no need to "pot" the wing saddle.

This is probably a to shallow "hole" for the wing "nut" coming out of the fuselage.

Check this and adjust it with a 1-2 mm deeper hole for the in the wing, but do not drill it (this larger diameter hole, than the wingbols) through the entire wing thickness.

OR this pre drill holes for the nut are to closely together (front and back). This can be corrected with making then oval...

got it?

Just finished my first 38g Spreadtow wing Polaris. AUW of 250g with a stiff wing will be good for me on those morning flights...

JE,
What fabric is the 38gr ST? Is it the Vlad ST? Does that have 2 or 3 layers of uni-carbon? That's nice and light. What dead air time can you get with that weight?

I have a light layup coming and am very excited. The Polaris will out float many planes even at 280gr! I can't wait to see what an ounce difference makes.

38 gr ST is Vlad ST. 2 layers of uni-carbon, at 30 or 45 degrees to each other. Tougher stuff to work with than the Samurai fabric but the weight is unbeatable. Unfortunately I delaminated a full carbon wing on my first attempt due to lack of resin Jonas is a master though I'm sure.

Maidened the glider this evening, got 2 hours of sticktime. Great launchheights, good handling. No comments about "hangtime"... . JB joined me and we had a blast riding the small thermals coming from the forest while the sun was setting.

Flying is fun!

Now all my gliders are ready for this seasons comps...

in text!
my placing:
The end of the peg shall be 30mm from TE.
The end of the peg shall be 12mm in from tip at that point
The front of the peg shall be 10-11 in from the tip.

Do this make sense?

NOTE!The drawing is from SIRIUS DLG and the placing as stated above works better for Polaris

Took the Polaris out today for the first time. WOW - It's a keeper! Floats like a butterfly and goes up in what I consider light lift. I made numerous low level saves that I would have usually passed on attempting. Don't know the weight or CG.

I didn't launch over 100' because I haven't reinforced the tip as I usually do, although it doesn't feel like it needs it. I was initially concerned about using an elevator spring; thus far it works great and has the same feel as a pushrod. Hopefully it will have the same feel when I give it full launches.

Hate I will not have it with me in Charlotte this weekend, I still have to finish the build (aileron covers, route antenna, cut excess wires) and play with the differential/throws. I do see why everyone loves their Polaris.

We have crap weather as well. I moved one forward 4mm from where I had it and left the other alone. I will see how that goes this weekend.

Just a couple more weeks!!!
