Lonnie, how is this for a precise wing saddle, and my only cheat on this plane, the wing bolts were going to sink into the sheeting so I place these one inch by one inch squares of 1/16" ply. That stuff is so hard it literally takes a hammer to dent it.

I nearly took a shot at building this Stipa-Caproni, the designers expected it to go fast aided by the Bernouli effect making the prop more efficient. But, it refused to go fast, 83 mph was the most it ever saw.

The Stipa Caproni was a very innovative design. The first of ducted fan concepts and led to many more designs. At least it didn't break in half on landing. The Stipa ducted fan flying wing designs looked very cool too but were never funded for prototypes. Would love to see a Stipa Caproni model powered by a small Saito.
The blue/yellow Stipa Caproni in your pics is a 3/5 scale that had two recorded flights.

lol. a Saito would be the perfect engine for this plane. cause both have the old-time classic look.
Why "almost"? Go for it. Not getting any younger.
Looks like just the plane for a windy day, a barrel of fun.

OK here are the tail feathers on the Sky Raider, covered pretty well, me thinks. The tail wheel has it's own control rod and is connected inboard of the rudder control rod to reduce it's travel. I opted to not make my own tail wheel assembly as the plans call for. It has a nice Saito look doesn't it. Only the hinges are glued so far. I'll remove the tail feathers to cover the fuse.
I borrowed this idea from one of the builds at OSMW

A buddy of mine asked me to post something for sale him. I posted it over on RCG but I got to thinking, what size engine do you think would swing this much lumber?

This DA 70 would be perfect with the prop set at 9 or 10 inches of pitch: https://www.desertaircraft.com/colle...products/da-70
This Saito 73 comes close ; https://www.horizonhobby.com/product...SAIEG73R5.html

The Saito FA 40-a is anxious, the tail feathers are covered and connected to their respective servos, they're not glued in place yet, today I'll remove them and finish sanding and covering the fuselage. I'm also considering moving the wheels inward and hacking off the excess axle. It sits tall doesn't it?

I'll check that prop clearance out in a bit.
Nah, the wheels just look weird way out there, even moved all the way in it will still have Pontiac's Wide Track.

will do. Yea, she’s old and had some time befor I got her. The old bird is a test bed for my B-25. Want the kinks out of the systems before that flies. This set-up is close to solid…. But need to chase down that miss. Getting a tach to see how it dials up and responds to c=some nitro!

That said, engines with higher compression ratios, eg early Saito 65, 80,150 and 200Ti, will see a more significant power increase with higher nitro content when used in conjuction with a more advanced static timing angle.
Give it a test run with nitro and let us know what you find.
