Km001 roller build

[Mick Boomer]

So I just got a Km001 baja roller brand new for $360 shipped. Ive always been a strait up hpi guy (and still am). Over the years ive accumulated motors ive never ran or ran very little. Same with the electronics accumulated over time.

Overall its not bad at all. Obviously not hpi quality but not bad. If I was going to have to buy everything I would go the hpi route but if you have electronics, engines, and pipes hell why not. Especially if you already have 3 hpi bajas.

Im keeping it mostly stock. Build parts on hand; shims for steering posts, alloy engine mounts, Bizeta exhaust pipe, lipo battery, hitec 7955 throttle servo, stock hv steering servo that it came with, ESP g320, rovan alloy clutch carrier, vertigo clutch bell, hostile 18/56 pinion spur and gt3b radio.

Time to strip it down to check everything.

Congratulations on your new rig,

Did a mockup before I tear it down. I like it a lot!

just sommat to bear in mind for the future mick,
the tank and battery box are a slightly different size on the km,
not by much, if i remember right the km has a slightly shorter tank and longer battery box, or could be the other way round ,
plus if the steering servo is km then its a sllightly different size to hpi/savox etc,
so the servo holder is a different size, but the hpi one screws straight into the battery box so ya can change servos

It came with the steering hardware for the km steering servo for the rx box. Also the servo seems pretty dang strong and quiet too.

But yes if you want to use hpi stock style servo you will need this part

What are your plans with it, looks like a good start

Tbh Ive never seen or had a rovan or km platform and I have everything to complete the build. Having 3 hpi bajas I just wanted something to build. Suppose I can compare it in my experiences with hpi in the end. Just bored really and wanting something to build lol. A beater lol

Alloy mounts 18/56 gears. Pulled transmission apart. It had stinky gear oil in diff. Cleaned and used 20,000 diff fluid.
Diff looks ugly and had some metal shavings in it. But its smooth now.

 

[MCD dood]

MMM you definitely don't want metal shavings in the diff, good thing that you check it out

VERY NICE build so far. I like reusing RC parts as much as i can.

I understand the need for the screen. My question is what is the best bonding agent for the Orange Arrow as i would like to do it to my new to me motor.

Looking good brotha. I just got the same rig for the same reason lol I think Im going to build mine for my wife to beat up. My kit didn’t even come with the steering linkage off the servo

You can use just about whatever you want. I've used epoxy and various rtv, and shoe goo. Liked the quick set epoxy the best, but you gotta make sure it's where tou want it.

 

[Mick Boomer]

I use clear rtv silicone

 

[Mick Boomer]

She is done. Im very happy with this km platform. I do recommend one. A beginner might get stumbled on a few things but if you already have experience with hpi bajas, pick one of these up and save 400$.

Came out wicked. I’m going back together with mine now too
