Hobbyking Mini J3 Cub - Blue (PNF) (USA Warehouse)
The Hobbyking Mini Cub is a stunning plug-n-fly, EPO (super tough foam, easily repaired) model of an aviation icon (J3 Cub), and is ideal for beginners and experienced pilots looking for something that can be easily transported, handles well, is strong and assembles quickly.
Among the included scale features are an engine, pre-wired LED navigation lights and Cub style under-carriage. Full 4 channel control means superb flying qualities are guaranteed and a steerable tailwheel offers good manners on the ground, an important consideration, especially for beginners wanting to learn on a scale taildragger. The battery hatch is accessed from the under side to get you back in the air quickly.
This PNF version means all the work is done for you, a full colour instruction leaflet is included, the pre-fitted motor, ESC, prop and spinner are ready to go, the pre-fitted, pre-centred servos leave you with little more to do than glue on the tail-plane, set up on your reciever and go and fly!
Regardless of your ability, you will appreciate and enjoy the quality, ease of set up and superb flying qualities of the Hobbyking Mini J3.
It will work because you are supplying the same voltage but it will cause overheating of both your battery and motor. Lipo batteries should never be overheated for that reason alone I would recommend not using your 370mah especially since you can get the right batteries needed from here for under 10$usd hope this helps.

This plane is overweight and underpowered... Bad combination. I have several 3d planes and helicopters and do better than the average Joe with flying. I really discourage anyone from buying this plane, it is a waste of money! This plane does not fly like a CUB! I let an experienced friend fly this plane and as soon as he came off full throttle it stalled in a turn and did not have the power to recover. I don't think he ever had control of it. Final thought- nice to look at and maybe some of HK's other products fly, but this is a $60 POS....expensive lesson.
I bent the shaft on the motort that came with this plane. So I replaced it with a 16gm Hetronix 1700k that it said it came with, but it doesn' seem to have enough power. Can anyone tell what motor really comes with it?
Maybe you should buy a couple of cheap props with different pitch and size. A slow fly prop would increase performance a bit. Perhaps an 8x4 SF. If your in the US, it's worth checking headsuprcDOTcom
I am totally new to RC. I just bought this plane and a 6 channel HK60F controller w/ receiver. I am trying to install the receiver and I can't get any channel to affect the motor. What am I doing wrong? I have fresh batteries and can control everything else.
Well, could be a couple of simple things. One can be that you don't hav the ESC (AKA Throttle), or depending on the ESC, you have to 1st turn on the transmitter, then the receiver, and set ranges. First all the way down, ESC should beep, then (be careful here as the prop might spin), go to high again. You should hear some more beeps. After that, throttle should work normally. This all assumes that you've correctly bound the receiver to the transmitter. Good luck, and have fun!
Oops, my note above should say throttle in channel three of the receiver!

Let me start by saying I'm a novice, with experience limited to an HZ Champ, a 25" span home made foamy, and a Guanli Cub of about 30" span. I've attempted 2 flights with this Cub, and both resulted in disappointment and damage. My HK Cub weighs 9.49 oz. with a 600 mA battery and nose weight. It is a bit too heavy for my preferred style of flying.
The first time I had it out, I found that it's very sensitive on the ground; steering during take off was a problem. Related to this, the tires kept coming off the wheels during turns; the wheels aren't flanged on the outer sides, and though glued on, the tires didn't stay on for long. I re-glued the wheels and tried again. Also, it was tail-heavy out of the box, and required about .7 oz. of nose weight.
I'm rating value at only 3 because of its value to me, not its overall quality. I think a more experienced modeler would have the necessary skill to fly it fast enough to keep it in the air. In my opinion, this model is not novice-friendly. Otherwise, it's well made; all the parts fit nicely (except the clear plastic, which I had to cut to clear the aileron linkage). Generally, it's a nice package with a great price. For me though, it was an inappropriate purchase.

Didn't give it 4 crowns gave it 2. It's a POS airplane. LOTS of potential but unless you are willing to work on it don't think it's a reasonable value. The Turnigy 500 mah LIPO does NOT fit in the battery compartment without removing some of the compartment and the foam corners as where the wires bulge out of the lipo they take up another good 1/4 inch. I bought 2 of those and 2 Zippy 500 mah. The Zippys will fit with some pressure.
One of the solid strand (go figure) motor wires was broken on arrival. Fixed that. Asked what motor it was as I was going to replace the motor. HK could not tell me what motor it was. After the first nosed in flight the motor shaft is now bent. If they can't tell me what motor it is how can I get a new shaft. I guess I'll just have to take a WAG and get something. A previous review I placed didn't get posted as it was not much more favorable than this one. Waiting to see what will happen to this one.
IF...some of the details on the plane were attended to and if ALL the parts were listed somewhere, and IF you worked on it a significant amount of time, it could be a wonderful aileron equipped park flyer. as it comes, it isn't.

So far, this plane has not flowen yet. for being a plug and play, there is alot of ajustments needed. the elevator fin is not square at all with the wings. as well as in down position, it hits the rudder control horn allowing the elevator to become uneven, which in flight would roll your plane. some trimming to the plastic cover of cockpit is needed to allow better airlon movement. also, check your prop balance. i had to shave off quite abit to balance prop. even though its a plug and play, i think in the discripion there should be "Some assembly and minor ajustments will be needed before flight." As for that, its a cute little plane. i hope its durable enough for the wife to learn on(after test flight and controller rates ajusted) since she is a beginner.

The Quality overall is real good on the EPO that is. The 16gram motor is an awesome motor and although having a bit more than scale power is just not satisfying. I recommend NOT buying this PNF version GET the ARF model for 38 bucks,order TGY 1600A servos, Hextronix 24 gram motor, HK 8-10A ESC and use 2S 500mah batteries. Use 8x6 SF props. Toss the cowl aside (it's 7grams) and cut the rear of the bat compartment so the bat slides to the rear a bit. If your an inexperienced flyer cut the front of the bat compartment so you can shove the bat straight up into the cockpit to get a more forgiving CG for starters.
Nice little plane. Assembly time is ultra fast. The addition of the nave lights at this price point was a nice touch. The landing gear seems very stout and a steerable tail wheel was again a nice touch. Assembly of the tail feathers was simple. The instructions give an option of gluing or using a screw. No screw was supplied however I would never use a screw when I can use epoxy. Much better option in my opinion. The recommended 500 mAH battery was to large for the battery compartment. removing some foam from fuselage and removal of part of the back of the plastic compartment was necessary. The esc was loose fitting and floppy. Cutting a small piece of foam from the packing box allowed me to properly secure the esc. Hoping to teach my dad to solo with this little guy. Overall, nice plane with neat features at a good price point. Shipping from the USA warehouse was uberfast unlike waiting for stuff from their China warehouse. Keep adding inventory and I will keep ordering from HK's USA warehouse!
