(This glider was on display at the 2016 SSA Convention in Greenville, SC)

Is this the PSR unit or a US development?

One look at who is test flying it would be a dead giveaway!

I looked at the PSR retrofit a couple of years ago and thought it of limited use in mountainous terrain. The Arcus will be operating in mountainous terrain.

If I did the math right, roughly 5 gallons for a launch from 6k to 10k. Just need capacity for 10 gallons.. ideally optional up to 15 gallons and its a SLMG with good range for self retrieve.

Names not familiar to me. Is there any chance that this could ever be a certified aircraft in Europe?

YouTube with audio please. Will it fit DB?

Sorry, but I deleted the original post. Apparently I jumped the gun on making this public. As soon as more data are collected and some permissions are granted, we will do a press release with videos, photos and actual analysis of climb and cruise performance, along with fuel consumption numbers.

It's USENET, you can't delete anything... (Google Groups may give you the illusion you can, but you can't).
