Mikey, Here is a CG trick I use that gets me in the sweet spot every time. You can share/use this method too if you like. Measure the wing width at the fuselage, divide by 24, multiply by 7 (7/24), and the product is how far back to make a tic mark on the wing. Do the same at the wing tip. Draw a straight line between the marks. Where crosses the fuselage center is the CG. A bit forward for fast & stable, back for aerobatics. I'm doing a build video showing this. Happy Flying!
Yes! It should work great! Measure the diameter of the blades, in this case 40mm, calculate the area (pi x r^2), then do the same for the nose cone or the motor (which ever is wider). Subtract the nose cone/motor area from the blades area. Divide by pi, get the square root, and multiply by 2. This is the diameter the cone should be for max efficiency. Happy flying!
Hey rustyr.... I built mikeys f117 and it flew great. Loads of power..... Until I trashed it anyway! ;-) my point being, if I can build one, anyone can. Mikeys planes are excellent, he makes it so even a first time builder like me can do it, just take your time and enjoy it. It's very satisfying building your own and watching it fly. A lot lot cheaper than buying factory built plane and you will learn a lot as well. Need more depron to make my f117 mark 2 . Hopefully I won't destroy this one!
@MikeysRC I used a 20amp ESC, the motor I took off from the hobby-king's Floater Jet (2100Kv Out-runner), 2S 1300 Lipo. I never weighed the thing. But it was very small like yours, It had a total wingspan of 18 inches and wingtip trim of 2 inches, had a length of ~14 inches. No airfoil just angled edge like yours. Lots of fun very fast too. it would climb vertical too. I crashed it and is pending a rebuild, so i don't have a video.
@9TailedTechFox On deltas it seems to be about 1/3 of the way back from the tip of the delta as a good starting point for trying to balance it. BUT.....I use the glide test method for determining the CG before flight.
@lewandlo Actually the cool thing about the foam I use is that there is no need to soak the paper in water. It's simple to peel it off...just grab a corner and pull. The glue has just the right amount of strength to keep the paper on when you wan ti and still have the ability to come off with out having to soak.
nice one Will. I have been recently getting more and more into micro flyers. just waiting for my 460 mAh 3s rhino pack to arrive so i can get started with my next project. i don't like the paper on my planes either and have started using Styrofoam plates for the low stress areas to keep the weight down. really like the curved intakes, it's similar to what i'm building right now.
@808FlyBy Yes all true. Open cockpit was to make it really easy to get the battery in and out to find CG. Once found a cover would be easy to instat. The reason the plane is this size is because it was designed around the power system and the max thrust it produced. So I had to keep it as small and light as possible.
Hey, I've played with these sorts of models for a bit. Try a shift of CG fwd by about 2mm give or take as well as perhaps a horizontal small streamlined vector plane in the tail pipe to direct the thrust very slightly downwards as it looks like the thrust is not pushing the model directly forward. I think this could make it perform a whole lot better. Anyway - Love the vids!!!! Cheers!
@MrNerfmod 2 cell was that that EDF was rated for. It's really more about what the KV of a motor is. A higher KV motor will spin just as fast with a 2 cell as a lower KV motor withe a 3 cell.
Replace the ducted fan with a pusher propeller and it will have heck a lot more power, flight duration and will be quieter. I had build a series of these mirage jets testing the best configuration.. After tying the original 30 degree wing sweep on the plane, I unswept it to 35 degree for far better performance.
Hey great little flier ..... Are there plans to download in the near future? Oh I have been waiting for you to put the FPV plans out too.Are they coming out soon? . I really want to say thanks for all the hard work for you put out for all the planes you create. Very fun projects.
@BigCatLenny THe airframe is made out of one sheet of $1 foam board. Cheapest transmitter / receiver you can get is about $45. The rest of the electronics cost about $50.
@MikeysRC Would you mind trying to make an exhaust cone? Make it shrink down to about 60 to 70 percent of that current exhaust outlet size. Make it out of construction paper and either tape or glue it on.
@wildhover Cool. I removed the paper to curve the foam. Though the paper HAS to be on both sides of the wings to keep it stuff. If I removed the paper the wings would have been like floppy pancakes or....depron. =)
You mentioned you were peeling paper off the foam. Here is a quick and oh so easy way to never peel again. Depending on how many sheets you want to get the paper off .You want to submerge the foam board completely under the hot water. . I used a couple of ice cream containers full of water to hold it down before I put the hot water in. Bring the hot water level up and let it sit in for as long as you want . You will see the paper just bubble off the foam. No more peeling heheh. good luck eh?
@LTF85199 I thought an EDF would be a fun challenge. Yeah I'm sure it would fly real well with a pusher prop. Can you post up some specs on a motor and prop combo that would work well on a plane that weights 160 grams AUW?
it looks like its not getting any lift at all. Normally the ducted fan would be powerful enough to just push the jet through the air but this one is not. perhaps a small airfoil would help it gain some altitude?
@VINCENT1975100 I agree. Tail heavy for sure. You could really tell on the turns. It was plowing air the whole time. Cool little build. I also recommend removing all paper off the foam board. See my videos for a simple method.
Love your work, but when talking about lipo's Since when does more capacity mean higher discharge? Doesn't it just increase run time? C rating is the output, for eg I have a 4000 mah 90c which is way more power then my 6500 mah 60c. I'm always hearing people say this but I think they are still thinking of the old days before lipo.
im not a big edf nut. but i know a bit bout electronic s my question is can this motor handle a 3 cell? it will probibly draw alot of amps and you would have to up the speed control. but if it spins faster it should move more air causing more thrust. im guessing a ballpark of 200grams. get a low compasity 3s25c lipo bout 500-1000mah. it should take a longer flight and push the little thing round like a jet. and same motor can be backed off on the throttle better to fly just my 2 bits
@m18xray In this vid a try a couple different lipos. But I recommend a 1000mAh 25C 2 cell for this set up. Click on the link under the video to the gens ace battery I recommend.
you could make it yourself a lot easier for a first time mini by making a wing/disc type of plane it would be awesome if u could give that a shot I would love to see that type of mini plane with 1 of ur designs
i like inducted fans because when inside a plane body in most minor to sometimes even severe crashes not being an open prop but i have no idea where to get one and also have you ever considered making a bomb dropping rc aircraft
Hi there, i am new to Rc planes and i am interested to know how much thrust can a dual 50 mm edf produce? Can it power a 700g - 800g scratch build plane?
reading the posts ... cant see anywhere about the open cockpit. wouldnt this cause drag? also .. slightly bigger = more lift .. bigger lipo = more power. 1ins all round would make a HUGE difference. flew nice.
Ibuild a little space shuttle also with elevon-mixing about 100g flies reelly good. May i laod a video up soon hope for good weather so far so please Watch it
@MikeSVOR My bad, I meant to imply that the way it was orignally buily with a taper. So what you see in the video is the plane with the tapered exhaust. Honestly what the plane needs is a slightly larger capacity battery than what I was using in the video. The plane was not meant to be fast. Just a small park flyer with an EDF. It flew fine but the battery was just too small to keep up the voltage under the load for very long.
Well the output of a battery is the C rating times the amps per hour. He said both batteries were 20c, so the 800 mah one had an output of 16 amps (8x 20) while the 900 mah battery had an output of 18 amps (9x20)
@MikeysRC Sorry dude I meant the plans for the latest fpv slow flyer . The plane with the huge wings that flies as fast as walking. You were working on the final touches. Oh yes the plane you flew under the bridge. Thanks for the response.
Perhaps it needs a higher capacity battery but I think that is crying out for a 3 cell battery; the higher voltage will give it more thrust and I believe that this AEO EDF will run on a 3 cell.
@Tsavah Yeah I have not yet gotten this jet to preform like I want it too so no plans yet. Yes canards coud be put on but then it wouldn't be a Mirage 2000 it would be a Eurofighter =).
@MikeysRC but maybe wen you should have time can you make a smaller sport trainer or somthing easy to make then I should be able to transform one of my erc micro p-51 mustang to it
@pistolpetepeterson The specs for the motor do not list a 3 cell. So I'm pretty sure it would fry the motor. But yes....before the motor was cooked it would fly faster =).
where are the plans for this one? i dont see them on the website, have a plan to remove all the electronics from my alpha jet and have a slightly larger version of the mirage
@nsoxike The times it flew high-alpha in all but one clip where I did experiment with the battery farther back...were because I was intentionally flying it like that. If you could see the amount of up elevator I was giving on the controls it would become apparent that it's not tail heavy.
Yeah I still check out my comments. Yes large EDF's are much easier. But there are several examples of fast micro EDF's. If I spent more moola on my power set up I could get this plane to fly better. I didn't chuck it yet so someday I might try a better micro power system.

Thanks for all you do for us mikey! Not many people out there that would design from the ground up and then give us the plans for free.
Yes! It should work great! Measure the diameter of the blades, in this case 40mm, calculate the area (pi x r^2), then do the same for the nose cone or the motor (which ever is wider). Subtract the nose cone/motor area from the blades area. Divide by pi, get the square root, and multiply by 2. This is the diameter the cone should be for max efficiency. Happy flying!

@gt40x4 You either need a seperate "V-tail mixer" or you use a transmitter that has a built in V-tail mixing function.
I Love your planes! We always learn something.
Thank you for sharing.
@9TailedTechFox On deltas it seems to be about 1/3 of the way back from the tip of the delta as a good starting point for trying to balance it. BUT.....I use the glide test method for determining the CG before flight.
Genius. What handling - wow. Kudos ! !

Well you have cracked it with this one ,their will be a lot of downloads for this plane
10/10
Nice, I've never done a scratch build, I'm really thinking about making this one my first.
Really nice plane
I like it. :-)
Thanks for adding so much info.
Great job
Greetings from Belgium

nice one Will. I have been recently getting more and more into micro flyers. just waiting for my 460 mAh 3s rhino pack to arrive so i can get started with my next project. i don't like the paper on my planes either and have started using Styrofoam plates for the low stress areas to keep the weight down. really like the curved intakes, it's similar to what i'm building right now.
We have been waiting for a long time.dude I think you should .so we can start the build asap.

@MikeSVOR Yeah I basically did that already. The exit hole for the exhaust air is tapered smaller than the inlet area.
Cool plane. You should try programming your ailerons as flaps to try some high alpha and better landings.
@MrNerfmod 2 cell was that that EDF was rated for. It's really more about what the KV of a motor is. A higher KV motor will spin just as fast with a 2 cell as a lower KV motor withe a 3 cell.
@mmmbcn I used Dollar Tree foam board. It's very easy to remove the paper on both sides. Then it bends very easily.
Yes this is true, just like many of my other plane designs and they fly well.
Replace the ducted fan with a pusher propeller and it will have heck a lot more power, flight duration and will be quieter. I had build a series of these mirage jets testing the best configuration.. After tying the original 30 degree wing sweep on the plane, I unswept it to 35 degree for far better performance.
Sorry man I never made plans for this jet. GLad you had a good experience with the FPV V3 though.
I'm with you Rusty. I'm going to look at a slow plane to start with.
Hey great little flier ..... Are there plans to download in the near future? Oh I have been waiting for you to put the FPV plans out too.Are they coming out soon? . I really want to say thanks for all the hard work for you put out for all the planes you create. Very fun projects.
You should try a small 3s, if your power setup permits it!
Great plane! How you curve the foamboard like that?
I love all your planes
@MikeysRC @ Thank you for quick answer. Cheers from Europe.
Nice. Looks like a lot of fun.
@BigCatLenny THe airframe is made out of one sheet of $1 foam board. Cheapest transmitter / receiver you can get is about $45. The rest of the electronics cost about $50.
Can you make some PDF plans for a F-14 TOMCAT? Love this video!!
Yeah you will LOVE the Pylon. WAY more fun than the Mirage.
thats so cool cant wait to build it
@RCB0B Seemed pretty good out of the box. I didn't try to balance it.
Hi there! Great little plane indeed, I'd like to make one of my own. Are the plans online? Can't find them...
@MikeysRC Would you mind trying to make an exhaust cone? Make it shrink down to about 60 to 70 percent of that current exhaust outlet size. Make it out of construction paper and either tape or glue it on.

hey Mkey try making the end of the nozzle smaller and you might get more thrust
@boomerangfreak What would you prefer Rice Crispies or Captain Crunch?
@HBparkflyers Maybe when I find the right motor battery combo.
@Rcflygarn When it's flying slow then it needs plenty of up elevator. But no it's not pitchy when I have the battery in the right location.
Correct me if I'm wrong but it seemed to be a tad tail heavy. You might use the batteries to push the CG forward.
You should install a second ducted fan behind the other one that spins in the opposite direction to cancel out the torque
do you ever use airfoils in your wings because on this jet it seemed as just a completely flat wing
I love it! Small and good
Another fine job
@mmerry2 I did try that.....for some reason I couldn't figure it out with my DX6i programing. =(
it looks like its not getting any lift at all. Normally the ducted fan would be powerful enough to just push the jet through the air but this one is not. perhaps a small airfoil would help it gain some altitude?
Hi Mikey, There are a lot of smaller EDF's out there. I think I have attached a video of one of mine.
thats nice..i was thinking about gas turbine jet engine but its too expensive good thing you have this video..
@VINCENT1975100 I agree. Tail heavy for sure. You could really tell on the turns. It was plowing air the whole time. Cool little build. I also recommend removing all paper off the foam board. See my videos for a simple method.
@MikeysRC Did it fly any better after that? Got a new vid of it?
Love your work, but when talking about lipo's Since when does more capacity mean higher discharge? Doesn't it just increase run time? C rating is the output, for eg I have a 4000 mah 90c which is way more power then my 6500 mah 60c.

@m18xray Probably after I get the Pylon Racer plans out.
Nice! But where are Plans for it?
Thank You, M.
@vietnamisalv There are no plans yet for this plane. I'm not sure when I'll publish them thanks =)!
@AVAMagneticlev Yeah could be. I was talking more about "commercial / factory made" EDF's and not scratch built stuff.
@m18xray In this vid a try a couple different lipos. But I recommend a 1000mAh 25C 2 cell for this set up. Click on the link under the video to the gens ace battery I recommend.
@TheCheney12 I'm not sure when I'll publish them thanks =)!
@boomerangfreak What materials can you buy?
will are you stil using the dx6i for the mixing ?
Hey Mickey, like your planes.. What wingspan have this one?!
@altops OK YES THANK YOU I DO TRIM MY LEADING AND TRAILING EDGES OFF SO THEY ARE MORE STREAMLINED AND STUFF YAY.
there seems to be a lot of models now that do not use airfoil sections on flying surfaces or rounded edges on tails, intakes and nose cones
When are you going to make a pdf plan?
you could make it yourself a lot easier for a first time mini by making a wing/disc type of plane it would be awesome if u could give that a shot
I would love to see that type of mini plane with 1 of ur designs
i like inducted fans because when inside a plane body in most minor to sometimes even severe crashes not being an open prop but i have no idea where to get one and also have you ever considered making a bomb dropping rc aircraft
damn! when you fly it you make it seem so easy. Cool airplane btw
Hi there, i am new to Rc planes and i am interested to know how much thrust can a dual 50 mm edf produce? Can it power a 700g - 800g scratch build plane?
Maybe a KF airfoil would help?
reading the posts ... cant see anywhere about the open cockpit. wouldnt this cause drag?
also .. slightly bigger = more lift .. bigger lipo = more power. 1ins all round would make a HUGE difference. flew nice.
what kind of foam do you use depron or foam board for your airplanes
Ibuild a little space shuttle also with elevon-mixing about 100g flies reelly good. May i laod a video up soon hope for good weather so far so please Watch it
can she go vertical if you had a 3 cell and possibly a bigger edf?

@MikeysRC I don't know the cuz I live in belguim but it is just that the plans will work perfectly
what did a material you used to construct for a body anyway ??
@Tsavah Yeah I have not yet gotten this jet to preform like I want it too so no plans yet. Yes canards coud be put on but then it wouldn't be a Mirage 2000 it would be a Eurofighter =).
hey how well-balanced was the EDF unit?
Hey do you guys build any Pulse Jet RC Aircraft?
Can I plz trouble you for the wing span, sweep, and cg location?
@MikeysRC but maybe wen you should have time can you make a smaller sport trainer or somthing easy to make then I should be able to transform one of my erc micro p-51 mustang to it
@pistolpetepeterson The specs for the motor do not list a 3 cell. So I'm pretty sure it would fry the motor. But yes....before the motor was cooked it would fly faster =).
it might fly a little better if you make a kf out of some 3mm depron
could you mix the throttle with your elevons to counter torque roll?
Wish I was technically/mechanically minded enough to build one of these!
where are the plans for this one? i dont see them on the website, have a plan to remove all the electronics from my alpha jet and have a slightly larger version of the mirage
can you build on which can fit a camrea and have live footage
can u tell me what are the uses of each electronic part in the describtion ?
@nsoxike The times it flew high-alpha in all but one clip where I did experiment with the battery farther back...were because I was intentionally flying it like that. If you could see the amount of up elevator I was giving on the controls it would become apparent that it's not tail heavy.

I use foamboard and hotglue
