I was flying the Oculus today... 80 degrees 10 mph, gust 12+. I had a crappy launch 250 ft or so. So bad with the breeze I was about ready to think about final aproach. Then in a minute it was about 700 ft. Less than 3 minutes I was at 1351 ft. This thermal was so strong and turbelent at the begining I was struggling to really have a smooth controlled glide path. At one point I had spoiler full open and it was still going up. I had the wing camera on it , really high. I have been higher with my paragon but the sky was not that clear so it was difficult to see well. This plane flies really well.

Target - thanks - that makes sense to me.

Just to make sure - we are talking about sanding 10 degrees into the 1/4" rib on the end of the left and right wing panels which attach to the center section before we glue in the plywood rib. We're NOT talking about the dihedral between the left and right wing panels and the small wings tips (that tip dihedral set up is clear).

Still don't see it in the manual though (scratch head).

After that, you will add the plywood caps to the tip root panels. The plywood is necessary for the incidence pins.

Yes, Tim. The 1/4" root ribs of the "tip main panel" needs to get beveled before the 1/16" plywood cap is glued on. This is on the tip panels where the wing joiners go in. Reference the plans sheet.

Making progress...


After months of not being able to build, it's nice to have the time now. This weekend I got the left and right wing panels roughed out. She's gonna be a beaut!

Fiberglass center wing panel


Fiberglass center wing per instructions - still a good idea even if only flying as an e-Oculus? Thoughts?

Thanks Clarence - I know you're quite familiar and proficient with the Oculus - so quite appreciative of your input - fiberglass it is :-)

Wing weight


Looks like my wing will be weighing in at about 28 oz before servos. Am I in the ballpark or shoutd I work at some judicious weight trimming? Thanks in advance.

Tim a light wing can be over rated, more than any thing you should concern yourself with is building it right and the weight shouldn't be an issue.

When I built Oculus # 2 I didn't weigh the wing so I can't tell you if you are heavy or light. So don't sweat the small stuff because the planform should handle the weight.

Tim-

I would wonder how you'd lighten the panel after its built, anyway!?

If anything, keep the tips of the wing light, and you will be better off. The center of the plane is a good place to have strength and weight in the airplane, IMO....

My Oculus coame in at 62-63oz with shear webs added to the main tip panels, and covered entirely in UltraKote Lite (no ParkLite used on my plane). The difference in weigt according to the website was very little, and I hate repairing covering, so a little more weight I figured was worth some puncture resistance.

I winched my Oculus with a busted wing and fuse at Sacramento to win the RES class.
Don't make your wing "light"....

R,
Target
