RE: Build Thread: New QQ-Yak 54 101", DA-85
Problem is even though we recommend DA-85 and test flew it with that engine, people out there have variety of engines that may be wanting to use. We actually have first hand experience on this. Python came already drilled and blind nuts installed for DA100 and 3W106 but many complained that they had to pop the t-nuts and plug the holes because it didn't fit their engine of choice. It's hard to satisfy everyone as all of us have set up our planes differently.
On the anti-rotation pins, it only took me 10 minutes to install them and I know I have enough glue where it should be. Although you have a point!
