1/6 truck build

[Mechanicalbob]

Well I think this is the right place. As it is not going to be a crawler or a true scale truck. It is going to be close to a FG Bigfoot monster truck. I have the body on order. Here is some pictures of the parts have to start with:

The Tires are Proline Moad 40 Series. I have a set of rims picked out just waiting.

The aluminum I am using is 6061

The overall width is going to be about 20 inches.

The wheel base (center to center) is going to be 18 inches

The power is going to be a Wacker engine not to sure of what one yet I have a few to choose from. The one in the picture is a 32cc Stihl, I am lookig for a Stihl 40cc bruscutter mill with electric start. The tranny is from a T-Maxx truck.

The diffs in the truck are going to be from the Maxx truck as well. Most of the center tube for the chassis will be cutout, I may put some side plates for shock mounts and other things or go the Revo route for suspention.

dam this is going to be the colest

nitro?!?!?!?!?!?!

Not this one sorry. I am using gassers, if you can not tell by the spark plug wire and the magnito in the pictures, nitro doesnt use any of those. I have converted Wacker engines to run on Nitro before but the dont last long.

how well will the maxx trans hold up to a weed eater engine?

I have that exact same engine!

I had kinda the same Idea but, I invisioned Lawnmower tires and 1/2" wobble driveshafts.

I had this engine on another project back in the day.

With the centrifical clutch, it applyed power nice and smooth...

However.... I might be wrong but....you are going to want more gear reduction for crawling and also I wouldn't use anything less then Revo shafts.

If this is an all out basher that you still wanna get some speed out of then I'm wrong.

now for the maxx diffs to handle that kind of power, you are going to want an aluminum diff case, and you need to drill out the holes in the ring gear to accept a larger screw. Also tap the spool.

With two 1.5HP electric motors I have sheerd the 4 bolts that hold the ring gear to the spool with the first wood. The 1.5mm screws will not handle the power.

I have yet to break the 2.5mm screws I have now.

Sweet project man!!!

The Maxx tranny's hold up very well. Take a stock set up with a nitro engine, the engine spins at abut 30000 rpm at WOT. a wacker is at about 7000 WOT. With a 20tCB and 82tSpur gear(about 4.1:1). the tranny input spins at about 7317. With a direct drive from the wacker engine it is 7 grand fairly close to original, with a few mods I can get the R's up a bit more. I have built a few like this before and the tranny holds up with out a glitch. The best part is get a bigtruck with 4X4 and reverse too. I just have to work on the brakes.

Also think you should have left the cover intact over the magneto. Its not just a cover, that is the ductwork for the flywheel to cool the engine.

I wrapped aluminum tubing around the head in the cooling fins and planned on running a radiator with a fan and some sort of pump....

Aircooled 2 cycles don't like to get too hot...

[Mechanicalbob]

whats the demesions of that sq tubing?

It is 5" across and 2" tall, 26" long with 1/8" wall.

Do you have any plans laid out?

I have some plans laid out, I will post more info and pictures when I get a little more done with it.
