Telemaster Senior laser wing construction

Hi folks

A friend and I have to rebuild a wing for his Telemaster Senior and I
was just wondering if anyone had built a Telemaster Senior wing (or
similar) using the 'Laser Method' where the wing ribs are cut from blue
foam. I have have built conventional ribbed wings and veneered foam
wings but not this hybrid method and I was thinking this would be a
chance to try it.

Any opinions on the suitability of this large wing etc would be appreciated.

Billy.

I guess not.

I've never heard of this method. Can you give me a quick rundown on it or a
link to more info? Sorry I can't help.

Thanks,

Well as, I remember it (bare with me here as it has been awhile since I
read about in a book by a guy called David Thomas I think - 'Radio
Control Foam Modelling') you don't work over the plan but directly on
the building board where you mark out the rib positions directly on the
board and the cut nice true and square rectangular slices of blue foam
with a hot wire at differing thicknesses depending on how far along the
wing the rib is placed (Something like 1/2" at the root at about 1/4" at
the tip). Tack glue the rectangular slices on the building board in the
wing rib positions. Next use your two piece wing profile templates as
you would to hot wire the top curving cut so all the glued ribbed are
cut at the same time. You have a row of ribs with the top wing curve
cut. Then use templates to cut the spar slots on the same way. Glue in
the spars and add the LE and rib capping so you have a have finished
wing (top half). When done place the templets for the bottom half of
the wing in place and hot wire the bottom profile of the wing and turn
over and do the same for the under side spars capping etc. as you did
for the top.

This is how I remember it but just broadly and I have forgotten the
finer points. But the bonus was meant to be that it guaranteed a
straight, warp free wing that was quicker to build than balsa, was the
same as or lighter than balsa and stronger than balsa. It was meant to
have been a method developed in the US for wings on models doing
Aresti(?) style aerobatics (What ever they are!!). I am currently
tracking down the book I mentioned above. But I was just wondering if
the Telemaster Senior wing would be a good candidate for this method as
I just want to give it a try really and to guarantee true, square wings
is a bonus.

Cheers,
Billy.

I have managed to find a copy of the the offending book. Would you
believe it, it was in the local library!!

If anyone is interested I have made up a pdf file from scans of the
relevant chapter (so I had something when I take the book back).

Having read the book Phill, I think what you said is right - should
work. The guy in the book mentions building 80" wings no problem and
the Telemaster wing is only about 5" a half bigger. Think I'll give it
a go.

If the file is small enough to email, please zap me one.

Two flavors Phil. 2.1Mb and 1.3Mb can make you a smaller one if you
want? What flavor do you want

I just finished CAD work on the senior telemaster wing. I preserved the exact airfoil section while lightening a bit and adding pass though for electrical conduit (soda straw). This is a nice way to route wires for servos and lights etc in the wings.

I'm also adding a strip of carbon fiber to the top and bottom spar. All and all, the updated wing will be lighter, stronger and a snap to build. Everything is interlocking so the wing will practically fall together.

Here's a couple of photos for you. The other part is the motor mount for the brushless motors. 1/4 by 1/4 will make up the framing for the nacelles. (I'm going to make mine a twin with two large Jeti brushless motors.

I have just finished completion of a laser cutting machine so if any of you are interested in a set of ribs let me know.

Best, Lawrence

whoops, forgot photo. Here are the motor mounts
