For some reason I'd rather think of myself as a short guy with a long torso than
a tall guy with stubby legs.

To Group:
We have put a 1 hour initial flight test on the wing tip extensions. Flight
was for general flight qualities no specific data was taken. Takeoff roll is
shorter, the landing roll is shorter and final approach speed slower, this
was evident on my 2 landings in which a slip was needed to get down when
flying at the normal approach speed, so after a few hours I am sure we will
figure a new revised approach speed with the tips. Stall speed seems to be
initially 6-8 mph lower than with the standard tips. Climb rate is higher
too. The stick force required is slightly higher with the new tips, although
there is no significant reduction in roll authority or response at high
speed or in slow flight and near stall. No bad habits in the stall so far,
the stall is so slow that you are left waiting for it to happen, and than it
does there is a mild buffet just before but not as much as before so the
next thing will be some yarn on the wing and tip and see what the air is
doing around it.
So long story short the tip flys, and so far are doing what we had hoped.
These tips were installed with nut plates as we know that there are many of
you wishing to install them this way. I think that glassing them on will be
easiest as we did increase the glass thickness on the wing at the attach
point by 2 layers of 10oz , so there is a bit of extra work, if there are to
be glassed on the 2 layer will go over the seem anyways.

Sounds like good news Nick, thanks!
When you have pictures of the installed wing tips, I would like to post them

Your results sound very positive, especially for LSA. Any observation of
effects on top speed or economy? How about roll rate?

I had a chance to view your log today, and its really neat. I hope to
start painting in about two weeks here and hope to get things rolling

Thanks Tex.
I haven't updated my log for a few weeks as my home pc HD went south. I
only have email access from work, but should have it back up so I can update
things shortly. We are at the point where we are ready to schedule
inspection!
I'm very excited and can't wait to get this guy up in the air.
Glad you like the paint scheme. Fell free to copy any ideas you like.
Jim!

Hi All,
Has anyone attempted to embed a trim tab in the ailerons or elevator?
Are there any flutter concerns in doing so?
How are you actuating the flaps, with a dash mounted switch or a stick
mounted one. What stick grips are you using? What functions are you
putting on these stick grips? How have they worked out in flight?
I would like to fly with my right hand on the stick and actuate the
throttle with my left. Have any of you (I know Johnny Thompson has)
created that set up and how does it work?
Thanks.............Bill Applegate, kit #49, Tucson, AZ.
