  • 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.
