The Skyfun can be used by novice and advanced pilots alike. With a maximum speed of 100km/h and a slow stall speed, the Skyfun is a park-jet you will want to take everywhere. Made with high-pressure EPS and a polished mould, the Skyfun is extremely stiff, has a gloss like surface and yet very crash resistant!
Hey guys. I bought this plane a couple of months ago and haven't getting it to fly properly yet. I have flown with it though, but crashed 3 times (and every crash cause severe damage to the main body, but should have been fine after gluing). And im not a novice pilot, flown a bixler with aileron for a while, and other planes and helicopters before. Nothing as fast as this, but definitivly not a novice.
The mixing is properly set up with elevon mixing, and we've checked the servos on the ground. However, when I get up in the air, it's totally unresponsive. It obeys some commands, but far from everything which makes it impossible to fly.
Im using a turnigy 9x Tx/Rx, and the receiver shouldn't be the problem, as it's working fine on my quad.
The motor is a Turnigy2836 2350kv
Servos are two HXT900
ESC is a HK blueseries 40A, and battery 2200mAh turnigy 3s
What are your control surface throws at? it almost sounds like they are not getting enough deflection. Try setting to max throw and try. Also use the duel rates on your TX in case it is a little too responsive. Maybe aim for adding 30% to what you have now. so if they (elevons) deflect 1 inch now, make them move 1.4 inch or so.
Um... James you do realize those things sticking out the side of the body are called wings?? and that jets don't have propellers!! It's really a lifting body, or a delta wing, we all know it goes fast but can it fly relatively slow? is it good for a micro recorder FPV set up does it have a high speed stall like a jet???
I want to use it for training for high speed but I need slow speed to start off with, I think "Jet" in it's name means it performs like a jet but like you say the lifting body should have some slow speed properties? look at the space shuttle it's shaped like a brick with wings and it glides!
I'm just interested in air time not speed, can it glide slowly? can this fly slow like a bixler?, and could you fit in a 2200mah 3s 20c I don't mind cutting, (saves me buying more battery's) and how repairable is EPS?............. thanks for any help.
what is the difference between this model and EPO ParkJet MkII w/Outrunner this is the link on HK: http://www.hobbyking.com/hobbyking/store/__13 763__EPO_ParkJet_MkII_w_Outrunner_ESC_Servo_V_tail_M ixer_PNF_.html I'd like a model more faster than ms composit swift II without motor on sloap soaring with 8-18 mph wind and possibility of slow fly (not a jet but more faster than ms composit that it was realy good on sloap soaring .I would like a faster model with more wind . the ms composit with more wind and no engine is too light and small
I agree with Andrew , one of my first planes was the skyfun and I trashed the hell out of it. I then dropped back to the parkjet and was able to start to get the hang of it. The park jet is faster out of the box but has alot less weight so is more for giving when crashed ( I do hate the motor mount for it and actually changed the one from my skyfun into the parkjet. I have pimped both up and the parkjet is somewhat limited in what you can do to it. Also being smaller it gets really small really fast when you speed it up. The skyfun loves an upgrade and handles the extra weight easily. I tried the recommend parkjet 160km upgrade but it really struggled. Where as I was able to get my skyfun to 210 km without an issue. hope this helps.
Ive been flying this set up for well over a year , the only issue i have come up against is the mount mount an base mount, if your handy with a few tools a piece of 2mm x 50mm x35mm aluminium fold it up an youll be sweet to go,cheers
Does anybody know the type and size of the screws that hold the (MOTOR MOUNT ON).. Not the motor to the mount but the screws that go through the plane and hold on to the mount.. Mine fell out while flying and i need the size of them... Please help
Bit confused here. How many channels does it have. I see the throttle and ailerons, but what about the elevator. Or do you have to do a mix in the radio. Sorry if it sounds too elementary, never had one of these.
Hook up your servos and set up the model in memory. First job is to ensure correct direction of movement - use Servo Reverse if necessary. Then mechanically centralise as best you are able. Follow that by adjusting servo travel after you have used your sub trim to precisely centre up. The actual mix can be adjusted at the end. Various models also have different Dual rates and exponentials. Go for what is in your instruction booklet at first. We have a few chaps in our group who fly with no DR or Exp and simply use the raw wing mix "out of the box" with no problems. BUT they do have well set up aircraft with good up thrust and exact CG.
Can anyone tell me where the CG or CoG should be for the skyfun in its stock configuration? Im ballancing somewhere in the front half of the finger holes, but it will not trim within my tx's trim adjustments. Thanks in advance
This aircraft has a tendency to nose in on powered hand launch so do get your CG spot on. It can accept a CG further back but if too far will lead to difficult glide control on landing. Ensure you get the prop up thrust angle dead right for best performance.
You could use the turnigy 2836-2350kv on 4 cell 1850mah with a 4,5x4,5 prop (60A esc is enought). More than 100mph you will get. If you prefer to use 3 cell setup you could use the turnigy 2836-3200kv version with a 5x5 prop. Check this video on youtube: ***.youtube.com/watch?v=Vgh-G6MkUNs
I have not come across one on HK, yet. But I recollect seeing suitable wire - you could then make up your own cutter. A number of books and sites discuss how to make one up for yourself. Heaps of different ways. Or you could buy a kit which you assemble yourself.
To my knowledge, no exact spares on this site. But check the AXN Floater jet motor assembly. That could be adapted for this aircraft. In addition, consider the common stick mounts available on this site in many forms - plastic and alloy. Consider fitting it inverted. Before you start you might find it handy to make a little cardboard jig to fit the present upthrust angle so that you can replicate it in your new set up. Whatever you eventually use, you can always fair it in a little using the thin construction plastic sheeting or light foam block etc which can be spot painted white or even covered in whitye insulating tape. I would consider making my own mount incorporating adjustable thrust adjustment to obtain the precise trim for perfect flying.
Good value? Depends on more than just the model. Sure, this aircraft flies well. It looks good in the sky and is enjoyable to fly. Locally, we had some concerns about noise annoying residents near our park so we repowered with a quieter motor. If noise is not a problem for you, then you'll be okay with the power plant as supplied. But next comes the problem of postage costs. The packed kit does not weigh the almost 2 kgs cited. If you include some other items such as power packs etc you are into the next weight category. This more than doubles your cost in US dollars before you apply your exchange rate. Add any local taxes then compare with your local hobby shop which will not charge you for more postage if you have any problems. There are risks of damage and consequent inconvenience which are acceptable if the product is priced much cheaper than local. In conclusion, at this price and at the weight cited, this aircraft is sadly not a good value kit.
Hi, What is the stock Prop if this bird? I like the stock setup, cause its chill and I am learning the fast jet style flying... I want to oder the stock prop and a prop that can give me a little more speed? with the stock MOTOR/ESC of course.
I would like to know :
I have 2200 mAh batts, and wondering if I buy this jet, can I run the jet STOCK with a 2200 mAh?
I also have a 30 amp esc, park480 outrunner motor, maybe it can be a nice upgrade ? Is the park480 will fit?
Yes, you can run/fly this with 2200 battery with stock equipment, just give it a decent throw when launching to avoid stalling. I'm not familiar with park480 motor, but for me it sounds like installing it would be a downgrade instead of an upgrade.
yes bloke you can use this battery ,an the power system you have maybe slightly under powered due to the carrier capacity , most Skyfun flight weight is arounded 700g's including battery, you motor is capable of flight weight of 800g's, so you can only try ,see how ya go, best of luck, cheers
in my plane I have, 1800mAh battery, a controller 30A, a motor of 3200 kw, and has a flight time of about 10 min.Aprox and speed> 200 km / h

Plane too boring with the stock motor. Only one flight with stock set up. Hooked a turnigy 2632/3400 and a 40A Super simple ESC with 4,1x4,1 prop and 3S 1550 Zippy bat. New motor fits perfect in the stock motor mount and flies pretty fast now. Will try 4,5x4,5 and 4,75x4,75 , I think the motor can handle them. I had to replace the shaft of the motor as it broke during ground testing.

Stock motor small but ok. I put the Heli 4500kv motor and the rcd 4.75 x 4.75 with a 60amp ESC plus a BEC with a 40c 1850 pack. I forgot how much I could tremble on a 1st & 2nd ballistic missile test flight. Yes it is fast, loud & impressive enough for whole club to go Wow. goes vert on 50pcnt. next is twin motor. currently about 140kph. X2 should be up around 200kph. plane balances nice with a 1200 bat pack. bigger sends bat way back. glide is AAAplus
