Today, while staying afterschool, I got my hands on some free shwag. And things I never knew Tamiya made. Gear boxes!


since, this gear box is technicaly straight axle, its gonna be a dragster. Each motor powers one side of the gear box, with one straight rod connecting them, so each side is equal speed.

but, i need a custom long chassie to fit this.

Just pictures, keep you guys guessing on the rest of my plan.

Sure. Where the hell is it explained the HTML format of posting and sizing pics here at xmodworld? At xmodrc you code the size in your post(ie. image width=500 will give you a specific size picture).

Re: MY Tamiya twin-motor gear box drag xmod [DMX_Dragster]

I have it down to a 5:1 reduction, xmods arent even that high are they? I dont have a built gen1 currently :lol:

Sweed, get one your Gen1s, and see what the reduction is on the motor pinion to the diff

Cool to see you outta the wood works Jshwaa

Hey. I don't think that gearbox can achieve a ratio that will allow for much speed at the output. I owned one of those gear boxes. Yes, you can change around the gearing for multiple ratios, but it essentially goes from torquey, to super torquey. It never actually gives anything close to a 1:1 turn ratio.

I think this woulda smoked it. Even with one motor. :twisted: Haaa!

BTW, this is what that gearbox is made for.

Re: MY Tamiya twin-motor gear box drag xmod [DMX_Dragster]

I keep forgetting to get dremel parts to cut a chassis

As for the battery pack, its listed a few pages back. Li-po, 7.4v, 1500 mah? Something like that.

Re: MY Tamiya twin-motor gear box drag xmod [DMX_Dragster]

i read this about 1/2 a year ago, amazing how it started up again. i lik how u got the hobby class radio package. its gonna b alot easier in the long run lik u said. when u really look at it, xmods r a very cheaply made rc... but then again, for $25 and some fun times, who can complain? wats the chassis look lik these days? decided on a battery pack yet?

How would the upgraded 5 spoke rims look up front (DeCorsa's, I believe.)? It would keep with the sportster look, and won't look like bycicle wheels.

Did I ever say it was done? :lol: Not certain on what wheel and tire combo currently, so no need to cut the axles for non-existant tires

looks tight man, i like the flat black look, it adds the right touch to it to make it look like it'll stomp any car that gets in its way, nice dragster choice

Re: MY Tamiya twin-motor gear box drag xmod [DMX_Dragster]

Are Mods changing my pics to links? Ive used 800x600 forever with no intervention before.

Thanks Junk. As for the board, it would been more expensive and more work to hunt down parts and keep the xmods EP.

Re: MY Tamiya twin-motor gear box drag xmod [DMX_Dragster]

Probally not, I dont want to deal with paints. Another reason its flat black is because the blue/white two tone underneath went bad, due to some old paint I had that clogged up, and sprayed like crap. Plus flat black is mas machos :lol:

edit:

(give it time to update to the proper width)

Re: MY Tamiya twin-motor gear box drag xmod [DMX_Dragster]

Im not sure what to do for rims. I saw some foams on another Mini-Z, really wide ones. Theyd be perfect if I can find them on the web. Maybe do a red rim and white wall combo. Grab some 67 Camaro rims for the front, and paint the foam'd rims in rear.

You CALL THAT STALKING? This girl that liked me stalked me almost all the way home and knows what I do at school. THATS stalking. :roll: She scares me :wink:

Unless she's like 200 pounds, don't complain. Is she hot/cute? My friend likes this Haitian girl. She's on the wrestling team. She can probably beat the crap out of him.. But she's pretty hot..

I'm diggin' the red headlights, really looks like an old classic dragster. ;)

Thanks man :)

Painted the chassis flatblack, and made a V8 for it. Cut it up so it sits low in the chassis, but clears the tierod and enough for the servo.

Re: MY Tamiya twin-motor gear box drag xmod [DMX_Dragster]

Got it painted today, finally found what I want.

To encourage some badassness, and to separate from the normal high-glossyness, I went the right way...

FLAT BLACK

Its gonna get a bit of a dragracer treatment, since Ive lost some pieces like headlight, tail lights, and bumpers. So the head and tail lights will have covers, and Ive got the headlight ones in

The camera is making the paint appear very grainy :( But its so tight in person

edit: head light covers in:

Re: MY Tamiya twin-motor gear box drag xmod [DMX_Dragster]

The radio works great, I was testing it with the propulse last night. figured out that little knob is the turning radius.

I may use this servo:

http://www2.towerhobbies.com/cgi-bin/wti0001p?Q=1&I=LB7168&P=3
Or one that color0 used in his Iwaver-xmod. Waiting for word on what that one was

Re: MY Tamiya twin-motor gear box drag xmod [DMX_Dragster]

Got my radio and reciever today from CowboySiR. He seems to always be my hook-up on here.. :lol:



It fits right in too;

But its gonna need a servo, sooo... since Im not worried about a low CG (its just going in a straight line) I can mount it side ways as well

SSMT Tires? Talon's aren't bad for traction, but if they start ballooning or get too much side bite, the tires tear at the end of the tread thing on the side...

Got some work done the past few weeks, or one, when ever school let out. Gotta chassis design working, but no pics really...

Gonna use a hobby grade rx tx and esc most likely. And probly gonna be from my favorite Canadian on here.


SSMT tires, maybe?

Re: MY Tamiya twin-motor gear box drag xmod [DMX_Dragster]

Blast, Ive been meaning to bump this for a long time. Havent forgotten about it, just playing around with chassie design. But I maybe able to score some free sheets of aluminum from my friends dad. Hes a metalologist? Something like that, companies goto him when they need to know whats the best material and such. My friend says that he could probly get me some sample plates for free. And those are just big enough to do the back section.

And I started some paint work on the body, if you look around else where, its in the BG of one of my pics. :wink: :wink: :wink: :wink: :wink:

Re: MY Tamiya twin-motor gear box drag xmod [DMX_Dragster]

The other colors were just red or black.

I got good news, and bad news.

Bad news is, I havent made any sort of progress recently......

Good news is, Ill start to have money, and the weather is warming up for painting. :) So this should start to make progress in a few weeks.

Got a color combo I like, tested it on my MP3 player.

2 coats black, 3-4 coats candy. Its a real deep burgundy. The red shows through in highlights in brighter light.

If I were you, I'd just wait for the weather to warm up. Wait and do it right instead of rushing it and screwing it all up. I have the same problem with my SUT. It stinks. :x

But, I like your color selection. I think it'll look nice. And seeing your painting skills on the Mustang, I think it'll turn out awesome! :)

Its like 44*F outside, 50*F in the garage, too cold. Feeling tempted to just do it in the bathroom with the vent on. Done it a time or two before.

I think your idea would look real cool. Weather been too cold here (25F high, and 4" snow today) to paint also. Very interested to see how it would come out though.
