Covering questions

I sure hope it turns out somewhat like I envisioned!

I finally got all the aileron hinges and rudder hinges removed. Now I need to get over to @ericrs and use some of his tools![emoji3] I need a good bit to drill the holes for the hinge hole plug. Then I'll plug them with a piece of dowel and drill them for a snug fit for the new hinges. What's the preferred adhesive for flying Robart hinge points in? I've got some gorilla glue I was thinking of using.

I wouldn't worry about plugging the holes with a dowel. Just re-drill them with the correct size drill for the hinges. You don't want a super tight fit because it will push out all the glue when you insert the hinge. If you have any holes that are really oversized, plug them with balsa before drilling. If you plug them with a hardwood dowel you'll have a hard time re-drilling them without the drill walking off to the side.

Mike you have tried the go 2 glue on hinge points???? I use it all the time on flat plate pinned hinges. Tried it on a hinge point and it pulled out but maybe I didn't use enough glue on it.

Yup. Used it on the last two planes I hinged. Robarts need lots of glue no matter the type. And you have to be careful not to push all the glue out when insert the hinge.

The last couple I hinged I used Loctite Go2 Glue. It has a nice pointy tip for filling the holes and plenty of working time. Before I used it I glued up a test hinge in a piece of balsa and there was no way in hell I could pull it apart without breaking the hinge or the balsa. So far so good. No failures yet.

Hey, that's some pretty cool stuff. Shock resistant means no vibrated loose hinges. Water resistant means tail dunkin' worries are over, and temperature resistant means when you're flying so fast that your tail feathers are on fire...it won't come loose! Oh wait, that's "fire resistant". LOL..... I may have to give this a shot next time. Thanks Mike for the input....

Lemme tell ya sumthin, mr neil westdorp put my 37.5 yak threw full throttle hell yesterday and i am definitely a firm believer in gorilla glue. My flat hinges are glued in with it and they are not pinned.lol

How close are you to gettysburg? We have an awesome field there on a private farm we have been flying at a couple times a month.

About 3 hours. Maybe less if it's on the east side of G'burg?

I've been dabbling with this thing when I get a chance in the evenings or over noon hour. I drilled all the hinge holes out and plugged them with a dowel. Then I marked the centerline carefully and drilled for new hinges. Now I'm sanding them down to match the bevel.

Some of the covering showed up today and I'm hoping the rest will be here by tomorrow.

I'm trying my luck out by starting with the side force generators.
