Hi:-)
I have a brand new os.91 surpass 4stroke.
What plane suits that engine, I want to hover, ke and the rest of the stuff!
u cando 46? or the 60 size I don"t know!
3d is new to me, just have 1 3d plane, that is underpowered.

Thanx

The weight of the 91 surpass is just a perfect match more the funtana x50 which needs the extra weight to balance.

I have a Saito 1.00 on my U-Can-Do .46 [>:] I added a bit of weight to the tail, and it flys like it's on rails. I think your .91 will do better on the .46.

wow! saito 100 in a 40 size plane! How will it hover with the 91? hover is very important to me, as you might understand!

Well, my UCD hovers at a little more than half throttle, I think your .91 will hover it pretty good at about 1/2-3/4 throttle. I bought it w/ the 1.00 in it. It's a fun plane!!! Here is a pic of it next to my Stinger .40. You never would have known I had a Stinger .40, would you?

Maybe
Kyosho Flip 3D
Fliton Inspire 60
GP Reactor
That is sort of an in between size engine.
Its not really enough power for a plane the size of a 60 size U CAN DO, Mayhem, Showtime etc,,, if you want really good vertical pullout. But its almost too big (due to weight) for the smaller planes because of its weight. I know of some guys that are flying 2 stroke that weigh about the same thing on the Fliton Inspire. They should have some flight reports on those threads eventually, keep an eye out for them and see how it flies with a 24oz engine.

omg, what the hell are you powering your planes with??
That stinger looks like a f3a patternship, becouse of that engine!
But if you should recomend a 3d plane, what would it be?
I want the ucd 60 size but I dont know wich engine to go with, you probably would have installed a saito 220??
Of course I"ll by a new engine if the plane demands it!

If pullout from hover is as important to you as hover is - the UCD 60 is not an ideal match for the .91. The 91 will fly it and do most things but it would be the minimum power to 3d it. I started with a Saito 1.00 in my UCD60 then upgraded it to a Saito 1.25 and 16x4W prop which is almost a perfect combination (a YS 1.10 would be that).

If you are serious about 3d - ignore any prejudices you may or may not have and consider a profile - the MoJo 60 is an excellent match for the 91 as are a number of other profiles such as the OMP ones. These are seriously good 3d planes and, talking from experience, the MoJo is about the strongest plane I have ever had - very important when learning to 3d.

Otherwise the Funtana X-50 or the UCD 46 as mentioned earler are both good matches.

Thanx for good advice, everybody!
I just ordered a ucd 46, so I will se how good the combination will be.
What about servos.. will my 3001 do the job? also, I have a 9254 that I think I"ll use for the rudder.

Murdoc....

Good choice on the airplane and engine. You'll love that combo. I fly mine with a Saito 82 and it's excellent.

I don't think you'll like the 3001 servos. Go with HS645 minimum. The control surfaces on this plane are huge. It is prone to flutter if you don't have a strong enough servo. Also, Don't FLY it Fast. Fly it slow. I wouldn't use the CA hinges that come with the plane. Use Radio South CA hinges or go with pinned hinges. Many also strenghten the landing gear. On my latest one I haven't. I just land it smooth. But it is a weak area. Also, you'll want to use carbon fiber pushrods or 4/40 pushrods to stiffen things up a bit.

This is about the most fun airplane I have. It is a riot to fly and is one of only a very VERY few airplanes that will do a rising inverted flat spin. I'd set the CG at 5 1/2" to start. Still very easy to fly and land there yet is better for 3D. This plane hovers about as easy as anything on the market. Great plane.

Thanks
Barry

Sounds good man!
I"m so exited about this plane. I read some of the ucd building thread and my impression is that everyone is happy with this airplane.
One of the few 3d toys that looks good
What about 9254 on rudder? Used it on the tail in my raptor 50. and s3305 on the rest?

hi Murdoc

i have a Weston Hype 3D with Surpass 90 up front.
it does all 3D stuff very well except snap rolls which are a bit stodgy.
it will do climbing flat spins upright or inverted
it K/Es with little coupling and K/E loops with ease, you could do a lot worse

regards piroflip

Nah, a 220 isn't enough power. I'd jump up to a DA-50.

who would have guessed??

I had a OS 91 (apc 15x6) and a Satio 82 (apc 14x4w) on my UCD 46 and thought they were both a good combo it.... i had to put the battery as far back as possible with the OS91 to get it to balance

I wouldn't bother with expensive servos unless you already have them.... i used JR 537's on mine and never had any problems, like Barry said, i would use 4-40 rods on the elevator and rudder and beef up the landing gear too.... one last thing, if you put the wheel pants on and your LG does fail, the wheel pants will poke a hole in the bottom of your wing on both sides

About the wheelpants, that happend on a rough landing wit my tojeiro 50... scary problem. The wing can actually get serious damage by the wheelpants!
How did your ucd hover with the os 91surpass?

It'll hover fine, man.

maybe a funtana x50. IMO it needs the extra nose weight. I have got a sk 90 2 stroker (ported for 15-16 inch props) wieghing about 23 ounces with pitts. Plane balances perfectly with the engine. Battery is just behind CG. Plane comes in just under 6.5 pounds. I have got Hitec 475's all arounds.

the OS 91 hovers the UCD 46 with no problems, that engine is more than what you want it to do but if you have one then you might as well use it on the UCD

Thanx for good answers.
I will pick up my ucd tomorrow the funtana x50 is also a nice plane, but wouldn"t a 91 4stroke be to much?

strive for a setup weighing abour 6lbs and about 800-1000 squares
the name of the model means little -the weight means a LOT
after 7 lbs you are on the wrong side for really good 3D stuff with that engine

So you mean the x50 is to heavy for good 3d?
I"ve read some threads about it and people don"t seem to happy with it!

I agree with those numbers... Anything outside of those parameters is gonna take a lot of work to 3d....

You guys need to try some profiles.... These fatty birds mentioned here don't 3d half as good as a profile... Once you've flow a profile in this size range, you'll throw rocks at those other birds

Well written by the instigator of the best 3d plane I have ever owned.

I used to thoroughly dislike profiles - until I tried one. They sure do beat the others hands down when it comes to true 3d. Even people at my home club who absolutely hated profiles until they had a fly of my MoJo 60 are converted.

I have tried profiles (Fusion 90 size with YS 110) I can't tell it is any different from my UCD with the same engine. It probably does a better knife edge but that's it. I think the UCD does a better waterfall and flat spins are clearly better. I like the profile don't get me wrong...but to make a statement that the UCD or other nice 3D plane doesn't fly "half" as good is a blatant lie. I get real tired of hearing you profile guys putting everybody else down. My UCD weighs 7lbs 12 ozs. My Fusion weighs 7lbs 8 ozs so there isn't even much difference in weight. Anyways, give the regular guys a break. Don't always slam everybody and insist they get a profile.

I think my Velox 90 size by MaxAir will fly better in everyway than my profile. But it doesn't fly twice as good.

I did notice that you own the company that sells the MOJO and other profiles. Maybe that has clouded your thinking.

Anyways, I have nothing against profiles. They fly nice. But they certainly are not Twice as good. Not even close.

Thanks
Barry
