I don't have any experience in the receiver portion of the electronics. Sorry. From looking at the RF from the transmitter, I can only guess that a number of pulses is sent; the resistors and...

The part number is FDV303NCT-ND for $.55

I can't wait till I get a big enough order so I can get some SMD LEDs for some light mods.

If you are using a duel batt mod then I don't think you should try shorting the resistors unless you really know what you are doing. In the duel battery case I would suggest using 4 mosfets if you...

I believe that swaping out the PCB will make a diffrence. I made my measurements parllel to the motor and found that the resistance across the H-bridge on the ZZ was prety high. I was interested in...

Try as I might, I can not increase the voltage to the high side of the motor. I bet the no reverse mod DOES work great. The voltage drop is still about 0.3v. I tried a darlington transistor and...

From my experiments with those resistors, I found that current continued to increase to the motor the smaller resistors I used. Actually, I shorted them and I didn't notice any negative side effects...

Don't forget about the voltage drop across the diodes. I am not an EE mojor, but I have read that there is a 0.7v loss from the average diode. The transistors that run the motor loose about 0.2v...

Yep, there is a voltage doubler on the board. It is labled A3_3V. The output seems to be the center pin between the other two. Right now I am trying to steal from it and run some lights, but I...

It does seem like removing R18 and R17 would help. I havn't noticed much loss across the upper transistors so I havn't bothered with them yet. Now that I have more current going through the motor,...
