I have about a dozen flights on my new UMX Yak 54. What a blast. It took a while to figure out how to program the flight modes into my transmitter. I have to say all modes work as advertised, but with the advanced mode, which holds the plane in a hover or torque roll, I didn't feel like I was flying or getting any better at flying. So I fly solely in the standard mode now. And I've been able to hover this plane much longer than any other plane (I'm new to 3D). Otherwise it flies slow, has great response to the controls on high rates, and is really a blast to fly. I've not flown inside yet but will as soon as the weather turns colder - it does not need much room to fly. I've flown in some wind, and that was fun too - was able to just hang it up there, with the standard mode programming helping a lot. Wish the flight times were a bit longer (4 or 4.5 minutes), and the prop shaft is very thin (I fly over a grassy field so no problems landing, but don't nose in on a hard surface, even with this light weight plane), but especially for the $99 price it's really a fun plane to fly.

Glad to hear it flys so nice. I had the as3xtra a couple of years ago. It flew very nice. I didn't fly 3D with it - it actually was my first plane. Now I have access to an indoor facility during the winter and am learning 3D on a MXS-C so I think this would be a nice plane for indoor aerobatics/3D.
Thanks for the positive flight report! |

DX9 file
Does anyone have a model program file for the DX9? Just would make it easier to set up.

Hi guys!
Anyone have experience with both this plane (or the umx extra or umx as3xtra) and larger 3D foamie planes? The reason I ask is I have built a Twisted Hobbys MXS-C and am learning the basic 3D stuff. I can fly in an indoor soccer field during the winter, but haven't tried my MXS inside yet. Does this plane serve a purpose in addition to my MXS? Or will it collect dust as I grab my MXS instead? It seems to me that the Yak is so light & floaty (even more than my MXS) and just small enough that it might be better suited to continue my 3D education indoors compared to bringing my MXS indoors. I know it is way more fragile than the MXS. I did have the as3xtra, but only used it as a trainer years ago. By the time I was ready to try 3D it was so heavy from repairs that it hardly could fly on the wing! Thanks for anyone's thoughts. I'm trying to decide if I can really justify the $100.00 when I have a perfectly good MXS-C available. |

Hi everyone!
Received this for Christmas this week. Flew it today for the first time. Really nice plane! I had the old as3xtra, but used it as my 4 channel trainer, so no 3d with it. Question about the flight modes. I am using a dx6i, which has a 2 position ch 5 (gear) switch. In position 0, it should be in general flight mode. When I fly fast "on the wing" it acts like it is in a heading hold mode sometimes, and oscillates in level flight. I have read about this happening when in hover or torque roll assist. When I switch channel 5 to position 1, I should be in hover assist, but it flys normal and smooth! It's like channel 5 is reversed. I have not reversed channel 5 in my transmitter, though. Any thoughts? Thanks! |

2Winger,
The oscillation you are seeing is normal when flying faster in that mode (into the wind will amplify even more). It is a resonant frequency where the gyros are adjusting so fast that they over compensate in a rhythmic manner. You just need to fly slower horizontally or in a different mode where the gyro compensation is dampened more. It is quirky but happens with many different Horizon Hobby planes as well as other manufacturers. When you are hovering (air speed = 0)you shouldn't see any oscillation in that mode correct? |

I think the problem is that the programming is reversed for a 2 position switch. There was a lot of discussion about this in the as3xtra thread. It uses the same brick with the same programming. Position 0 and 1 are backwards of what the manual says. There was some discussion I found about this and the as3xtra on some HH videos.
The oscillations I am seeing are the ones cautioned about in the manual. I have 10+ Horizon umx planes with as3x. I have never seen the resonant frequency that you seem to be experiencing. My oscillations go away when I change the flight mode to position 1 (hover assist per the manual). This makes it confusing as that it is backwards from what the manual states. I guess I can either know the switch is backwards, or I can reverse channel 5 in my transmitter settings. I just don't understand why it is backwards from the manual?? Thanks for the help! It is a nice flying plane when it's not oscillating through the sky! |

I have had this plane for about a week now and am surprised it doesn't have a bigger following.
I have had multiple 4sites, original extra, and the as3xtra, along with a brushless converted as3xtra. In most cases, each airframe was an improvement on the previous in terms of flight performance (not necessarily durability). My brushless converted as3xtra was a great improvement on power and motor durability, however ate batteries like nothing else. My experience so far with the yak 54 is that it is an improvement on all previous airframes, including the brushless conversion. They have changed to a thicker foam which is considerably more rigid, this can be felt in flight where the controls feel much more crisp and direct. The power plant is different. I don't know if it uses a different motor or gearing but the note of the motor and the volume are much different to previous, the yak also easily hovers at 50% throttle which I have never experienced with any of its predecessors. I remember reading somewhere however I can't remember where, that the prop is also different. I believe it is a bit heavier than the as3xtra so I'm surprised to see the difference in power performance. Overall I'm impressed with this one so far. I know people want brushless over brushed but, having a brushless as3xtra, the yak is less fuss and out performs it. Sent from my X9009 using Tapatalk |

So many complain about brushed motors. For a light weight plane you can't beat a brushed motor for the performance. I don't mind replacing a motor every now and then. The brushless motors are great, but brushed still have a place in the hobby! |

I have just bought one of these! TBH, I am a Twisted Hobbys fanboy but the Clik and Crack Yak Superlite have been putting people off during our indoor fly ins by being big and loking like they might eat the Vapors (our venue is not very big). So, this Yak is almost as fragile and not too big so I hope it will mix it with them OK.
I have set it all up and just managed a minute or two in the garden before it got too dark to see. From what little I can tell, I can hover slowly round and hover so it should be perfect. I am happy reading dsp's comments above. Certainly, I had a couple of gentle impacts in the garden and it is 100% fine. |

Bought one of these Yaks from a club member and am wondering if these 220mah packs would be too much for it? Not real proficient at 3D yet, so am looking for 5 or so minutes of flight time just to cruise around at our indoor meets.
Thanks http://www.buddyrc.com/glacier-45c-2...ur-whoops.html |

Personally, I'd want something in the 150-180mAh range:
http://www.buddyrc.com/glacier-20c-160mah-1s.html Then again, the higher C rating might make the heavier lipo worth it. Of course, it doesn't sound like you'd be doing anything that would put a strain on the motor, so a lower rating wouldn't hurt you that much. Just a thought. |
