bitzap?

malform · #1 06-04-2003, 08:00 AM

Last night I bought a zipzap… A couple hours after purchase I was soldering an extra battery in the chassis. So after I had myself a dual cell zipzap I started thinking about taking the electronics out of my booster bit and putting them in my dual cell zip. I would think it would give you the best of both worlds.

Also, here is a little project I started on almost a year ago and lost interest shortly after starting (see pic below). I took 2 bit clones (didn’t want to chop up 2 real bits) and ripped them apart to make a 6 wheeled 4wd car. Also I made the middle section a little longer so I could add more cells to it, the thought was if I was going to have 2 motors I better have more cells. As you can see in the pic the final chassis ended up being just a tad longer than a zipzap.

But anyway, I was just wondering if anyone has tried to do either of these 2 things. If so, it would be great to hear about how it went.

I've made a couple of BitZaps. They rock the house down. My current BitZap blows away any of my dual cell bits. Awesome handling and blazing fast speeds. The boost button is sweet icing on the cake.

The BitZap is the best of both worlds as far as I'm concerned, and very easy to make. The Zip Zap chassis has plenty of room for dual cells and a booster board, without having to flip the pcb. Evereything looks nice and professional.

Those two rear axles look awesome!!!!

Rock, I was hoping someone already made a bitzap.

So did you solder the bit board into the zipzap, or did you just take all the bit stuff and swap it out with as little soldering as possible?

I would think I could just glue the stering coils in the front, and only have to solder the battery lines in.

I've swapped out all of my early modeled zip zaps with bit pcbs. I also did a 6x4. The added motor gives great torque but steering is a lil wide. I'll post up a pic if I can find it on my drive.

I would love to see pics of the 6x4... What did you do for a body?

I considered soldering in the booster board to be the easy way out. I’d much prefer to solder 8 wires than try to transplant steering coils and stuff. I think the whole pcb swap took me about 20 minutes. The only problem I ever have is trying to get all three wires soldered to the positive terminal. That can be a pain in the neck.

Unfortunatly the body has been sitting in the shop forever.

Here's the pic.

I have a hard time getting the wires into those little tiny holes in the board when I try to solder in new wires. Any tips on doing that easier?

That 4x6 is awsome... How many cells you got in there, and what motors?

Buy yourself a set of helping hands from Radio shack they are a big help.

*edit- I got a dual button cell inthere and I'm using 2.2 motors. I gotta upgrade to a normal cell dualie.

I use a solder sucker to clean out all of the holes before resoldering. Then I use some of that blue-tac stuff to hold the wires in place while soldering. Once I'm done soldering, I carefully remove the blue-tac. Piece of cake.

I have a booster bitzap, I love it. About my favorite car to drive. I also tried something a little different than your 6wheeler. I glued 2 back halves together for a 4 wheel drive without steering. That car has my new speed record. With a mosfet modified pcb and kit racer gears, it went over 13 mph!

Give that man a cigar!
The solder sucker makes it all so easy.
I've never tried blue-tac before, it sounds great!

Ok, last night I started to switch all the electronic stuff around, didnt seem as hard as I thought it would be... Only thing is I mixed up those little steering lines! I cant seem to get them to work. Is there a secret to get them right?

I think it is: Black wire on right coil goes to L terminal, plain one to the bat +. Black wire on the left coil goes to Bat +, plain one goes to R terminal. Hope that helps.

Make sure you clean enamel from end of wires. I get a drop of solder on each first, to melt the enamel back.
