Looks good, Mark. I've never flown a Stobel. What is it about the Polaris that you like better?

Mike,

My Stobel's have been great airplanes and I have had good success with them but the Polaris to me seems to be just more efficient without sacrificing much at all in terms of performance.

Just the little bit of flying I was able to do today I seem to groove with the airplane very easily and didn't seem to miss the rudder all that much.

Beautiful bird you have there, Mark!

I've flown mine (same exact color scheme as yours) at 74mm and everywhere in between there and 66. It flies and thermals great with the aft CG, but rudderless turns are just a tad sloppier, and penetration coming home from downwind suffered quite a bit. I much prefer it at 68 for overall performance and ease of flying. I also like a little reverse differential in the ailerons. Basically very close to the MMT recommended settings.

69mm

i used to fly mine aft, around 72mm, but have brought it forward to within 65-69mm. it flies much better in the specified range and handles wind and turbulence better. you give up nothing in performance and it only makes the plane easier to fly. i still suggest you play with the CG, but i think you will probably bring it back forward. congrats on your new plane!

EDIT: i must have been typing when Mike was. i will echo everything he said.

Guys,

Thanks alot! I have to admit that I got this a week before the Nat's but do to work I was not able to get it together for the contest and so it lingered in the workshop until last week due to many other projects that needed to get done.

I am glad I got it finished now! I may try a more aft CG but like Mike said it may suffer in the turns due to no rudder. It flew really well at 69 and will probably keep it there.

Mark

I finished my Polaris today. Actually, it's not completely finished. Have to make an aileron wireing harness for it. I sole one from another plane. As you may recall this is the heavy layup version and she tips the scales at 10.2 oz. not bad. That's how much my beat up and repaired light layup Polaris weighs. I went rudderless with it. I'm just going to fly that way until it feels natural. If it gets too windy and I need a rudder. My Fr3aK will be flown instead.
I ended up with a CG at 67mm. That's right about where I was hoping to get it. Incidentally, I went and checked the CG on the used one I bought and its at 78mm. I thought it flew well back there. Makes me wonder if I could pull some nose weight out. I'm not going to do that however until I've flown it with the CG where it is now.

Now all I need is a break in the weather to go give it a maiden. Michigan winters..... mumble grumble...

Cheers,
Mike

Your post reminds me, I have a Stobel that needs some work for the spring.

Anyone have a stock Stobel throwing peg? PM me if you do.
I tried a wanted thread a while back and never heard a peep.

Thanks,

Pat MacKenzie

I though this was the "what did you do with your DLG today" thread

What a great flying airplane even without a rudder! I set mine up as per the Jonas setup sheet and she flies great. It is a medium layup with the molded in servos and am using a MKS 65 for the elevator with pushrod. With the Craig Robinson seagull peg it came out to 9.8oz balanced at 69mm. It felt like I could move the cg back a little more, will have to try that later. What it the farthest aft cg anybody is using for the Polaris?

Looks like I am going to have to order another one and sell my Stobel's!





The receiver and 2 cell lipo are in the nose with the PLD regulator just in between the servo. I am using Airtronics and was able to put one antenna behind the servo on the floor and the other one taped to the hatch. No range issues what so ever!

Sell your Stobels?!? May I ask which Stobels you have, and why you like the polaris so much more?

I have a Stobel V3 and was just going to start researching my next plane, but I wanted something of equal caliber but..... Different if that makes any sense.

Fellow polaris D's,
I am in need of one (1) regulator. If you got one, and want to sell it, send me a pm. I dont always use a regultor, but when I do, I prefer PLD.

If you can't find one use a LiFe 500 mah from A-main hobbies. 6.6 no regulator needed

I flew the new Polaris today. It sure is a nice plane. I really like the way the day glow green shows up against the black of the CF. I also like that way it simply leaps out of the hand when I launch it. I still have a lot of trimming to get sorted out. This plane definitely flys differently than Polaris #1. That's to be expected with a CG that is so much different than the other.

I still think I need a rudder. I just don't think I can get use to steering it down low and between people with out it.

Also, I have the pre installed servos. They are those damned Hyperion 09s. One of them double centers slightly and it some times causes my launch to veer off a little to one side. I can't for the life of me understand how these became the gold standard in the DLG world. I've now owned six of them and have a 50% failure rate. If I cant get it sorted out I'm going to have to replace it and I'm dreading that. I'm betting they are really glued in there.

Do it rudders are great! Flew my Espada RL today and loved the rudder just not on the Polaris. Good Luck...
