Uncas,
Yes it is higher than the other engines, but it's worth every red cent of it. Man you can not go wrong with this combination.

There are real good deals on super powerful engines. My favourites are the ASP .52 "super series" and the new Tiger Shark .56 I only got the TS .56 recently but like it a lot. The same weight as a .46 but almost .60 power. I think it comes from the same factory as the JEN .56. Handles a H9 Twist 3D with power to spare, and the transition on this engine is pure silk. Kangke USA sells them for $ 89.77. I have a few ASP .52 engines and have quite a bit of experience with them. The are sold by Goldscallop.com for approx $97 .Made in the same factory as Magnum, this is the cheaper brother of the Magnum XLS .52. These engines are VERY powerful, and once they are tuned right they are very reliable. You don't have to spend a fortune for great 2-stroke power.

K&B 61 is $80, recommended props a 13x6, might swing a 14x4

You guys consider $180 buck a fortune for a RELIABLE, CONSISTENT, AND DEPENDABLE engine?[X(] We are talking about a proven engine and reputable company; we are also talking about a 3D aircraft. Sure, go ahead, buy some of those mentioned above, and watch just how much of a fortune you spend to replace and repair your 3D aircraft. Oh, by the way the engine is extremely important when you are trying to hang an aircraft on its prop 3 feet above the ground. Watch what happens when your inexpensive engine dies on you in a torque roll. If you are going to take the 3D plunge, be smart and realize that just because something cost a little more than others does not mean it is over priced. Research and Development cost money! By the way, do not add unnecessary weight to your 3D aircraft. A .91 two stroke [:@] is WAY too much power and weight for this aircraft.

theres always the one a 91 tow stroke in not to much f'en power or weight get freaken real dude OK use a webra 50 OK cg is a 8 inches back OK add 9 or 10 ounce of lead OK holy freaking wow that webra 50 weights the same as a 91 fx you screw up and try to blast your way out opps you hit ground game over with a 91 fx boom your outa there still looking like new no extra weight for repairs win win

A .91 size engine on a .46 size airplane? A .46 3D airplane at that. (Smart) NOT!

Go for it! Have a ball! I'm the real idiot here You fly yours the way you fly it, I'll use a little logic and common sense and fly mine the way I fly.[X(]

sounds good man i'll fly mine with a saito 100 i don't use two strokes for 3d my fx's turn 10,200 on apc 15/6 my saito turns 10,100 on apc 15/6 why use a lite engine and add lead mnfs?????????? call dave brown i'm bolting a 91 fx on my sport cap 232 to it calls for a 58 woo wooo wooooooooooooooo i guise some people drag out of a hover some people pull out of a hover some people punch out of a hover i just like the oooooooohhhhhhhhs when a 5 or 6 pound planes punchs out with a saito 100 on board [8D] [sm=punching.gif]

A10hog.

Tower has the .50 sx/h at $210 not $180. Maybe they are cheaper elsewhere. This is more than 2x the cost of other engines and not insignificant for me. However you are probably right, this is an extreme application and may require the lightest most powerful engine. I have never regretted buying good stuff.

So the problem is not really which engine but how to sneak this past the wife, hehe.

There are two diffrent versions of the OS .50 SXH. One is the Hyper it cost $208 the standard cost $180. I have the standard version with ZERO Ballast to get the C.G. at 5 3/4" back. The airplane weighs 5 lb 14 oz. Vertical pull is awesome. The engine is very reliable and if you would like to have a 3-d contest with what ever you can come up with Bring IT. This setup will kick the crap out of any other overpowered over wing loaded airplane. These threads are something else. A person ask what engine to run and then they get an answer that doesn't suit what the person wants to here. Why ask if you have allready made up your mind to run a Chinese engine that will cost you your airplane. Or it may not cost you the plane but you will never hover below 100 feet due to the fact your engine may die at any time. I know I'm making a lot of people mad but there is a reason OS has been in business so long. So go buy a U-can-do .46 put that brick on the nose/ Blubird servos in the tail and run the cheapest fuel you can find. Let us know how it turns out. Oh I forgot 1500 Mah 6 volt Nicad in the rear to balance it out to 8 lbs. Great plan. Let me know where the fly off will be. I cover most of the country in one year. I'm sure we can arrange something.

haw if you could get it out of the over weighted over powered planes prop wash. dude a os 50 never kicked nothing on a u can do if it did I'd be running one I'm running a saito 100 .a os 50 is ok a a profile no its not over powered any way the u can't do 3d wing loading is what to low mine will harrier without spoilers now

Uncas You are looking at the wrong engine. Now don’t get me wrong the Hype version might be even more powerful but I was referring to the standard SX-H version. I just flew mine today with the new engine. The engine started on the very first flip ever, and ran like a champ all day. The vertical is unbelievable. You can get the CG right without adding weight. Man trust me on this one, YOU CANNOT GO WRONG WITH THIS APPLICATION. Wing loading is very important with this type of aircraft.

Hey now as for the wife, [X(] dude you are on your own there... I have enough trouble with mine. But hey remember its easier to say I'm sorry than to be told NO...

This thread is about a U-Can-Do .46, not a cap or a profile. I'm not sure what you are talking about now.

yea i know its a u can't do 3d maybe mine is built very tail heavy but it takes a saito 100 to get the cg at 6 back from the leading edge oh the sport cap is another plane I'm working on you said a 91 on a 46 plane i did it again engine mounted cg perfect only thing i know is mine is tail heavy with a saito 91 cg great with a 100 8411's every were but throttle 810 g there

A10hog,

Thanks, I did not notice there was a hyped engine.

I noticed the specs do not show much difference between the sx and the sx-h. (1.80 bhp)

So what type of fuel are you using? Are you running at 30% Nitro? That is the only real difference I see betweeen the two, and maybe that is why it needs the large head for cooling.

I cannot debate you on the subject of a four-stroke engine. I know nothing about them, but what I do know is the .50SX-H is the way to go for the U-Can-Do .46…

No I'm using 15% Nitro. The carb is larger, and I believe the porting is different. But one thing for sure it makes a Heck of a difference.

nope the hyper is same bottom end head and carb only changes check the stock numbers same to run a os 50 efficiency you need to turn 15,500 rpm you do know your warranty is voided don't you improper usage of engine

I'm the least worried about a warranty. The specs does read the same, but I'm here to tell you that the two engines do not compare. The best I can tell you after looking at the specs is that the carb makes the difference. We need to ask that question to the O.S. rep here online.

Hey: Prop Hanger

Just two questions, what airplanes have you flown, and how long have you been in this hobby?

Bob

Ive been flying for 15 years I've flown I'll just list the 3d planes

fun one

yard dart

both u can do's ys 110 saito 100

120 ultra sticks saito 180 will have 2.20 when there here

hangar 9 sukhoi da 100 got power

gp patty wagstaff da 50

omp 540

kantana arf

extreme flight edge 540

tt fun tiger

gp giles

magic 3d

magic extra

goldberg extreme 330

goldberg 540

about 4 other profiles

cap x

a few more true 3d planes i also fly pylon and scale

believe me i know how to fly 3d i under stand the concepts behind it i have been prophanging since 89 or 90 how i got called that i learned to fly when i was 5 been flying ever since

i know i sound like a fussy old coot but I'm 20 years old just like people to understand the best setup for that plane i have a box of just used engine mounts were i tried the recommend engines and had to change

So, you've been flying 3-D almost as long as the guy that started it all, I find that very interesting. I also noticed that you have only listed aircraft that date back a couple of years, again, interesting. Personally, I don't believe you posses the knowledge base or expertise, to be giving much advice on the best setups for anything just yet. Maybe in a few more years, if you keep your mind and ears open. Just my opinion.

[:-][:-][:-][:-][X(][X(][X(][X(][X(][X(]

I"m in agreement with Jason and Bob on this one, here's the scenario I have, but only its not the UCando its on a phoenix Funstar which comes in way lighter then the ucando 40. My funstar with a 46FX weighs in at 4.6 pounds which is not a bad match so when you put that small of an engine in comparrison to the 46FX on a 6+ pound plane well lets just say your going to be limited.


Now on my OMP yak and my 60 size Ucando which both come in at 7.6 pounds equally matched with engines, I've found the Saito 100 and the 91FX to be a perfect match. Yak- Saito 100 Cline regulated and Ucando 60 - 91FX perry pumped.

Blackie

OK lets see the great planes fun one was discontinued in the early 90's so was the yard dart people were hanging planes on the prop before we had the Internet at the level today so there no way to really prove who invented flying 3d the best way to settle this ni I'm not th best and no i can't give the best advice but I'm sure better than you at flying 3d or posting so let it go this is a long thread you don't want to see it get deleted you mite loose 2 posts remember theres always going to be somebody better than us i watched a kid flying a plane on the pb site he would laugh at most of the toc guys[X(][>:]

Blackie,
Its good to see you chime in on this subject. We are just trying to get this guy to see that his combination of power plant to airframe is WAY off the hook. Bob, Jason and I all have this setup and have gone through the engines to get the correct setup. The setup you are using is perfect for the .60 size U-Can-Do, prpophanger would most likely put a OS 1.60 on his so he could quote "blast out of there".

Hey its good to hear from you Blackie, come on down to SA and fly with us sometime.
