Ian=2C
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 a
t standard temp. and pressure)=2C but I was about 3 times above that.And as
you say=2C takeoff is always very swift=2C and landings can take forever u
nless I come in really slow and airbrakes on.How quick is the spin recovery
=2C or will rotation stop when controls are released ? I am a little concer
ned about the small rudder.

Karl=2C It will not be cleared for deliberate spinning=2C as it will still
be classed as non-aerobatic=2C but at least we have now covered the current
ly approved Mass 621 kg (1370 lb)=2C C of G configurations (60.4 to 62.5)
=2C in and out of spin control positions=2C flaps open and closed=2C 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 general
ly good news=2C but as with all Europa A/C=2C the spin is very near the ver
tical so care is needed not to go too far forward with the stick or you can
get into negative =91g=92 situations which can be off putting! With care
during recovery=2C speeds did not go above 105 knots indicated (127 kt lim
it). However=2C we still need to get the increase in mass approved (to at l
east 1450 lb)=2C to be a viable machine=2C 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)=2C from nil wind up the
12 cross wind limit without problems. Regards Ian From: owner-europa-list-s

Subject: Europa-List: MG Spins Hi Terry=2C This is the first note I have se
en about spinning the motorglider. Could you give us details please about r
ecovery 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 withou
t knowing that it would be okay. Cheers=2C Karl > From: iancook_1@btinte
