Today I look around my shop for something to do. So I cleaned the ink pens and then found nothing. So I dug through my scraps and looked at the good wood I had. I got the idea to build a quickie Viper out of the stuff I have on hand. I have 4 foam cores I choose the lightest ones and I cut the length to the size I want. Now I am laying out the spars and finding the wood to use. I should have a kit cut by days end.

I am going to see if I can spit one out a little faster. No guarantees but I get to test some other configurations. I might just like them. Snow is on the ground so I might as well do something.

I will post pictures later.

Onward and upward! Let's see...

I finished a horizontal tail, and you built a Schneider Cup stunter.
I contoured a profile fuselage and fit the wing and tail to it, while you built a Viper.
'wonder what I'll get done while you do this one.

I think I have about 3-4 of your work days left to finish the plane. 'may see air time by May. I'm delighted to watch your building posts. But wait! THAT'S why I'm so slow. Yeah, that's it. Ha!

fully sheeted.

Hey if still using electric power you can forget the  doping of the plane.  

 True, but a dope finish still has lots of advantages. A well done dope finish is still very light, it's easy to work with, and it's very tolerant to any repairs or touch-up work. Also, many folks here already have years of experience using it, so a guy might as well just stick with it.

Fuse is done and Stab and elevators are finished with 3 coats of clear. I am waiting on wing sheeting wood. And it will go together. Maybe by next week the wing will be done and it will be ready to assemble.

Progress so far. After I got the wood for the sheeting of the wing I did so.

• Wing sheeted
• Fuse built
• stab and ele finished and covered
• Wing tips roughed
• all horns and hinges made

 Is that a foam turtledeck?

sure

 A buck or...?

 I just noticed another thing, the cowl is going to be on the bottom this time? It looks suspiciously like an IC setup...

Looks like you'll have to wait.

 

Can you elaborate a little on your process for sheeting the foam core wings.  
Also in the "Foam vs Built-Up" thread you mentioned not using a spar in the foam cores.  Is that a common practice ?

Is that Canbon veil at the wing joint??

Today I did the knickknack stuff. Plywood bellcrank mounts top and bottom. Mounted the stab and finished the pushrods. Got the motor set and mount glued in. 1 coat of clear on the wings and stab. Its moving right along and should be all together by Monday. I need batteries for the camera so it will be a day or two for pictures.

No batteries yet but I am almost done with the wood work. All that's left is turtle deck, canopy and rudder. I am quite pleased with the way my FREE plane turned out. Well nothing is free but this is built from my scraps and I have enough scraps for one more.

You never know I will fly all my planes and this could be the best. If according to the masses that a heavier plane fly's better which I doubt but this will really tell. I am thinking it will be around 5 ounces heavier at 60 ounces when finished.

  As mentioned in the other thread, all of our foam-wing planes came out stiffer and much more consistent than the equivalent built-up that was otherwise identical. It's hard enough to trim these guys, it's even harder when it changes from hour to hour.

 Lookin' good. What's the wingspan on this one?
