A: If you couldn’t even get it off the ground, that’s a “You” problem. As others have stated mostly likely you had the classic, not modern flight model enabled.
B: You are posting about your experience with 0.10 after the dramatically improved 0.20 was released. Maybe one could quibble that 0.10 wasn’t ready for release, but 0.20 came very quickly and the feedback gained from people trying 0.10 really improved 0.20.
It’s still not perfect, but it’s dramatic how many significant things were improved in about a week after initial release. It was never marketed as a study level aircraft. It IS a LOT of fun in it’s current state. I have no regrets buying it and I know it’s going to continue to improve. There’s two other updates planned in the coming month, not to mentioned the great mods people have been doing.
This “review” seems based on a very poor understanding and likely some mistakes on the reviewer’s part and borders on slander, defamation.
