You are welcome club. BTW, the Tx joy stick contacts are rotary, not sliding (my mistake). As a last resort, try using a few drops of "051 Pastics Safe Electronics Cleaner NF" by www.greenchem.com. This product is non flammable, non conductive, and is safe for foam. I used this on my PZ on/off switch the other day and it runs much better. It has more power and the blue light is much brighter. It also needs very little right trim now. This makes me think that the switch was dirty from day one. That, of course, was most likely causing excesive resistance which in turn was shutting the PZ down. HTH.
