I have a SiG Cadet almost ready to cover. I'm installing a .46 size electric motor. Love the Sig kits. I've built CG kits. Didn't like the way are put together. However, the planes flew very well. My first RC model was a Falcon Jr. Used a .049 engine. Built the transmitter from a kit. Just to prove it could be done I built the receiver using a 250 w iron.. I let each item stick thru the circuit board. Tined the tip of the lead thru the board. Let the iron tuch the end of each lead with the iron while holding the solder at the board, removing the iron just as the solder melted.Flew this plane for about 10 years, then gave it to my brother. Let keek SIG afloat!!!!
