| The instructions that came with my Waco 550 V-tail from Weston
Aerodesign simply state- "Rake the tail about 5-10 degrees".
It certainly did not sound like it was critical.

That's Frank Weston! If you have seen how poorly some of
his leading edges look you know what I'm talking about. Frank
has a really relaxed attitude about a lot of things (other than
customers!).

| 1475.3 | Rake?? | RANGER::PITONIAK | | Thu Dec 03 1992 07:25 | 9 |
| Thanks for the response,
Could you define rake? I am assuming it means taking the centerline of
the tail out of alighnment with the fuselage, is this true.
(That would be a negatine amgle of attack; correct?)
thanks,

| 1475.4 | Rake 'Reik' - noun, angle ... | MR4DEC::ANKER | Anker Berg-Sonne | Thu Dec 03 1992 08:54 | 6 |
| Re: <<< Note 1475.3 by RANGER::PITONIAK >>>
Rake is the angle from the vertical of the fin (how much
it leans backwards).

| I believe the V-tail plane should be at 90 degrees to the fuselage
(0 degrees incidence).

| 1475.7 | Setting V-tail incidence? | UNYEM::BLUMJ | | Mon Jan 31 1994 10:09 | 19 |
| In a recent article British F3B flyer Nic Wright expounds on the
merits of the V-tail specifically relating to his EV-1 design.
Whether this is just a fad that has been reignited by the success
of the Kowalski Bros.(German) Spark design, or "the new wave" of
performance gliders remains to be seen.
Computer radios have simplified the mechanics of V-tail mixing, however
I have questions about mounting the tail in relation to the wing.
In the past I have used a Robart incidence meter to set my T-tails.
This is relatively simple, with wing seating tape acting to shim the
stab into the proper position.
Can the incidence meter be used to set a V-tail? If not does anyone
have any suggestions on setting the incidence between wing and V-tail?
Thanks,
Jim

| 1475.8 | Vee Tails.. | SHIPS::HORNBY_T | Soarers are rarely Silent | Tue Feb 01 1994 08:29 | 17 |
| Jim,
Dave Woods and Greg Lewis who developed the Parabola and have done
very well in the F3F league here in the UK, have been experimenting
with 'V' tail configurations in the 60" pylon class. They use the
moulded wing tip sections only and join them together for this smaller
version. The V tail is fixed type (not all moving) which I believe is
Assembled and lined up in two stages. The first connects the two pieces
of the fixed vee together and then these, as an assembly (already
aligned) are offered onto the moulded fuselage.
I'm note sure of the detail but will check with my friend who has
assembled 2 prototypes for Greg. However I believe the trick is in the
two stages, I think he has a long, firm piece of piano wire which sits
in the bottom of the Vee to aline both direction and incidence when
assemling the 2nd stage.

| re: -1
Thanks Trevor, any information on this is appreciated. That is the
nicest thing about the full flying stab, it is so easy to set the
correct incidence.
I am mostly interested in the V-tail because they are much less
subject to damage on those less than perfect, fast landings.

Jim

| One of the V-tails I have is a full flying type. It has a small
horizontal centersection that encloses the pivot.
