I have retracts in my Ultrasport 60, and choose to go with som strong Robart air retracts with spring return. I wanted these heavy duty retracts to prevent bending of the struts, witch in turn will prevent the wheels to enter the wheel well. There is no problem with bending of the struts now, but the gear is so stiff that I am afraid that a rough or hard landing will tear the entire gear right out of the wing. It will not flex at all. The struts are 5mm music wire. I am wondering if I should downsize the struts to 4 mm, and somehow put a sleeve on the portion of the strut that enters the retract body so I can fasten the struts to the retracts? Does any one have any experience with this? Would it be possible to silver solder a sleeve on to the strut just to increase the diameter?

Rasmus

P.S Paladin, thank you for your inputs and ideas on the canopy

Make the spacer and put a hole in it for the set screw to pass through it and bit into the smaller strut. The spacer optimally should be made of steal but aluminum would be a close second. Brass would be my last choice because it is prone to fatigue cracking even if supported , if it is all you can get, plan to inspect it every fifty landings. The thing to avoid is a peace of spacer cracking from fatigue and working its way out. The missing peace will allow the strut to move causing damage to the remaining spacer and then the mechanism socket. My point being you can use anything just keep an eye on it for a while to make sure it will hold up.

I personally use aluminum from K&S to do this with no problems. Soldering would be difficult at best, and make replacement much more difficult than it need be.

Status: offline 		Hey Fellas, Here is some more Video of the US 1000, I had to break it up a bit, because the You tube site for some reason only takes 1 clip of say 5 if I spice them together, so all the clips are about 25 seconds to 1 minute each, I tried to cut the clips down and only use the parts where the plane was close to the camera so we didn't have to watch a dot in the sky at times, I'm still trying to master transferring from a MOV file to an AVI file without losing the quality of the picture. This link is to my youtube site, and the US 1000 take off.

Status: offline 		Hi All,

I have a big problem with my US1000. I was a gift from a friend, He build the plane so it 2mx2m for patern flying. I have a Siato 150 for power and every flight it a lot of work. It wants to snap every time I make a turn(Left and Right), when I roll the plane inverted I almost need 3D elevator throws to keep it from sinking. Were is the cg? Any thought and how to make it fly better or is this the way it should fly? Any help would be great.

Bob

Status: offline 		I had one of the guys maiden my Ultra Sport today. I am still not 100% confident after the cateract operation. 2 clicks of aileron and a click of rudder and it was hands off. Sure likes to climb at full throttle. She basically brought herself into the air at full throttle. The OS 55 really gives it great verticle and the retracts really do make a difference. She sure looks good doing a low pass with the retracts up. I need to upgrade the rods so they are a bit stiffer and I need to make sure the wheels are a bit straighter. Other than that she flys like a dream. Can't wait for this winter for the 60 kit to get started.

Status: offline 		N2yrd, I agree with Jrf, Check the balance 1st, I have mine around 5.5 now and she flys awesome,

The only other thing I can think of is maybe a control rod is hanging up somewhere, (Acting sluggish) On my US 40 I had a problem with the dual elevator rods sliding back and forth with ease, because 1 servo was pushing 2 rods, and they didn't like the tight bend at the end too much, which may have led to the failure of controlling the up and down motion, causing me to smash the plane in, and even in the US 1000 there is a lot of rod there to be pushing, what servos are you using?
