Glad to hear Dave and Francine got a visit/flight in and a good kick in the butt to get back to work on their Elite!!!
Cheers,

G'day Bob !
How much $$$ are we talking for these wizz bang tips ?
and please elaborate on the "Angus McKenzie STOL Kit" thingies
(I am VERY happy with our Rebel ... but anything that improves things is always worth looking at ! :-)
I seem to remember that some have stated that the wing vortices generators have detracted from their Rebels' performance .... yes ?
Are Angus' ones different / better ?
Also ..... I have fitted a SCOTT 3400 tailwheel , which has improved ground handling immensely .... but I sometimes get HORRENDOUS tailwheel shimmy upon landing (mainly / always on tar) .... I suspect it has something to do with the angle of the wheel / pivot point in relation to the vertical (which it ISN'T ... as it is laying forward somewhat)
I suspect that the pivot shaft should be more vertical , even, perhaps laid rearwards to stop this effect ... any ideas guys !?!?!
What do you reckon Wayne ?

PS Dave & Francine Ricker are happy campers ..... I took 'em for a quick blatt in our REBEL last Friday ....
there's talk of going home & getting stuck into their ELITE !----- Original Message -----

Hi everybody !
As most of you know, when Dave Fife made the first set of
his Hoerner wing tips for the Rebel, he and Curt Martin fitted them
to Curt's Rebel and did a thorough and scientific study of their
effects on performance. They flew a full series of tests, measuring
takeoff distance, speeds in 2 directions, checked with GPS, etc.
They then landed, changed to the new tips, added fuel to be the
same weight as the first tests, and flew them all over again.
They found a reduction in takeoff distance of more than 20%,
and a couple of mph increase in cruise, and a couple of mph reduction
in stall speed. The strongest comment was how much the tips improved
the low speed controllability and feel. Several Rebels near us
have reported similar results, as well as excellent quality and
good fit of the tips (combined with Dave's tail tips, a savings of
over 60 hours in build time was a nice bonus !)
--------------------------------------------
This is a very delayed, totally UN-scientific flight test
report on my Rebel with the Fife Hoerner tips installed. I put them
on over 2 months ago, and flew them out of a grass strip for the
first flight. Here are my comments and observations:
Wheeeeee !!! Yaaaaahooooooo !!!
She got light on her wheels MUCH sooner than before,
and climbed like the proverbial homesick angel !!! A VERY noticeable
improvement. The approach and landing showed a marked improvement
in speed control - it was easier to peg the speed exactly where
I wanted it. I like them !
---------------------------------------------
Well, that's it, so far. Next I'm going to add the
Angus McKenzie STOL kit (full length wing cuff & fences), on my
way to the ultimate hot-rod Rebel !! Should have her painted
soon, too - so she'll be all ready for the big Ramble next year.
Hope you can join us for at least part of the trip !!
