I'm not good with speed controllers, the pump is a Tamjets smoke pump, it was working just fine with the Futaba radio, now that I've switched to Jeti, first it did not run, I made it run today, I made a program using a sequencer to make the pump to work intermittent, on the first flight today it was working fine on the always on position then I switch to the intermittent position and it started to do so then it went to always on then I couldn't turn it off in any position of the three position switch, landed with it on and turned turned the engine off ( the pump was still on ) I had to unplug the batt to turn the pump off and if I reconnect the batt it runs even with the airplane off.

Is the speed controller cooked?

Tks.
