Flying Cat 90
Hi,
Not sure if this is the correct forum to place this - here goes.
I purchased the Flying Cat 90, and am now just starting to put it together. First off, most references in the manual speak of a 71 (not a 90), this manual has gone through some language to englsih conversion, I'm english and I can't understand the reference made in the section about mounting the engine. It mentions in step 1 about the molded lines in the firewall to be used for reference, mine has none. There is an "Attention please:" section that I have no idea what is trying to be said. I've built many planes in my day and have never run across this wording.
When I opened the box, there was a chip out of the right side just in front of the wing tip, also missing nuts for the bolts that hold the control horns in place. The location for the cutout that was to be used for the rudder servo was in the wrong place - out by about 4 inches lower than it should have been.
Now the worse part of this, with the plane sitting level upside down and the retract sitting in it's place, it is not perfectly straight up and down (perpendicular to the wing), and when viewed through the whole in the back you can see the formers are not aligned. Not sure if I'm being overly critical here, but I wonder what else is not aligned properly that would contribute to poor handling in the air. I have pictures of both and will try to upload them here.
Maybe I should have started putting this together before noticing the alignment issue, but since I'm located in Canada shipping back and forth is expensive, more than the cist of the plane.
Any comments would be freatly appreciated.
Kevin

RE: Flying Cat 90
Is this one of the first ARF's you put together?
The placement of the formers is not critical in a fiberglass fuse, as long as they do their job of re-inforcing the fuse.
Worry about the alignment of the rudder to the elevator, and the alignment of the rudder to the wings. These are critical.
Ideally you want everything perpendicular with only about 1/8" of variance or so, though planes will fly well with more than that.
You can sometimes heat a fiberglass fuse with a heat gun to bend anything back that might be slightly out of aligment.
The elevator and wings alignments are controlled by sanding the proper surfaces to get everything square.

RE: Flying Cat 90
Yes this is an ARF. My main concern is the amount of work I'm going to have to do to fix the retract positioning. Even the pre-drilled holes in the horizontal stab that mounts on top of the tail fin are offset from centre, as well as so far forward that if I use those holes the top of the rudder will hit the elevator and limit it's deflection. I'm of the opinion that there wasn't much care or QA taken when building this model[

Sent John a PM, so we'll see if anything comes of this. Not holding my breath, after talking to other members of our club it seems us "Canadians" don't get the greatest support from NitroPlanes and stay away from purchasing from them.
