Last weekend at the Last Chance Aerotow I had my Blanik, which has telemetry, and it reported I detached from tow at near 1800' and within a few minutes I got into a hat sucker and went to 2606' AGL. It was a tiny speck and I bailed out of the thermal. Great flying glider.

My first day of flying the plane originally only lasted two flights so I was not able to sort it out to know if I had right. I have it set right now at 75mm. Any feedback will be greatly appreciated.

Thanks,

In testing I went as far back as 90mm, aircraft flew ok however would not recover from a spin. C of G at 20-30mm from the LE the aircraft recovered instantly from a spin.

I know you have to ad more nose weight (4lbs approx) to reach the recommended C of G however it's is there for a reason, plus teh extra pound you save doesn't really add much to the models performance, it actually likes the weight.

You can run further back that recommended if you don't plan on doing aerobatics howevr personally I feel the forward position makes It a better handling aircraft,

C of G is like salt, add to taste however too much will hurt you :-).

Wow, I'm amazed at the usable CG range of this sailplane. We're talking in the range of 3". Is there something about the configuration of this plane, wing plan, etc. that will tolerate such a broad range?

TIA,

Steve

I ended up moving my CG further Forward than my original setting after reading Len's comments and am somewhere around 60mm now and my plane recovers very well from a spin. I did not try any Flat or Inverted Flat Spins but did spin it on multiple occasions and it recovered very quickly. Not at all doubting what has been said above by Team Horizon just giving my two cents worth after putting my Blanik through the paces at our last Aerotow. Of course a lot of my Aerobatics look more like a Drunk Pilot Routine than real Aerobatics.

Thanks,


Pat
