RC Truck Racing Mods

[TOA57Y_27]

Hey guys

I'm just wondering. Is there anyone here who has used a tamiya tractor truck for RC Truck Racing? The main part i'm wondering about is getting a taller diff ratio to increase the top speed of the truck and make use of the three speed box. I did have the thought of using the 4:1 gear reductions, but putting them in backwards. Effectively making it have a 1:4 increase in ratio which in turn would force you to use 1st gear to race. Anyone else got any other ideas?

I dont think the Tamiya trucks are that good driving fast.
You'r going to tip in corners at high speed.

Otherwise you coud put in a Mamba Max 6900 or 7700kv to get awesome speed.

Also, the stock tires have some good grip, so you would probably need to get some drifting tires of some sort or you will tip like Pete said.

Thanks guys

It's only in the development phase atm. It will just be stock trucks to start with. Once numbers build up, then we'll look at an open class. We would be going for faster motors but also want to make use of the three speed box by an increased ratio somewhere after the gearbox. But atm, it's stock so we'll run with that and see how it goes.

You could just try a bigger pinion. In the real world the racing rigs are limited to 100MPH top speed

I built this a while ago. It's heaps of fun to drive. Tamiya car chassis, plastic tires, day cab Aeromax. and lots of lights under it. This is what I go DRIFTING with.:Tamiya1:

what chassis is that on?

i put a 19 turn drift motor in my truck at first and it was too unstable. it tipped over in first gear at a quarter throttle.

more speed?
not for track racing
my king hauler is stock and flips in the turns in 3rd
drag racing is different cause its straight only
want more speed with no mods? swap the motor to brushless
get ready to replace gears
lol
the truck is basically too unstable
it's very top heavy
you basically would need to lower the center of gravity
also you could add wider wheels or wheel extensions pushing the rears out adding a bit of stability
but if you do that, just do like the max above a have your body on a pan car or something

All practicality obviously aside, would or might a Fiegao 580L fit in a Hauler with a gear reduction unit?

I am planning a build so I don't know the set up yet. A thought I had was flipping the trans. This would put the motor witch is heavier at the bottom (I have built the ford high lift with a crawler motor). Then keep every thing as low as possible. Do a cab and a half sleeper to make room to spread things out. Stick it in the frame. Then use an aluminum rear axle or two to add more weight lower to keep the feet planted. The gear reduction is a great idea. This will definitely need some mods from what I have read but his build seems like a really good idea. Best of luck.

This guy does some really sweet custom stuff. He made one of these as well.

yeah i was watching some you tube of a guy drifting a real scania or mann i was thinking of building a globeliner drifter myself i plan on using all stock frame and tranny with a drift motor and using drift tires on truck rims

[RCMAN2112]

i was you tubing the other day and saw a vid of a guy drifting a real man or scania i am thinking of building a drift globeliner .. using a drift motor and esc in a stock truck with custom drift tires on stock rims.
