In fact, we believe this number is conservative. We estimated the building time based on the first TUNDRA being assembled by an aircraft technician in approximately 650 hours.
Furthermore, what we are seeing now with customers building their TUNDRA is that they are all well within that timeframe. With all the parts (spars, ribs, skins, everything) being pre-cut and pre-bent and with every single hole pre-punched, the TUNDRA is not a building project but an assembly project. The assembly manual and the 3D technical drawings supplied with the kit are also helpful in making this timeframe an easy target.
