It doesn’t have AS3X. It’s small. It’s light. But, I’m planning on getting and reviewing it sometime soon. Are you going to buy it, or are you going to pass on this one?
I’ve included a poll, so vote in the poll and/or leave a comment!
Today I thought that I could give readers a preview of posts that I am going to post on umFlight in the near future.
Firstly, the Quads Invade umFlight post is a sticky, meaning that it’s always on the top of the page. To find my most recent posts, look at the recent posts area of my sidebar, or scroll down past the Quads Invade umFlight post.
Secondly, tomorrow I have a short post about E-Flite’s new Spacewalker. I also have a review of a NEW plane which will be arriving at my house on Monday. I might also be starting a series of posts as soon as I get around to it…
I haven’t been posting outside of the regular Sunday posts due to a slight lack of things to post about. But, things should be speeding up in a week or two as I get new planes to review and my brain gets unclogged from my recent frequent posting.
Oh, and I will be posting more pictures, thanks to a suggestion/comment left on my Quads Invade umFlight post.
Thanks for reading, and look for a new post tomorrow at 5:00 AM! I want to hear what things YOU would like me to post about, so leave a comment!
I know this is going to be one of my shortest posts. I also know this will be one of my most important posts.
I recently had a very close call with one of my Champs. Because my DX6 is broken and I didn’t feel like getting out my shiney new back-up DX6i, I simply got one of my many RTF package MLP4DSM’s which HH sells under Hobbyzone, Parkzone, and Blade brand names.
Firstly, I did not bother with a range check because I was going to stand in my driveway and fly the Champ up and down the street. Also, I completely forgot that the MLP4DSM is a low power transmitter like I mentioned in my review of the champ.
The DX6 which I usually fly with is a full power transmitter.
I usually fly my planes way down at the end of the street, with me still standing in my driveway controlling it, because there is an empty lot there.
Long story short, the plane was down over the lot, and the motor power cut out, and the Champ started spiraling down.
It crashed with a thud (I heard it). I was very lucky because it crashed into the bushes separating the empty lot from the house, but that doesn’t usually happen.
If I had done a range check, I would have seen the reduced range compared to my DX6 and not flown out as far. Additionally, if I would have remembered that the MLP4DSM is a low power transmitter, I would not have flown out as far.
The moral of the story here is to NEVER fly your first flight of the flying session without a range check. If you don’t, you may end up like me and find out that someone is wrong when it is too late.
As always, leave a comment if you have a personal story to share about how range checking can save your plane, or to discuss the post!
See you next Sunday!
I am now going to review the UMX Radian! I have heard that it is a GREAT ultra micro glider, but does it live up to the hype? Read on to find out!
In January of this year, I saw that a new product, the UMX Radian, was coming out. It even had AS3X! So, I decided that I would buy the UMX Radian at some point this year.
Well, I decided to get it in early August and I ordered it from Amazon.com..
Upon opening the box, I saw that it was as nicely packaged as the Champ was (see my review on the Champ here). The only flaw in my opinion was the way that you have to assemble it.
Assembly/ First Flight Preparation:
Assembly had a lot to be desired. The wing did not come attached to the body. So, I proceeded to try to screw the screws that attach the body to the wing into the holes in the airframe. I promptly lost one in the carpet. Then I lost another one. I ended up just taping the wing to the body.
Tip: do NOT attempt to put the screws into the plane over carpet. Also, cover the hole were the battery wire comes out while installing screws.
Other than that just plug the included USB charger into a USB port (I used my iPad/iPhone USB wall adapter), slide the included E-flite 150 mAH battery into he charger, and wait about 15 minutes for the first charge. 30 minutes for additional charges.
Hand launching was very easy. Just set the motor power to 25%-50% and give it a gentle toss. It will eagerly fly up to about 200 feet.
It turned tight, crisp turns and flew very nicely at an altitude of 10 feet and at 25%-50% throttle.
The gliding performance was superb (full disclosure: I have NEVER flown a glider other than his plane). I took it over my house, cut the throttle, and I was able to slope soar on the lift generated by the edge of the house!
The AS3X really helps in wind! I was easily and comfortably flying in 10+ MPH winds! 15 MPH was my limit. It felt like the wind was about to snap off at 15 MPH!
Belly landings on the grass were uneventful.
Recommended timer settings if using a Spektrum computerized transmitter:
Timer: 10 minutes
Any Other Spektrum Computerized Transmitter:
Timer: 10 minutes; start/stop at 10% throttle (one time)
Skill Level: Intermediate
Wingspan: 28.7 inches
Length: 16.5 inches
Flying Weight: 1.5 oz
Equipment I Used:
1. Thunder Power TP103CQ-ACDC Charger (link)
2. Spektrum DX6 DSMX Transmitter Only (link)
This is a great all around plane and glider, while with some assembly issues in the opinion of some flyers (including me), for a great price.
Thanks for reading! Check back next Sunday for a new post!
Earlier today, I was looking for a list on this. I could not find one, so I decide to make a list of UM AS3X planes. This list, for your convenience, also includes planes with SAFE.
I have posted before about what AS3X is. To sum it up, AS3X uses a 3 axis gyro to compensate for anything (wind) that takes the plane off of its course. This makes AS3X aircraft more resistant to wind.
SAFE is AS3X with an accelerometer (self leveling), flight modes, and a Panic Switch/Button. Read more about SAFE in my post about SAFE and AS3X.
Please note that this list only includes 1S planes (planes that use a 1S li-po batteries).
Also, Parkzone will not continue to make new ultra micro’s. All new Horizon Hobby ultra micro planes will be sold under the E-Flite brand.
The List of AS3X (UM) Planes:
E-Flite Carbon Cub SS EDIT: The E-Flite Carbon Cub SS is an AS3X plane, but it is not 1S. My mistake.
E-Flite UMX Radian
E-flite UMX F4U Corsair
Parkzone UM P-51D with AS3X
NEW (11-10-14): E-Flite UMX B-17
UM Planes with SAFE (and AS3X):
Hobbyzone Sport Cub S
Thanks for reading! Look for a new post this Sunday; Sunday’s only a few days away! I can only tell you that it’s a review on a great plane that is listed above!
AS3X (Artificial Stabilization 3 aXis) and SAFE (sensor assisted flight envelope) are two fairly recent Horizon Hobby innovations. But what are they? Read this post for an explanation!
Firstly, all planes equipped with SAFE also have AS3X.
AS3X is a 3 axis gyro system, meaning that if an outside force (like wind) knocks the plane off course, the gyros will compensate for this and put the plane back on course. But, if you move a the sticks of the radio, it will let the plane change to your new course. This system allows a RC plane to fly in heavier winds than without AS3X.
SAFE is the same thing as AS3X, but SAFE has an accelerometer, which brings in self leveling. SAFE also has flight modes and, sometimes, a Panic switch. A switch on your transmitter will activate Panic mode, which automatically brings your aircraft to level flight!
SAFE usually has 3 flight modes: beginner, intermediate, and advanced. Beginner mode has a limited bank angle and self leveling. Intermediate mode has a less limited banking angle and self leveling. Finally, Advanced mode has no bank angle limits and no self leveling.
You can progress through the modes, from beginner to expert, with just a flip of a switch or two (again, depends on the transmitter)!
And, with Panic mode, you don’t have to worry as much as usual about getting the plane into a bad attitude or it getting out of control; just press the Panic button/flip the Panic switch and the aircraft returns to level flight.
To learn more about SAFE and AS3X, visit these two web pages:
Thanks for reading! As a continuation of my AS3X posts, I will post a review on an AS3X plane and an AS3X mod in the next couple of Sundays.
Update: After flying the Sport Cub S, I have found that, on planes, there is only self leveling in Beginner mode. Quadcopters and helicopters have self leveling in Intermediate mode, but planes do not. Just keep this in mind.
If you are anything like me, it seems like the best (windless) days to fly are the days you can’t fly!
I’ve been sick for the past couple days and there has been ZERO wind. For the past two weeks, it has been 15+ mph winds in my area! It is aggravating, but, on a positive note, is giving me time to plot more plane purchases, more posts, and time to wait to fly my RC planes again!
Have you ever had an aggravating moment like this? Make a comment about it below!
