Hi Terry,
This is the first note I have seen about spinning the motorglider. Could you give us details please about recovery and height loss per rotation ? I have been unable to stall mine in level or descending flight and I have been reluctant to force a spin without knowing that it would be okay.
Cheers,
Karl

Terry,
We have just finished the spinning trials in my mono motor glider
after two years of trying to satisfy the LAA (UK) requirements to get a
Permit to Fly, so was very interested in your comments, especially about
blocking of the cooling ducts to improve the LD ratio, do you have any
further details that you can make available? I had the company (Europa) fit
small wing tip wheels to my wings so I can take the outriggers off
completely if I want to go wave flying. Is your machine a mono or Tri-gear?
Best Regards
Ian Cook

Hi Karl,
We have not spun our plane with long wings, that was another participant to this thread.

Karl,
It will not be cleared for deliberate spinning, as it will still be classed as non-aerobatic, but at least we have now covered the currently approved Mass 621 kg (1370 lb), C of G configurations (60.4 to 62.5), in and out of spin control positions, flaps open and closed, wheel up and down cases. The LAA and Europa are still to review all the data and videos so I will not pre-empt their report other than to say it was generally good news, but as with all Europa A/C, the spin is very near the vertical so care is needed not to go too far forward with the stick or you can get into negative ‘g’ situations which can be off putting! With care during recovery, speeds did not go above 105 knots indicated (127 kt limit). However, we still need to get the increase in mass approved (to at least 1450 lb), to be a viable machine, it is currently too limited with the extra wing weight to operate at 1370 lb standard XS limit. Several of the take-off and landing at 1370 lb were completed from a grass strip 400 m by 20 m with 1 degree up slope (290 ft above SL), from nil wind up the 12 cross wind limit without problems.
Regards
Ian

Ian,
Thank you for the useful information. I had done the 1450 pound test flight without a problem. Here we only require a climb test (minimum of 300fpm at standard temp. and pressure), but I was about 3 times above that.
And as you say, takeoff is always very swift, and landings can take forever unless I come in really slow and airbrakes on.
How quick is the spin recovery, or will rotation stop when controls are released ? I am a little concerned about the small rudder.
Karl
