Human: Flight video:\r\nhttps://www.youtube.com/watch?v=G9AawZxe_DU \r\n\r\nThe Flybear FX707 is a large, reasonably priced, EPO free-flight glider that I purchased for my kids and an RC conversion project.\r\n\r\nI designed the STL files for the motor mount and pylon. The 1704 size motor used in this project was 'borrowed' from a quadcopter drone, paired with a 5030 3 blade prop.\r\n\r\nThe RC conversion is very simple, utilizing 2x 9g servos and some depron foam for the rudder and elevator. Note that polyhedral has been provided to the wings by scoring the top of each bend, filling with hot-glue, and then bending up to create a steeper angle. Each wing joint has been fibre taped, as well as the entire wing on the leading edge and the top and bottom. This polyhedral is necessary for rudder/elevator control.\r\n\r\nThe pylon fin and mount are epoxied together. A slit was cut in the fuselage, centered behind the cockpit to accommodate the fin. Position the fin with less downthrust than I have done with mine. If I were to do this again, I would aim for a more straight thrust line as some down-pitch has been experienced on high throttle.\r\n\r\nA 2 cell 1000mAh lipo battery is used in this project. With the canopy and fuselage front hollowed out to accommodate the receiver and battery, the CoG matches the original free-flight position (which is surprisingly far back, but flies very well).\r\n\r\nThe total flying weight of the plane is 284g.\r\n\r\nBanggood link: https://www.banggood.com/Flybear-FX707-Hand-Throwing-RC-Airplane-EPP-1200mm-Wingspan-Aircraft-Fixed-Wing-Plane-KIT-for-DIY-p-1558739.html?cur_warehouse=CN\r\n\r\nGoogle 'fx707 glider' to find the best price.
