Flight results!!!
Flight #1. ROG into a bush! Caused by a slight left turn tendency. Battery came through tissue floor, knocked nose off of the motor.
Replaced the cockpit floor with cross grain 1/16" balsa. Glued the nose on and glued in a little right thrust.
Flight #2. ROG... Cross breeze came up... I over corrected and plane dove into ground. Glue wasn't dry on motor so knocked front off again... This time I lost the little spring from the prop shaft.
Re glued nose.
Flight #3 Hand launch into slight breeze. FLEW GREAT!!! Even though I had only used one rubber band on the wing, which ended up slightly eschew, the little PPB Pup flew better than the WMF! And the power off landing was straight and the glide angle was much moreshallow than the WMF.
Weight now up to 38 grams.
I know this little stick and tissue plane won't hold up as well as the WMF, but it is a much more forgiving flyer than the foamie.
I think this power system could fly something in the 20" -24" range, as long as the RTF weight was kept under 2ozs... Which will be my nest test.
Good luck
