Mosfet Power for single Cell Bit´s!!!!

[Grasziege]

Hello People,

We developted a Mosfet modification for single Cell Bitchar´s
The car gets not much faster but the Motor has more Torque!!!

Here the complete guide how to doo it:

Including a new icon. Use it!

I recently did your dualcell h-bridge mosfet mod and all I have is reverse--Very Powerful reverse All my wiring is correct, can you tell me which mosfet does what in the picture on this page http://www.universalhost.de/html_bit...-bridge2_4.htm

I need to investigate the mosfet connections having to do with the 'Forward' circuit but I do not know which mosfets to investigate.

Thanks!

Why do you need a different mod for single cell and dual cell cars?

Also, has anyone measured the max current available to the motor with this mod? I would like to do this mod with a dual motor mod, where it would make a HUGE difference. If my 2.6's can each draw 200mA, but a bit can only put out 275mA, that's not good. This mod is absoluely necessary with 2 motors, or else it's like 1.375 motors!

I wish i could do surface mount!
I need to buy a kit or something because that's great!

I really don't know why there is a different mod for the single cell, prolly has to do with amps though.

I'm just a layman messing around a dinky little rc car on wild Saturday nights. Now I need to figure out which transducer (mosfet) does what on the pcb. Do you know looking at that link I enclosed? My board looks just like it in format. unbelievable power, no idea how the single cell would behave. I just have one direction working right now. have to check my soldering, replacing those little transducers is not an easy task at all, but now I'm hooked.

Wha? All you need to do is to remove one of those black things, and that other big black thing?

C'mon, you can do it too! You don't have to anything about electronics, just follow the directions!

Well, the thing is, I DO want to do it, but my chip looks like this (shen PCB) http://www.universalhost.de/html_bit...t/3platine.jpg

And, I don't know what to take out? There is something circled on that page, but there is nothing there on my PCB.

Here is a pic of my pcb.

Yea, this is really wierd.... I can figure out how to do it, and would experiment on my pcb, but I need it, for my project (I don't wanna wreck it!)

Whoa! I was gonna reply at the exact same time as you! It showed your three post, I hit reply, and the "Topic Review" at the bottom shows four now!
This is a waste of a post!

Here is a easier link to read, it's in English! http://www.universalhost.de/html_bit/

if all your getting is reverse, couldnt you just switch your motor wires around.. maybe im just confused here...

[xatu]

If you are talkin about me switchin wires, then yea, you're confused. I didn't say nothing about my motor goin in reverse.
