.4mm ply sheeting should have stopped at base rib 1F not, 2F.

Re: Falke T-61A Cliff Charlesworth Plans.
It might be worth noting that, in common with most Scheibe motorgliders, the crank of the TE for the first few ribs at the wing root means that the wing root has a negative AOA compared to the rest of the wing. (I have always assumed that this allows the the TE to sit flush with the fuselage, rather than dangling below it) So, when assessing decalage, it's best to put the meter outboard of the TE crank...

Re: Falke T-61A Cliff Charlesworth Plans.
Thanks, guys. Sorry for not replying sooner. I don't get email notifications from this forum.
I'm not sure what you're getting at, Cliff. But thanks.
Hi Chris. What I think I get from your answer, is that I should ignore the datum line and set the decalage by zeroing my meter on the wing - outboard of the crank (for obvious reasons), then measuring the horizontal stabiliser.
Cheers

Max, why not just make the seat for the tailplane to the shape shown on the plan and trust Cliff C. to have drawn it right? I certainly don't remember confusing myself by trying to measure decalage angles when building mine - sometimes, as they say, ignorance is bliss!

Re: Falke T-61A Cliff Charlesworth Plans.
Hi Trevor
I completely misread the plans.
I had no idea that F1 was supposed to be part of the fin. I thought that it is glued to the fuselage as a lower support for the fin.
It wasn't until I went back to the prototype photos that things didn't add up.
I'm sure that I can work around it. I've had to do it a few times already.
I like to think of it as character building.
Cheers

Re: Falke T-61A Cliff Charlesworth Plans.
Cliff went to the trouble of writing the incidence on the plan, so I thought I'd better check it.
I'm going to need a bit of extra weight in the tail to balance the speakers.
Cheers

Cliffs plans have been built from for many years without issue!
