ZZSE FET MOD VIDEO: 35 degree climb video, wheels spinnin!

Okay, here is the CZT fet mod...

I cracked this nut a while ago but just didn't have good proof..

Well, here is the proof that it works.

There is proof of the power of the CZT fet mod I do.

Note the only thing keeping that sucker from climbing a wall is merely traction, and that is with the red turbo gears and the NEX purple motor.

I took the body off so that no one would accuse me of having an extra cell in there or something.

The file is about 2megs, so be aware that if you have dialup it might not be too much fun lol.

It starts out at around 25 degrees, then I tilt it to nearly 45 degrees and it just keeps them wheels spinning! It wants to continue to climb, but there just isn't enough traction and if I turned it to 45 degrees it would have just slide down due to lack of traction.. LOADS OF TORQUE AND SPEED!!

Enjoy.

Okay, here is one of massive drifting.. This is with the sticky all-weather tires too.

man, do that fet job on my zip! great vids.

You da man CZ.

Tried your fix, and it works pretty good. I think I'm getting about the same results you did.

Thanks for sharing.

Crazydave,
did u do the bypass mod yet?

You have to remove a resistor, then connect one side of the H-bridge directly to fully drive the gate on one of the 6401s.

It really opened up a whole new world of speed for my bit..

Yep that was the fix I was talking about. I had already triple stacked the N-channel FETs on the bottom, and double stacked the P-channels on the top, so it was no prob just to pop that resistor, and add the the jumper.

It definately gives it enough power to wind up a faster motor, like the Perfection 3.8, even with the red ZZ gears, but I still seem to have a tad bit of lag off the line, are you noticing that? I'm gonna play with different motors, and gearing tommorrow.

I'm gonna try to get a vid together tommorrow doing side by side drags with a stock unmodified ZZ, and a FET modded bit, and we'll see how it compares...

Make sure you dyno them with the "wall climb" dave

. patiently waiting on these results man!

OK, I didn't get around to making a vid because I was busy experimenting.

I determined that the lag off the line I was getting is because my battery wasn't getting a good zap off the controller, so I had to rig a charge base, to make sure he battery was getting a good zap.

With that out of the way, I'd have to say Cyborg Zero's mod is a 100% success.

It seems to be like a FET modded car, but with the added weight, and I think because the SE uses 2 smaller cells, they'll never give you the punch of a peak charged 1/4 AAA NiCd.

At any rate the SE is now a much more enjoyable car, which great because I have an excuse to buy that SE Chevelle now.

Here's what I was planning with my video, I was going to run the cars with the ZZ red gears, and a Perfection 3.8, because those are my 2 most consistant high RPM motors. I'm going to do a flat drag with a FET modded bit, and a stock Zip Zap. I'll do 2 runs with each, switching the motor to eliminate that variable. Then I'll do it again on a up hill drag. I'm going to tape a piece of poster board up, so the angle will be fixed, but if necessary I might do another set up run with the angle increased.

I'm really curious to see how my comparisons turns out.

Thanks again CZ, you da man.

I'm really sorry if I sound retarded, peeps, but where exactly is the full tutorial on the mosfet mod to the SE, where to install the FETs, what FETs to use, etc.

I'm no techy, but it's probably scattered all in this thread. I don't think there is just a how to laying around.

I could be wrong though.

Great work you guys, I knew you'd get it.

Yeah it's scattered all through the my SE FET thread.

It was in the state of evolution with me starting by getting the FETs in and discovering that they didn't help that much, ph2t suggested using the P-Channel FETs, as opposed to flipping N-channels, because the P-channels turn on at a lower voltage, and Cyborg Zero got the final piece of the puzzle we all been looking for, the hard part.

Cyborg Zero, would you mind if I put together a complete tutorial on putting FETs in the SE, and include your mod, of coarse giving you full credit for the "CZT voltage bypass mod"? Or at the very least I could make a tutorial on how to install the FETs and make reference that they will need to do your mod to take full advantage of the FET mod?

At any rate, I'm all about sharing knowledge, but I don't want to step on anybody's toes.

I kind of already put it together in the bottom of the 9th (no baseball pun intended) page in the SE fet thread.

I have to thank you guys a LOT on this one.....now I can finally FET mod the thing and get the good results I needed. Thanks a LOT guys, especially to ph2t, Crazydave, and cyborgzero! The only question is.....how does it compare with Micro_Amps' mod?
