Have you considered larger motors like a 140 or 160 size or a smaller gas engines???? Not a lot of people know this unless you own one of these ARF’s made by Great Planes. The P-6E Hawk or my favourite plane of all time the PT-17 Stearmen, both are short coupled bi-planes and therefore need a lot of extra weight in the nose to balance them. The manual recommends approx. 18 oz of lead in the nose, so why not use that weight up with a larger engine??
It seams like the designers at Great Planes are encouraging us to put a larger motor in them. They even give you a nice thick and strong firewall, and ground clearance for a larger propeller. “Thanks Great Planes”.
Because of this you do not lose any wing loading and the Pt-17 comes out to about 25 oz/sq ft, including the bigger engine. These Bi-planes with a bigger motor have an enormous flight envelope, from very slow to very fast and all the thrilling aerobatics in-between. Once you fly one of these bi-planes with a bigger engine like a 160. I guarantee it will become the one you take to the field the most often, cause depending on your mood that day, you can fly it, any which way you want.
Check my Stearman in action with a G2300 engine swinging a 17 X 7 APC prop on You Tube. The Stearman makes contact with the grass, so I called the video “ Parting the Grass “.

You can never have too much power, as you can always throttle back.
