Hi Xantos!
Actually I'm very pleased with the performance - sorry if I wasn't clear. These low drag gliders go like missiles once you get the speed up. It's just the start you could use some more power - especially if you are flying from a short field. I try to get a video next time
5m Paritech DG-303 and Wren 44 Gold should be a perfect match. With a Supersport it would of course be ballistic...but I would put the 44 in it
