Ellipso Aero's -WARNING! These models are to much fun. Use Caution, Highly Addictive!

I don’t think that I’ve seen any model on rcgroups that has had as many versions as the Ellipso Aero and what a great model to modify. This attractive little foamie has great flying characteristics. It’s fast when you want speed and slow when you want slow, while always having controls that respond. Capable of most aerobatics without any bad flight characteristics. It’s simple and quick to build. Even a beginner builder can manage this with very little cost, but great fun for the experienced builder as well. It flys really great with a small motor. You do not need to over power this plane! I believe it would torque roll out of control if you did. The auw is only 15oz (Light as a Slow Stick) and has all the power it needs with a small motor. Many have been built with positive results (see the reviews below) out of many different foam building products, so if you’re looking for a fun to build, and fun to fly model, consider one of the many versions of the highly addictive Ellipso Aero for your next foamie!

Im extremely happy with it. It took minor trim, like one click down and one click left on the aileron to make it fly just about perfect.

I heard neighbors blurt out, crap look at that. all I can say, is this is the best high wing flyer Ive made yet.

I let it run across the grass to test out the wheels and they worked.

I then give it some power and gave it a hand toss...it flew out pretty good, had to give it a click left on the aileron and a click or two down but other than that, flies great....landing went very well.

Had a family dinner today, took the biplane out to show the nieces and nephews and their dads....I felt froggy and went for broke, doing inverted, and all kinda other funky aerial manueavers I dont know the names of, I was sweating when it was over, hope noone noticed but everyone was impressed with the plane.
I would say all in all, that was a good day. Thanks to Daltons inspired designs.

Nothing serious, take off, left turn, right turn, figure eight, a loop and landing. Do this every day......

So thanks for the EA...

Dalton - certification could not have gone better. Actually had one of those rare "perfect" landing.

The guy that was the instructor was pretty impressed with this plane. Kept saying, Wow - that is scratch built - wow......

She flew great, nice and slow, no trim needed at all. 3/4 throttle makes her disappear straight up w/o hesitation and FAST. I somehow wound up with an incredible amount of aileron throw and so had to cut it down to about 50% to make it a bit more fly-able. Even so, rolls were tight. Loops were so tight I was afraid the prop would catch up with the tail . This plane turns on a dime... very nice.
Great plane. I'm glad I built this one... It's a keeper.

Dalton, Thanks for sharing your designs and taking the time to post plans and support everyone's builds!
I forgot to mention...
The plane managed to get the attention of a number of by-standers. The fact that I could hold a conversation and fly this plane at the same time shows how nice and stable the plane is. Once I landed the plane people were amazed that it was scratchbuilt from DOW fanfold foam and running electric. After answering many, many questions I sent a few people home to their computers with the URL to RCGroups and directions on how to find the thread.

It was that irritating type of wind that keeps fooling you into thinking it's nice and steady, but once you get near the tree tops there is so much turbulence and gusting that the plane gets tossed here and there. I adjusted the battery to bring the CG to between 30% and 35% of the chord and tossed her up (no landing gear), a bit nose heavy for aerobatics. Well, she did very well dealing with the wind even though the wind was trying to ruin my day. What scares me on windy days is not really the flying, but landing. Even though there was quite a bit of gusty turbulence, the big ailerons on the wing were able to get her down nice and level with a gentle landing.
I went back out towards sunset with no wind and man was it fun to fly. I flew through two batteries before it got to dark to see orientation and had to stop flying. I may have to start decorating this plane. She has earned it after a few good "missions".

I spent a good ten minutes shootin this thing towards the heavens till it was a spec, then let it glide back down...then spent another ten or so seeing how fast I could get it to go......moral of the story, it had very nice flight time. Anyway, I love this thing.

I realized today that I have to make up cards with all the info about the EA so I can hand them out. Here is a quote "You can tell it's a hand built plane by how well it flies and what it can do".

I have already found out that it will fly great inverted, but want to tighten up the loops and rolls. Actually, this is the 2nd of many planes I have built of blue foam that is consistent in take offs and landings, and seems like it is always in my control. Thank you, Dalton for a great design. Carl

I also want to built the round top biplane that you designed, but haven't found what motor you put in yours to make it fly so nice. Could you fill me in on that? About what all up weight did it come out to? Since I am 81, I like the slow planes, and can keep up with them better. Thanks for all the help you give me and the many others that write in to you. You a credit to this great hobby, and make it possible for others to be successful at it. Thanks a million. Carl

It started as 32" version. The AUW is 235g 8.3oz and the thrust more or less 400g 14.oz with this motor and prop. It was built with 4mm from pizza trays and for first time I avoid using hot glue to save weight.
As I said before, very happy with it, thanks Dalton. Gino: Taubate,SP,Brazil

Maiden flight went surprisingly smooth and I soon realized that flying with ailerons was not as difficult as I expected. So I'm looking forward to geting more flight time with this EA and gaining confidence with ailerons. Thank you, Dalton!

I don't like to wring em out on the first flight. Usually after 2 if nothings cracked or trying to come loose I givemhell. Came around to check the stall speed, it's really low and no wing tip drop. That's great for a low winger. Second time around I put it down right where I started from and power rolled right to my car. Nice. Dan

Your plans of the Ellipso Aero was my first scratchbuild and I'm still enjoying every minute flying it! Also noteworthy are your other creations (Ellipso Lite, BowStick, SS Spider, DangoStick, BiStick). Just from reading your posts I can tell that you are truely a hellava nice guy with a flare for aeronautics!

It's a good flier. Stays in whichever direction you direct it and doesn't seem particularly affected by light winds (not tested in heavier winds). It also glides surprisingly well and keeps good speed at full throttle. Thanks for making the design available. Merlon: Norway

But as from the start, the ellipso is hands down my favorite plane of this type, its just flat works.

Is this prop too big? Am I drawing too many amps? I am going to order a watt meter, but I was hoping to get some of your opinions. By the way, the plane flew great (thanks to DaDesign for the Ellipso plans) until the motor flopped off.

Id been getting it up real high, then cut the throttle to 1/4 or so, let it slowly decend....well...I decided to cut the throttle completely once, and realize, it glide so slow its not even funny....breeze come along it seemed stuck in the air, like it was never gonna come down.
Was alot of fun...does what I hoped it would.

It was disappointing that I did not have a second battery ready. I can’t say enough about the landing gear design. The grass was to high and the wheels to small but the worse that happened was popping the gear out of place on the controlled crash-landings. Jerry

Nerve kick in, left stick, right stick, left stick, there a gap between the two backstop on the baseball field. Go for the gap. I'm sure glad this plane have great flight characteristics. THANKS for posting your plans for the EA. She is a joy to fly!!! ( NOTE: BUY MORE BATTERIES.)

But to accomodate the battery, I built an enlarged "cowling" where the lipo fits snuggly. Other than that, this was almost the same as the EA Mamba with a different color scheme. All parts and electronics were used from the damaged EA Mamba so it was a fairly simple build!
I had the day off today and took my new EA LW out for her maiden flight. (Sorry no video or photos) She was an excellent flyer with little trim and no crashes! The KFm2 made a huge difference and I'm thinking that maybe the way I built the "cowling" also provided some stability like an airfoil step for the fuselage. I didn't really need to push her beyond half throttle except for loops and rolls which she handled quite well. But she is solid and light enough to take full throttle like a little rocket!
Thanks again for sharing the plans and keep the mods coming! Steve

I always wanted to learn how to fly and figured why buy one when I can build one for less and also have the pride in saying I built it too. I'm doing all this off of my smartphone but ill try to post sum pics and vids of me having a great time with my new toys just like to say thanks for such an awesome plane

Inverted low altitude passes were a breeze.
As I was alone at the field I did a few take off's directly from the table. Didn't manage to get any successful landings on the table though as the plane always rolled over the edge...
I had a blast and I'm already planning for a couple more Ellipso's in my fleet so I think you have really created a winner here Dalton!

Thats the beauty of this plane, even though I had a very rough landing (crash) all it will cost me is one dollar for foam and some time to be back in the air. Top

But anyways ive held on to the i believe its the 28" version i built like 2 years ago...flew it a half dozen times then got into 3d....then jets....now i just wanna go fast!! When i flew this one made from 3mm foam and taped everything then a shiny paint job...i noticed how fast was and how long it would glide.....well i put 2 and 2 together and i just re-maidened it and holy cow....its fast!! Auw with 2100 mah 30c bat and parkzones 2200kv motor for the f27q stryker is 19.2 ozs....no landing gear yet though.....from the videos ive seen of that plane in flight.....i bet u my plane that the ea is just as fast!!....no joke....i bet she does 85 in level flight!!

Looks like fun!
How about some electronics facts, please?
Motor, battery, servos, ESC, Rx.
Looks like removable gear and wing, eh?
I might try this with a little camber to the wing.
Have you built and flown the low wing version?

Thanks,
Walt

Another very clean design. I think you should try a kf airfoil on it. Dalton you design great looking planes.

Now that is very slick there D! I would be very tempted to do a KFm4 Version of that wing with 40-50% as Dean mentioned. Since this is a bit more of a 3D and more speed, the 4 is the right fit with the step on top and bottom.

Cheers

Dean, Thanks for the kind remarks. I really really appreciate it. djacob, Have fun with it. Ron, Thanks my friend.

Hi Walt, Thanks for your interest. The eletronics came from bphobbies.com, GraysonHobbies.com, rctimer.com and other hobby suppliers. Shop around for the best price.
The motor is a BrushLess or BL-2212-13, The best price I found was here.http://www.rctimer.com/index.php?gOo...8&productname=
The ESC is a generic 20A from the same place.
The battery is all my batteries from 1320 to 2200, some ThunderPower and the others are generic from Hobby City
Servos are Hitec HS55 that I got at the LHS
My radio is a Spektrum DX7

The reason I ask about the low wing version, is that I want to train on the use of ailerons. I tried a high wing plane and the adverse yaw is tough to compensate for when you are a newbie (assuming that I can EVER learn ailerons )
So, how is the adverse yaw on the high wing version (it isn't really VERY high)

Oh, interesting - I didn't notice that it didn't have a rudder.

How I cut out foam airplane parts quickly

I know there are a lot of different ways to do this but this is how I do it. I don't mind using a few sheets of paper and a little printer ink. I never trace patterns! I just print a new plan and repeat this method.

Hand Launching the Ellipso Aero

Today the grass was high and we were in a fairly small space so we decided to hand launch the Ellipso Aero. It performed like a champ. I did it without help and it was simple to do. Here is how you can do it as well.

Set the control throws to neutral. Grip the airplane near the CG, apply about ½ to 2/3 throttle, and throw it moderately hard straight ahead and slightly nose up. Keep your hand away from the prop. Slowly increase throttle as soon as the model has gained some speed and altitude. It's important not to launch the Ellipso Aero at full throttle, since propeller torque can cause it to roll uncontrollably before it has gained enough airspeed to counter it.

The Ellipso Aero is very smooth and predictable, it has a moderate speed range, and it's capable of graceful aerobatics. Landings are straightforward, but it's very important to return the elevator to neutral just before touchdown to prevent the elevator tips from digging in.

Have fun flying;
Dalton
