RE: Ultrasport 1000 engine advice
A7bldr et al:
Believe it or not that was only my second RC project! what was I thinking?.... Yes the covering took many hours, I used metallic Monokote and chrome trim tape-5 colors in all. I even clear coted it to seal the edges.. I have come to prefer fabric and will probably use Solartex on my recover some day. In hindsite, this plane was as much about learning the building skills, tools etc as it was about the flying results.
So many planes go together straight and big. Done again, I would probably go with something prefabed but "YES" this plane was very much worth it and here's why:
Building is more than half the satisfaction of this hobby for me and this is very much a builder's kit. I build more than my share of ARFs but these days when people see and ask about the US1000 and hear its a kit build they often drop their jaw and say: "people still do that"? Its impressive on the flightline. I arrived a few times with a US 60 as well...that was cool.
I have 13 years with this project, hey, a Sonex or Sorarai or whatever won't be such a big jump, right.? Okok there's the costs difference....
Another reason: For all of us there's that one experience we have where we see a pilot or a plane and say- "that's me someday". For me it was Mr. Chuck Grinrod and his YS powered pattern planes practicing at our local club MARCS field. I was mesmerized by the sound of a quiet pipe and the grunt power of his YS's. Monday I flew the US with a 90 degree cross wind- nobody else
Now the US 1000 is on Hyde Out or whatever the current latest mostest is in pattern, but this plane has a solid smooth character and look in the air that's very distinct. I get goose pimply when I decend from a stall turn and it makes that giant scalle "whoooosh" sound. Other planes do that ofcourse but there's a lot of curves and carves on a US that make it an unlikely choice for construction en masse. I'm sure I'll be proved wrong on that one- the Chinese products are amazing to me.
Also, this is a plane that has taken some growth on my part to master and not too many of my projects have stretched me to improve as a pilot/builder like this one. (hHe others would be the IFO, Zagi and Shockys).
In the air this plane conserves energy well, and glides are long..landing attempts at high idle with a less than dialed in engine - well just didn't happen. I learned to raise the angle of attack with elevator for air braking, I added glow ignition giving me the confidence to run at very low rpm on final. Seems some added flap action would help the landing performance, perhaps a split aileron with a larger inboard section that function in 4 surface mode for aileron?
A couple other thoughts...Mac flex pipe should be backed off 1/4 turn when attached with RTV or silcone, that way it will have someplace to go if it needs to,-Otherwise breaks in the flex at the header will be a very common occurance on a soft mounted YS.
RC, thanks for chiming in. It looks like you put in a lot of effort, but it was worth it!
The cover job alone must've taken days...
