Complete STL file set for this 3D printed airframe. Can be printed with PLA, PETG, Light Weight foaming PLA (Colorfabb/E-Sun), or Low Density PLA (Polymaker PLA-LW). wingspan - 48.9 in (1243mm) wing area - 234 sq.in. (1508 cm²) RTF weight - 15-27oz (440-770g) The Roughgen is a 3D printable airframe, based on many molded slope racing / performance gliders from the past 30 years. The Roughgen Version2 file set adds the most popular option of the removable wing with the selection of wing airfoil, type and size. The Roughgen file set features the Cross Tail Design. All other tail options can still be used with this file set. Recommended wing - 1.2M RG15 2 Servo - Bread from F3F competition, the RG15 airfoil is a known performer with a huge speed range and excels many conditions from light lift to booming thermals. With a 1.2m wingspan is small enough to easily fit just about anywhere, but big enough to be seen easily even at a distance. The design was specialty formulated to deal with rough landings in bushes and rocky areas with a reinforced leading edge and features to hold carbon support. Flies like a molded plane, but you print the parts. Print extras for repairs or print multiple copies. 2+ complete sets can be printed from 1kg of material. This is the simplest combination for be best performance. You can select one of the other wing options, see the airfoils and wings page for a complete explanation of the different types. All wings fit all fuses, so upgrading later or trying additional wing type is easy. Designed to be printed in any type of material. Carbon reinforcement is recommended but not necessary. Less than 20 individual pieces. This is the 3 servo version: aileron left/flap, aileron/flap right, and elevator. Different tail, wing and power pods nose variations available separately. What do you get: STL files for each part Building instructions Print Settings for Prusa/Bambu/Orca, Cura and Simplify3D Update - v3c - minor file updates for better printing and better building Update - v3b - update files for foaming and pre-foamed PLA printing Update - v3 - update wing and fin parts to "Perimeter Before Inner" design Update - v2c - improved tail surfaces for larger area, big control surfaces, longer control horn and straighter pushrod. Added extra carbon channels in wing saddle for more carbon support if desired. Update - v2b - faster printing fuse and tail files for Cura Slicer, assembly features for vertical tail added Update - v2 - Roughgen v2 Fuse and wing as separate.

Complete STL file set for this 3D printed airframe. This is the same file set as the Roughgen V2, but with the V-Tail as standard. Can be printed with PLA, PETG, Light Weight foaming PLA (Colorfabb/E-Sun), or Low Density PLA (Polymaker PLA-LW). wingspan - 48.9 in (1243mm) wing area - 234 sq.in. (1508 cm²) RTF weight - 11-27oz (370-770g) The Pika is the V-Tail glider design based on many popular F3F slope racers. This 3D printed airframe is capable of the flight characteristics only found in molded, far more expensive designs. The Pika has the performance and durability of the Roughgen line where carbon reinforcements are uses in the right places, and the printed parts are suited to survive harsh landing areas. The Pika comes standard with a detachable wing system and choice of wing type. All other tail options can still be used with this file set. Bread from F3F competition, the RG15 airfoil is a known performer with a huge speed range and excels many conditions from light lift to booming thermals. With a 1.2m wingspan is small enough to easily fit just about anywhere, but big enough to be seen easily even at a distance.

This is the simplest combination for be best performance. You can select one wing options, see the airfoils and wings page for a complete explanation of the different types. All wings fit all fuses, so upgrading later or trying additional wing type is easy. Additional wing designs can be purchase separately and all will fit this model. Designed to be printed in any type of material. Carbon reinforcement is highly recommended but not necessary. Less than 20 individual pieces. This V-Tail can be built with 1 servo elevator control for ease of set up and use., or an additional servo can be used for Ruddervators (complete V-Tail controls) . Different tail, wing and power pods nose variations available separately. Additional parts required to finish this airframe. See instructions. What do you get: STL files for each part Building instructions Print Settings for Prusa/Bambu/Orca, Cura and Simplify3D Update - v3c - some additional minor part updates for better printing and building Update - v3b - update files for foaming and pre-foamed PLA printing Update - v3 - update wing and fin parts to "Perimeter Before Inner" design Update - v2c - improved tail surfaces for larger area, big control surfaces.

Update - v2b - fuselage and tail fin update for faster printing in Cura, v-tail pushrod sheath glue access improved Update - v1 - initial release

Complete STL file set for this 3D printed airframe. This airframe includes the power pod, t-tail and wing choice. Can be printed with PLA, PETG, Light Weight foaming PLA (Colorfabb/E-Sun), or Low Density PLA (Polymaker PLA-LW). wingspan - 48.9 in (1243mm) wing area - 234 sq.in. (1508 cm²) RTF weight - 17-30oz (500-850g) The Igneous is a 3D printable airframe, based on F5B racing / performance gliders from the past 30 years. The Igneous is the T-Tail version of the Roughgen and includes the Power Pod. The Instructions have been tailored for building this powered t-tail variant. The slope nose version is also included and other tail options can be used with this set. Recommended wing - The MH32 4 Servo - this wing was designed to match well with the power system, with a higher lift curve for faster climbs and longer thermalling. With a hotter motor this wing can still show great speed and does well on the slope... a good all around wing. This wing design also uses a 7mm spar tube (instead of 6mm) offering the same stiffness as a solid 6mm spar, but almost haft the weight. This pared with the Polymaker LW-PLA makes for a light weight but stiff wing for long flights and amazing performance. You can select one of the other wing options, see the airfoils and wings page for a complete explanation of the different types. All wings fit all fuses, so upgrading later or trying additional wing type is easy. Designed to be printed in any type of material. Carbon reinforcement is recommended but not necessary. Printing ~ 20 individual pieces makes a whole airframe. This T-Tail version does not use a rudder, elevator only. Different tail, wing and power pods nose variations available separately. What do you get: STL files for each part Building instructions Print Settings for Prusa/Bambu/Orca, and Simplify3D, older Cura Update - v3c - fuse tail changes for better pushrod path and better printing, added LW power pod supplement for foaming LW-PLA. Update - v3b - update files for foaming and pre-foamed PLA printing Update - v3a - update wing and fin parts to "Perimeter Before Inner" design Update - V3 - this is just an update to the power pod nose and wing saddle. Servo mounting and vent are now part of the wing saddle part. Added support carbon channels to match the upper wing saddle carbon to add strength for higher power motor systems. Update - v2c - improved tail surfaces for larger area, big control surfaces, longer control horn and straighter pushrod. Added extra carbon channels in wing saddle for more carbon support if desired. Update - v2b - faster printing fuse and tail files for Cura Slicer, assembly features for vertical tail added Update - v2 - Roughgen v2 Fuse and wing as separate.
