Fouga Magister

[Railrunner130]

I am looking to do some repaints of the Restauravia Fouga CM170 Magister and the CM175 Zephyr. I've scoured the internet looking for photos of US-registered Fougas. I have a few pics of my own, but I'm looking for more detail than I'm seeing. Mainly, I'm looking for a left and right profile or something close to that and details of emblems/artwork. If you have some, or know someone that does, please respond or drop me an e-mail. I'd be very happy to even find someone that owns a Fouga that can take some detailed photos for me.

Thanks!!

I have access to a Fouga here in the US, but it's a Swiss-built example and doesn't have much for artwork. Let me know what you need though if I can be of use and I'll get it next time I'm at the airport.

Hello,

I know Sean Kneppers has access to one at the Aviadrome in Holland; he sent me some nice detailed snaps of one last year when I was planning to some repaints. I think his user name is skneppers on here, but Sean, if you're reading this, perhaps you can help out?

this is slightly off topic. but when I got the magister I noticed that it was hard to keep the engines from overspeeding when you were trying to climb or cruise at the speeds you were supposed too (250 knt IAS,or m.45) even when barely climbing. I also noticed at a decent cruse alt (around flight level 25), the engines would exceed there rated rpm of 21500 even at less then 75% power. I did some research on the engine and I think this was because the inlet size is too big in the config file. (1.29 square ft.)

from looking up the certification of the engines, the Marbore IV has a nozzle size of 67.2 in^2. since this is a turbo jet engine, I figured the inlet can't be much bigger then the exaust. (and if you look at photos of the bare engine, both, the inlet and the exaust have cones that restict them. reducing the area)

I reduced the size of the inlet to .75 square feet. now I can get much closer to the perfomace indicated at climb and cruse RPM (18,500)

I am thinking that what the author thought the inlet area on the engine, was actually the INTAKE area on the plane itself. :think:

just thought this would be of intrest to others flying this great model.

I have been enjoying my self flying it.

If you like, I can measure the inlet to get general dimensions when I'm there too and give you an accurate inlet size. The inlet is bigger than the exhaust, but not by much.

thanks for the help. I dowloaded the faa certification document for both the II and the IV (E-302) but it just gives the nozzle area for both engines, not the inlet area.
also it is a single shaft engine. I think the flight model assumes a twin shaft engine so I am not sure how well FS can actually simulate this engine. not to mention the fact that FS assumes a turbofan. and this is a turbo Jet. what gave me the best idea of the size what this pictiure I found on line for the II

as you can see there is a cone that really reduces the effective area of the inlet.

this is the sight I got the picture from

Actually, FS wants the area of the intake, not the inlet face of the engine in that section. It does some funky calculations to figure out how much air can then get to the engine.

As for a single-shaft engine, it works well enough as long as you set the bypass ratio correctly.

That would be great!!
