Hello!
I begin this topic, but I already know it will be very spread out over time!
I bought two Vacuform. The Phönix C.I and UFAG C.I.
That was a few years ago. A few months ago, I bought the two WD on these topics.
I know SIERRA are considered as very good for forms.
But comparing with the plans, I am very pessimistic.
To continue with the series of Phönix, I started the CI.



The fuselage is too short. The engine hood is too approximate. The wings are not bad, unlike UFAG, unusable ....
I decided to redo the wings anyway

.



And tail. These are drafts. I refined half a wing this time.

I hesitate a lot for the fuselage. I wonder if the most "simple" would be to rebuild everything.
I'll do this one, and others that will be easier and faster.
I'll start without stress

A bientôt
Arnaud
