@Wildthing - great to take these things in your stride - it's a learning curve after all!

Just foam and time, lately I just haven't had much time

 

[Wildthing]

Well with all the rain lately holding up jobs let's break out the foam and start a new Extreme. Spar was finished up today, now working on the wing and the other control surfaces that have to be sanded before folding.

 

[Timmy]

did you cut that out by hand?

I did

 

[Timmy]

I did

wow
good job then.
you must have a lot of time on you hands.

I have to talk myself into and sometimes that takes hours if not days

Don't worry you're not the only one going insane, I talk to myself too

All the surfaces are sanded to a taper. Wing is going together and it is a little bit of a pain because the airfoil is symmetrical so no flat side. All the other surfaces are folded and glued and aileron templates cutouts inplace just waiting on glue to cure. Ten cut them out and prep all the balsa for the hinges. The sanding to a taper does give you a nice smooth trailing edge and should be pretty aerodynamic, rudder is a good example.

That's some nice beveling action you got there
I used to do that on really small wings so I would still get an airfoil.
This used to be a small chuck glider for throwing in my living room but its tail broke off. You do a much better bevel though.

The only thing possibly different is I might have cut the wedge a little wider out of the fold, I also crush that edge down so the fold isn't as thick.

Thanks for those tips. I might remake that tiny glider with this new knowledge

Just try with some scrap pieces

 

[Wildthing]

Pieces are hinged and together, now onto the structure.

 

[Wildthing]

I been slow on posting updates, a little work each day but slowly moving forward.

Dry fitting the inner structure, it fits

 

[Wildthing]

Structure fit nice so now it is glued on and now adding the formers

 

[Wildthing]

Now dry fitting the rear skin, it fit pretty good but not perfect

 

[Wildthing]

Now to figure out where my control rods are going to run through after reconfiguring the tail feather to make a one piece elevator my normal route isn't going to work. Elevator servo is going to be mounted inside the fuse and the control rod will run straight back through the formers with no bends. Rudder will be a pull pull setup still but just routed a bit higher.

 

[Wildthing]

Now the rear skin can go on The rudder/elevator setup isn't glued in yet, just there to help keep everything in alignment.

Excellent work!!
