building a vehicle with sponson mounted guns, I am using a clarke board and need to switch flash and recoil servo independently for each.Anyone done this before or can point me the right direction

Off the top of my head I'm thinking Pico switches. You'd need a couple open channels on your RX though. You could Pico the hot wire for the recoil and flash seperately, then turn on/off those switches to get power to those units or shut them down.

The big draw back to pico switches is that they don't like to be switched on and left there for any length of time - you'd need to be careful to only have them engaged when you wanted to fire, and not have either one or the other 'on' at all times.

Option B would be to use the Turnigy light switch in place of the pico switch to control the live wire (also cheaper too)

Was unaware of the issue on the Pico's Martin, I use them to control the lights on my r/c construction stuff and never had an issue. I leave the lights on for the entire length of a batt run time.

That's what I thought, until I suggested to somebody else that he use them to control some lights - who then turned around a month or so later and complained that the relay had given up the ghost... Could have been a bad relay, could have been the idiot wielding the soldering iron, who knows? Not all relays are intended to be left on for long periods, and I concluded that this was probably the case here. At 20 quid a pop I'd certainly prefer to err on the side of caution if it was my money.
