The set I'm working on now will be complete sealed and have a rim that is 1.5" wider than the rims I used previously. It will float

Okay sweet! Big fan of this build.

Looking forward to seeing what you come up with. These big trucks are too much fun!

The inner tube idea wasn't going to work. To much weight and not enough displacement.

I got in a set of Ofna Pirate rims because they're 4" wide, almost full offset like my truggy wheels and 17mm. How perfect right!? Wrong. I went to mount the Jumbo Kong on there and it turns out the Ofna rim is smaller than the 3.2" maxx size rim. So the tire would never fit on there correctly.

Took me a while to come up with a solution and it's still not perfected but it's forward progress. I had a set of rims that come with the jumbo kongs and these fit well enough that they hold air without even being glued. So I know I wanted the beads from these rims. Got the calipers out and did some measuring and came up with a plan.

Cut the bead rings off the rims that come with Kongs usin a band saw then cleaned up with a belt sander. The front is going to need a lot of clean up work with the dremel since some of the center cut off with it. Should be ok though. I'll be using this on the backside of the modded rim just in case it doesn't look as nice.



Setup the router to take the lip off the edge of the rim and leave just a tad bit of material to make the fit nice.



Now the rim has a new bead that I know holds air



Backside of the rim will be the same using the front of the cut up rim, it's just going to take some work cleaning up that bead. I'll glue these rings on with CA then I'll run a bead of silicone around the inside just to make sure it's sealed up.

Very Creative, Good Job !

Wow! Really looks good in the water! I see no string attached this time....

How is traction and climbing with the air? It seems like that would be too stiff... I know u can release some pressure as well.

[NickRummy]

I had the rope on for the first time it went into the water but I seen how stable it was and knew the rope wasn't needed.

As for the tires with the pressure in them. They are horrible on land filled up Very bouncy and you only have the center of them contacting the ground. I did actually have a problem with them blowing off the bead of the rim. I think the truck is just too fast and weighs to much. Since this wheel combo works so well I'm just going to go ahead and glue the tires to these rims. I actually like the look of these wider tires and wheels. With the tires glued and low pressure in them they should get great traction.

Awesome Dude ! The build is getting better and better .

[NickRummy]

Got some video together from the last week or so. I got the 2 speed hooked up in the 3905 trans I put in and used the wide range gear set to get some nice gear reduction in 1st gear. It's definitely fun to use and has TONS of power. Last weak link that needs work are the axles....... They just wouldn't put up with any more abuse.

Almost forgot I had these pics for a good size reference.

Whats the game plan for the axles ???

I'm still researching and trying to decide what 1/5 scale sized truck I want to build,but I know one of these axles will help determin what I build. Could help you also ?

Send an email to nick@rummyrc.com. I can share it with you but not publicly right now.

Those axles you have listed from RC4WD are all way to small. The only one that might work is the Twin Force axle. That will take some punishment. I would have used them on my truck but they are only around 12" hex to hex. The X-factor axles I'm using are 14" hex to hex and the rims are full offset.

Read thru this and have decided that I need something like this!!!!

I have 4 bodies right now, navigator, avalance, hummer h2 and another that I just cannot think of. All are 1/6 scale, and have interiors!

So I ma thinking that I will need to make my own axles... Something sturdy (steel) that can use some existing parts that I have.

I just sold two of the avalanche bodies I had. They look real good on this truck's chassis

Was it this body?



Not a big chevy fan, but I do have a huge navigator body...

[NickRummy]

Yup that was the one. I had an H3 and Grand Cherokee body too.

Check out this building using one of those avalanche bodies. He actually locked out maxx axles to make them solid axles then 4 linked them to a chassis.

Thanks for the link! Looks good with the "pile o rocks fallin down a hill" body on it...

I think I will do something with the navigator body, it is huge!
