Hi Lukasz,
Sorry I should have put a post here.
We were at the commemoration celebrations all day.
Unfortunately we had to call it off due to bad weather forecast.
To do the flight we have to ferry to wales ,leave the model with the club there and travel home before it.
The forecast was correct ; 35km headwinds and thunder storms.
The ferry home may have been cancelled.
I did stay in touch with Tom, who prepared a firmware update to use GPS altitude.
We have approx 4 hours of flying on the gluon now.
The GPS altitude seems to work well and in general the Gluon is flying the little Bleriot very well.
We have a high level of confidence in it's ability to do this flight.
30km headwind = 2 hours extra.
The Bleriot is essentially an open structure and not easy to protect from driving rain. - Shower proof maybe - will have to look at that.
The gloun is in the pilots place in a complex foam housing and we are at the limit for weight due to fuel load.
Also the CG has to locate very precisely to work as the fuel load drops. We need the Cg to move a total of 3 to 4 mm forward as the fuel load drops .
There is 1200cc fuel in a model that weighs 3.2kg dry.
Will do this as soon as suits the guys involved and when the weather suits.
