Rolling, loopings and flying on the back is great.Īlso, I didn't change the motor axis angle after several flights as it seemed all well. During first flight almost no trimming was required and the plane flys very smooth. The batterie is located in a manner to balance the plane exactly (1/3 rule for the location of the center of gravity). I didn't apply down thrust (Motorsturz) or lateral pull (Seitenzug) (angle between the motor and the plane longitudinal axis) for the installation of the motor for the first flight. In the end 13 x 6" remained on the plane as it`s the best thrust for acrobatics with a flight time of about 7-8 minutes (medium to full speed). To decide for the best power train configuration I have drawn a spider diagram with the axis "LiPo Cell numbers", "mAh", "Flight time", "efficiency factor", "power per kg" (see picture above). 13 x 6", thrust 100% LiPo charge = 1,90kg // 36% Li-Po charge = 1,50kg ->used for first flight to have enough power 13 x 8" propeller, thrust measured with 100% LiPo charge = 1,55kg // 36% Li-Po charge = 1,35kg I have calculated (with ) and tested following drive trains: Be aware too much heat can destroy your Depron creation. So I heated up the twisted wing tip with two hair dryers (one on each side) and applied some careful manual force. To plank the wing is easy with contact adhesive but once stick, you cannot move/correct the parts anymore! This resulted in a slightly twisted wing in my case. Test the deflection of your wing before and after laminating. To stiffen the structure of the wing (force path between landing gear and fuselage) I have laminated further "magic black hair" (carbon fiber roving) in DIAGONAL orientation. Instead of carbon fiber tubes I used carbon fiber profiles of 6x0.5mm which are lighter, cheaper and stronger. W2 is partially made of ply wood to accommodate the retract landing gear. The order of profiles of my wing is from center to outboard: W1, W0, W2, W2 (yes twice), W3 etc. Need your own NACA? Search in the net for "NACA Generator" and scale it to your needs. The following instruction is about the wing building. To remove a keyword just delete it from the search field, please remove it entirely or the search results will not be so good.As I wanted a curved wing with retractable landing gear, I started from scratch and designed my own one. Each plan will contain the keywords you choose and the plans descriptions will not be searched. When you pick keywords from the panel above you are asking the system to return you the plans that contain those keywords.
Pick only one from each group and keep in mind that we are in the process of editing all the plans so only the plans already edited will show up.Īs plans are edited the keywords above are attributed to them.
