Scratch built depron micro Macchi 72 Schneider racer


This will be a semi-scale Macchi 72 Schneider Cup racer scratch built from depron and E-Flite micro floats, and the guts from an E-Flite micro Beast biplane.

I have no plans and will be basing the model on photos and what seems right at this size.

I'll be using my own personal judgement and experience to decide on a good balance of size, wingspan and wing-loading for what I hope will be the best compromise for a good flyer.

The photo shows the main components that will magically transform into a new model.

Wing and fuselage sides are 1/8" foam, tail is 1/16", all with 'grain' lengthwise.

Wingspan is 18". Projected (hoped for) weight without floats is 2 ounces.

Wing sanded to undercambered airfoil, ailerons cut, basic fuselage construction started, motor mount fashioned, and floats assembled.

About 3+ hours for this little bit behind the cockpit.

Still a bit of sanding needed.

More progress: fuselage top and pilot opening, cowl and spinner.

More sanding is needed but basic construction is done and it now looks like a Macchi 72.

Steady progress, a tiny bit by tiny bit.

Windshield frame cut and glued in; made a slightly larger than scale scale fin and rudder; receiver in place; tail linkages prepared.

About 2 hours work.

I have been posting these on our club's website, and thought I'd share here.

I'll post more as I progress.

Very cool Micheal! Should we start thinking of reviving the Schneider cup racing in Kingston in micro form?

Hi Martin

Can you put up a small temporary pond at the field?

We're seriously considering a Schneider Cup type event here in Toronto.

The event would probably be closer in style to our "Warbirds" or "Jets" events, where each of simply take a turn to fly and talk about our models as related to the event.

It was Robert who egged me on to do this, and he is considering making one from a GWS Formosa kit.

We'll keep you updated, and feel free to follow the discussion on our club's website. Robert is to start a new thread on the subject soon.

Looking good. Hope the avionics live up to the 'racer' aspect
One question though; that elevator joiner looks oddly located.. is it ?
