Hi,

My wife and I had a Rascal 40 with a Satio 56. We first flew it without an onboard glow, but the engine kept flaming out on low throttle after a while. I then installed an on-board glow driver and never had a problem flaming out. As for the extra 3 oz of weight, the plane never new it was there. We finally, sold it after having for over three years. I then bought another one. I only recommend two changes to the planes. Add some tri stock around the landing gear plate and replace their metal plates with steal. Have fun...
