ZH YAK-54 EP 45inch ARF Laser cut ply & balsar. Includes mount, carbon fiber tubing and accessories. (some not shown in image) Amazing construction and ultra light design make this a really nice plane to fly. With a 36M motor and 1800mAh 3S1P pack this plane will hover on 3/4 throttle.
SPECIFICATIONS Wingspan: 45.5inch Fuselage Length: 40.9inch Wing Area: 403sq.in Suggested Motor: 36-12M Suggested Battery: 2200 ~ 4000mah 4S1P Recomended ESC: 80A Suggested Prop: 4cell:14x9 / 5cell: 14x8 Weight of kit, on the scales without motor/esc/battery etc.. : 715grams
Flight/Build Report. Yak54 comes with nice instructions (including pictures and decent english) as well as a full set of hardware. Control horns are not fantastic, though do the job. Apart from the control horns, this kit is A-grade and of very high quality. Assembly went together easily, although we beefed-up the engine mount with extra epoxy. We chose the KDA35-12L motor with the HXT036 esc to power this plane. HXT2200mAh 3S1P lipos were used as the power source. GWS Park servo for the rudder and GWS Nano servo for the Elevator. Ailerons need 1 servo each, we used the 9320 servos for this. First flight was more than exciting as the plane took a nose dive, but quickly recovered. A quick landing and change of CG as per instructions, and the Yak54 was off again for another flight. This plane flys extremely nicely, and very quite with the KDA35-12L on a 11x4.7 thin e-prop. Unlimited verticle and a very snappy knife edge and snap rolls, thanks to the pull-pull rudder system and large throws on the GWS Park servo. Landings need to be gentle, as this is a light plane.

Postage weight appears heavy due to double boxing of product. We are aware of how brutal international postal systems can be. Thats why we double box every plane, to ensure it arrives in the same condition as it left the warehouse.
I am putting together an order for this plane and everything needed for it. Can anyone tell me what size servos are required? I plan on using a 35-48 900 kv motor, turnigy plush 60 amp esc, and a 2200 4s lipo. Thanks.
i have this plane and i have hxt900 in it but thay are to small for the mounting brackets had to add some wood to fit.i have the motor and battery u are planning to use. that will pull the **** out of that plane but it will glide like a brick. With that setup u will need power on at all times.
sorry man i think i got on your comment bar somehow i was trying to just make my own comment i wasn't trying to respond to yours as I don't own one myself and know little to nothing about them lol
Ha ha ha ha I love the scheme on this little yak. It's almost exactly the same one as my (dis-continued) Goldberg 67" yak54. This would crack my buddies up when I showed up with the "Mini-Goldberg" lol I would definitely get one if I thought the power system out of my 1200mm Dynam mustang with an upgraded(45 amp) esc and running on 4s would pull it good enough. I know it will give my 40 ounce mustang unlimited vertical climbing power but that's also with 9 gram servos and a total flying weight of 40 ounces so I'm sure I would have to keep it light
hello friends, I am new to the site, I wonder what I need to fly this plane because I have already have tX / RX, many told me of various configurations, but I can not find the codes of the article to make the HobbyKing buy, someone could help me .... This plan can be used with electric motor
_S3ti yes yes yes. Mine is perfect. If I have some more funds I will post a VIDEO. I should be out of BK soon. I have 3 and they have changed a little but basicly the same and better and lighter. But one is not enough really
inside, but the fromtplate is verry weak!! be shure to glass the Frontplate (there where u screw the Motor on) or make it stronger with a second sheet of Wood. The Plate where u screw the Motor on will break easely also just from vibration. Or order the alu Motor Mount with the kit. So, the Motor wil both ways be inside the Motormount. Please Credit if this was helpful. Thanks.
No they arnt, you have to glue the ailerons and the Rudder with some paperlike hinge in Place but its easy and fast done, the Hohls for the hinges are done by the manufacrturer. so all u have to do is to glue the Parts together. Hope this was helpful, if so, Please credit me. Thanks
i got a plane exactly like this with no instructoins or specs. the motor mount seems to be diffrent but it has the same wingspan and i was wondering where the cg was. also mine uses a 36 amp esc and a 3s 2200 that the guy told me to use. so is this the same plane? please help!!!!!!!!!!
Cant tell you this right away from your discription, if you could tell from wich Brand the other Plane you speak about is, so perhaps someone can try to tell this from the Pictures. Beside: I did own this Plane (befor i lost it) and i flew it also with a 3s 2200 and a 13x6.5 Propeller. the Power was enoth to Prophang and go vertical, but not extreme.
I have this plane ,would be a good candidate for a 25 - it could most likley use the power of a 35 to hover but weight will become a problem with the smaller plane Roger
hello, are you shure? by searching on the web, with a little help from google, i'm found this Picture ( www.link ) and it seems like it have a Fiberglass Tube to stick the Wuings together..
not showing a tube i still think its gluded its small enough to be like that ,i never saw a smaall plane like this with a tube. ((((spitfire)))))) was it bought from HK?
It has a Tube, i've got it at Home now! The Wings are sticked with the tube on to the fuse, and are locked from the inside over two screws. (at Photo 1 you can see it, if you know what you must looking for (and where),(its lokated neerely the yellow line, between the wihite and the blue part of the mainwing.) you can see it partly thru the "canopie window" (if you struggle your eyes *-) ). (its realy (to) hard to see..)
Hi. I see that CG is supposed to be 85mm behind the firewall? Mine is more like 90 . What can be the output if you have the CG to far back? My plane can twist sideways a bit if i give it full elevator up. Is that cause of wrong CG maybe?
thanks for all your help!
twisting has nothing to do with CG, with full elevator and slow speed plane tends to stall ( twisting before it dives either side). Move your batterie forward to achieve proper CG
I have a problem with the motor mount. Hard to believe but the point at which the motor is mounted/attached has been built, in the factory, upside down! Sure some will say no problem just mount it the other way up, but the thrust angles (down & left) are built in & turning the mount affects this angle effectively making it useless. Hobbyking require any items subject to warranty claims to be returned complete, but the shipping from NZ is equal to the cost of a new model so why would I send it back. Any suggestions apart from buying an aftermarket motor mount?
It's a bit of a hassle, but i would chop it into two, glue it back together and reinforce it with some plywood (as it is a bit weak and needs reinforcement anyways.
I actually did this on my own. I wanted to try out a Sk-42-50 engine, wich is to big to fit inside the eng mount. Therefore i chopped it into three sections (removing the middle section of 52 mm (engine length plus plywood thickness). Then i drilled holes and mounted the engine outside instead.
I ended up with a heavy but imensly powerful aircraft. I can use a small propeller with a 4s 4000 mah or 5s 4000 mah and get flight time around 10-12 minutes.
Great!
Thanks for your suggestions. The glue joints are not the best & so I was able to separate the parts & refit the motor mounting plate the right way up. Also I reinforced with epoxy & wood gussets etc. It's so much stronger & every thing is in the right place now!
Hello! I have not experienced in the field of electric models. I want to install the following equipment on this aircraft: TR 35-42D 1000kv Brushless Outrunner. Turnigy Super Brain 40A Brushless ESC. Turnigy 2200mAh 3S 20C Lipo Pack. Turnigy Electric Ultra-light wood prop 11x6,12x6. Is my choice correct?
Or try turnighy SK-35-48 engine.
Comes in 900 or 1100 kv.
Good prop for 900kv and 3 cell is 14x7 (power) or 13x7 (speed).
For the 1100 kv still on 3 cell, you can get smaller props. like 12x6 (power) and 11x8x3 blade (speed).
you may want to by a fome plane with he eveything in it and study how things are instaled and placed and how they work , and aftor you no how they work you will be able to build what ever plane you want to by just aplying what you no to your new plane it helps when there is a hobby shop close to you so you can pick up what ever you need but start of with the fome planes with everthing all ready in it and some epoxy so you can get use to the repars to the plane ..
The manual says 85 but it's more like 88-89. Get about 6 minutes in the air soi will be looking at diffrent props to see if icanimprove the flight time
Yes, you can fly it but you need to make a little bit of change, you have to purchase engine mount suitable to the aircraft. before going to attach mount with fiselage , you need to attach another piece of wood or metal cut in round shape (See Picture No:3)for the strength because engine produces more vibration than motor.Remove nose cone.
What are all the items we need to purchase? I know we need a motor, BESC, servos, propeller, batteries, radio TX and receiver. But how about prop extension shaft, extension servo cables and servo rods? If so, how long? And what else is needed?
You don't want a motor bigger than 35-xx I went with the turnigy 35-42c which works nice with a super simple 50a esc and a 3a besc as for the servos i used turnigy 1160a , three 15cm extension servo cables and you will need a 4mm prop shaft adapter. Also a 2200mah lipo 3s is about the bigger you want to go usless you want to cut some of the fire wall out
The turnigy 35-42c seems to come with a prop adaptor. Do I need another 4mm prop adapter? Or is this the same as a shaft extension? Also, Do servo rods come with the airplane? If not, then what do we buy?
Prop Ext shaft is required to put a distance with propeller & plane, if you need. extension servo cables if the servo cables are short in length then ext. cables are attached with servos, or if you need to place the receiver at a distance, you need to increase length of servo wire. For this model, for a good aerobatic flight, you will require a Turnigy 35-42D motor, 2200 mah Lipo-11.1 or larger and Spped controller(More than 40Amp)
I have changed my motor found to a front facing setup by cutting the motor mount down and fixed the 35/42 motor front facing added a 80amp speedy and powered it by 2200mh 14.2v li-Po's the increase in performance is excellent and it will pull vertical until you get bored. I would recommend anyone considering a 14.2v power setup to swap the motor round as the added cooling air prevents the motor burning out as mine did (before the mod) after just 2 minutes. The plane is very good for the money
mate, ive tried UH but i NEVER get an answer, particularly when you have already paid. Anyway i posted these over 6 weeks ago when new to this site so i have learnt my lesson now.......
I know the reason it came off??? That was not the question. The question was "do you stock spare canopy"? Which you failed to answer. I believe that the info you provided should be included in the instrucions, not AFTER it has ejected at 200ft. Scott
"if you get a spare".... Also, if you have a question to ask UH, it will get answered if you write to them, and not by posting it on a DISCUSSION board.
if you get a spare, cut out a piece of convering at the bottom at the back of the fuz, to let the air out, the reason it came off is because airs coming in but theres no were for it to get out
maybe your country is a frozen wasteland in winter, but mine is not, and seeing as its nearly summer here that doesnt help. Maybe you should try geting out from behind your computer desk, earning your 323 points and see what the sun looks like. hehehehe
Sun.... Buddy, I have been in the "sun" here in Baghdad for OVER 5.5 years now. I am SICK of the sun (and mortars,"happy fire", rockets, car bombs, road side bomb, bombs in dead aminals beside the roads, "friendly fire", "celibatory fire", EFP, IED, VBIED, the chow hall and having to get my groove-on in the porta-john)
IMHO Sorry Stowelsy but I think your going to have to fabricate a new one . Maybee you can engineer a proper mechanical locking mechanisme like HK aught to have in the first place. These magnets are a forlorn hope. HK do not have a monopoly on this misguided faith in magnetisme,
Pleasantly surprised by this model. It was shipped half way around the world and arrived in a couple of days in perfect condition thanks to double boxing. The specified weights are fairly accurate. The wingspan is actually 46 inches. A few things to be aware of: 1) Do not use any motor larger than 36 mm diameter (as the motor must be mounted inside the box). 2) Any battery larger than a 2100 mAh 3s Lipo will require minor modifications to motor box. 3) Use a small piece of clear tape to secure the canopy before each flight (mine blew off the first time!) 4) No hard points were built in the ailerons and the supplied screws for the aileron horns are not long enough - had to use my own hardware. Aside from those minor points this model is a winner. I wouldn't hesitate to buy another one. Awesome flight characteristics. Can be flown slow to a crawl or fast. Very smooth and accurate in all attitudes. Was less expensive than all other alternatives in the same class here in the states (even with EMS shipping added!). This one's a winner!

although this was supposed to be a budget plane i altered the fuse and fitted some carbon fibre landing gear, and du-bros rear. alterd the box to back mount a torque 2814/820 outrunner with the airboss 45a esc, and a 12x6 apc prop. its running on 4s li-poly too. i used the metal gear servos from hobby city as the fitted ok. the openings for the servos are actually mini size i think, which is ludicrous in my opinion, this plane should only need decend sub micro, anyway as for the kit, OK is the word i would use, if you are used to sebart or extreme flight and e-flite kits then the TM is a few rungs down the ladder from these. but for the money its a fairly good deal. the AUW is 44oz that with a large motor and 4s 2200mah li-poly. i did notice that the plane was fairly heavy from the start, the wings seemed heavy full stop. all in all i rather like it, but dont expect a sebart or extreme flight, coz its not! its a cheep nice looking plane, it needs some extra glue and another go round with the iron, and its a good one! hope ive helped someone with this review. cheers al pictures on this link www.link

Overall good product for the price. Nicely constructed and covered. The covering material is not the greatest though! The tail section of the fuse may need to be tweaked to get the rudder/elevator to be straight.
The kit ships with all the required hardware except a spinner.
Out the box the complete kit weighs ±710g
I suggest a flying weight of 980g~1120g
For a light setup use 9g servos*, ±85g outrunner and 1700 3S lipo
For a power setup use 16g servos, 110~140g outrunner and 2200 3S lipo
To turn a 13" prop you will need to replace the supplied aluminium landing gear with the taller 120mm HD carbon fibre version also available from UH.
*To fit 9g servos you will need to modify the servo cavities as they are sized to fit 30x12mm 16g servos

Very impressed. plane showed up very quickly with EMS shipping, and packaged very well, so no damage. The plane went together very well, and quickly with a few personal upgrades. I'm using a Scorpion 3014-18 and 45amp ESC, and flying with the Loong Max 2250mah 11.1v lipo. The servo holes fit HS-81 servos perfectly. Ready to fly, mine is 40 oz. It flies like a 30pcnt. Goes where you point it and very predictable. It's very stable for it's size. Trimming was honestly just a matter of a couple clicks of the elevator and ailerons. The ailerons are a little sensitive, but just put in a little expo, and it does some great rolls. I was a little worried about what I was getting since I haven't seen one of these planes before, and only a few reviews on here when I bought it, but I love it. This one is a keeper.
