Miles M5 Sparrowhawk

[Robert McKellar]

So here's my take on the Miles M5 built from Walt Mooney's plan OZ1193.

 I printed the plan at 1/20 scale which gives a span of 16.8". I drew my own wing and Htail plans to build over as the drawing was a little wonky and not quite symetrical.

 I raised the wing in the fuselage a little bit to better match photos which show the fuselage protrudes below the wing. The fin shape was tweaked again, to better match photos.

 The tail features a built up airfoil cross section and I used scale rib spacing on all flying surfaces. The wing uses the Dave Reese style construction with 1/20 square ribs. The upper ribs were laminated from two layers of 1/20 x 1/40 balsa.

And here's some shots of the wing construction.

 This model will have seperate control surfaces mainly because I like the scale look. The spar joiner is 1/64 ply.

Nice work.

Very nice work. 
Take it you've found a fairly easy way to reduce image file sizes.

A very nice and light construction!

[Robert McKellar]

Thanks for the kind remarks!

 Here's the model all framed up and at this point it weighed 8.8g

That is lovely!

What he ^ said!
Sounds very light for the size.

 For covering I use Asuka tissue with nitrate dope and sanding sealer over the bare balsa sections. Just needs a windscreen, paint and I'll be building a section of a dummy cylinder to fit in the nose. It will need some nose weight so might as well be scale detail!

 The weight after covering is 12.33g which I'm very pleased with.

Cheers!

Very impressive work and interesting structure topped off with a neat covering effort.

Good luck with it.

 Thanks! I'll be one nervous chap on flight day!

Beautiful model of a beautiful airplane.

Some people are more patient than I am.

It looks as if you've used a flat bottomed wing section. Correct?

 Yes, I did use a flat bottom airfoil.

 They perform better than conventional airfoils at low Reynolds numbers and it makes building a lot easier.
