I do build a few of these to order but for local pick-up only (Napoleon, OH 43545). They are just too difficult to pack properly thus risky to ship.

Polaris/ North star


I built a north star many years ago. Beautiful , But it just wouldn't lift off. I tried many times, & many changes. Longer nose gear , more powerfull motor. 45 os. It would scream down the runway, But wouldn't lift off. I gave up after many times & adjustments,Nothing worked. Some one said a club he was in had several north Stars that Would not fly . It was set up acording to the plans (LADDY) Wrote ,It's still hanging in my garage for over 12 years,I am thinking of turning it into a speed boat. THE OLD GRUMP

It's VERY stable in ground effect. If you look thru the Polaris thread, you'll see several videos with guys driving the Polaris at high speed on the water like a boat. It does great like that, even with some waves. To a lesser extent, you can do the same thing on grass, too.

Polaris XL


Just finished my XL and setting the control surfaces. Problem with ailerons. In most of my planes I use two servos for the ailerons, can adjust each side as needed. Polaris has one servo to control both.
Right now they each have more down than up. Darned if I can figure out how to get them to give me the opposite.

Any change made on one side affects the other side. Sure feel kind of dumb right now. Been flying for over 40 years. Guess the old brain is tired.

Thanks for any brilliant ideas, or very simple solutions.

Can't you adjust the travel of that servo on the transmitter? I had a 7C for a while, and if I remember the travel of a servo in either direction was independently adjustable. I now use a Hitec tx and it has EPA, (end point adjustment), which allows travel both directions to be separately adjusted.

Quite right if I had a servo on each aileron. That would be no sweat,but this plane has the one servo controlling both sides. Any adjustments on one side affects the other side.

Thanks,

You're right Rich, got it. Next Polaris of any size I build will have two aileron servos, whether it's in the plans or not. I use aileron differential on most of my other planes, and it's easy to make precise adjustments; hard to do with just one servo. Sounds like you have some tweaking to do on the control rods, servo arms and/or control horns to get it right; good luck.

Are the plans for the Polaris available in CAD or CDR format perhaps?

This is just a really sharpe looking plane. I am planning to build one so I was just wondering about motor and esc. I'll head to the web site and have a look. Wondering about prices. My depron won't be here till next week so I have plenty of time before I need the motor and esc. Looking forward to the build.
