Default Baja 5b Monster truck project.

6/12/20

So I've been searching for a decent 1/5th scale monster truck online and there hasn't really been anything that has interested me. Problem with most rcs at this size is they just dont have the ground clearance effectively making them buggies with larger wheels and I've decided I wanted to try and do something different. Something no one has tried before. Now I did already have a Baja 5b, if you guys follow the 5th scale obsession group on Facebook you probably have already seen it a few times as I'm fairly active there but if you haven't here's the before photo







now I've done plenty of research and pretty much tried to cover all angles before committing money towards an upgrade like this. I wanted to make SURE I wasn't wasting money and time into another failed project so I've gotten in touch with the people at KingMotorsRC "I know its taboo to say that name", Largescalerc, and OBR whom was able to give me advice on what parts to get such as steering and suspension reinforcement. So I present to you my "unfinished" project which I shall nickname it "The Crushinator"







I think it has come out absolutely fantastic and I dont have a single complaint about it other then the fact that its 2wd drive but eh nothing you can really do about that.

I'm seriously trying to get a hold of the people who make these things to sell a kit like this. It's honestly the best 5th scale rc I have ever seen.

I've painted all up the body and did some more suspension tuning after testing. Found out that the rear shocks stock shock oil couldn't take the extra weight for some reason and started leaking so I put 35 weight Losi shock oil inside and has held up greatly. One thing I can say about these wheels is that the compound might be a bit too soft. I noticed after a few street passes that there are very small amounts of wear in the shape of cracks on the sides of the treads but nothing to be too concerned about, just keep it off the street and sharp rocks is all.







Lastly the stock steering setup just doesn't cut it. My best steering angle is probably 25 degrees. I've ordered a symmetrical steering setup and a 70kg servo. I'm not sure servos go any higher so I'm HOPING it'll work. Being that the Raminator has 2 55kg servos and it can steer those massive tires I have high Hope's this will work.

Installed extended wheel hubs added about an inch per side to extend the wheelbase just a little bit. Felt like the wheels were a bit close to the body so this helped it.







Wheelbase is now 22"w and 30"L from end to end also found a way to permanently mount the rear wing. It kinda clips into the plastic in the back with the help of 2 zip ties.







6/23/20

Decided to upgrade the top end of my 26cc engine, needed a bit more torque and didnt want to gear it down. Painted to match the body









Piston size difference =]







Went with the DDM Dominator 5t pipe and boy she is a beaut, discounted to $99 cant be beat







Break in temp video



Small braaap for the homies



unfortunately the chassis wouldn't fit so I had to loose a bar. Not a big deal to be honest.











6/24/20

Sym-Steer kit came in, getting excited now







looks great installed but the on off switch is in a REALLY bad place. Might just have to deal with it







also I noticed the steering kit was installed wrong in the last pic, heres a little tip for you. If you purchase this kit, use a micrometer to make both sides the same length. You can use a t square to make sure its straight.

A bit of a bonus photo. Here's a pic of what it looks like as a buggy still.


Just so we know what we are dealing with here I decided to use a Savage XL for scale.

I'll admit, it looks great with the big tires and cage!. I had an HPI 5T 13 years ago or so and I could never go back to a 2wd 1/5th scale. I'm blown away by my mosty stock KM X2. I do like the concept of what you're going after, who knows, maybe Rovan could provide a kit if there is enough interest. Rovan already sells that wonky Baja Max 5T and it seems to be popular so I'd imagine more options would be great for the 1/5th side of the hobby.

First full fledged test today and all I have to say is my god, this thing really ripped even with a 26cc engine and a bad exhaust.


Tires are holding up nicely despite being so soft. They really are meant for the dirt and grass so that's where it will be staying. Seems to have issues with the road and rocks so if you get these same tires make sure to steer clear of it.

Heres a video of her shredding around a baseball field Video URL

Also a bit of a curb test to see what I can safely go over Video URL




there is a 6k clutch in there right now that's still good but I have a feeling it's not gonna last much longer. Went and picked up an 8k clutch today but I'm wondering how a 10k would fare.
