if you really want it to show up use broad black stripes. Red works well at close range and in good light, but in less favorable seeing conditions it becomes grey. I use 2" black packaging tape.

Glad to hear things went well with the second maiden.

It's been my observation that as distance increases everything turns grey. But as you suggest, with bold black & white stripes, circles, etc., the contrast is still visible. Some people color a plane bright red or yellow and think "boy, that will show up for miles", but on a cloudy day near the limits of your vision it's just two shades of grey, just a little darker than the white you probably started with. Color the top to look pretty and color the bottom for contrast, and make sure it's different from the top. Don't put blue stripes on top and black on the bottom, for instance, or you won't be able to tell them apart at a distance.

That was a tough build, but with the aid of the Construction Guide I was able to complete it.

I maidened it in the living room and it's still in one piece. Unfortunately, mine is monochrome (laser printer).

Now I have to try to find a color printer so I can produce four of them for the grandkids.

Thanks!!!

Re: Christmas Card Assembly Guide

I tried unsuccessfully to follow the direction "Attempt to fly across room." My wing loading is too high (and my power loading inadequate). I think I need a Gossamer Condor or maybe one of these:

Human-Powered Helicopters: Straight Up Difficult (5 min 36 sec)


See what happens at the end and think about repairing one of these machines. Depron is much easier!

Thanks, Tony! The kids LOVED it. Especially the reindeer in the windows. Flies really well, too!

Can you imagine building something that complex and fragile? I remember some of the early human-powered fixed wing machines built out of spruce and balsa, incredibly fragile and unable to get more than a couple of feet off the ground. Then along came MacCready and the Gossamer Condor, using CF and Kevlar to create a simple, adaptable, repairable structure, and suddenly it was possible or even easy.
http://en.wikipedia.org/wiki/Gossamer_Condor

It's like the Wright Brothers, who thought the whole thing through -- the airfoil, the structure, the control system, the engine, the piloting skill, the right location -- and suddenly it worked and was relatively easy (after all that brilliant and hard work). Maybe these guys with their helicopter will be able to do it too, but it all looks so excruciatingly difficult. And they don't have any control! I don't think the competition rules allow you to have an RC setup with the pilot on the ground.

Anyway, back to Polaris. I have two Ultras (one for a friend) sitting in a post office just across the St. Lawrence in New York state, a bit over an hour away. But I didn't get the arrival info till about 11:30 and the post office there closes at 12:30 on Saturdays. So it will have to wait till Monday. Ah well, the weather looks crappy next week anyway. So it may be Christmas week before I get to fly it.

My Ultra is scheduled for delivery on Wednesday. I may be able to squeeze in some building time before the kids and grandkids arrive for the Christmas celebrations. At least the "Runway" is ready -- 60 degrees and calm.

Kingsflyer,

Looks like a beautiful spot, I wish we had more spots like that here!

Just got these pictures this morning of an interesting Polaris built by Warren from Florida. Here is what the builder wrote:

" I just tested my newest design. It came about because my attempt to put am EDF on a Polaris failed (spectacularly) in an over-speed self-distuction. I had no idea that fan was so powerful.

So, I built my own design out of balsa, ply and carbon fiber. It spans 30" just like the Polaris and uses the same double-delta planform, but mine has a semi-semetrical airfoil. I also omitted the horizontal stab and elevators and went with elivons. It weighs 36 oz. ready to fly. It has a 64mm EDF with a 4000kv outrunner...60amp ESC and 4s 40c lipos.

It is FAST ....Unlimited verticle....... at least 3 rolls per sec. ....It is VERY FAST.....very stable for such a small plane..... Oh, and it is VERY,VERY FAST.!"

Looks FAST to me!!! Maybe the lower thrust line and the semi-semetrical airfoil allows the elevons to be more effective for takeoff rotation.
