Hi Nikos
I had yesterday also problems. [>:] Unfortunately, nothing fixation works. [:@] No messages nothing. [:@]
So, ok
I use the T-Canalizer kit from ZN-Line. (Balsa) Some details can be seen on my Web site. The angle should be 0.5 degrees to the elevator negative.
Messure the Elevator to 0 degrees and the T. Canalizer must be 0.5 degrees down. So the theory. You can read this on every thread. I think this is OK.
That measure is not easy. I have reviewed it and it did fit. I have flown my Synergy until this without the T-C. I open my mouth and I was told to me Wau is this great.
How I build my T-Canalizer.
In Canalizer are two long slits. In this I have glued two M3 Alu-Nuts. On top of the Fuselage ( Overside). I have glued a balsa wood with two holes for the M3 Nuts. And two half pants. CFK/Herex pasted into. The whole thing is screwed and disassembly. The canalizer is then bolted. Sorry I don't have more photos about building.

I am totally impressed by the T-Canalizer. And you certainly.
