View Full Version : Troubleshooting range problem

I recently did a 2x2 FET install on a Firelap 2.0 board, and for whatever reason, my range is now about 12 inches.

I'm not sure what the result of an antenna shorting on a battery terminal, so I guess that's a possibility.

The weird thing is that the board seems to function just fine within 12 inches.

I've tried every possible antenna location and triple-checked the antenna wire for integrety, so that's not the problem.

I also tried a different controller and different crystal sets with the same results.

Any suggestions?

It sounds like its toast, but were the batteries installed when you did the FET's? If so, that was a disaster waiting to happen. If anyone else reads this, remove all batteries and use a static strap when soldering PCB's. If you discharge the static that is built up on your body, through the circuit board , you can damage it severely.

Iwaver/Firelap PCB's tend to do that, regardless of the FET modification. I have had 3 Iwavers lose their range for no reason whatsoever. I would use better electronics.

Yeah, that's about what I figured. I always take the batteries out when soldering anything, and while I do use a wrist strap when working on computer stuff, I never thought to use one for working on Mini-Zs. I guess I figured the electronics weren't that sensitive.

I realize the electronics are way inferior, and I firmly believe in the superiority of Kyosho, however it is fun to get an iWaver/Firelap actually running well. I ordered a replacement board, but it's mystifying what happened. Nothing looks burnt, and I can't imagine how I might have shorted anything. Oh well.
