Title: 5m Turbine Glider Test Flight Post by: xantos on January 27, 2012, 11:38:45 AM Successful test flight yesterday at Aamby Valley airport.
Tech specs. 5 m wingspan all composite glider AUW 15kg wet Power - Wren Supersport 9kg thrust This was one of those PERFECT test flights , 6-8knot headwind ,good Viz, 25deg C - In short couldn't make any more excuses So pushed throttle forward to 1/3 , buddies Nishant and Chaty walked a few steps with the glider holding the wingtips up to prevent from scraping on the ground and in 4 ft I had full controls on ailerons and in few more feet I had lift off !! Few beeps of right ail trim and then explore the flight envelope. Flight envelope is amazing fast with turbine ofcourse but power off all you need to do is push the nose down and she's moves ! Put her into the wind and slowed her to the stall & she slows down beautifully BUT once at the stalling speed she drops the left wing rather desperately. Set up for landing , normal left hand circuit , 2-3 deg dive to keep speed up , no flap fly clean into final and pop the spoilers on short finals about 15ft from the ground. Im absolutely astounded what the spoilers can do ! This is my first experience with spoilers. In the clean config the glider would have otherwise floated the length of the 8000ft runway , stopped almost at my feet ! some more pics coming up - sorry no vid this time Title: Re: 5m Turbine Glider Test Flight Post by: xantos on January 27, 2012, 11:40:32 AM some more pics ---

Title: Re: 5m Turbine Glider Test Flight Post by: Swapnil on January 27, 2012, 01:37:45 PM Yup, I would like to see high-res pics of this beauty too!
Title: Re: 5m Turbine Glider Test Flight Post by: xantos on January 27, 2012, 01:46:45 PM Pics are in RAW format converted to large jpegs in iPhoto but im loosing too much res trying to compress to meet 200kb requirement
Title: Re: 5m Turbine Glider Test Flight Post by: Swapnil on January 27, 2012, 01:51:58 PM I use IrfanView (4.28) to resize (image-> resize/resample) and step down to 800x600 and then in the save-as options for 'jpeg' select quality as 80%. That gives good enough quality with small enough size. 2MB pics can be brought down to 30-100 KB.
