This is the Zesty full airframe. T-Tail with servo and the Zesty wing... the Zesty wing is a little longer, RK40 airfoil, but the same layout as the proven Juicy design. Pushing the design to try to go just a little bit faster. The Juicy has the 3D printed DS record at 225 mph...
Complete STL file set for this 3D printed airframe. Carbon Fiber sold separately.
Can be printed with PLA, PETG, or whatever you want to print it with. In this case heavy and stiff is best... PLA+ is suggested.
- wingspan - 50.5 in (1285mm)
- wing area - 256 sq.in. (1651 cm^2)
- RTF weight - 29-60oz (820g - 1700g)
Extra thick walled wing saddle, radio tray and nose cone.
The Zesty DS is based on the Roughgen and Juicy 3D printable airframes, and is tailored for dynamic soaring. A 10mm Square Carbon main spar and two additional spars make for a stiff wing that can handle boundary layer turbulence and be loaded up with some extra ballast.
Not only does the wing have more carbon / stiffness, so does the fuselage. An extra longeron runs the full fuselage length to bolster the radio tray and tail, and extra carbon can be used in the wing saddle to improve survivability when landing a heavy weight.
See the links page for carbon fiber suppliers and other needed materials.
Sure, a foam combat wing is the best entry level DS trainer. The Roughgen / Juicy might be the best next step. Easy to print, easy to build and inexpensive parts make this airframe a fantasic entry into dynamic soaring something that is efficient enough to pass the 100+ mph without much effort. Flies like a molded plane, but costs less than a foamy.
Pick you wing preference: 2 or 4 servo wing. 2 servo for the ease of build and programing, or 4 servo for separate flaps. The wings are available separately... so you can have both.
The RK40 airfoil is a proven dynamic soaring shape and is good to over 200 mph and more. Other airfoils will be offered, but this airfoil is the go to for DS speed.
This design will continue to be developed and part revisions / updates are included.
