. Big difference. Then I swapped in the modded MM and the new bec. Steering improved thanks to the ccbec. The modded esc is also smoother and runs much cooler, 25deg f at least. I can now say that I need to put some thicker fluid in the center diff, as the front tires grow to nearly double size on hard acceleration. Good stuff!

I also have a hacker 7xl motor coming for this truck, we will see the difference in power and temps between the two. I also feel like I can gear it down slightly, as the top speed is a bit too fast. I will do that before swapping in the hacker and see how it goes.

I can definately say that trakpower lipos are superior to the maxamps, and the same price. And griffinru's mods are well worth the price too! Plus the ccbec is superior to the generic becs in performance and the adjustability is nice. I have 6 of the ccbec in various vehicles and have no complaints.

I have two of the CCBEC's. I'm very pleased too.

Nice Linc! Sounds like you got some play time today too.

I'm sure this Revo is quite a sight to see run.
