Good day to you Sir, Is there any chance of you letting us all have a PDF A4 tiled printable plan of your wonderful plane please? Many Thanks And Kind Regards Steve 🇬🇧
thanks for posting. nice work. some thoughts for you and your subs. a few modifications would improve the flight characteristics of the model. if no modifications are made to the model, the pilot should be aware of one thing. because the single-surface main wing has been made with a profile that is nearly symmetrical, longitudinally, the lift and drag of this configuration increase the instability of the model, at all times. when mass, aft of the cg, can be reduced or moved forward, the distribution of mass of the model is 'improved'. mass, aft of the cg, could be reduced by making the stabilizers, rudder and elevator a bit smaller. the sweep angle used on the leading edge of the horizontal stabilizer could be increased, slightly. the vertical stabilizer could be one inch shorter; its leading edge could be made without an angle; just a line, at a 60 degree slope. about a centimeter of material could be removed from the trailing edges of the rudder and elevator. remove the fake main gear struts, and spread the main gear struts, so that, the prop does not strike the ground; perhaps, one-point-five inches of clearance with the ground. make the tail wheel as light as practical; or replace it with a simple wire skid. regarding the main wing profile, a better choice would be one that resembles the upper surface of the clark-y (v1) profile; note that the profile is 'tallest' at 30 percent. see link. at :51, and 1:24, the control horns are not correctly installed. the broad fuselage cross-section at the firewall, is seriously affecting airflow, coming off the prop. correct cg / balance point for this type of model is 30 percent of the main wing chord, aft of the wing leading edge. cheers upload.wikimedia.org/wikipedia/en/thumb/6/6a/Clark_y.JPG/799px-Clark_y.JPG
GREAT FLYING SPEED AND STYLE,!! Everyone asks "Gimmie Gimmie blueprints" Peoples, there are none!! Just raw knowledge on avionics paradigms and KEEP IT LITE!!! You all can build a slow flier like this. Notice all real slow fliers have a "Dirty" wing very concave underbelly. That's one of the biggest steps to a slow flier. That and under a pound [16oz] 450 grams and you'll be nice and slow!!! Keep the wing as big as possible with that weight restraint.
