If you fly DA engines like alot of us do TBM has a really neat adapter that you might be interested in. I was finishing up an Air Wild 29% Edge540 and needed to adapt the DA ignition cable to the standard battery/switch fitting. I've cut and resoldered wires in the past but Troy Built Models has a really neat adapter for just that purpose. No more cutting and soldering to mate the DA ignition plug to athe universal r/c plug. Try it out. It's pretty easy.
