Those interested in TG fairings
I flew my TG with and without the fairings in different combinations.
I am sure that the fairings on the landing gear struts are by fare the most
beneficial.
I think they made a 5 MPH difference by themselves. They are not easy
to fit the way the factory kit does it. And I tried to do it better and failed.
New fairings for the landing gear struts will be another project I might do.
(easier to install and smoother trailing edge.)
I did make small fillet type fairing at the intersection of the landing gear
strut
fairing and the fuse and the wheel pant. They should have been bigger I suppose,
but bigger would have been much harder to do. Sorry my web pictures don't
show much of that. (there is another to-do)
Just my 2 cents worth.

Hi Fred
Do you think that fairings around the flap hinges are beneficial? I have
made them but am undecided abut mounting them. The frontal area of the
hinges isn't much and maybe the fairings will be adverse due to more skin
friction?

A definitive answer is either a) better; b) worse, or c) no change. :-) It
actually may be possible that interference drag is increased, if you have a
gear leg fairing. What I did is make an aerodynamic "spat" which seals
everything and mitigates interference drag. Latter BTW is the effect of,
especially with an acute angle of the gear leg, airflows of different
velocities mixing and going turbulent at the junction.
The "spat" the airframe manufacturers design here is probably by eye. It's
so commonly that they may just assume the effect is, net, "proverse."
