Don't have this plane but do have some experience with the motor.
I think you will ne dissapointed with this motor in this plane.
It will probably fly it around fine but won't be enough for hovering or serious aerobatic performance.
2cents...

I've had a lot of the UCD46 airplanes. One of my favorites. I love mine. I fly it with a Saito 82 which is an excellent engine for it. Many use a Saito 100. Some use a TH 75 two stroke or an OS91 2 stroke. The 46LA may get it off the ground. It will not hover with that engine or do ANY aerobatics. This is a 6lbs airplane or almost. You gotta get more engine.
Thanks

Ditto on what barry said, The LA 46 will get it in the air for simple flying, ( I had one on my
first plane, Avistar) but trying anything else will be out of the question, or very risky... I have used
the YS 63, S 82 & 100 on my two "Do"s.... They all worked great!!.. I think the YS 63/S 82
is perfect for it... Loads of power with the 100... Throttle control is a must...

I actually think its illegal in some states to fly a ucan do with the LA series of motors
.
You want at least a 90 or so 4 stroke or a 75 or so 2 stroke. As already seen in this post the Saito 82 is a popular fit. The tower 75 is a good fit for it too and probably cost about a third of the Saito.

we are talking about the ucan do 46 right. there are three different sizes. why would you waist 300 bucks on a plane that calls for a .65 sized 4 stroke.

Because the engine makes the plane when you are talking about 3d aerobatics. You asked a question, you can see the answer. Trust us, the UCD46 needs a minimum of Saito 82 to run or 75 2 stroke.Thanks

don't believe everything you read, especially when it comes to flying a 3d plane like a 3d plane. GP/Tower is going to tell you want the bottom line is to fly around in circles so they don't scare a general buyer away by saying it really needs a Supass 70 or .61FX for 3D action.
A 4stroke .65 would fly it - might hover, but not with a lot of pull out. Your 46la would fly it, and probably do loops and rolls and stuff, but the LA series 40 and 46 is notoriously weak, and don't swing big props that well - which is something that 3D planes need.
Plus as mentioned, the UCD 46 is arounf 6 lbs RTF, I wouldn't put less than a good strong bearing .61 2 stroker in it, or no less than a Saito .72 - the 82 would be a better fit.
to answer your other question "Why waste a $300 engine on this..." if that $300 engine makes my $120 arf fly like a dream, it's worth every penny. I'd rather spend good money on engines and radio gear than on a high-dollar arf - the planes tend to get thrown away a lot more regularly than the running gear. A good OS FX or Surpass series, Saito, or YS will stick with you much longer than the UCD probably will.

I recently purchased an SK 90 from http://www.kangkeusa.com/
I was pointed in this direction because i wanted more than the os 70 I had in my funtan x50 (about same weight as UCD, 6 pounds), and at a moderate price. I have not tested it yet but i have heard it is ported for lower rpms, thus being able to swing larger props, perfect for 3d. I think it likes to be proped under 10,000 on te ground wich means 15-16 inch props are in operating range. Plus, you can't beat that price.

I have a evolution .52 nx I might try tomorrow. because i flew it with the .46 la and it sucked. If that doesnt work. ill put the .52 in my decathlon and put the decathlon's .61 fx in it. if i thought i was going have to buy a large four stroke i would have bought the 60 sized arf. guess i should do my research before i buy

The .61FX will hover your UCD, guaranteed. I have a .65LA on a similar size fun fly plane and it has plenty of power. I wish I had the throttle response of a four-stroke but for a budget engine, the .65LA does very well.

If you put the 61fx in your 46, heres the cool thing - a saito 100 will drop right in with no changes to the motor mount - there's less than 1/16" difference in the prop hub location, and the motor mount bolts pretty much line right up. other than having to change your throttle linkage, and maybe needle valve hole in your cowl, running a 61FX is basically an easy way to step up to a 100 in the future.

Well,
i had an OS 46 LA on my Avistar and it was good.
BUT,
for a UCanDo 46 it's NOT.
I fly mine with an OS 91FX and i couldn't ask better.
Power?
Well,
that makes me laugh.
I take off at 2/3 of throttle and immediately i hover with less throttle.!
Rolls,
knife edges,
stall turns,
spins,
inverted flights,
cuban eight's,
walls etc are PERFECT!!!!!!!!!!!!!
Go with a bigger engine.
Go with a 91!

Well the evolution .52 was a good motor it will hover at just over half throttle with a 12x6 prop and has plenty climb out. I love this plane it fly's awesome. but I have some ****ty luck. after 2 days and around 20 flight s i had a flame out 10 feet of the ground while hovering and punished my plane! thanks for the input guys now im just waiting for a new fuselage. and its just my luck, its freakin backordered! shucks!
