will a 3.8 motor work on a zip zap kyle..also if you dont like heavy bodies you can make hot wheels kit cars bodies fit and they are "light" the gearing and motors fit just as well.

I was able to fit 2 cells underneath without swapping PCBs, all you need to do is cut out the latchbox in the middle (that the lock inserts into on the charging base). Everything fits and snaps on like normal. The second cell lies parallel to the original cell, instead of perpendicular like Kyles Mod. This may help on turns as the weight is centered instead of being left-side heavy. But you may sacrifice any gains in speed that Kyle mentioned, by keeping the PCB board stock.

Kyle, I am curious as to why you transfered the charging base from the ZipZap controller to the Tomy controller in one of your pictures? Am I looking at it right? Is that what you did? The ZipZap snaps right onto the Tomy charging base, so I wasnt to sure what that pic was about. Also, I tested one of your 3.8's on my dual-cell 2.4v ZipZap w/12:1 gearing and it pulled approx a 4.74 sec run on a BitDra-G regulation "Open Modified" length track of 20'. Could you try testing the run with the Bit Board and 3.8 too then post the results? I would love to see the speed gain possibilities in terms of numbers. I am kinda disappointed w/ the takeoff speed off the line on the ZipZap w/a 3.8, but the top end is great. Hopefully the Bit board could remedy this. As I see it, if you could gain enough lead on the takeoff, and possibly keep the lead long enough before the 3.8 closes in, theres a possibility that a slower motor like a 3.0 could take a 3.8 on a drag. What do you think?

For more info on my test run, read the thread I posted on it...

Kyle, I'm curious too. Wouldn't it be easier to just modify the ZipZaps controller to flip forward and reverse?

QFM,

Yep, I did transfer the Zip Zap charger over to the Bit Char-g controller. My Zip Zaps didn't fit the Bit Char-g charger very well. They either wouldn't charge or would fall off, so I decided to swap the charger over. With the new set-up, I can utilize the hook that holds the Zip Zap on to the charger and then flip the cover open to press the release button. That just works better for me. I'll test the speed for you tonight. I'll set everything on the car up the same way you did in your test. I'll try to post the results tonight.

gRC,

I wanted to use the Bit Char-g controller because I'm getting 60 feet in range with it, and I don't get half that with the Zip Zap controller.

Kyle,

Thats ridiculous range! 60 feet! Wow, I am so jealous!

Nevermind that we probably couldnt see the car from that distance! Are you just using a the standard 3 mod combo (cripple cap/telescopic ant/cat-5) to boost range? Man, thats great!

Thanks for doing the test run for me. I didnt even think about also having you change the axle gearing too. That would definitely make it more accurate. I am glad you thought of that. I would eventually like to test out all kinds of combos but I need a better timing system, and chronograph. All the runs with my Zip were just under the 5 sec mark, and I know i could do at least a half second better if I can solve that slow start. I thought the 12:1 gearing would have helped but the Zips just have more weight to push than the Bits I guess.

Anxious to see your results as well as any other cars combos you may have also tested. I never even tested the Zip stock, cuz I was too anxious to mod it. My guess is a 9-10 sec run with a stock 2.35 motor.

QFM,

I've got a stock Zip Zap also so I'll time that one and post both times tonight. The range mods are the big 3 (cripple cap/telescopic ant/cat-5) and the range was measured outside in an open area (which makes a big difference) and using new batteries in the remote.

Hi Everyone,

Well I got out my stop watch and timed the Bit Zap and I'm really afraid to post the results because I know everyone will think I'm crazy, but these are the true times for the Bit Zap and the Stock Zip Zap. First, let me say that I made 10 runs with each car and dropped the 2 fastest and the 2 slowest times, and then I took an average of the remaining 6 times to come up with a consistent drag time. The Bit Zap with the Dual Battery mod, 3.8 motor, and 12:1 gears ran the 20 foot drag track in 2.81 sec. That's right, 2.81 sec. I couldn't believe it myself, especially after seeing the QFM Zip Zap Dual Battery time. The Stock Zip Zap with the 2.35 motor and 12:1 gears ran the same 20 foot drag track in 6.53 sec. I know the stock cars are supposed to run on a 15 foot track but I wanted a comparison to go with my Bit Zap and the QFM Dual Battery Zip Zap. One other note I should add. I was using Bit Char-g tires because they don't have any tread and they are wider which means they have more surface area for better grip.

I believe that this is proof that It's not necessarily the extra weight of the Zip Zap that makes it run slower. It is the amount of power supplied to the motor by the circuit board that makes the biggest difference. I'm sure you guys will have questions, so I'll be glad to answer anything you want to know about.

Wow Kyle that's insane speed.... What times are you getting with a regular bit with a 3.8 single cell?
Is the zz just a blure at that point or what??? LOL

Excellent info Kyle! The time you registered w/your 2.4v Zip modded w/a Bit board (2.81sec/20ft) is practically HALF of what my 2.4v Zip w/stock PCB registered (4.74sec/20ft)! That is great! That really shows the Zips potential... Now imagine a higher gearing!

Well, I put my 2.4v Zip and 2.4v Bit on a diet scale (not very accurate) and the Zip is roughly a little more than twice the weight of the Bit. Now because that weight is significant, i would still have to say that weight plays a big part, But with the time you recorded, I would have to concur that voltage definitely plays the BIGGER part! If anyone has an accurate scale i would be very grateful if you could weight a stock Bit and Zip just to see the actual difference...

BTW, Kyle your time is an accurate comparison because I also used BitChar-G slicks on my Zip for the same reasons you did.

I was also surprised that the stock did a sub7 time! I was expecting a slower time. When I get the chance i will try to time anything and everything I have, just so we can QUANTITAVELY see and compare performances. HeeHee. This is too much fun!

Lastly, here is a pic of the spring mod on the 2.4v Zip. As you can see, there is much more play in the struts than on the Bit! Very cool! Can definitely take on larger bumps and rough tracks smoothly!

Greetings everyone!

Wow the cat's out of the bag here, I modded a ZZ with the above mentioned 2 cell mod, and I went and used the PCB & Tx from a dead OEM Bullet I had lying around. Unbelievable!! I have like 50+ feet range and incredible acceleration. I didn't time it on a drag course though,, 8-( But all my buddies jaws hit the floor when they watched my little car go! I charged my car with a Black & Decker powercell (3.6 volts). The voltage of the on board battery has alot to do with the performance of the car, I don't know if I had a "full" charge with a 1.5 minute charge. I am experimenting with longer,, but too long and bye bye! Smoke and bad smell!

What did you other guys(kyle & QFM) charge your car with?

QFM Racing · #41 09-30-2002, 11:43 PM

So its definitely the PCB then. Thats the decisive factor in juicing the 2.4v mod. Its good to hear that the clone PCB's also have the same potential that the Bit boards do.

I use a 4.8v AA battery box with a charger port wired to it. I charge for 4 minutes. I figure if you use 2 AA to charge 1 cell, then I should use 4 AAs to charge 2 cells. Hehe.

bitchar-gmotors · #42 10-01-2002, 06:36 AM

QFM,

I've got a very accurate electronic scale, so I weighed the Stock Zip Zap and the Stock Bit Char-g to see what the weight difference would be. The Bit Char-g weighed 0.780 oz or 22.1 grams. The Zip Zap weighed 0.895 oz or 25.4 grams. When I take the body off of the Zip Zap and just weigh the chassis, I get .700 oz and 19.8 grams. So without the body, the Zip Zap weighs less than the Bit Char-g with the body on, and if you race these two side by side with the same motor, you should get an Idea of the difference that the circuit board really makes.

payaso,

I haven't timed a regular bit with a 3.8 motor yet. I need to do that. Also, the Zip Zap is not quite a blur but you definitely don't want to run head-on into anything at that speed. It really could blow the cars components apart.

Kyle

bitchar-gmotors · #44 10-01-2002, 06:44 AM

Bunta,

I'm just using the charging stand on the controller to charge the car. I leave it on the charger for about 4 minutes. I'm thinking about making a stand alone charger for it though.
