Hi Bert, yes it's the first spacewalker from seagull of year 1999 I think.
Wingspan is 160cm, and normally it's for a 52 fs.
I hope my 61 fs converted is enough, if not I will change for the 91 fs.



The solenoid controller from you never failed, but the others I make with seeeduino Xiao failed randomly after a storage, I don't know why.

My air bleed valve :




Engine test tomorrow if the weather is ok.
