An excellent parkflyer sized EDF foamie made from well moulded and crash resistant (EPO) foam.
The F-86 EDF jet comes plug and fly ready right out of the box and will take you around 45 minutes to set up. Included is a 20A ESC and small yet powerful 50mm brushless ducted fan system, plus all servos are pre installed so all you only need to add is your own transmitter/receiver and a battery to complete this model.
Flying Weight: 370g
Motor: Powerful brushlessOutrunner
Servo: 2 x 8g
EDF: 50mm Battery: 850mah 3S 11.1V 20C (Required)
850mah 3S 11.1V 20C Your own Transmitter and Receiver (Tx & RX)
You could try it if you want. I would recommend an aerobatic aircraft or a faster bigger warbird. This jet flies pretty fast, and since its a jet its harder to control. You might be able to do it (I jumped from a 3ch cessna to a 4ch aerobatic sukhoi as 2nd airplane), but the airframe wouldn't look so good. Save it for later, once you get good at faster aerobatic aircraft, then go for it and it'll cause a lot less crashes, and more fun. hope this helps! Happy landings!
Ok I cannot give you a flight review as the snow here is coming down in buckets.
I can say this though, the airplane is well made for the price and with the exception of two missing elevator control horns it is good value for the money. I will go stock with this plane. The battery compartment is rather small with other comments suggesting removing some foam to get a bigger battery in there. I probably will experiment as well.
Overall it is a nice ‘*throw in the car with others the same size’* and go flying type of airplane.
The forward half of the compartment under the canopy where the battery is in the photo is approx 85L x 50W x 20D at the maximum. Usable depth is only about 15mm though. Approx 3-4mm can be removed from the bottom of the compartment before going through into the ducting. Other than this it means cutting into the cockpit. Hope this helps!
I'm having trouble fitting a 950 MAH battery under the canopy. Haven't flown it yet, as I've got eh battery space issue, and am now trying to figure out how to get enough weight in the nose to balance the plane. It's very tail heavy. From what I've seen and read, it is not the fastest of the mini's, but 1 circuit and then no power seems to me that there may be something else going on. Perhaps the battery, or ESC.
Dont know if this helps but I had to trim 3mm from the bottom of the battery compartment to fit a Zippy compact 850mah in(17mm thick)
I also used a 24g weight in a hollowed out section in front of the canopy to achieve correct balance with this lipo(61 grams). 360g AUW
Balanced and flew well at the recomended CG. Your right, not the quickest but still enough power to climb and do basic aerobatics though. If the motor, esc and battery are good and the plane is balanced properly Im thinking the fan unit? How well is the fan balanced? Mine was shocking at first and really restricted the motor from unloading properly. Balancing it made a big difference to speed and power.
Firehawks,if i will change the esc plug what kind of plug is it?
and would there be battery that will not make any modification in it?i need a specific brand as well as the battery ratings mah,s,discharge rate...etc?thanks in advance.
look for "CATEGORIES" section at the left side off the screen and click "hardware and accesories" there you can see plenty of edf fan assemblies as well as fan blades in there, just choose what you like of course with 50mm size.
I have a 1600 in mine. I had to cut some foam away under the tray and slim down the front hatch peg but it fit's OK. Most people seem to be using the 1300 and this is a good choice. The aircraft tends to be tail heavy with the stated C-G so the heavier batteries help with this too.
35mm version is way too fast for a gym aswell. Needs above 3/4 throttle just to maintain level flight on 2s and is probably doing 60 km/h just to do so. Turns must be kept fairly wide aswell to maintain level flight. You really need a soccer field for the 35mm edfs.
it mite be cheper to do that but this is a grate little jet i found it is very stabel with a 11.1v 1300mha battery and i get about a 5 to 8 min flite time and i have ben able to fly this jet in winds up to 20mph and not have eny trubbel plus if you add more to your order it dasent make the shipping cost seem so bad
tryed to mount some landing gear off my eflite beast but the gear was to small and the plane didnt seam to fly quit rite with the gear on i just find it best to hand lonch and just belly land on some grass
Please help- I had to add 2, 1/2" washers in the nose to get the CG at 107mm from the front of the wing- seems like a lot. Also, some have written about cutting the rear stabilizers and changing the angle. Others have said theirs flew fine right out of the box. Not sure what to do. I have already glued mine on and cutting them would make them fragile. I have heard the front should be raised 1/8" and another told me to lower the front 1/8" or more. Any suggestions welcomed.
There is a long thread going on about this type of plane on rcgroups . com (remove spaces, links will be removed). Go to the foamy edf section and search for the thread about jpower 50mm edf planes. Ask you question there, a lot of experienced guys
Didn't want to cut the tail, flew it with the washers in the nose. Crashed a couple of times, but the plane took it pretty well. I should have had more experience before I bought this plane, but I am getting the hang of it, longer flights less crashing. All in all a nice plane, fun to fly, glad I bought it.
The CG is bad on this plane requiring a lot of nose weight. other than that it flies excellent out of the box. There are a few other unnecessary mods that will improve the plane but its great for what it is.
I put 41 grams of lead in the front, just caved out a little space in front of where the canopy hooks in at the front. I did not modify the tail plane. The only extra modification I made was to add a thrust tube. It is made out of mylar, just try different diameters until you are happy with the performance.
HK has the stock 5-blade impellers, just not in stock-as usual. There is a 50mm 6-blade fan that is much stronger and gives a little more thrust. Use the Sky Lipo 3S 1300 30C lipo and it will add the extra weight to the nose it needs, with no washers. Don't cut the Horizontal stab, it's fine, swept wing aircraft always fly nose heavy. Go by the CG stated in the manual. I have collected, flown and crashed almost every 50mm EDF out there, and this one is one of the best. i put a 55mm fan combo from ********** and a 4S 1000 30C...Wow what a rocket, and the larger wings handle the torque much better. Only 3.5 minutes though, but what a rush!
If you want to try this on your ESC you took out it might work. Turn on your Radio and put it to full throttle then plug in that ESC. If it beeps a few times then stops bring your throttle back to minimum and it should beep again. Some ESC's want to know the range of the throttle so they self calibrate the first time you fire them up. You should only have to ever do it once. Worth a shot instead of throwing a good ESC out.
Using the stock motor and esc. With a 1000mah battery about 3.5 mins with 1300mah about 4.5mins. (note: that's with mixed throttle usage ie not full throttle all the time.) Leaves enough reserve to go around in case the landing doesn't work out the first time.
Best thing to do it fly for say 2.5 mins check the battery, then work your way up until you are happy with a time that leave a good reserve amount. I usually aim for a little over 10pcnt remaining. That way you get a time that suits your
This plane has aileron and elevator, but no rudder. I don't suspect that you'd use a rudder much anyway even if it had one. I have another larger EDF jet with no rudder, and banking and yanking works just fine. CHEERS!
VERY GOOD!!!!! MUITO BOM O JATINHO VOA GOSTOSO E PELO TAMANHO VOA BEM RAPIDO, TIVE UM POUCO DE DIFICULDADE NO PRIMEIRO LANCAMENTO MAS DEPOIS PEGUEI O JEITO AI FOI SO ALEGRIA , RECOMENDO PODEM COMPRAR QUE E 10!!!!
I would say NO! Too squirrly, hard to hand launch and very fast and directional for a beginner. You want something slow enough so you can think while you fly. Try a Cub or better a tricycle gear trainer.
AS A BEGGINNER I WOULD RECOMMEND A HIGH WING TRAINER,IF YOUR WANTING AN EDF FOR YOUR FIRST PLANE I WOULD SUGGEST A F-15 IT HAS A MID LEVEL WING PLACEMENT ,BUT I WOULD START WITH A PROP TRAINER FIRST ,HOPE IT HELPED
You can use a 3S, 1300mAh, 30C. It is a little more potent than the 20Cs, but this jet needs it, as well as adding some nose weight. Check all the battery makers to get the size that fits the best. Don't be afraid to hack a little foam away!
For sure not, there's nothing to bind on a speed controller. My problem was that it didn't aim, because the throttle range of my tx was too low. So the speed controller never recognized the throttle "off" value. Most controllers out there allow to set the minimum and maximum throttle values.
There is no slide, this is a digital remote control. There is a trim button which is turned off. I never use trimming on electric motors, what for? I can guarantee that the remote was sending a nice 1.0ms signal on the off end, as I have created it by myself and measured it with an oscilloscope. Then again, I had asked this almost two years ago, meanwhile I've solved the problem by increasing the range on the remote control. Still I think every speed controller should be able to adapt the lower and upper limits.
Ok this plane is not an easy flyer, It is so twitchy and unstable you can fly it with your trim settings. It is fun if you like to fly on the edge all the time and it takes hard fast landings real good. I pop the droptanks off on every landing but hey! if thats all that goes GOOD CALL! I have done MAJOR mods on mine that makes it a way better flyer now I will post all I have done soon.
I think the best mod you can do is cut through the front half of the horizontal stabs and re-glue them up about 3-4mm so the angle of incidence is flatter otherwise the plane wants to fly nose up. I can fly my jet with the stock battery 850, 1000, 1300 and 1600 mAh 3s, just made some extra room under the canopy. I fly it with the wing tanks and put a strip of F/G tape on the base, I also changed the elevator servo to a HXT900 and wires to a thicker gauge and put carbon tubes over the straight section of the aileron rods to stop the flexing... My fan was unbalanced badly also. It's no speed machine but it flies well, give it a good throw to get it going and it doesn't mind a little wind!
I had an issue with my EDF out of the box as well. One blade rubbed casing badly, and another slightly. I didn't want to tear the EDF out, so I opened the hatch so I had some access to both sides. Got a small piece of sandpaper that fit between the blades, and held it at an angle against the casing and turned the blades from the other side. Took quite a while and patience, but now neither blade touches the case, and the unit is balanced really well**no vibrations at all.
Bought a spare wing to build another but it's got about 5 degrees of wash-IN on each wingtip. Put it in a jig to twist it straight & left it in my hot car for a couple of weeks last summer. Stayed straight for a week before the memory turned it back into a potential tip stalling SOB again. Are they all like this ?
Mine came in four days from HongKong to the UK which was quick,the build was really easy and a good manual so i would have to say 4 stars because my tail was dented a bit but i just sanded the paint off and soaked it in hot water and job done,keep up the great work HK.

Quick delevery from HongKong to UK (4 days) build was so easy and the manual wasn't to bad as i've seen worse,only 4 stars because mine did have a tiny dent in the tail part but no biggie as it's all sorted now,i have read pepole saying the battery didn't fit but mine was fine so i've just got to maiden it to see how well she flies.

well i bought just the kit. final setup: i cut the foam inside and put on it a 64mm ducted fan with 4300 kw , 40 amps speed control , 2200 11,1v battery and i make a modification to the ailerons:2 servos one for each aileron and cutted the foam on the back to place them . the receiver will be placed on the front of the cockpit. the planes fly well and very fast about 100 km/h.

Received it with a damaged canopy. Looks very scale in flyght. Easy to fly, not very fast. Loops and rolls without any problem. Electronics is OK.

Well my first edf and purchase from hk...... Not bad for the money... Very fast and not so easy to launch, and watch out for a stall... But putting all together was easy... Lots of fun... Wish it would fly for longer than 5 min.. Nice job hk.
