I have been using real flight since back in the RealFlight Deluxe days, slowly upgrading along the way. As of today i have the G5.5 software the original interlink controller, not the newer interlink plus. The switch arm, but not the body itself, at the top right of the transmitter broke. The airplane i fly most often is a U-Can-Do 3D 60 from the swap pages, and on that particular model, the switch in question controls the smoke. After the switch broke, i inserted a paperclip into the switch and that allowed me to change the position of the switch reliably, and thus the smoke ON/OFF. Not being someone who enjoys kludging a fix together from duct tape and bailing wire, i order a replacement switch from Tower with plans to swap it out. I desoldered and removed the old switch, and the soldered in the new switch. Everything was wired correctly and the pins were soldered properly. However, the plane is now stuck in smoke ON mode. I checked the switch, and the pins on the board of the transmitter and the switch is properly making and breaking the connection, depending on the switch position,but i can't get the smoke to turn off. Itried restarting the software several times, putting the old switch back in etc., but nothing seems to work. Any idea what i should check next?
