Hi Lyle,
The Force can be flown with 40 to 46 glow engine. Mine used the OS 40 FP and was great. You could also us the OS .46 LA, one of my Force kit was powered by an ST .46 that flew it really well, way more power than a LA .46 and a much smoother runner. The bell-crank is a SIg 4” unit that works extremely well, same bell-crank on the Primary Force and many other models I’ve buil
Electric:
That’s so simple to do and I did not have the room on the plan to show it. Maybe I’ll make an secondary sheet for the Force to convert it to electric.
