Homemade Brushless Baja 5B style Buggy
 

Ok guy's i built this about 5 months ago.

It's based on a Muggy with a stretched chassis to meet 1/5th scale length, I picked up a Muggy as a roller and the idea started from there.

ESC = Hobbywing 150amp
Motor = CC 1717
lipo's = 3s 5000mah in series

And this is where it all started......

Looks very nice - more pics please - show us how you did it. :yes:

:great:

That thing is wicked! Looks like 2wd from the photos, why not 4wd? I know the Baja is only 2wd but with the muggy platform why not? Nonetheless a great job.

Definitly very cool, nice job. And yes, show us more of it!

Thanks guy's yes many more photo's and video's to come. Definantly 4wd guy's.....

Here is the front of the chassis

Starting to take some shape at this stage

The muggy link is as you can see very thin and easy to bend so i made my own link, much bigger.

The rear tower was very short so i got one that straightens the shocks out

HHHhhhmmmmm bearings much better

much bigger than my truggy

Wow,very nice build,is it just 2wd? Why not keep the muggys 4wd?

Looks like its 4WD to me. You can see the rear drive shaft and the extended front drive shaft.

Guess i missed it, now it's even cooler!

Very cool, I like the stance of it and the fab work is awesome.

Ok motor fitted up

The front alloy prop shaft did't last long so a 12mm steel one now sits in it's place.

Got a 33kg servo that can handle up to a 3s lipo from HK for about $80 delivered.

Lipo's brackets done.

I mounted the ESC on the underside of the roof, it's out of the way and the wires are much neater coming down to meet the battery's and motor

I'm curious, how did your first driveshaft fail? (Mine has held up well)

That's not a bad idea! :)

This is what RC-Monster is about, that is an awesome build.

How much does it weigh rtr?

This thing is definitely awesome. I have had great luck with those Turnigy HV Titanium servos so far. I run the 2S version, HV767.

I think it might have had a slight bend in it and with the torque and speed of the 1717 it just twisted.

It weighs 7kg with everything in it

15.4lbs... not bad, my Savage conversion was about a pound heavier.

I would rather have one like yours than a real baja, much cooler, lighter, BL, and 4wd!

Thanks mate it is pretty awesome, I got a lot satisfaction in building it and it's great feeling when your driving it knowing you built it.

Wow man!! That thing is awesome!!:yes: Why haven't you come to Rc-Monster sooner?

Great build I love it!:love:

Building it yourself tends to have that effect, gotta love that feeling. My rebuilds and minor customization just isn't cutting it for me right now. I think it's time for me too build my own monster truck based 5b buggy, I've been admiring everyone else's long enough. Although I do still have the 5t body from my failed stretch chassis Revo, descisions descisions.

+1

IMO your Baja looks much more cooler than a real one! Great job! You might want to replace the stock shock for a aluminium one, Losi (and other companys) have got nice anodized shocksfor LST/muggys.

What shock tower is that? And I'm guessing the bulkheads are losi muggy?

Very nice work.

very nice indeed. I have always wanted to do a 5th scale conversion using a truggy as a base...been thinking about it for 3 yrs... I may have to rekindle the idea.

Thanks mate, I'm not sure why but i'm here now.....lol

You should do one made, it's very rewarding. I think i have seen your stretched revo on youtube in a car park going over a small jump, it looked like the counter lever suspension setup isn't up the size of 5th scale.

Thanks mate, yes i am going to get aluminium diff cases, shocks and the front tower as well.

Yeah the bulkheads are muggy and i think from memory the rear tower is a LST

Do it man do it, you will love it more than any other RC you have ever had.

Great looking build... Love the use of the muggy platform combined with the cage and wing, very sharp looking! Should be a beast :intello:

Yea I need to do another build. That revo wasn't mine, never did get any vids of it. But the results were very similar. Even with the stiffest springs and sway bars it couldn't support or control its weight very well. And it was under 14lbs rtr. Needed to be a little wider too, and the 5t body kinda limited that. Think I'll see if my LHS will trade me the brand new 5t body for a 5b body set and cage, then find me a roller to build. Thanks for sharing your build dude!

Just for some fun i thought i would put some brake lights on the under side of the wing.

This is the first run out the front of my house, just a quick test to see if everything is working.

Love the build, great looking buggy. :smile:

Looked at a few of your vids - nice - may want to tape those front tires, though!

Questions: What top-speed are you geared for? Have you done much suspension tuning to dial in the handling?

-brian

Yeah i know it's crazy, i put very thick oil in the centre diff too.

i never geared it for any sort of speed i just went concervative to see how all the temps were and i haven't felt the need to change anything yet. it's got the muggy centre diff and a 15 tooth pinion.

No suspension tuning yet but i'm looking at getting some raven dual rate springs, not sure what oil yet. the buggy wieghs 6kg rtr but i'm thinking of fitting in one 6s lipo along with the other 2 3s lipo's and run it parallel with the 3s lipo's for longer run times this would bring the wieght up to around the 7kg mark.

Well since a stock LST is around 5kgs and uses 30wt oil, I'd suggest 40 or 45wt to start with.

40wt oil in an LST shock is very thick. I was running 30-35wt oil in my 19lb buggy with the RC-Raven springs and it was plenty. More recently I've modded my pistons and will try out some weights, but you can read about that elsewhere. :yes:

WOW.....i checked out your build, very nice. yeah i'll start with 30 and see how it goes.
