Here is what I have heard...

The GP14 has evolved significantly in several key design areas since the initial design was completed. This required a cascading array of part and system design changes. And that process has understandably taken som extra time.

For example motor technology advancements allowed them to increase the motor size from 15-25kw (a whopping 66% increase in power!) with nearly the same form factor and minimal weight increase. This obviously should significantly improve expected performance, efficiency and especially high altitude launch performance. But maximizing the performance and efficiency of the newer more powerful motor demanded larger propellers and the entire motor retraction system (pillar, actuation, controllers, propellers, batteries and wing battery compartments, etc.) needed to be modified, enlarged and strengthened.

Other significant improvements have been made although I'm not certain what they are exactly.

All this change has (understandably IMO) pushed back early orders 6-12 months from initial delivery estimates. Unfortunate for anxiously waiting buyers but not without increased value or justification. This is not simply a case of being behind or "late." They are making significant and intelligent improvements and trying to do this right. I understand that the first gliders will be in the USA next spring and they we're initially expected this fall.

Not to be a complete GP14 cheerleader (I do have some skepticism), however, I do think a 45:1, extremely high performance electric self launch glider (HUGE at this price point) has the potential to be a true game changer. 45:1+ is more than enough performance for me personally. IF the 13.5m class was to catch on, the idea of paying double for 15/18m for an extra 5 to (perhaps) 7 LD points (at low speeds) is fairly difficult to justify.
