GP 14 Update and Video of Innovative Motor Deployment System for GP14 E Motorglider

Hello All:

While progress has not been as quick as we had hoped for, plans are moving forward to take the GP 14 E Motorglider to first flight very early in the new year and then for first customer deliveries soon after just in time for the beginning of the European racing calendar.

For a taste of what is to come, please have a look at the two links below for "first Look" at the innovative pylon/motor deployment system for this new motorglider in the 13.5 Meter Class.

- Quick Deployment (@ 5 seconds to deployment and power on)
- Minimal Deployed Drag (Pre-start/Post-shutdown)
- No Aligning of the Prop for Quick Stowage (@5 seconds to full retraction from power off)

Pretty cool!

The batteries will be in the wings or in the fuselage?

The battery packs will be located in the wings and connected for easy removal for charging separate from the glider should that be required.

What is the the duration of the batteries?

....and self-launch or just sustainer?

Tim, Do you have a price list? Will there be any sales presence at the SSA Convention?

The published masses of E-model are just not realistic. GP website says 135 kg empty weight for pure glider and 170 kg for electric one. Even production glider mass is bound to be higher than specified (it invariably is). Current FES installations with 4 kWh batteries weigh 70-75 kg extra with over 30 kg for batteries alone. How an earth GP is going to pull of this feat, doing the whole installation with 35kg weight penalty? FES installations have very little structure for motor/propeller, whereas GP uses complex mast (which looks nice BTW) and doors. It seems quite clear that to participate 13.5m comp you would have to strip pretty much everything from GP-E.

Where do you get 75 kg for FES weight? I see 45 kg on the FES website.

That's pretty consistently the difference in empty weight when comparing FES-equipped glider to similar pure glider. Check LAK-17B for example.
