Kyosho rampage pro - no moa!

[fxman]

So i'm guessing the ride is smoother that what people have been anticipating? My RTR kit is scheduled to arrive soon, getting excited!

I don't know what you plan to run in this one. I run brushless on 3s and it is a beast. 2WD is hard to control anyways. I'll need a lot of space to actually pull the trigger all the way. The ride itself is smooth though, shocks are great. The spare tires in the back let the body bounce slowly and keep the rear axle planted.

Hey, no sweat - I didn't mean to sound like a dick and I did not want to offend you. Sorry for that. Seriously. Has to be said sometimes also.

It was rather meant as a suggestion to start your own thread, as you are doing something very similar - and I am eager to see how you approach this! It just gets confusing when you browse through this and get the different trucks mixed up, okay?

All good man, and sorry also for getting a bit bent out of shape. 34 years in RC for me has been a collaborative effort and I love to see/inhale others efforts as well as sharing my own explorations.


My intention in this thread was simply to show my take on it, using your build as inspiration, but also hopefully to find a home for the different ideas a few of us (well, I guess you and me at this stage) have found to work.


My build is pretty much done now. The inner cage has been a bit of a pain but have managed to figure out a way to hold it solid. Wheelbase ended up being out by about 5mm (if that), but not really noticable. Can't fix it though coz of the shackle locations on the RGT axle. It's a real balancing game with upper and lower link lengths here!


I've got my eyes on another Pro to hit up with a similar treatment, that one will probably get some chassis mods to fit the drivetrain a la that Insta post.

My take would be that, with the modifications, the Kyosho behaves like a rabid Baja Rey.


Meaning, it handles like a 2WD live-rear-axle truck would - in every respect. Like the Baja Rey, it's kinda tricky to control (that's why I have gyro Rx units in both my Rampage and BR) under power but that's also half (most?) of the fun.



From reviews i've seen/read, the RTR isn't too planted due to a lack of weight in the back...if you're talking about the new RTR version then that will be a different beast altogether.

All the Pro kits were sold out so I settled with the older rtr version and purchased bearings, steering and stabilizer upgrades.

Il try to figure out a rollcage setup for the rear. I have a few ideas but nothing that I cant validate until I get my hands on the truck.

From my understanding the new RTR version is an in between version to the pro kit. All it has upgraded on it is the actual cage in the back. Nothing else...

I just got a spare roll cage in (23$ - yeah!) - it looks exactly like the one on my Pro version, but came with a single black spare wheel instead of the two chrome ones. Also, the wheel is a lot heavier. From pics I have seen, it should bolt right into the old chassis (there are two holes for it) and mount to the body posts - can't see any other difference.

Have you tried Kyosho directly? I got mine on ebay - compared to other roll cages, this is a steal.

The whole body/cage setup is a strange one though, as nothing is solidly mounted whatsoever, allowing all sorts of flex over bumpy terrain.
But it works, somehow. You'd think the truck would wallow around and be kinda vague under direction but no, it works perfectly.
So good in fact that last night I bought another Pro (assembled, painted, Castle S3 power setup, never run) with a spare new body. I *might* run this one as MOA as a comparison to my build...but probably not. It'll be butchered :mrgreen:

Summer was too busy with work and I had this Kyosho Outlaw Rampage pro kit sitting on the shelf for a while. Well, I finally opened the box and found out, it’s 70% assembled. I like kits and was missing the build challenge, so I took the ugly Motor on axle (moa) off to at least look at the gears... and then it hit me:
The rear axle is much narrower than a short course truck or a Yeti. In fact, it’s almost scx10 width. So, 15min later I had a rough mock-up and what I will be dealing with the next weeks. Rampage pro solid axle truck done right:

I need to dial in the upper link length and decide with which drive train I go, but I LOVE that body and stance - and that it is more tenth scale and not ar60 width.

More to follow

I will follow you if you answer my question as follows: how wide are the rear a-arm mounts on the original MOA axle?

It's really mind-blowing!

Not sure what you mean. The MOA axle has no "A"-arms - it's solid axle. Do you mean the trailing arms that hold the axle in place? Here is a pic of it.
A= 165 mm (6.5")
B= 140 mm (5")

Yes I meant the trailing arms, thank you very much

Finally getting around to breaking the seal on mine, and will be using your build as a guide. What length drive shaft did you wind up using? How's the fit of the 10.2 kit trans in there? I'm leaning towards that route, but wondering if a Yeti trans would give some more wiggle room.

You will like it I used a Yunfac shaft I had laying around. The way I installed the trans I needed a shaft length for a distance of 95mm minimum and 105mm extended - I think mine came off of a Gmade Sawback.

I originally had a yeti trans in mind too but don't remember why I didn't follow through with it. I think it was too big for the available space.

Not sure if I posted this one? You can kind of see how the scx10 II kit trans is hanging down from the hole I cut into the chassis:

Thanks for the info! I did see the bracket earlier. I've been sketching up a couple of designs that are more protective, kind of like a skid plate/trans mount, that will align it in the same spot.

How did you wind up mounting the battery/what size are you using? (EDIT: Nevermind, I just found it. Must've skipped right by it before.)

This is awesome. I finally received my pro kit. Now I'll have to decide if I want to do this!

The good thing is: if you screw it up, the chassis is dirt cheap - LOL
If you can't find one, I send you my spare one. Having a back up gave me confidence. I need to take mine out again and try to do a video.

The more I look into the "how" of doing this conversion, the more I can see that it would be fairly simple, and easy to improve on what's already been shown to work. So I guess the real decision isn't if you want to do this, it's when will you start! "thumbsup"

I'm going to drive it built stock first.... and then maybe tackle this mod.

I need a refresher on what to get for this truck. I remember people mentioning the Associated Spur gear and what not. I ordered this back in November last year, and I just got it this past week. It's been backordered forever at Tower.

 

[turbodan13]

What's the overall thought on powering this thing? Brushless SCT system on 2s, or a peppy brushed set up on 3s? I know the stock MOA trans isn't really intended for 3s/goofy power, but I'm looking primarily at the axle conversion power needs.

 

[fxman]

I run 3s with a brushless castle system
