RE: northstar help

I don't know how that would stack up against other cloth and paint models but most "stock" jobs end up at the seven pound and a bit under under range IIRC. There's lots of wing area so it should be...

RE: northstar help

Right you are. Scaling for print is always a pain. In Photoshop and in the print function of XP the drawings show up very distorted. Apparently this is caused by a pixel aspect ratio correction,...

RE: northstar help

The last little clip in the video of the ocean stirred up was taken from my deck the previous week. After a storm our windows are covered in salt spray. We go through a gas barbecue every two to...

RE: northstar help

The pink one is a friend's. Mine is the white/teal green one shown in previous videos. He flew while I took the video. I noted the near dig in of the left wing tip. He may have been favouring left...

RE: northstar help

The pink Arrow flew again. Video here

This time it it has 2 or 2 1/2º of down thrust and the CG is 3/8" ahead of the most forward point of the range shown on the plan. It had one ounce of...

RE: northstar help

I take it you mean the trailing edge. I would try it at an inch or inch and a quarter ahead of that and see how you find it. With mine it took three ounces in the nose to move it to that range from...

RE: northstar help

Here's a video a friend shot of the maiden of version II. The camera was a non zooming pocket model so the video suffers but it does show how things went Video of Arrow II

This is the video...

RE: northstar help

The down thrust helps a lot on the take off run. Now I can ease it off the water instead of holding hard up elevator. The nose diving on relaxing the elevator is almost gone. Certainly it is no...

RE: northstar help

My first thought as well.

I have another one flying now with 3º down thrust and the CG as discussed in previous posts. Like you say, get it off the water "square" and after that Bob's your...

RE: northstar help

I found that the CG needed to moved ahead. Mine ended up a 1/2" behind the step and was working fine there until I lost it due to flutter. I started a replacement and will incorporate 3º of down...

RE: northstar help

It would be interesting to know if they have any effect on flight. Anybody got wind tunnel results? ;) I used them the first time but am wondering whether to do so in the second edition. Seems...

RE: northstar help

I had been enjoying some time away from work but now there are several projects coming all at once that I will soon have to start. Later today though I will print the plans and perhaps cut a few...

RE: northstar help

Good recovery on your part K.O. The stock balsa bottoms on the Northstar and Arrow won't take those bangs on the water will they? After the demolishing the Arrow I went and got the Northstar (Just...

RE: northstar help

Well yesterday didn't go all that well. ;) Near vertical dive at WOT; just about to pull out; big time flutter; no control; kapow! The clevis came off on one elevon and the hinge pulled out of the...

RE: northstar help

The trust and wing chord are 0-0 in mine which is how it is drawn in the magazine plan. It flies well like that but there are pitch issues during TO. I have redrawn it with 3º of down thrust in...

RE: northstar help

On the Northstar I used Goldberg hinge points. These are something like the Robart ones but are all plastic so there is no hinge pin to rust. They fit in a drilled hole in hinge blocks. The hinge...

RE: northstar help

The Northstar can handle the weight so as long as it flies well why worry about what the scale says. The first one I built about ten years ago weighed 7 ¾ pounds and was typical of what they were...

RE: northstar help

Repairs are finished and the CG as the plane now balances is ½" behind the step. For ballast I rolled up some sheet lead into a cylinder that weighed three ounces and drilled a transverse hole in...

RE: northstar help

Thanks guys. As erazz pointed out finding the right CG is critical. That first flight with a tail heavy airplane made for some pretty hairy work on the elevator. Talk about touchy! If you tried...

RE: northstar help

There is a slight alteration from the plan in that the wings are fixed. Spruce spars 1/8 x 1/4 (3mm x 6mm) spliced in the middle were used instead of the tubes which saved a little weight as an...
