I have the Hanger nine Ultra Stick 40 and mine wont hold a sustained knife edge. I have just installed a stronger servo for the rudder and I'm installing some tape to seal my control surface gaps. I have a Magnum 52 FS on it for power. When I fly knife edge it hold's a nose up attitude but looses altitude rather quickly. Has anyone had theirs flying knife edge across the field? I really like the plane, its a bit heavy compared to the 60 size but it is really fun to fly with the split aileron setup they supply in the kit. I put more flights on this plane last summer than any other I have. I am probally going to do a few other things to it in the interest of saving a few ounces of weight. Thanks for your help, Jeff

It takes a lot of control surface mixing to get an US to even begin to do a nice knife edge.

Not if you use the sticks properly, it doesn't.

Are you suggesting that one should not use programmable mixing to fly knife edge with rudder only and instead to just use their "superior" flying skills and thumbs to make it knife edge??? WRONG!!! Do what you want, but when you go from an ultra stick, which will require tons of control coupling, to, say a precision pattern ship, which requires practically zero, you will be all goofed up. Not using programmable mix is for people who don't care how their maneuvers look from start to finish.

Maybe the CG could go back a little. My .60 size required a lot of rudder but the aft CG helped.

Bodyworks,
Thanks for saying exactly what I was thinking.

My ultrastick 40 will knife edge without using mixing but it is overpowered with a 91fx and I do have to work the sticks to do it. The cg is at the aft limit also.

I was thinking about the CG. It doesn't snap real well either. It starts out doing a barrel roll then actually breaks free and auto rotates like its supposed to. I imagine moving the cg aft a little should help that out as well. I had started working on my control mixing but then decided to make some other tuning style touches to the plane so I will have to start over with it this spring. Do you other guys that have these enjoy them as well. It is a fun little plane. I used the split flap system and that is fun having the air brake capability. It pretty much stops it right away when you pull back on the throttle stick.

I don't have a ultra stick but a sweet stick, and it doesn't do knife edge, it looses altitude quickly. It's not really designed for knife edge

I say using programmable mix is for people who don't want to improve their flying skills.
In my oppinion it should be forbidden in any pattern contest, it's cheeting. Sure the maneuver doesn't look so good, but that is the same for everybody. A real aerobatic plane doesn't have electronic mixing either

In a word, YES. I fly mine with a TT .46 PRO and can knife edge from one end of the field to the other. I could go further but I wouldn't be able to see it any more. I do not use any mixing on the radio as it's not a computer radio.

Also, I didn't have to add any weight to the tail to balance it, just moved my battery pack.

HEY GUYS...WHAT I HAVE FOUND WITH THE ULTRA SPORT IS #1 THEY NEED A GOOD RUN OF SPEED TO FLY ACCURATELY.SHE IS A GOOD ALL AROUND HANDELING AIRFRAME BUT REQS SPEED FOR THE KNIFE. #2 YOU MAY WILL HAVE TO MOVE YOUR C/G BACK SOME IF YOU ARE NOSE HEAVY.THIS CRAFT DOES NOT FLY ITS BEST NOSE HEAVY AT ALL.SHE IS NOT A TRAINER.BUT A RATHER AN STRONG INTERMEDIATE AIRFRAME.I HAVE THE US SIXTY.MY C/G IS APPROX 1/4 INCHE BEHIND THE SPAR.SHE REALLY DOES NOT NEED MASSIVE THROW OF ELEVATOR.TOO MUCH AND SHE WILL TUCK AND COUPLE ON YA.SO.... MOVE THE C/G OFF THE SPAR.PROP UP FOR SOME SPEED....ROLL NINETY AND APPLY (NOT BANG) THE RUDDER IN. I WOULD NOT BE TOO CRITICAL OF WIEGHT AS THE ACFT I VERY TOLERANT IN THIS AREA.INCIDENTLY MY ACFT WILL KNIFE EDGE ALL DAY LONG...EITHER SIDE AND I KNOW ITS A LITTLE HEAVY.DONT GET TOO CAUGHT UP IN THE MINOR STUFF.STRONG FUNDAMENTALS FIRST,THEN TWEAK THE SMALL STUFF.

Your message clearly states that the plane holds a knife edge with the nose up but readily loses altitude. Sounds like more power is needed to maintain altitude. Another reply stated that with a 2-stroke .46 he can hold altitude. Your 4-stroke .52 may not have what it takes. On the real stuff its pitch for speed and power for altitude, meaning that if you maintain a pitch attitude you must increase or decrease power to maintain altitude. Make sense? If you can keep the plane on edge and keep the nose up but are losing altitude, you need more power or thrust.

I have a Graupner 'Middle Stick'. Middle, meaning mid size. It's still a high wing. Anyway, plane was designed for a 40, I put a OS 46Fx on it. With a pull-pull, and max rudder throw, I can knife edge as far as I want. It couples just a little to the belly, and can be fixed with slight 'up elveator' pressure. CG is back pretty far, and it helps to have it running full speed, with a slight nose up attitude before rolling into knife edge.

HTH.

I have flown Ultra Stick 40's in KE with both the OS 46 FX & the TT 46 Pro. With those engines (or something similar) wearing a Tower muffler & an APC 11-5, power really isn't a problem. However, the plane hates it -- LOTS of yaw-roll coupling which makes simple KE flight rather attention-holding, & a KE loop is a real bear -- the best I could ever achieve with an Ultra Stick was a wobbly KE amoeba, rather than a loop.
