Fouga Magister build thread

Inspired by Finland's former jet trainer, I decided to try building one out of foam.
Haven't gotten far with the build yet, but more is to come soon

Beautiful plane.
It looks like you've decided on a very small scale. That plane will be quite challenging to fly at that scale (maybe you intend to use computerized stabilization like SAFE?).
Doing that plane at a minimum of 1.5 meter span will make it a lot more pleasant to fly.

I like youR aspirations and look forward to your first flights.

I have always admired the Fouga Cyclone as well.

I built and flew the early Ziroli version back in 1969 as my 1st RC 3 channel model.
It was flying higher than the returning mornings' sortie of F105's
as they peeled of from echelon approach for a landing.
I was a bit nervous that some officer/Pilot would be coming to the model shop to
dress me down but it never happened.

It would be quite challenging to install two EDFs on that small size plane.
You could use two small propellers to fake it...
Or make it a pusher.

Why do you believe that it will be hard to fly? I would like to make a bigger one for sure, but bigger plane=bigger budget. This plane is only my 2nd scratch build one so I want to learn by making smaller planes at first

My plans are that I will install just one edf inside it. I believe it should be just fine

It's all about combination of wing loading, Reynolds number and aspect ratio. You've got a fairly high aspect ratio and low Reynolds number (and probably somewhat high wing loading for that scale). Not great for ease of handling. Small scale does not tolerate high wing loading well. Scaling up allows for tolerating higher wing loading much better. And typically (for our foam models), scaling up results in lower wing loading as well, improving things even further. High AR means high stall speed if at very low Re#. Again, scaling up greatly improves that.
That plane at 30" span will behave very differently than that plane at 60" span.

Anyway, I and others discuss the effects of scale to death in other posts, so a search will yield further details.

Will you be installing the EDF in the middle of the fuselage or on its side?
What size EDF?

It will come in the middle and I'm thinking of 50mm unit. The plane is 75cm long

Today I made the intakes. I was trying to make wings too, but my hotwire cutters power supply went dark, so I need to find replacement for it now

Where would the inlet and exhaust of the EDF be?
