I have found an Aventura II XLR that I will probably buy soon but I can't find any information about it. I don't find any YouTube videos or descriptions about what made them different from other models, have many been built, what should I be looking at if this is a more unique or different model? Are there some unique or difficult aspects that have limited the number made? There is a glass panel from 2007 and some of the info is showing they are no longer upgradable (like the GPS charts, etc.) without upgrading to a newer model. Any info will help since I would like to make a purchase BEFORE heading up to Oshkosh in the next couple weeks.

I'm very interested in learning more about the principles behind the flexing wing ribs and how they should be behaving in flight. I read the earlier post and advice about pushing the upper rib back up before each flight (Jan 2018). Pushing them back up prior to a flight ostensibly will increase the camber on the upper wing surface and seems like it might help the stall speed for the subsequent take off, but once they get stuck down again (e.g., after flying at higher/cruise speed) they'll no longer move back to the position that would give more camber on the upper wing surface and hence the lower stall speed. Are the upper ribs really supposed to be stuck down in this lower/deflected position after a flight? (See picture)

I'm adding ADSB-out (uAvionix echoUAT) and am considering different locations for the transceiver antenna. It's pretty much identical to a standard transponder antenna. Recommended location for these (like with transponders) is on the fuselage belly, which obviously isn't a good choice for an amphib. I'm curious what others have done. What's worked well, what hasn't? Any pictures would be welcome! Thanks!
