Reenginered Ringmaster wing looks strong...but is it Army Strong?

Hey yall. Im currently building RSM's Ringmaster kit. Very nice kit, but I only harbor one concern, and that would be the new leading and trailing edge. For the uninitiated, the solid leading edge was replaced with 3-1/8" top, bottom, and front sheeting, and the trailing edge with 2-1/16" sheet. I imagine one just has to be EXTREMELY careful that the leading edge is solid...but there is almost no wood joining the ribs to the trailing edge, and Im worried about the integrity of this here wing.

Any insight/hits/suggestions?

Sean: I built one of the first prototypes of the RSM kit. That one had the solid LE but did use the two x 1/16 sheet TE. Plenty strong, even when approaching Slow Rat speeds with a runaway OS 25SF. If everything fits well and your glue joints are solid it shouldn't be a problem.

I am building one now. the big problem I am having is breaking the ribs at the trailing edge, I will probably put some triangles of balsa on one or both sides of the ribs tying into the TE to keep them from breaking all the time. I have not put the vertical shear webbing in yet, I think that will make the LE adequately strong as long as I resist the urge to put a killer motor on the model.

I have built both versions of the RSM Ringmaster wing. The new Ringmaster Lite wing is much better and much stronger. It is also lighter and easier to build. Just toss the parts up in the air above the building table and by the time they float down they are properly joined. All you have to do is tack it all together with some thin CA. Everything fits right and tight. The ribs are already laser cut for the A-Just-O-Jig.

Louis,

"Just toss the parts up in the air above the building table and by the time they float down they are properly joined."

Is that like the "big bang" theory? I'd like to know how I can apply that technique to building my next stunter!

One of our club members was flying an RSM Ringmaster Lite yesterday, and what ever you have to do to finish the plane will be well worth the effort. He was flying both the Old Time and Modern patterns with no problem at all. I may even have Eric make one up for me.

Dear Sean,
This type of construction is foriegn to you because of the way you were raised. It's not your fault.

Large logs and "inexpensive" balsa hewn into aerodynamic shapes aren't always the way to go.

Listen to Uncle Chris when he says to be patient and use a deft touch when aligning and gluing such small dimensions as 1/16th Contest Grade balsa together. This kind of construction, although new to you, is perfectly safe.

Chris...

P.S. Isn't Uncle Mikey's Ringmaster beautiful? Yours can be to if you do not afix any vinyl stickers the size of the wing onto the model that say US Army. Remember the lesson of the "AeroShell Magnum". Just pick an atractive scheme from someone else's model, and STEAL IT!
Uncle Mikey's looks very nice to me, son.
