Bit TTTT

Daisycutter · #1 04-23-2003, 09:45 AM

I plan to build a TTTT truck using the RX and parts from a bit car.
Anything RC here is insanely expensive.A bit clone costs less than half of what a standard servo would cost. I can get the faller car here but I'd prefer to use the bit bits for a truck.I used to have a HO scale 2-axel truck so I know the layout pretty OK.....some pointers in the right direction would be really helpful,like why so far nobody has done it, or why there isn't much about converting a bit into a truck.

Any feedback would be appreciated

Cheers

I've seen semi's,you know tractor trailer(without trailer). They have 2 axels on the rear but only one is powered. Might try e-bay.
hope that helps a little,good luck

I want to build something that looks like an off-roader and later on build more complex models like maybe a MAN 5t truck or sumthin like that.On roaders are somewhat 'mild' .

how about building a truck with 4-wheel-indepent suspensions?
I guess the size will be bigger that the regular TTTT...

way ahead of you I'm building that right now about 1/20 scale not too sure I got a design but i tend not to draw plans. I'll take pics of the building and then post them as I move on

cool!!

Can't wait to see your pics.

What kind of gears are you going to use?
I guess the worm gear is a little bit slow for the off-road project.

Tamiya has a educational kit, I think maybe I can use the gears.
here is the linke

Ok the few details I have to tell you since I hate plans is I’m going to model it after the Suppressor in carmageddon 3 so it’s going to be a 6 by 6. It will be 4 wheel steer. I want it to be a rock crawler, since my house has lots of rocks in the land scape plus if i needed to drive it some place else I would just go to the mountains 10 min away. For the gears I’m going to use the same thing as TTT but trying to find worm gears in that size I have found out is impossible so I’m going to use wood bolts I’ll get a pic to show you what I mean.

this is what i'm trying to build

using bit electronics has been discussed briefly...i for one have encouraged it as well.

the reason most don't is that they are trying to create a fully proportionally controlled tttt to have the kind of fun you can see in the tttt trials pictures and video's. just can't do that with a bit electronics.

look forward to seeing your project develope!

I think It would be better to use the 4x4 off road trucks for the pcb
They have tank steering so I dont know if you would want to do normal steering
they come duel celled stock so hem might be able to handle more voltage and are also alot smaller and simpler

:ö: if you could post some pics of your bit electroncis (blow up or just show all the electronic parts) then maybe i could think of ways to modify it for TTTT

Thanks killer I'll show you some lectronics

Here is a modifyd one.

:ö: i have some questions for you, i noticed on your drawing that there are 4 wires that came from the pcb to the front part of the car, and as i understand bit charg, they are steered by an electromagnet that spins in the middle of a manget, correct me if i am wrong.

killer · #15 04-28-2003, 07:01 PM

:ö: remove the wires from the steering magnet an try attaching a 7mm (pager motor) or smaller motor on it, so when you press the left or right button on your bit tx, the motor should spin, and once you released it the motor will stop spinning.
