I am writing this as a member of the AMA Contest Board as well as a member of the subcommittee noted in section 16.1.2.a.6 (a). The four members representing this group are: Dan Kane, Lloyd Burnham, Bob Brogdon and Duane Gall. We have communicated with both Jim Allen (AMA Contest Board Chairman) and...

Hey Danny, Bill Hauth from the Buffalo Crew. The Printed Parts came out way better than Expected, Lighter than the Vacuum Formed and much less work. My intent was to make a plug but they turn out so well it was like why bother. We had a great time racing with you guys last year. Nice! Looks fantast...

A rule change occurred and made this version obsolete. Therefore, once legal always legal does not apply. It does not meet the current set of rules.

Note to anyone interested, this is a foam wing airplane. This model was built prior to the rules for Q40 to becoming stable. A couple issues prevent this from being legal for modern Q40. 1. It doesn’t have the normal bent leading Edge (knee) at the root. In the early days we followed the lead of the...

Wing cont: After the wing sheeting has dried, I trim and sand the wing in preparation of the LE, tips and Aileron hinge line. First assemble the tips. I use 3 pcs of 3/16" balsa sandwiched with a layer of 1/16" balsa. The order is one pc of 3/16" then 1/16" and finally two layers on top. When assemb...

I have added a couple of build threads in the "Building Tips" section of the forums. I am interested to see finished EF-1's. Add pictures of your finished airplanes please!

AWESOME!

Who are you?

Lastly, if you haven't gotten too far, I would add some right thrust 1-2 degrees. When Jerry and I designed this one we hadn't learned our lesson.

Wing cont:

Someone had asked to clarify the taper I add to the bottom sheeting at the TE. I have included pictures of the actual part as well as a small detail from the plans. Hope this helps.

This is my original Miss Foxy Lady. I built and painted it for Rick, way back. Foam wing, glassed. I built one for Knepper at the same time.

Have him reach out to me. Interested to know what he wants to get for it.

Sheeting a foam wing cont: The next series of photos will show how I prepare sheeting and sheet the wing. You will need 8 pcs of 1/16" X 4" x 36" balsa to sheet a full wing. Yes you will have some scrap. I use a full width sheet along the LE, a second sheet along the TE trimmed to mate with the LE a...

Sheeting a foam wing cont:

(DELETE DUPLICATE POST)

The next series of photos and text represent the process for sheeting a set of foam wings for an EF-1 racer. In this example I use Gorilla Glue. However, if you wish to use epoxy it is exactly the same process. To start I assemble the end of the joiner tube supports. Each panel receives a 3/16" bals...

MFL cont: One scary task is drilling pilot holes for landing gear. Scary, because if you have ever done it, you probably drilled through the top skin. Yep, I have been there did it. SO, I created a 3D printed drill block to act as a drill stop and place the holes in the proper place. I use a #49 dri...

MFL cont: The following set of pictures show the process I use for servo tray assembly and installation: I assemble the supplied servo tray by adding balsa support to the back side. Two long strips of 1/4" triangle stock are glued to the bottom of the tray along the long sides to provide a larger gl...
