RE: BALSA USA 1/3 SOPWITH PUP?????
I used the basic kit and much up-scaled it. I made it as a replica of N5182 "Sheila". G62 has PLENTY of power. With a custom John Clark scimitar WW1 24X10 prop, spinning at 7200 RPM's, you only need about 1/3 throttle to cruise around..... and my model is heavy at almost 40 #'s wet! Here is a pix. I have tonnes of construction photos for all details, especially the landing gear, tail skid, instrument panel, etc.
