AD Pure 3 SM

AD Pure 3

I flew the Pure 3 from 90 to 95 all up.
Launching the Pure 3 needs a steady and pressured pull to reach overhead. The lift is immediate.

In the air the brake pressure is on the moderate to hard side and i couldn’t say that the pure 3 is an agile glider but ok. It has less agility and more firm brake pressure than the Peak 4 23 i have here as reference.

In turbulent conditions, the Pure 3 feels more as a block and moves as a whole structure than the Peak 4 does, but needs slightly more active piloting. The climb rate in weak and strong however is very good on the Pure 3, as the glider spring up very quickly inside thermals. Could be one of the best in climbing.

Gliding overall performance seems moderate to ok, for a 2 liner D glider
(if loaded at top) .

At 93 all up the trim speed resembles the LM6 one.
At full bar i could see an increase of 13 km/h at 600 ASL. I think 96, 97 would give better results.
Gliding on the Pure 3 with bar and controlling it with the B riser is very efficient in moderate turbulence. In strong turbulence, a more pilot adaptation is needed to keep the glider overhead as the B riser pull has a stop limiter. But it’s really efficient in moderate stuff !

Big ears are stable ! Efficient and reopen quickly.
Conclusion: My last flown D gliders this year were the King S , LM6 MS, Peak 4 23. The Pure 3 felt that it needs slightly more active piloting than those three only in some quite turbulent conditions. The agility is moderate to low compared to those three above which lead me to think that it needs more pilot adaptation (getting use to it) to control it better.
 In moderate turbulence, it felt more as a block overhead. I think this glider needs some “exoceat” “XR7”  Type harness and a good pilot pushing along good lift lines.
