Hi Henning

The Ascent is looking great.

My knowledge on F3a biplanes is almost zero but I do have a Miss Wind 50. I'm not sure what the thrust is but with the stab at zero the top wing is -1.5 and bottom +1.8. The incidences of the Ascent look a little confusing to me. It would seem that it will require up elevator to fly level. Looking at the plan although it gives +0.5 on the stab the stab outline looks like it has negative incidence which makes more sense to me. There are also two lines that cross in the centre of the stab. The top line which is just below the LE centre and has the 0.5 over it crosses the bottom line. At the trailing edge both lines are well below the stab TE. Maybe I am looking at it wrong but measuring to the datum the stab is negative.

Keep up the good work.

David
