EzFly free plans for great trainer plane


My daughter started to show some interest in flying with me so I decided that sh needed a plane that would not let her fail.

My requirements were:
Durable
Easily fixed
pusher to protect the motor
Darn near fly it self
Cute, she is a girl so it has to be cute.

What I came up with is the easy fly dragon and it flys great. It is rudder, elevator control but I have the ailerons mixed in so she can turn with either stick. With a little up elevator trim and shallow turns you do not even have to hold up elevator. To take off just advance the throttle and it will lift off on its own. It is still fun to fly as it will loop and barrel roll.
Correct CG is between 3.5" and 4" from the leading edge.

While I was drafting it up I went ahead and made a boy version in the form of a WWII bomber. It would be easy to put a couple of military stickers on it after painting grey along with some nose art printed on paper and glued on.
Thanks to Mikebergy for converting it to PDF for me.

The R3 pdf is the latest and includes an extended nose and the motor moved forward to help with the CG.

The plans below are provided for those who want to build their own. No one has permission to produce kits for sale as they are available at www.fancyfoam.com

I put together a video on the installation of landing gear on an EzFly.

Be sure to check out the EzFly Facebook Group.

For those of you that want to learn to fly but are not interested in building a kit, we have the EzFly ARF. It is 99% pre-assembled. All you have to do is glue the wing in place, charge the battery and then go fly.

When I saw the plans, I was stoked! Very cool and well thought out trainer, and NOT ugly. And a good flier to boot!

I saw your plans and downloaded the EzFly's type, and if you look at it for a while ,you could make a profile American WW-2 troop glider or a German gigant glider by altering some of the outline and using paint for effect. What do you think?

I think that you need to take a picture when you are done as it should look real cool. I will be building a regular EzFly "Bomber" before one of the next flyins and then have a drawing for any kids there under 15 as a give away. I will post pictures when I am done. I am thinking of using this for the nose art.

I think this design has a lot going for it . I'm not much into wild and fast models so when anything that comes along for slow and floaty I take notice.

My daughter has been flying hers and enjoys it. She was flying it in the field behind our house and it took quite a beating. Che tore off the front 2" of the nose with 3 hard crashes. A little hot glue and it looks good again.

Where is your CG location at? I could figure it out, but I'm too lazy I'd also like to not have the battery way out in front if it's not necessary...

Not yet. My dad and I are in the planning stages of the build. He is new to RC - I am trying to get him into it as he prepares to retire in a few years, and this is going to be his official first trainer. I built him a BBCub, but ended up flying it more myself before it had an untimely elevator servo linkage failure...(oops! my bad). I will be keeping a log of the build as it goes. I am hoping we will have time to get the parts cut tomorrow. I'll take pictures and post them as we go.

I finally got around to scratching up one of my ideas using the bomber version of the Ezfly. I just traced over a single sheet print out of your plans ,and tweaked it here and there, and with some paint it wouldn't look to bad. A Waco glider would be easier, and they had some with twin engines on .

As far as my dad was able to get yesterday. He won't have a day off again for a few days, so I'll get more progress pics when that happens.

All of the parts fit pretty well on a 24x36 sheet of EPP. We are thinking of extending the rear part of the upper fuselage back to the rudder so it is all one piece, so the build can be assembled in the same manner as most other crutch-type profile planes.

I need to build one of these. My 6 year old daughter says she wants me to build her something easy to fly. I was thinking of a Parkzone BNF small plane but those only fly outside when it's really calm. This looks much better being a pusher. Kinda like that frog plane someone sells online but this one is free! Love the dragon theme, I think she will like that a lot.

We finally had some good weather, so LT maidened the EzFly. First off "the taxi" extremely maneuverable. Second "the launch" took off very easy except I had too much up elev trim, so she brought it back down & I adjusted. Third "the flight" very floaty easy to maneuver with D/R @ 40%. Fourth "the landing" a little bit rough but all came out good with no prop to worry about. This was LT's first flight with RC planes, she thought it was quite easy (I told her it was the plane, that didn,t go over so well). So again thanks for the plans, the plane is everything you said it would be!

My dad got all the foam parts cut yesterday. He is experiencing the learning curve that is cutting foam. hehe. I gave him a few pointers, then he cut, and said my knife was dull. I took the knife from him, made a few nice clean cuts with the same knife... He's learning. My OCD self is having a hard time letting him do all the work.

So I am new to this, which will be apparent by the stupid question I am gonna ask. Is that a "Pusher prop" mounted on there. Where and how do I find the correct style prop?? Stupid questions I know but most props I've looked at do not indicate if they are pushers or not. Maybe a brief explination could help a newbe out. Thanks..

Something like these?

Mayday, you can use a regular prop on these. You just need to make sure that the lettering / numbering faces the front. If you do get a pusher prop, you need to make sure the lettering faces the rear of the plane. I think most of us use a regular prop and put the letters/numbers facing forwards.

Would the plans and build out be basically the same on this plane with 6mm depron instead of the EPP? Any required or suggested changes?

I have not tried it but the build will be about the same. The cut for the wing will need to be 6mm instead of 9mm as well as any tabs or other features that rely on the thickness.

I wasn't able to build my EzFly yesterday as planned, but did get the plans taped together. After work today, I cut them out, made semi-permanent stencils in the hopes that I will use this as an all-around trainer for several people. Then I cut out the parts with my hot wire cutter (it was very fast to cut out that way). I put it together with a combination of Gorilla PU Glue and hot glue. I've got the motor, esc and receiver mounted. I only have the servos left and it is done. I didn't paint it yet, but will do that after the maiden flight. I just wanted to get it done so that I could take it out for the maiden flight.
I thought the build was extremely easy, but I think someone new to building might have some trouble with the plans (not knowing where to cut and where not to. I cut and glued the plane in about an hour. The motor, etc. were robbed from a plane that my youngest son peeled apart a few months ago (when I wasn't around). EPP foam is not kid proof.
I think the plane is basically bullet proof (newby proof?) with the way it is built. It seems stiff enough to fly well, yet flexible enough to bend instead of break. The nose is super strong with three layers of 9mm foam, and the prop is very well protected. The plans were perfect as far as accuracy is concerned. Everything fit exactly where it was supposed to.
Thanks, motorhead, for such a great set of plans! I need to mount the servos, then the test flight. I will make the initial flight, then turn it over to my 13 year old who has flown several planes, but is not the best pilot. We'll see what he thinks about it. No buddy box this time, just him and the Ez.

I have the CG on mine at 4" from the leading edge which is where the spar is. It looks aft but there is allot of aft horizontal surface so it can handle it. 3.5" might be a little safer but it is really tolerable on the CG range.
Let us know how your son does. Next week is spring break for the kids so I hope to have some nice days for my daughter and wife to do some flying.

I was able to maiden our new EZ. I think my 24g motor must be the 1300, because the plane could barely hold it's altitude with the 6X3 prop and 2s 1300mah pack I was flying it with. The wind was blowing about 5mph for the first flight. It was stable, but no power.

I took it home and cut out a little bit more foam so I could put as large as a 8" prop in it, which is what I think the 24gram 1300kv motor needs (minimum). I was able to get back out later (lunch time) and fly again. The wind was easily blowing 15mph by that time. All the flags are straight out and leaves are being blown out of the trees. I threw it up and up, up and away it went with the 8X6 prop I now had on it. It was very stable in that strong wind and was able to penetrate the wind. I was able to keep it right in front of me with no penetration (just hanging in the air) also. The wing tips were flopping up and down sometimes, but I never felt like it was out of control.

If I can fly it in that kind of wind and keep it under complete control, I know it will be a great trainer in calm weather. I'll try it again when the wind dies down. I didn't turn the sticks over to my son since it wouldn't be a fair test for him or for the plane. We'll probably have to wait until the morning to try again.

For outdoors I think I went to 3s to fight the wind. Indoors it does not take much power. I originally wanted to use a 8" prop but did not want to cut away too much of the fuselage. I am interested in how yours takes the crashes. If it is not a problem then I may update the plans.
I was thinking of cutting down a 8" prop to fit in the slot but have a wider blade. There is not much to the little 6x3 prop.

Mike,
I thought that the fuse might break where I cut it down also. I am going to cut a skewer in half and put half on each side of the fuse below the cutout. That should reinforce it. I am hoping that it isn't too windy in the morning so that I can give it a proper test. I don't have to start work until 8:30am tomorrow, so I will have time before work for some fun.

Now this guy is really cool. Pushers are great. Will have to add this one to the list.
Ken is right about the 6x5. I had the 1300 BW on my T1 and flew it with a 6x5 SF style, (key word here is SF) prop with a 360 3s rhino batt. That 6x5 SF on 3s sure gave it scooting power & didn't tax the motor too bad at all. I would also get more than a half hour on that little 360 3s batt too. Of course the T1 has a much greater lift to it and this was always in very calm conditions and only cruiseing at 25% throttle & usually never over 50%. But you get the picture.
1300BW, GWS 6x5 SF and 3s seems to be a very effective combo.

Looks good Daddy-O. I too was surprised at how stable this plane is in the wind. LT took hers out in about 5mph wind with gusts on top of that (moved the batt forward 2") an the plane handled good even at very slow speed, thats with a newbie at the stick. She got a kick out of bringing it to a hover an letting it hang in one spot, the landing was a little bit tough as the wind was not parael to the paved road so as she touched the ground the plane would be whiped on it's side.The plane has a 7X3.5 prop an seems to have good power for her.

Here is a short video of Jesse the Destroyer flying his new EzFly. He flew a lot longer (about 30-35 minutes total) today, but I cut it down for you. It was a lot of fun, and the EzFly really held up well considering the beating it took today. Again, it was too windy for this plane. The wind has been blowing day and night here for a couple of days now. I need to get out on the slope. Anyway, enjoy the video.

I put a new nose on my son's Ez, glued the foam back down to the cf spar (at the tips where the flopping broke the glue loose), and put some extreme tape going from spar (on the bottom, to the same place on top (running the length of the wing). The last thing was to give some extra support to those floppy wingtips in our windy weather.

It is back to normal, and maybe a little bit tougher. If I continue to get the floppy wingtips, I may cut the wing off and put a blucore wing on there. More testing (and crashing) to come.

Mike, He had a blast with it. He told me later that it was great flying a plane that he didn't need to worry about crashing and destroying. He wants to go out tomorrow morning, but I have to work early. I'm glad he likes it. By the way, at one point he had it flying inverted for about 5 seconds! I couldn't believe it. The wing tips folded down a little bit and it just stayed inverted. It was an accident, but I don't think I could do it on purpose.

How about noise with a BW motor and mid-mount setup? I like to fly at a schoolyard at 6 AM and don't want to get chased away by irate folks I woke up with my plane.

Of course, with the protected prop and EPP construction, I could move to our company parking lot...

This look very good.... but IMO the EPP wing is crying out for a KF section to be added to the underside.. it will stiffen it up and make it even more resistant to the odd cartwheel landing and may even help with the low speed handling

Yep! That is the loudest prop slot noise I have heard in an epp slot. Is the prop really close to the slot edge?

My EPP 80% BA is really quiet. The slot is rather wide and the prop does not go very deep into the slot.

I am making this plane also. I lengthened the fuse tripple 1 inch past the slot for more strength with a bigger cutout for prop. I am planning on a 8 inch prop.

I am interested in the kf wing too. I may try that but would you put the step on the wingtip also? Also would 1/3 of the wing be too much for the step?

Yeah, and he has the throws on that guy at like a 1/4" or less. Very mild set up. He is actually going to let it be used as a trainer. Very tame and stable for that style of build. When he launches it he just tosses it like a paper airplane and she glides real nice. Then just hit the go juice & off she goes.

Lovely looking and excellent flyer that appears to be as close to 100% crash proof as masterfully demonstrated by "Jesse the Destroyer" when he flew it. I have a notion this model may be destined to become a classic and inexpensive trainer.

I will have to cut one up and put it together for my nephew, which BTW, flies almost as good as Jesse...

LMK when and where to send my $$$; I'd probably take two of them.

I just left everything 0-0. It seems to work best with the flat plate foamys.

I have a BW 1300, 8X6 prop, 2s 1300mah lipos and 12a plush esc. It is all working great! I would suggest the BW1500, 7X6 prop with the rest of the stuff the same (I didn't have the BW1500).

You might want to add a KF section to the leading edge of the wing but other than that you will probably be ok. It is not made to fly fast. If needed you can always add some carbon bracing later.

I threw a EzFly together tonight. I wanted to check my fit with the tabs. Man the thing went together fast. I used hot glue for everything but the hinges which got welders.
I also made a page for it so kits are for sale now on my web site. It is the same as the plans except for the tabs. I do need to update the plans though. I found that I made the slot for the motor stick 1/4" too long. I will update them as soon as I can figure out the PDF software I have.

Went to the web page. Three prices are given, "Bare foam kit $25", "EzFly Kit Unpainted | $20.00", and "EzFly hardware kit | $4.00"...

Though it may seem obvious to most, I am thoroughly confused as to what to order.

I think the $20 is just a typo, when added to the cart. Although the firefly is $20...

What size sheet of EEP/Depron are these plans layed out for?

I built my plane last night but I have one question. Has anyone tried the kf step yet? I have not put that on but was hoping someone had tried it. Sounds like a good idea. I will be painting it tonight with a maiden this weekend if winds calm down.

Sorry about that. The Foam kit is $25. The carbon parts, spar and pushrod is $4. I have every thing available on my site (except for batterys temporarly) as separate items. About half of my customers order only foam as they have carbon and electronics laying around.

I meant the length/width ofthe sheet that is needed to fit it all on.

I'm going to build one from 6mm Depron hopefully. Is a 27" X 40" sheet sufficient to fit it all from the plans?

This plane looks great. It reminds me a bit of the frog but in epp (that a good thing). that kit looks easy to build. Can any body say how it flies with that flat plate wind outside. Is it pitchy?. I am thinking on getting one for my son to learn on (he is 8 years old).
Lets keep this thead going.

I have flown ours in very windy conditions, and can tell you it is not pitchy at all. I can fly it just fine in 15mph winds, but it isn't a plane for that kind of wind. I would suggest 5mph or less for fun and good training. That may be less than you would do, but that gives the student the best opportunity at being successful (IMO).

Areyou just using the stock design and components for outside use in light wind?

The only planes that have acted "pitchy" under my control have been those that either had their CG at the incorrect point (in 90% of the cases), or had more than twice the needed throw for proper control on its elevator.

I have a friend who'd rather have an extremely light model than one correctly balanced. He refuses to add weight at the nose when everything else to balance the model has failed. All models of his treated this way are rather "pitchy", one to the extent that it became uncontrollable after take off.

Well i just finished cutting all the foam for thr dragon ezfly and im not sure wich prop to order. On the plans it calls for a 6x3 and on motorheads site i think it says 6x5, which one do you think i should use? Its for my daughter who is in training and im sure i will be flying it as well. I will use a blue wonder and a 10 amp esc on a 2 cell.
thanks Rich

If this goes well I have a bunch of kids who also want to give this a try but im done cutting and will order the kits. I cant seem to keep my blade at 90 degrees to save my life.

Rich, I know that on a 360 3s Rhino, I use a 6x5 SF prop on the 1300 BW. This is on my pusher T1. It flies great and cruises at about 25% throttle. But that is 3s though.
I get half hour flight times easy. Even longer if I just cruise lightly on the sticks.
On just 2s I am thinking 6x5 for sure. Just my opinion though. What kv BW are you using?

Blue Wonder. The 1300, 1500, & 1700's used to come in blue so the term has affectionately remained.
1500 kv is a good motor. I would say 6x5. Amp draw won't be too bad to make you want to prop down to the 6x3.
Hope that helps some.

Daddy-O is right. Even though you are using the 1500kv instead of the 1300, that motor on 2s with a 6" prop may be a bit lacking. If you can fit the 7" prop, it would probably be a good idea. And the amp draw on 2s will not be enough to worry about.

I am actually ordering some 7x6 props to try but will have to open the prop slot a little for clearance. Mine is currently flying on a 6x3 but is way under propped on a 1500 KV motor. It does ok on 3s.

My suggestion for a 2s battery is to use a 7x6 or 7x3.5 prop.

Painted EzFly


Here is my sons painted. He helped me paint it and build it. He is only 6 but is really into it with me. I am awaiting speed controlers from hobbyking and going to run a rewound bw 1500 with a 7 inch prop.

Thought you guys might like picts.
