New dremel = tricell = need help

Zephyranthes · #1 04-28-2003, 10:52 PM

I just got a new dremel and I want to make an tricell. How do you keep the wires out of the way.

What would be the easiest way to do a tricell with 2 cells in the chassis and one out the window:

Horizontal
Vertical
Bunta's vertical pcb and cell mod

Any more than 2 cells and I would use a Zip Zap, but thats just me. I like the bunta vertical 2 cell, you still have to stick a cell out the back. In fact I was just thinking of trying that mod on my Fairlady Z. I have about a dozen cars that run, half zips, half bit/ microsizer, and all my two and three cell cars are zips. Three cells fit nicely in the chassis of a zip zap

He's right. If you do a tri-cell to a bit, you won't get much benefit out of it because it will spin out, or flip as soon as it get's to a high speed. It will go straight if you put all of the front end parts out of a Zip into your bit. (I have done it) I got my Bit to go 10 mph. I can't stand multi-cell bit's for the most part. They can't hold a candle to a tri or quad-cell Zip Zap. Lower center of gravity, better control, much more stable at higher speeds.

I agree, I tried a dual cell both under the body, and hangin' out the back window. Either way equal silliness. Unless you get pullback wheels or find some other solution. Under the body wasn't bad, but flipped way too easy. Hangin' out the back was was actually funner because you had the potentential for wheelies, but it flipped way way too easy.

Dual cell Zip Zaps are still easy to control, and don't flip nearly as easy. I just finished my tri-cell zip zap last night, and it smokes. It way fast, but about as easy to control, and flips as easy as my Bits and Microsizer do with single cells did with a 3.2.

Here's my tri-cell Zip Zap. it's my first micro RC that I'm truly satisfied with.

...and don't worry you'll find plenty of uses for that dremel.

i have a bit that is very fast. dual cell with springs for suspension and a clone motor and clone pcb. the key to keeping a bit going straight is to take the wheels off the rear axle and epoxy them back on. ive found that most of my peeling out woes is caused by flex on the rear axle. also tomy axles have crappy glue and the non drive wheel slips after a week or two.

yea i agree with hog on the gluing of the axle.. mine were like that new... i did the dual cell mod with both cells running lenght wise in the chassis. whith the pcb upside down on top of them it corners excellent. flips on carpet but not to bad on regular floor. where it will slide just a bit.. i have spring suspension. although im not sure how much it helps..

on my second dual cell also internal like the above stated car. i have the muscle machine tires on all 4 wheels. it really handles good!! when it can get traction...

both are dual cells with 2.6 kit motors..

Not to offend here, but I have seen your bit in action, Hog. The kinda fast we're talking about does not happen with epoxy'ing rear axles. It still won't track straight. You still need to mod the front end parts to go REAL fast, or you'll spin out.

ill have to film to prove you wrong then. i was going pretty straight on an fairly warped wood floor the other night ago. i still peel out sometimes but if i clean the crud off it bites like a bat outa heck and runs the 12foot length straight as an arrow. in my friends basement with a smooth concrete floor, it goes easily the 18.wahtever feet it takes for a 1/4mile probably in the high 2s or lower 3s but i didnt time it due to lack of stop watch.

just wait til you see my new clone in action. it steers better than anything ive owned yet. its just not ready for the high speeds.

crazydave · #9 04-29-2003, 05:25 PM

Hmmm, I'm staying out of this one. I'm just saying I likes me car, that's all.

I am planning to make a video, but not to prove anything, I can take little 30 second Quicktime videos with my digicam if I wanted to do that. I actually was inspired by Hoghjowls little production, and I'm hoping my MIL will let me borrow her digital camcorder so I can make a little movie of my own.

I need some cool stunts to set up. Anyone ever try a wall ride? Or how about a corkscrew loop-de-loop thing, like one of those hot wheels tracks. I wonder if you'd have to steer through one of those.

Zephyranthes · #10 04-29-2003, 05:36 PM

I've had my dual cell for a while. The speed doesn't amaze me anymore even with a perfection 3.8. The car goes straight because it has Zipzap wheels and double steering spring. I'm doing a lying down vertical cell. If the wires to the third cell can't fit, I'll stick it out through the holes I made in the chassis. I'm stopping by RS tomorrow to get a soldering iron tip cus mine is broken and I will also get their no heat 4x stronger solder in a plunger type bottle. This will enable me to make a ocnnection on my batteries witout overheating it and get into those tight spots without burning the wires or chassis.

I've done a loop with my dual cell with my Hot Wheels Powerloop set. It barely made it around because the loop is very big.

hogjowlz · #11 04-29-2003, 05:47 PM

i was doin wallrides on a big piece of styrofoam once

Zephyranthes · #12 04-29-2003, 08:34 PM

I went to RS today. I found out that plunger type solder stuff does need heat, but can be done with low heat like a match. It is much easier to do with because it is liquidy and you just apply it then heat it up. You don't need to hold the solder there leaving me an extra hand.

I also got the new upgrade kit with the 2.35 and 2.8!

Well, to back up the HJ-mobile, if you're going to stick with a bit size car, definately do the pullback rear wheel mod like he did. It's the sweetest traction mod I have seen. It will allow you to track straighter than you would w/o. I don't think however, that you could get it going 10 or 11 mph w/o spinning out or flipping. At lower speeds you can keep it straight for the entire 1/4, but I have a hard time thinking that you can make one like say...bdebde's Zap and still control it. I have tried many times.

I don't really have as much fun with my 3 or 4cell Zap as I do with my single cell MS pro anyway. I can't keep them on my track. They're fun for 1/4 mile, but that get's old. HJ's dual can ride some crazy straight wheelies. I should make another dual.

My drag car is pretty hard to control as it is (no traction), even in the zip zap chassis. The most fun car I am driving now is a 2 cell zip zap with a booster pcb and the new racing zip zap motor. It has loads of torque. Even without the boost it has decent torque and is way faster than a single cell.

crazydave · #15 04-30-2003, 08:54 AM

My ZZ Supra is controllable enough for large roadcoarses, but does have a tendency to flip. About the same as a single-cell MS or bit with a 3.2 or 3.8, but much faster. You just have to slow down when you turn.

I just tri-celled my other stock gold Civic ZZ last night, and it don't flip, but its not getting very good traction from the ZZ tires. I think it's faster even with the stock PCB, but I have 12:1 gearing in that one and 9.86:1 in the other. So it's probably just winding up quicker.
