So what is your impression of flying the SQuiRT with ailerons? Did you end up with the original dihedral or some other amount?

We Arizonans appreciate your new D tube wings

Sanded and ready for skin.

The aileron wing for SQuiRT has less dihedral and a fair amount of differential throw built into the design to reduce (not eliminate) rudder coordination. I still enjoy my 3ch setup, however, the aileron wing has a distinct advantage for cross wind performance. In addition the aileron wing lets me slip in for short field landings.

I think the aileron wing is a good skill builder and can teach the novice a great deal about building, setup, and flying with ailerons.

Lookin' forward to the crosswind and sideslip capabilities added to the SQuiRT.

finally got a chance to fly my squirt w/ the aileron wing today. the squirt has been sitting on the shelf for about 10 days. im always a little scared to maden something.
i had to cut off the ele and rud because they were warped badly, i used the origionals as patterns and i used thicker wood.
first let me say that when i was building the wing i didnt use any ca untill i added the d-tube sheeting.
wow. nothing like a 3d puzzle more like leggos everything locked together
then i tacked everything together.
it flew like a dream. i only ran through one battery it was too windy, i didnt want to push my luck.
hopefully tomarrow it isnt going to be as windy.
love that squirt

I've had my aileron wing for about a week now... but home improvement has trumped building for the time. I have the wing built and I am in the process of covering - it looks like I built a pretty good twist into the wing - I don't know how I didd that, but I'm sure that is was ALL MY FAULT - whatever the reason. I will try to use the covering to straighten it out, if not possible, I will order another. Note - the wires on the GWS pico servos are too short to reach throught the wing, so I'll have to extend them a little.

The Squirt was my first U-build-it and I have really enjoyed it. Yesterday I snuck out for a short flying recess - and promptly flew the squirt into my head. It was one of those really slow and really low passes and I was mesmerized by the approaching plane until I snapped out of it and ducked. I caught the right wheel just above my right ear. Talk about a spin! Picked her up and tossed it back into the sky for more not-quite-so low and slow passes.

Man, do I wish I had this stout Aileron wing for my first trainer...

For anyone having a little warping trouble with tail feathers, don't give up without trying a few tricks. You can use a hot iron on the convex side, you can put em the sun convex side up or you can mist a little water on the concave side. As a cabinetmaker I've used a few of these tricks for hardwood slabs that aren't behaving. Once covered, you can shrink the covering on the concave side to make adjustments. Covering will also do wonders to true up a wing, so don't panic if you have moderate amount of twist.

Depending on how bad the twist is... you can work it out by reaching for the windex... or rubbing alcohol. Wet the wing down and weight it down over a surface that you are certain is flat. Allow to dry overnight. As this is a D-Tube design you're gonna want to focus on wetting that area. Problem is the wet solution will probably shrink the wood spanning the ribs and your D-Tube will slightly scallop in... not a big deal considering the gain of having a flat straight wing.

One more option is to cut free the leading edge this opens the tube.... Re-Glue the leading edge with the wing held flat on your work surface. The Leading edge really locks the wing in. If you glue it on with the wing twisted it will hold that position. Nothing says you have to have a hardwood leading edge. You could easily remove the hard wood, use a sanding block, sand back the LE nice and flat and replace with a rather HARD piece of 3/16" square balsa... then sand it round to match the airfoil. Of course, when you replace the leading edge make certain things are square and flat.

I guess what I am getting at is even if you go for another wing kit you can easily fix a warped structure using some of these tricks.

If the warp is very minor I'd just heat it out with covering...

Hope this helps.
-Bill

Bill - thank you for the building advice. I will try to do you proud with this wing. I'm loving the R/E planform - I have never smiled soooo much while flying.
