Default FeiBao Mirage 2000 Build

Although not a very popular model,for the life of me I cannot understand why, I thought I would post some build photo's and enter some more information regarding this kit as the currently available information for this Jet is very limited.

FeiBao Mirage 2000

Length:96 3/4"(2460mm)
Wingspan:64 1/4(1635mm)
Power:27 to 36lbs (120 - 160 size Turbines)
Radio:Minimum 7 servos (unless using combination gear valve)
Weight 28lbs. (Dont ask me how the model in the instructions came to this weight, mine is 36lbs even)

Jetcat P160SE
Elevon 4 x HS7955TG
Rudder HS6965MG
Rx 2 x Futaba R6014HS & 2 x Orbit Powerjacks
2 x a123 2600mAh
42% 50A Battery share
Airpower EV-5U
CofG 420mm (No extra ballast required)


Building this jet has renewed my faith in FeiBao, of all the 9 Chinese jet kits i have built over the past 12 months, this one has been pretty good. The glasswork or perhaps I should say "carbon work" as there is a bucket load of carbon fibre wherever you look, any way the glasswork is perfect.
The biggest letdown on most kits is the retract mounts, most require further strengthening or even a total refit. This Feibao Mirage, the mounts are simply awsome, 6mm 8 layer ply capped with 2mm fibreglass sheet. The surrounding support and ribs are also of similar quality ply all nestled between carbon fibre reinforced wing skins.

Structurally the glue and materials used throughout the manufacture are all you could ever want, the manufacture tecnique is also of very high standard although a weakness in mathematics was revealed against whoever designed the main gear door goemetry, it was just wrong, even 180psi would not close the doors fully. No real problem, a couple of minutes to rip out the supplied setup and start afresh. 3/8 Robart rams fitted in place in better locations to give the required moment and action, now see's the doors close with authority at 60psi.
The only other structural mod i chose to implement was to install 2 servos per wing and split the flight controls. For one, the full size is split and secondly, perhaps more importantly on this model the control surfaces are huge and the fear of fitting a single 25kg servo per wing panel just made me cringe at the workload the servo would be subject too. So 2 x 25kg HS7955TG servos were fitted per panel. There is no option for this on the standard kit but with a little planning and a few hours see's the new servos fitted in plenty of room and in a good mechanical location.

The standard kit is furnished with your regular Chinese bag of hardware, you can use it and would sufice, but it does not do too much for the bling factor and as this jet was being built for myself, (No I dont skimp on customers jets, but rather let them decide on what hardware to use), so why not treat it to some better equipment. Aluminium servo arms, Aluminium ball ends where fitted to 3mm Steel/Carbon pushrods.
Also supplied is fibreglass cockpit tubs for those wishing to build there own detail, but for me, I chose to purchase FeiBao's cockpit assembly, and although i was fearing its arrival i was really surprized at what showed up 4 days after placing the order. A perfectly constructed and perfectly detailed scale cockpit that is very robust and nothing like the rubbish you pay $400+ dollars for from other Chinese manufacturers. It even fit perfectly from box to airframe. I did choose to make the cockpit and canopy a one piece affair simply as a personal preference.

So that should be enough for now, I will add more in no particular order when time available. Also photos are of no particular order.

More, The first photo shows the new main gear ram set-up. The last photo is of the original main gear door ram assembly and geometry. BVM aluminium hinges arrived today to replace the standard nylon hinges.

I seem to recall that the author of a report in RC Jet Ingternational lost his due to failure of the hinges. You may want to take a look at that.

I also read the same but then continued reading and the guy that received the leftover wing stripped it down and did further testing on the hinge points with good results. I did look into this with mine and am more than happy with them. This was the main reason for fitting 2 x servos per wing. It is just such a huge control surface that if allowed to flutter you would not blame the hinges for letting go.

That was me...I had keith's scrap wing and had a good look at it...if you want any more detail, go here...

http://jmajets.co.uk/board/viewtopic...=1077&start=15

...and look at page 2 post #7.

There were loads of pictures that were 'lost' when the site software was updated and I lost the will to live at the thought of posting them all again. I have them if you want me to post here for info...let me know.

Thanks for starting this thread. I have been looking at this plane for a while. My main concern is how well made the landing gear is as this was a concern of a fellow pilot who had some experience with one.

Hi Philjac94

Thank you for doing this post, the Mirage will defiantly be my future project.
I have one "problem" with it. I love the single seat Mirage 2000 and not much the double seats,
I have a " big problem"!!!
So, keep the posts and the pictures coming.

Thank you
Best regards
Avi

The landing gear is ok, the brakes however are a problem. The machine tolerances are way too tight for aluminium, you can overcome this by machining the end face of the brake (if you have a lathe) or by fitting a copper washer (glow plug washer) between the brake hub and the wheel, otherwise the wheel will gaul against the brake end face, and lock your wheel solid. Also with your drum sander in a dremel, grind down the Brake pad O ring so that the wheel spins nice and free.

I too prefer the single seat variant, but unfortunately FeiBao dont make this an option. Aviation Design has the single version but given the amount of work required to complete the AD kit, i felt happy to go with the FeiBao.
This jet has taken 2-3 weeks to build from kit to flight ready. I think if it were AD after 2-3 weeks i would still be looking at the box puting off the build till tomorro.

Hi i am the guy who lost a model because of flutter,you have done the right thing in fitting two servos will be ok with that mod,the brakes are a problem,i took out one O ring completely and sealed the air hole with epoxy,with one O ring they work nice with two they lock up and take out the brake nipple!!I found the retracks a problem in that they would not go away,i fitted 4mm tube and used two air valves which cured the problem apart from that it fly,s great regards Keith

Sorry you lost your Mirage.
My brakes work well now with my mods done. Not to sure how the retracts will like the air loads but functions well on the test stand, like all retracts I know, they are a work of art on the stand but a piece of [email protected] in the air. I have set my door up delay to around 8 sec to hopefully allow enough time to get them away.
What did you do with the air brakes on your model?? I have mine activated with the wheel brakes so they deploy with braking. The closing side of the ram is connected to the gear up line so gear up, dive brakes closed. On the ground after braking they can remain hanging until gear retracted.

Megafly, Not sure if I can do a build thread, I work for a major defense aerospace company. So my time is limited posting pictures and answering questions in a timely manner, but will consider it .. could be fun. I will be attending Jets of the South 2017 tent #1, if you can make it .. come over and say hello. I'll have my Skymaster Dragon sport jet. Hope to see you.

Peter love is the gentleman who wrote current build manual for Fei Bao Mirage 2000. Recommended using Futaba BLS152.. 31kg 1093.4 oz in .. servo for each Elevon. JR DS 8711 is 400 oz in @ 11.6 kg at 6 volts. I feel that servo can handle the work load and save all addition work, what do you gentleman think ? ... I agree it would have be nice when Fei Bao redesign the kit with LE Slats that dual ailerons per wing would of enhance scale appearance IMHO.
