J'espère que tu vas bien!!
I mostly agree with the suggestions made.
I didn't do an access to the instrument panel but will consider it.
I would definitely encourage the gear tower mod. Even with the larger access, it still is tight to get in there, but I have quite large hands...
I'm no engineer so I can't say how it influences the rigidity but I feel confident that with adding a cover held on by screws, the integrity of the assembly should be kept (if not increased?)
The Andair fuel selector is a winner for sure, you will have to make a new bracket and modify slightly the cover.
This is a Duplex model for full fuel return to the tanks:
Grove gear is also highly praised, I ordered the airfoiled model, not received yet though.
Amuse-toi bien !!!
