Tony gets to soar the T21B on Thursday when the conditions were good enough to find a thermal or three. You need goggles against the blast behind the Cub, but not to soar.
The English are:
and we all like to bring a bit of the England we know
where-ever we go.
But many countries
are not entirely compatible with English sensibilities
and so it's difficult to get a pint of real ale in an
arab country, and in Thailand it's difficult to fly one's
vintage glider and one's Tiger Moth.
The 52 inch pitch metal prop was replaced by a 44 inch pitch wooden propeller, but the rate of climb did not improve much. This is a broad chord propeller; perhaps it's more effective at low towing speeds.
Tony is responsible for bringing in the T21B and the dh82a to Thailand. It's great that he is able to take part in the gliding he'd worked so hard to bring to Thailand
My job is to tow the Sedbergh at it's ideal speed; 55mph! I used one stage of flap and testing seems to indicate this gives a better rate of climb at 55 mph than with no flaps.
The takeoff was with a 2 to 3 knot tailwind, but the options if anything goes wrong are better in this direction (16).
The grass was used for landing both the tug and the glider. This meant coming in high and slow then steep and 55 mph IAS in the tug to avoid snagging the tow rope on the fence which could have led to a very short landing!
Tony's flight was
delayed 15 minutes due to traffic at Chiang Mai
International, and rather than being allowed to climb to
3,000 feet ASL (Nok is 988 feet ASL) we were limited to
2,000 feet so regretfully I waggled the wings and the
pilot experience has been an interesting one.
The takeoff run is longer and the Cub gets airborne at 45
mph or so, then I accelerated (so to speak!) to 55 mph to
climb (in a fashion).
I did four tows on
Wednesday, and five tows on Thursday. Six tows were to
3,000 feet QNH, 2,000 feet AGL and these took between
nine minutes and fifteen minutes. Most were at nine
12th and 13th February 2013
On Tuesday 12th
February I did five tows and Yves did two.
This past week has
been a military execise with USAF KC130 Hercules aircraft
flying around at all levels.
