Looks spot on!

My sally at 166g flies really good in light winds, it can get it nose down and carve around or float around! Was in sub 10mph wind with the wind being off and both steves and mine were lapping it up!

I'll get there!!
Zally 1 has a broken off nose pod...
I think I'll trim it and stick it upfront with a bagged tail and light wing..
Just to see...
But, I still don't know how you got to that weight????

Sean's is up next if I can just get her done!!!
And he's fussy!

Hmmm.... quiet but not forgotten, eh?

THIS WEEK: bagged my first wing. Just 1/2 a Sally wing, but a wing, nonetheless.

Life's a learning experience: what I learned this week about bagging wings:

1. Some guys will GIVE you mylar, just because they're nice and the're glad to have someone else join the "brotherhood of composites". Wow

2. Sometimes the simpler the better -- I tried all kinds of glue to make my vacuum bag, and in the end had a leak and lost vacuum after about an hour (hence the open end of the LE). The system I borrowed didn't have a pressure switch, but did have a good vacuum tank. It depended on a "no leak" bag. I knew that I had a leak somewhere but couldn't find it, so sometime between 1:30 AM and 8:00, lost pressure. The next bag, instead of glue, will use poster putty to seal and will work great.

3. Spray painting mylar is fun and easy and looks like you know what you're doing.

4. Fiberglass should be put on the wing on the bias, or it allows for lots of twist.

5. Don't write "good side" with marker on the mylar before waxing -- it comes off to adorn the fantastic paint job, even though it's on the back side of the wax. And then, don't use acetone to try to remove the words.

6. Don't use too thick a vinyl for the bag.

7. Make a bag that opens fully and then is resealable -- it makes it easier than trying to slide a wing in a long, narrow bag.

6. 1/2 wing weight of 53g should make a reasonable full wing, but a fully loaded pod of 135g might need some lightening, given the hills here. That will have to come after final construction.

Full wing bag this weekend (if I have enough FG to cut a bias wing). Stay tuned!

Well done Dave!
I think your finish looks great!
Pity about the loss of vac.
Same happened to me, except it was the pump!

Don't pay my prompting any attention!

Not one, but two!

That's not a bad weight at all Dave!
My one wing core weighs 33g
sooo ...
10g cloth and +-10g epoxy....
Very light!!
What was your glass lay-up??
Did you lay it up on the bias? and does it "feel strong enough?
Good one Dave!

I'm guessing on Dave's behalf...
He may have used some lighter foam.

Come Dave..
