(Legacy) Xenos Question

Slow (10 years and counting) Legacy Xenos. Using 912UL (80hp) Rotax. Hopefully first flight this year. A few questions:
- Plan to use the short wingtips almost exclusively. Has anyone calculated the glide ratio (as well as other performance parameters) with the short tips? Fully understand that I will need to do my own flight testing.
- Anyone aware of transition training for the Xenos or at least conventional gear Waiex? Might approach Paul Dye.
- Has anyone converted a Legacy Xenos to center stick. (understand that the lowered seatpan makes this complicated)
Greatly appreciate any input.

Hey Rick! I don’t have any answers for you but welcome to the forum. Training is hard/impossible to come by. But depending on weight and location you may find somebody who will take you flying and get some familiarity.

Hi Rick,
Yes, I have the data from glide tests with short and long wingtips & with & without wheelpants & with cowl flap open or closed. Yes, I spent a week designing and building a cable operated cowl flap for my CAMit 3300 engine (about a 12% improvement in L/D.) I don’t remember without looking at the data what the other differences were. I can send you the xcel files if you like. There was not very much difference. With the long tips, I have about a 20:1 glide with cowl flaps closed and with wheelpants, gear leg upper & lower fairings, etc. I never have achieved the claimed 24:1 that Sonex advertises.
