5 Tube-Frame Ultralight Aircraft Plans
Plans are for full size aircraft and include:
- ‘The Cabin’ Aircraft Plans
- Fike Model D
- Heath LN Parasol Aircraft Plans

Metal tube airframes are strong, lightweight and repairable. Aluminium tube can be assembled with bolts and rivets (no welding required for some designs), while steel tube frames use TIG or gas welding.
