This is BRENTG's terrific Boeing P-12 scaled up to 50% for RF-7.5
A great "between the wars" biplane that holds a special place in my half scale hangar, thought I would share it.
Decent scale-like flight performance with full power verticle stalls and appropriate top speeds. Torque curve and prop pitch/diameter adjusted to noticeably bleed-off RPM's under heavy loads (steep climbs)
and spool-up again during the dives. Also added ailerons to the lower wings to improve the roll rate...
