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)

• 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.
