REFLECTOR: Vortilons

[Ronnie Brown]

And add one more option - lower winglets.  And it would be nice to get an
"opinion", (Not an official factory recommendation!) for all three
configurations (if there are some things that would make it different for
the three).

1. Std fuse, std wings
2. 173 - Std fuse, Long Wings
3. XL

| OK ... I must ask the obvious question of those at the factory (Scott,
Brenden, etc.) ...
| If you were considering what to do on your very own plane ... what would
you do?
|
| Vortilons?  VGs?  Fences?  All three?  One or the other?
|
| I know that you are reluctant to make general recommendations ... but I am
asking what would YOU do?

| Wow ! So much discussion VG's Vortillons , Trailing edge fences. I
| must be nuts. I have about 150 Hours on my XL-RG I did the test
| flying without anything. It flew great. I painted the airplane and it
| flew better. ( guess I just got better). I have looked at all the
| stuff and am reluctant to make any changes because the wing just
| looks good clean. The airplane gets a little sloppy below 100 knots
| with the gear down. You have to use the rudders to lead the turn and
| the aileron inputs are very deliberate. The problem I have is I am so
| used to it everything feels OK. I plan to install the vortillons and
| see if that makes a big change and then put on some trailing edge
| fences to see if that does anything. I would remove anything that
| effects the top end. I would rather go fast.
| The only other modification I would be looking to do would be to get
| some more heat in the airplane. On a trip back from Kentucky last
| week I was really cold OAT -8C @  FL 015 but the ground speed was 260
| KTS 285 in the decent.
