Eugene,
1) How long does it take to deploy your flaps?
2) Where did you get the electric screw & what's the weight?
3) Where did you get the plastic angle stock?
4) Did you do a before & after comparison of your wing tip mod?
Thanks,
Richard Swiderski

Hey Rich,
I knew someone would ask me that. 
I lucked out when a local machine shop went out business that used
these servos for a project they worked on. I salvaged several from a
bunch of stuff they were discarding. They were slightly used but like
new.
I believe you can get them from an industrial supply place like
Grainger but they may be a little salty. I could check for you. I'll
also post an exact weight but they are very light.
I did not time the full stroke but they are very similar to speed of
152/172 Cessna flaps, perhaps a bit faster.
The plastic angle is a corner wall protector strip you can get in the
Paint and Wall Paper section of a Home Depot or most any homebuilder
supply place. They come in 8 lengths with stick on adhesive for only
a coupla bucks. Of course the adhesive is on the wrong side for our
use. I simply removed the tape, cut them to little inch and a
quarter pieces, put them all in a jar with gasoline for an hour or
two to dissolve the sticky adhesive then wiped them clean with a
towel and cut the angle with a scissors. Make half of them left and
half of them right. Stick em on with a dab of clear RTV silicone.
Cost ya less then 10 bucks.
As far as the wing tip mods, I have had several Kolb models with the
standard wing tip. It is rather tedious to get the compound bend on
the bow tube just right to do the tip modification. The difference
in handling is that the mod now gives some definite roll control with
rudder only which the standard Kolb tip configuration does not
provide. All standard Kolb models are roll unstable with rudder
control only. I like the looks of it and the roll control but would
I encourage others to try the mod? Probably not.
The flaps and the VGs are what make me a happy camper with my
Firestar mods.
