Looks like you are using the Behotec Air up/Air down/brake valve.
Since you are using air up spring down retracts, you can use the Behotec valve to also close the doors and save on using a 2nd servo, 2nd channel and an extra valve

mberme

It is true.
But, the real plane closes the doors on gear donw.
A caprice for my ...

Hello Guys, any new updates on this great project? I am very keen on buying a mirage for my Wren44Gold but would love to know more about the flying characteristics (turbine or EDF). cheers Andre

Mirage 2000 EDF as reported by Markus on RCGroups:
Quote:

First of all the mirage is absolutely easy to fly - don't worry.

I have following throws:
Elevator Input: +/- 16mm, expo 35%
Aileron Input: +/- 6mm, expo 50%
CG: 305mm from Intake

Take-off (bungee): The mirage goes straight along the bungee without any tendency to break off.

Steep turns: She has the tendency to "fall" into the turn

Slow Flight: You can control the mirage up to an AOA (Angle of Attack) of 20°. I flew 2 times a circuit with an AOA of about 15° due power loss with contracted ducting (already mentioned before). Be aware of the possible speed loss with high AOA and turns, increase power always for turns with high AOA!

During stall she goes down fast but maintaining wings level and no tendency to flip over. Be aware you need a lot of height to recover as you have first brought down the nose to reduce the AOA and regaining speed.

Landing: You need a long way to reduce the speed. On final as long as you can not clearly see an AOA of at least 5° you are too fast for landing (see pic below). Maintain a constant AOA and you bring her in without any problems. In case of a go-around just maintain the AOA and bring up the power, she will climb herself as soon you gaining on speed. Do not rotate before having sufficient speed.

Stay in the vicinity: The biggest problem is to see the mirage far away - stay close on your first flights!

So I hope this helps for your maiden....

thats great info mate. Thanks a lot. I am actually still thinking to get one (after i finish my Vampire). I have a Wren 44 and will perhaps build a turbine version. will post if i pull the old trigger.
Cheers

No time to Mirage, Carnaval

great update here mate. May I ask what the pipe cost from Wren? I assume this plane must go BALLISTIC with the 44, any idea when you plan to maiden? Have you calculated the all up weight including (I assume) one litre of chero? if it is comparable to a 10S set up then i may be mega tempted to run and order one. I am only a little bit worried about the wing loading.

mberme

The tailpipe cost is 35 GB puonds.
But, Wren sent me the MW54 size.
I have an air leak, am thinking about knowing where it is. But I do not reach it with my hands.
I hope that the weight does not overcome nine pounds

monza

Airleaks are a pain. Are you using air up/spring down retracts?

I suggest you put a little piece of sponge on a stick, soak in soap solution and see if you can find the air leak by applying soap on all connections. the one that leaks should crate some bubbles.

The 54 tail pipes are significantly lager than the 44's but since you have so much power compared to a EDF i think you should be fine there.

A weight below 9 pounds sounds great yet I have just build a vampire (EDF) from the same manufacturer and I am clocking 2.9 KG (almost 6 pounds). The wren 44 is around 200 grams heavier than a midi fan. Keep us posted. Really looking forward to hear a report about your maiden flight.

Hi Mberme

Any update on this project? i would be very keen to get a kit but would love to have a flying report given the HUGE power supplied by a wren 44 (around a 120mm fan punch on 10S).

Any more pictures?

Cheers
Andre

Manuel, What happened? Did it fly? Crash? Anything? It would be beneficial to others like myself who might be interested in doing that same model!!

Thanks

Hello
The Mirage flies very well.
The first flight was delayed by the fault of the main wheels.
The wheels made by Airpower solved the problems.
The plane only needed a point of trim in ailerons, his flight was very easy to control.
The problem was the color of the plane. The zone of landing was covered by a very dark clouds, the Mirage was very difficult to see.
After several attempts of landing, I came to land with a very low speed and the plane stall. Clean stall.

El Mirage vuela muy bien.
El primer vuelo se retrasó por culpa de las ruedas del tren principal.
Las ruedas fabricadas por Airpower resolvieron los problemas.
El avión solo necesitó un punto de trim en alerones, su vuelo era muy fácil de controlar.
El problema fue el color del avión. La zona de aterrizaje estaba cubierta por unas nubes muy obscuras, el Mirage era muy difÃ*cil de ver.
Después de varios intentos de aterrizaje, llegué con una velocidad muy baja y el avión entro en pérdida.

I'm not sure what you mean by clean stall? Does that mean that it stalled and crashed? Is that 7.9LBs? Man that looks awsome! Were you able to get video?

mberme

It is true.
Stall is not the correct word, The low speed did that the descend rate was very hight.
A better vision of the plane had allowed me to correct the bad approximation.
When I fly the Plane was alone, Only wanted to verify that the fixation of the wheels was nice.
Finally I decided to put it in flight, but the conditions of visibility were not good.
The damage in the plane are repairable, but two new projects do not allow me to repair it for the present time.
I recommend the Mirage, want to finish the other planes to begin with his repair.

Es cierto.
Perdida no es la palabra correcta,
La falta de velocidad hizo que la velocidad de descenso fuese muy grande.
Una mejor visión del avión me hubiese permitido corregir la mala aproximación.
Cuando volé el Avión estaba solo, querÃ*a comprobar que la fijación de las ruedas estaba bien.
Finalmente decidÃ* ponerlo en vuelo, pero las condiciones de visibilidad no eran buenas.
Los daños en el avión son reparables, pero dos proyectos nuevos no me permiten por el momento repararlo.
Recomiendo el Mirage, estoy deseando terminar los otros aviones para comenzar con su reparación.

I currently have this model on my building board. I was thinking about cutting out flaps from the one piece elevons surface in order to slow the model down when landing. What do you think? Is it worth the effort? What's the landing speed like? Does it need flaps? What Airpower wheels did you use for the twin nosewheel arrangement? Thanks.

Tengo este modelo en mi mesa de trabajo. Pensaba cortar flaps de las superficies de profundidad/alerones con el proposito de que la aproximacion al aterrizaje fuese mas lenta. Que piensas? Valdra la pena? Como aterriza el Mirage? Necesita flaps? Que llantas ruedas de Airpower utilizastes para el tren delantero? Gracias.

mberme

I think that the planes of this type (Delta wings) do not use flaps, only speed brakes.
In the nosewheel assembly use Sullivan Skylite 1.75 wheel, They are narrower that I found.

Pienso que los aviones de este tipo (Ala delta) no utilizan flaps, solamente Aerofrenos.
En el tren delantero utilice ruedas Sullivan Skylite 1.75, son las más estrechas que encontré.

Hello, I am a new in this forum and saw the issue, I would like to ask . I intend to acquire the Mirage from "jetarrows" in EDF version, and I am thinking about what equipment (Elevon servo) will be need put in Jet. The manufacturer says in the manual to the wings used the "Futaba S-3150 Digital servo" (seems a bit obsolete).I thought as an alternative to used eg "Hyperion Atlas DS095 - FMD digital wing" or "Hitec HS-5125MG Digital Wing" and similar. Because you have practical experience with this Jet, what is your opinion for it, what servo (torque) you recomended to use for thi Jet ?. thanks Sampson

mberme

Hello
The box of the servo is made for the S3150. To place another servo is very difficult. I had the same problem.
THE servo S3150 is a very good servo, I fly my plane without any problem with the servo.

Saludos
Manuel

samsone

Hello Manuel, Thanks for your response, I do not know if you mind your the Servo frames ( http://www.icare-rc.com/servoframes.htm # Wing_removal_tool.) which I believe, solve the installation problem somewhat different types servo in the wing. All my concern is that retract Digital DSR2-46T system (http://www.hobbycity.com/hobbycity/s...dProduct=10387) that I have already ordered, works certainly reliable only from 6V and more. Necessarily there I will put UBEC (6V/5A), practically I do not know if this will be marginal voltage for S3150, which I see as obsolete type servo and little expensive. Seem to me a bit exaggerated the 4.5kg torgue servo for this plane,what your opinion? sincerely Sampson .

Hi!
Do you remember what the weight of your Mirage was?
Still flying?
Have a HT Mirage without propulsion system, trying to figure out what I should go for. Lambert T-25, Jetcat P-20SE or Wren 44

Hello
The plane was weighing 3950 grams.
Transform the plane into electrical propulsion, but a breakdown of the motot in flight I end for destroying the plane.
