That is looking awesome.

I'm wanting to convert my Revo to brushless using the GorillaMaxx chassis real bad now.

Do it!! I have seen vids of the G2R conversion and they are sick!

Ready for test run in the morning.

I got her all wired up tonight. I decided I didnt want the ESC ziptied to the chassis and exposed like other 1/8 brushless. Found a small black project box at Frys and stuffed her in, along with a pair of heatsinks and novak cooling fans.

Wiring looks like crap. After a few packs I'll have to figure out a way to clean this mess up.

Nice job on the esc box, it looks good. Now go make a video of it tearing it up!
 
wow! That looks awesome....
There was a conversion in RC Car Action a while ago, turned a Revo into a brushless race truggy or something.....
 
The only thing is your going to have to run with a body all the time. You wouldn't want to rip off the box or anything!
 
Jeez, that thing is cool lookin! I gotta say though.. I don't like that ESC box up above the chassis like that.. not really because of the weight but for durability like Ben was sayin. That thing lands on it's lid and that box is gonna take ALL the abuse. Is there enough room to turn it on it's side and shove it between the vertical braces above the front center drive shaft? probably not, but that's what I would try to do. Helluva nice job configuring that box though.. very nice :thumbup::thumbup:
 
Very cool looking rig. Like I said before, I WANT A VIDEO!!
I'm anxious to see it gooooooooo.:jet:
 
Nice looking rig.

You should re-think the box and fan design a little.
The way it sits there isn't a full path for the air flow. Depending on your fans it looks like you are either blowing or sucking air from the front of the case.

In a perfect world you want the flow in one end and out the other with a majority of the flow path over the sinks.

In the photo it looks like the path is blocked with foam and there is no port on the other end to complete the path past the sink. You could remove the foam on the sink side and drill some holes on the rear sink side of the box. Icing on the cake would be filters over the front of the fan.

Nice F-n Work!!!!

I'd think more than icing... It doesn't take much dust to eat up one of those little fans. If you perfect a filter, hit me up, I'd score one to stick on the back of my computer tower... j/k

Looks awesome !!!
 
Thanks guys. The black box has a small hole in the back of it right behind the heatsinks and also a large opening underneath in the rear. The fans suck air in from the front. I do need to rethink the foam blocks. I don’t know anything about heatsinks, can I assume they work better with air flow closest to the base? Maybe I should have the foam blocks running completely across the top of them to force air through the heatsinks. Screens are a great idea. I happen to be going to HD so maybe a small piece from a front door screen would be sufficient.

Ben and Lessen, I tried a few different ways to mount the esc box, my first was to try and mount it on the side of the chassis. I couldn't get it to look clean. I do agree it is in a very vulnerable spot sitting up high like that. Running a body all the time is an absolute necessity. Right now I am only running a single pack. If it runs well with one, I'll relocate the black box to the unused battery tray on the left side.

Advice is much appreciated; this is a work in process so things that you guys can point out that look out of place are very helpful. :cheers:


Now for this mornings run. It lasted all of 2 minutes. :flaming: The first 1.5 minutes were great!! The throttle response is instantaneous. And then something weird happened. When off the throttle the truck acted like it had full brakes on instead of coasting. I thought that I might have programmed too much drag brake in the ESC, but upon closer inspection the front cover for the motor had separated from the can!! The only thing holding the motor in was the pinion, which was too large to pass through the motor mount. I'm glad I caught it in time before it chewed up my drive train. I'm going to make a clamp that spans the length of the motor, which should keep this from happening again.

Pic of the loose front cover. Maybe a couple set screws will keep it in place?

Can you move the box closer to the front? Or are the wires not long enough? I have to agree with the box taking a hit and your creation being carried to the pit table. Damn it looks pretty fly. I have a buddy making a brushless set up for an MBX5 as well as a X1CRT. Ideas are cool. Cool to see bothnitro and brushless versions running side by side?
 
what about on the opposite side where you would run the second battery?

Would it work if you put the esc next to the reciever.

I think I may try that. Initially, I was against mounting the UBEC close to the ESC for fear of interference. The UBEC is known to sometimes make the ESC not operate smoothly. But I haven't tried for myself to see if it was true in this application. I can mount the UBEC towards the front underneath the battery strap, and the ESC box in the rear on top of the strap. The motor wires might be just long enough to reach. If not it is a simple task to extend them an inch or two. I'll also need to make a new battery strap to accomodate the width of the esc box.
