Bounce into trees, cartwheel down the runway and screw up every takeoff yet still be able to continue flying! Thats what this 3D plane is all about. Made from super resilient EPP foam, its even more flexible than normal foam and can handle impacts without breaking! Fuselage made from 2cm thick EPP foam and has an Aluminum insert, Wings & Elevator have carbon fiber inserts which makes this plane really very unbreakable!
This ARF requires a motor, servos, esc and prop. Also needed is your own receiver and battery to be flight ready in under 1hr.
Can someone with lots of 3d experience tell me the best set up for this I don't want it under power
Motor ? That won't fall apart read some reviews
Esc?
Servos?
Batts?
Prop?
I added this to my wish list. Sort of a plane you can bash around have fun with it and repair if you screw up. You could use it as a trainer if you put the throws to min and your radio has rates/expo settings it is real easy.
Electric Power if you know how to fly and want to go on to Low wing it will be good. BUT if you are a newbie then every say start with a Hi Wing. I hope this helps.
EPP foam in any real hobby shop Cheaper to pay their price than have HK ship it. I have an Angel that uses EPP foam but the thinner stuff. Rebuilt my whole plane in about an hour and it is still flying 3D
if you buy the EPP foam and still order the plane then trace ot out BEFORE you put it together. If you buy the foam then go to ( RC Groups 500 plans) you can build your own plane just like this. We have home made foam planes we fly all the time total cost in the air 40$ , Fix in 5 minutes with epoxy glue or hotglue if you crash
I need a bigger engine. does not climb vertical very well with my 3015-7 470w TowerPro and 11/6 prop.
I want a bigger engine. Strong. preferably 3 cells lipo. What do you recommend? And what prop?
Our H1210 EPP-3D flies beautifully with this engine. It hovers very easily and climbs away on an APC 12x6 propeller and a Rhino 2250 (30C 3S) battery.
The motor magnets did fall apart and jammed the motor initially though until we poured some "superglue" over all of the magnets inside. Now it works flawlessly. See some flying on YouTube. Just Google : Red Eagle Model H1210 EPP-3D Foamie Fun
My magnets fell apart too! Not a very good engine. I glued them back together. And the engine works, but in my case there isn't enough thrust to hold ahover very we'll, let alone climb vertically. Need a different engine and prop.
I bought an E-Flite outrunner 15. Great engine. Plenty of power. I broke my plane so I put the engine in a Scanner (1.4m wingspan) plane which weighs 2.5kg. Fly's great.
Withc brushless outrunner do you recommend for this bird? Will this one be alright? http://hobbyking.com/hobbyking/store/uh_ viewItem.asp?idProduct=7125&Product_Name=TGY_Aerodri veXp_25_SK_Series_35-42_1000Kv_/_605w
It should be fine, it is the recommended motor for the plane and is the one I will be using when it arrives, while waiting I am using the non SK version with the same specs.
Will be experimenting with props, a 12x6 should get around 2000grams thrust but also want to try a 13x4 for less torque roll. Mine is 3/4 built, will hopefully be in the air on the weekend.
I am doing a build log and then flight report in the forum - www.link Dave.
That motor is what I am using, it is good power and comes down cool. Even took a couple nose-ins and still ticking!!
I am running with 3s 2200 and 3s 3000, had a 40A esc, switched to a 60A to try a 15" prop, which went very well!!
Well stock levels are continuing to drop, anyone got theirs yet? Theres a good thread on the equivalent Red Eagle supplied kit on rcgroups, seems they have gone through a few revisions with the size of the carbon spar and alloy tube up the fuse. I bit the bullet and ordered one last night, so will find out soon I guess!
Plane received - it is the later version Red Eagle model, with the larger (20mm) square aluminium tube up the center of the fuse and 8mm carbon fibre spars. Very nice big foamie and fuse is quite stiff to give a good rigid airframe. Building about to start and have a build log started in foam section of airplanes on the forum.
Build completed, all up flying weight including battery came in at 1169 grams. Thats with a TR3542 1000kv motor, 12x6 APCe prop, ZippyH 2100ma 30C battery, 4 x HXT MG-14 servos and a $pektrum 6100 receiver. Very happy with that. Maiden flight yet to happen, will submit my findings once I can get out of the house in daylight hours :)
Went for the maiden this morning, one click of down trim and two of left aileron and its sweet as! There was not a breath of wind at 6.30, got 4 batteries through it then chucked em on charge, but by the time they were charged a 15 to 20 knot cross wind had picked up - so flew another 3 batts just for the hell of it!
Bit underpowered though for my liking, but I didnt end up with the SK3542 1000, just the normal gold 3542 1000. Might be a little bit less grunt than the SK perhaps? Only pulling 28 amps static with a 12x6 prop, only had a 13x4 with me to try as well and all that did was slow it down, but did enable it to climb vertically at least. The 12x6 was just enough to put it into a hover for a few seconds at full throttle but not enough to hold it there.
Will have to grab a 13x6.5 and maybe a 14x something to try as well.
All up though very "happy" :)
I have gone for a higher KV motor, the HXT35-30-A With a 8x6 prop which pulls around 40A. This should be plenty of power for it. Will have to wait though, on back order as always.
*daniel_L I run PA Thrust 30 and Quantum 45A ESC in Extra 260 on a 3S setup and in my PA 58" Extra MX I have a Thrust 50 with a Quantum 65A ESC and fly it with both a 6S and 5S setup. Amazing planes.
Here is a video of the Happy EPP. All these EPP models were originally made by a Japanese manufacturer "Hokusei" http://www.youtube.com/watch?v=2SeC-jWK zmY
I am discussing it because I like it and eventually will buy one. :-)
I was suggesting that originally these were designed by Hokusei. If they are made by Hokusei for Red Eagle Models or HK then it would have been expansive but much better. By saying this I do not mean the the current offering is not good quality but Original is always better and if it is Japanese. :-)
I'm still not clear on what you are saying. Are you saying that Hokusei were making EPP kits before Red Eagle Model and other manufacturers, or are you saying that the Red Eagle Happy was designed by Hokusei? Red Eaqle Model is a relatively new EPP plane manufacturer. Hokusei have been making EPP planes for much longer.
Scott, No chicken first, egg thing first here. Whenever I see a model like this it reminds me of Hokusei EPP planes and it attracts me too much. I do not know who designs and supplies these EPP kits to HK but they look like Hokusei Models and since Hokusei is designing this way before than others so anyone who sees this will say the same like I do.
I have one of these and its AUW is 1300g with 4 MG14 servos, Turnigy Plush 60A ESC, Turnigy SK 3542 1000kV motor and Rhino 3S2150 25C lipo. Red Eagle's AUW weights on the smaller planes seem to be without battery so I'd guess it's the same on this large one.
Yes, the PA Extra is under 1 kilo RTF, but what will it look like after cartwheeling it down the runway?? These are not in the same class so shouldnt really be compared.
My current favourite in my fleet is the Red Eagle unbreakable Yak54. If this is as good as it, then I might just have to grab one for myself.
An EPP unbreakable foamie with removeable plug in wings! Gotta love it :)
yes this is the Red Eagle Happy. The forum that Slumberjer refers to and the "unbreakable" broken happy was mine. I bought it from the another site. The one I had was the first gen. It had smaller carbon fiber rods down the wings. The second gen is better. I haven't gotten mine second one up yet but one day i will.
*Seacomms - the wing is not removable. The instructions say that the wing is to be glued to the fuse. It is not unbreakable but can handle quite a bit of thrashing.
With the deep flat fuselage, it looks like it would knife edge really well. I'm tempted to get one, but I'd have to try flying it as a glider off our local cliff too. We have more high wind days than calm wind ones. Doesn't look like the nose would handle a folding prop without a lot of modification though.
I calc the recommended gear at about 570 grams, plane itself, wings look pretty chunky, at a rough guess, I'd say almost 45mm thick at the tip, possibly more at the root? If you look at the end of the wing picture, looks like there is a low density core, and a high density EPP skin bonded on. Adds up to quite a weight of EPP, and then there's the carbon spars. The ailerons and other control surfaces appear to be sheet, no taper. So, there's some room for performance improvements, but it does look robust.
The aileron, rudder and elevator are actually sandwiched structure, with EPP sheet on surface and KT board as core. Feels pretty stiff to the touch.
Now my question, will it be wise to film cover the wings? it just feels too soft and fragile with the thin epp sheet on plywood ribs.

3 thumbs up!
Just received mine, and although a little battle scarred from its flight down under I am very impressed. Its just a bigger version of the other Red Eagle unbreakables so quality is good (it's HUGE!!). Its not branded "Happy" like the originals (which I like). Its the version 2 Red Eagle kit as well, stronger wing and fuse spars. Quality excellent and from others I have seen flying flys very well too. Build review in the forum under Foam Aircraft

It's a very good basic 3D flyer. Very good value for money.
BUT! It's heavily underpowered (won't climb vertically very well). Ailerons are not very sharp and responsive. Suggested servos are OK, but hinges must be strengthened. Instructions are not that good for a beginner (get someone who has built several models next to you).
It takes about 2-4 hours to complete construction if you are semi-experienced. Some modifications are needed to the model during construction. If you want all the building tips, do's&don'ts - feel free to Email me at leelaster@gmail.com. ALL IN ALL - VERY NICE - LOTS OF FUN - GOOD VALUE - NOT A PRO 3D MODEL.

Good value for money. Quality could benefit from better instructions and more accuracy in cutting the parts.
Performance: it's a 3D trainer, Not a Pro 3D so do not expect that. The airframe is too soft to perform accurate stunts. The model is vastly underpowered. Requires a stronger (over 550w) engine and a larger ESC as a result. Servos recommended are OK but the hinges are too soft (need strengthening).
Build time: 3-5 hours, but as the instructions are not that good - get an experienced builder to help you. CG is exactly 1/3 of the wing from leading edge (for suggested spec)
OVERALL: A good 3D trainer for beginners. Nice material. Fun to fly.

Received from HK in late Sept 2011. I have almost completed assembly. Used mostly "UHU POR" glue.
Here are the problems I had:
- Holes for tail spars still wrongly drilled.
- I had 3 wheel collars, all for 1.8mm. Two of these are needed for the tail wheel, one to retain the wheel, and one to put the load onto the black plastic holder.
- I had ZERO wheel collars for retaining the front wheels. (3mm)
- The upper-most bend of the front wheel struts should have been longer. Needed to cut foam so that the wheel struts could be inserted more into the the aluminium.
- Manual is too brief. Kit doesn't fit perfectly, lots of time, patience and improvisation is needed.
- The wing is EPP skin wrapped over foam and plywood framing, it *feels* much more fragile that I like... but I have not flown it yet.
