Default Pro mod Bronco buggy chassis

I just started a new tube chassis to replace the one from my previous build (which is in the 2.2 forum if you've seen it) This one is alot smaller so it's using shortened door, fender panels. More just a buggy with a Bronco grill. I'm just gonna be brief for right now.
  • Gonna try to do an interior
  • I like some rock racing so I'm seeing how wide a summit tranny is too use as a t case (I only got about an inch maybe more so idk how possible it is) I haven't got any repies on the traxxas forum for dimesnsions yet
  • Using 2-56 nuts(little bigger than 2mm) for body panel/crap mounting (I got a crap load of them from someone so these will be alot nicer than big 3mm screws)
What I got done since I started it yesterday morning It's brazing up a bit dirty though. Don't mind the front end, I'm deciding what to do on a bumper

I need to see how tall it is if you laid it on it's side (the width)
And how do you like the gear change? Does it allow you to change from a medium high speed to a average crawl ratio or better?

I really like the gearing change , It will do a slow crawl to pulling wheelies in 2nd gear,
FRom outside of the spur gear to the outside the motor its 3.5 in widelike in this picture

the gear box itself is about 2.25 in. wide

Tits...... I only got about an inch to spare. Idk maybe I could just mount it up front where the engine would be but then I still need a T case and it's gonna be heavy.

ahhh spur is not installed in that pic sorry
but you get what i mean right?

the trans is quite big my frame rails are 2.875 wide and it hangs out over them a bit but its worth it if you can squeeze it in there.

Pretty skinny chassis at 5.25in, wheels at 9in

Got a little more done but I haven't been workin on it 10 hours a day since Thurs. lol. But I started cuttin up the body panels and I've been making panels out of this .030 aluminium from homedepot which I've been cutting on a wood cutting band saw with a metal cutting blade lol, sucks but works ok for this light stuff. I made the seats, roof and 2 floor panels out of it and the firewall out k&s sheet stainless. I'm gonna wrap the seats in something but i dont know what yet.
  • I ordered a hpi gear reduction and I'm gonna see how it will fit and
  • I'm probobly make a simple t case out of 2 pinion gears.
  • I'm gonna braze up the sub frame which will drop about 3/4in
  • I'm gonna be hangin out my grandfather next week so I might be able to get the frame sandblasted if I finish it in time (he works for a relative at a machine shop so I got see what goodies they got there)
Yea, I eat at my work bench alot



This stuff is gonna bolt down, eventually






Heres compared to the old chassis


Seeing what I'm gonna do with suspension travel I'v got no idea right now

Didn't get much tube work done but I've been messing with someother stuff lately.

tight space. Esc will probobly go up on the firewall though.


3/4in to the table


messing with some styrene, I need to get some green putty from the local hobby store. And other stuff, can't remeber wat


micro t batteries (1/3A) (6v) brass tube for the space filler. Not finished, need to find the volt meter to check it. (My father always takes my tools) Looks nasty with all the shoo goo and bad solders, Could not get the factory spot solders hot enough to detach so I ripped them off and grinded the poles with the dremel. Probobly a little bit bigger than scale. If it holds a charge I'd like to use it as a receiver battery. For the big batteries, I'm gonna use 2/3a (6) in the nunchuck style which will hide under the rock sliders/side skids.

Found the volt meter. (I had it, not my dad lol) And I was getting 4.5v which I wasn't expecting for overcharged batteries which had been sitting for like a year+. So I popped it in the chrager on 1amp then remembered it's not regular 2/3a receiver batteries. It got super hot (smell of burnt shoo goo was in the air) and now I was getting 2.7v, great . Forgot I had a micro t wall charger so I converted that to tamiya plugs and now I can use the adptors for this and my dx6 and not charge on 1amp I'm pretty sure my dx6 battery was screwed along time ago though. Right now I'm letting it cool and I'm gonna try the microt charger.

Very nice tube work. Cool rig. Waffles need some peanut butter and then a bigger glass of milk.

Lol, penut butter.

Brazed some nuts on. Very very hard with 2mm size nuts (2-56)
But what I do is have a surface to lay the nut on which is the only thing that seems like would work.






Motor mount: just like full size custom mounts. Dirty but strong. I'll do the other side once I figure out how low it can drop/angle. I'm running out of Silv and my 15' of brakeline "magicaly dissapeared", so I got to get a little more for the sub frame. Then off to the sand blaster so it dosn't look like ass.

Got a little more done. I also got more brazing silv in the the mail so I can finish up the chassis. I did some stuff with my electronics

LED light bar


Pico switch made from a servo board (if u didnt see my thread for it)


ESC mounts








My antenna on my dx6 was broken so I shortened it


re sufacing the screen which had eaten spots from CA activator (previous owner lol)




I was swaping lockers from a used axle I got and found this which was cool


Some mock up pics. It looks cooler in person which is weird, no joke.
