Drift.

Hi Fred,

That's a difficult one! There are 2 halls and although we were going
to use the bigger 30 metre high one, a large lighting array in the
middle could not be removed. So, we flew in the lower 22 metre site.
This has all the windows blacked out and a barrel vaulted ceiling -
the inside of a concrete structure with a smooth surface.

The problem with this hall was the temp, never below 30 and sometimes
over 40 (well above 100 for you). 6 days of that made it very very
hard work! Lot's of exploding motors, often in flight and the heat
made the drift fearsome so all flights needed several steers at
least. Get too high and hit the roof and the roof geometry and drift
would pull the model downslope quickly, losing altitude fast. It was
often impossible to get a balloon above the model to catch it and
move elsewhere. The bigger hall has a lot of glass including many
bullseye lights in the domed ceiling. Whether this would be better is
unknown - the hall hasn't been test flown yet.

I think by general agreement, the smaller hall is not adequate for
2008 and the big hall must be cleared of obstructions.

None of the above is critical of the organisers. Generally speaking,
they did a fine job but global warming certainly played a part in the
contests this time.

turning the model by the boom and holding it into the drift. Also the
rule clearly states the front of the model, I pole steer a lot by
catching the plane behind the prop just like a balloon steer and have
no problems even at over 30', you let the plane fly onto the pole
just like with a balloon string.
