Anyone converted a mugen mrx4 or mrx5?
 

I am looking for a conversion kit or motor mount for this car. Anyone can help? Thxs!

I've searched and searched, they all seem to be home made conversions.

Why not try a brushless ready serpent?

I m running all mugen cars:) from buggy to truggy.

It's not English:(

his link is for a motonica, not a mugen.

What happened to all your Jammin stuff!?

You ask and you shall receive...Although it's a MRX-3...same basic set up. It's a Revo motor mount

I had a machinist press a fitting inside the hub which in turn eliminated the one way bearing and allows me reverse and motor bakes. Eventually I am going to eliminate the AL bottom battery brace and replace it with carbon fiber...

I am running a 1800kv on 6s and it flies...haven't quite dialed in the esc for a little drag brake, motor brakes yet but working on it. The first time I took it out I almost totaled the car..missed a concrete light stanchion by inches doing 50mph+ This is my first true on road car as it has a learning curve as I only have been running in the dirt

I have 3 Mugens as well, love them all.

MBX5T Truggy
MBX5 Buggy converted to on road
MRX-3 Electric conversion

Wow! How do u do it? Where can I buy the motor mount?

I still hv my nexx8 n scrt10. Trying mugen Eco n their truggy:)

I bought the motor mount here at RCM. The motor mount was a pita to mount as drilling and securing the mount is tricky as there is not a lot of room for nylock nuts on top of the mount due to the motor clearance

Do I need a special tool to fit the motor mount? Is mrx3 same as mrx5? Thxs!

No special tools...just patience, tape measure and a drill. Not sure if the 3 is the same as the 5. Although the basic cars are the same

So it's rcm Revo motor mount? Btw how many mins can you run on a 1/8 on road?

Yes, its the RCM Revo mount...http://www.rc-monster.com/proddetail...&cat=33...Well, so far w/the 2 battery set up, I can get 15-20 minutes run time...sometimes more depending where I am running. In the smaller parking lot 20minutes+, in the larger one where more wide open throttle is required a little less

I was told it's very expensive to run this 1/8 on road Ep. No traction as it need caster oil on the ground, need truing of the tires?

Hv u tried 4s with higher kv motor?

Hv anyone tried this?

No I have not tried that, but, it just may work w/the Mugen set up. I had a machinist who works for my boss do a mod for me on the 2 speed adapter and I already had the motor mount

Do u need caster oil to get traction?

No, just be easy on throttle. It is easy to spin out though

anyone converted a mrx2? someone gave me 2 cars.

I have one of these cars and my buddy has one also we drag race them, the cars drive fine but you really need to gear up and run atleast a 5cell cause the nitro car is really close in performance. i have done a few mods like remove the oneway bearings from the front wheels so that all wheels brake but it's one of my best conversions so i'd say well worth the time.

Any pix? Btw is it better with all wheel brake?

Removing the oneway bearings from the front wheels? Any more info on this.

this was some rush work when i first built the cars but now i have cnc mill access the motor mount will be replaced this week for the up and coming season. the other car is a XR80 he's now running 8s with mech brake . i have a small crack from a collision that happend last year in my front bulk so... since i don't have my bearings done yet i could post the process i use here.

Pls post pics when u hv it done. Wat motor mount u used?

Also on the brakes im not really sure how other people feel about the current setup for these cars, i watched a few races with these puppy's and it seems they use the brakes to help rotate the car in the corners and i have no need for this feature so i locked the fronts to help control braking from higher speeds. so it may not be for everyone but it sure tames the car to be driven like a normal car. just my few marbles

it's really hard to say, it all hinges on the motor you use we chose 2200kv's due to the deep gearing and speed we wanted the speedpasion mount will not work with the 2200kv so i chose to make my own mount. the revo mount from rc-monster looks good for the 2650 also and would fit a few others i just was in a rush to have what i wanted and made a few crude dude mounts if you use mech brakes you will find things a even tighter fit

Ok then...how did you accomplish this. With my mrx-4, if I tap the bakes just a little to much, I am in trouble

The bearing size is 10x6x12mm for these cars i looked for a while for a bushing this size with no luck and then i was forced to make them but now i have options so tomorrow ill have some bushings made. I will be thread locking the bushings then drilling then tapping and ending with a grub to lock the wheels.

I recommend you protect the lipos with a aluminum plate or a hard plastic ....... if you have a bad crash is possible have a disaster :p

With this kind of car it's like riding a motorcycle it's risky,dangerous, but i fully understand what i'm doin and i wish lipo were not so dangerous but no pain no gain !

What gearing you guys do? Rc monster has a 46 spur for gt cars. I will use either a 2250kv motor or 2700kv motor. Wat pinion u guys recommend?

What bearings are these?

Is one of those motors in the last pic much fatter than the other or is it just my eyes playing tricks on me?????

Thanks for that pics guys. This is going to help immensely with my Serpent 960 conversion I think I am going to do the batteries the same way as you did magman. I hope I can get some 4-5mm thick carbon fiber plate and make like a wide pan chassis so that the batteries can fit on the sides of the chassis. I think that would be the neatest and easiest solution (posibly the lightest as well). Do you guys think that 5mm thick carbon fiber would be ok for the main chassis (bare in mind it will be a lot wider and hold the lipos on the sides)???? Once again thanks the pictures. Great help.

Rcm make a 1 speed spur for 6mm shaft. I am getting that for my mrx2

Magman is running a CC1512 1800kv. The shorter can size in a small space does play tricks on your eyes a bit.

Link please!!!!!!:happy:

Also If and I mean If I decide to keep it as a two speed what are the gears I need to get. I an totally a noob when it comes to this kind of two speed setup. I think I will get one either way just to try and see. I might like the two speed but I just like the simplicity of running just one pinion and one spur gear. Less moving parts the more I like it.

I am going to make up a mount that I think will even house a 1518 (from what I can measure it should). I am not sure if I'll use the 1518 on it but if I do it will have to be on 8S. That will mean a plane ESC (to keep the costs down) and will need to run mech. brakes (I think I have even this figured out).

What is troubling me now is the absence of front braking. Actually scares the crap out of me. I really want to run front brakes but that means locking up the font axle. How would this make the car handle? I wont be racing it as I just want something fast and fun but don't want something that corners like a drunk pig. Wish that there was a front diff option.

OK, that's what I was thinking. The next motor in size up (diameter wise) is the 1717 and that would be just plain crazy in one of these things.
