Father Son Turbinator build
First posting on this site for a build log My son and I are building a Turbinator. He cut foam cores and we are going with a 3 piece wing and
Wing tips will plug in. I am building fuse and tail surfaces.
We do not like the looks of the inlets and are redesigning. Is there a general rule of thumb how much air you need for proper cooling of the turbine?

What size are you building?
I am fixing to start on another 125% Turbinator in the next few weeks. I got all the laser cut parts from Bob @ LDS.

I have thought I might modify my inlets also, but have not decided. I know the standard size was been modified to look more like a F2H Banshee by rhklenke.

Howe do you folks generally finish your Turbinators? I´m building an all wood version of the Turbinator and I haven’t decided if I´m going to cover it with glass, epoxy and paint or if I´m going to cover it with Oracover. Do you usually build the long winged version or the shorter winged version?Merry Christmas from Sweden Jannica

The fuse we didn't care for the top deck, We wanted a sport jet look. I made new formers and sheeted with 1/4 x 3/16 strips. I had to bevel each strip to allow for a good glue joint. Aprx 10 hours of work to glue strip planking on and two hours of sanding. A lot work but it turned out nice. Today I tackle new intake ducts.

I will be covering mine with Ultracoat, my goal is to keep it as light as possible, painting adds weight, it is a much better finish but makes an airplane heavier. For the wing I decided to add the extensions on the tips to reduce the wing loading, my thoughts are that I will also get more lift during the hot summer months when the trust of the turbine decreases because of the heat

Carved out the new intakes today. They are 1 inch over size in the front and 1/2 at end. Will glass one intake and lay up one intake and see how it looks temporary installed. A-4 type duct, there will be no wing fillet on fuse.

The intakes I made didn't look right so in the garbage they went. The intake liners are 3/16 soft balsa with 1/64 ply glue on for strength.
Side of intakes are 1/8 lite ply. Tomorrow work on right side intake. Like the look in new intakes, reminds me of F-15.
Intakes will blend in with wing.

Intakes look great dad!
The wings are coming along. Here's a pic of the wings taped together with the servo boxes in, wing tubes glued in, and landing gear blocks glued in. I made up some 1/8" wing spars and glued in the 1/4" x 1/2" spruce spars tonight more pics to come.

Great work, always a pleasure to see a model made from trees rather than another plastic fantastic.
And, as you guys know already, you can modify them easily to make them a little different because
you develop the skills to do that when you build them.

Spruce spars are in, root ribs are cut to accommodate the 1/2" dowel and spars. I glued it and clamped it to my table to keep it true. I have one more half rib to put in and it will be ready for the skins.

The intakes are done! Top of intakes have pink foam glued on. Sanded them to shape and applied 2 layers of 6oz glass cloth
with West System epoxy. All the control services have 1/64 ply glued on trialing edges for added protection against hanger rash.
Fuse is getting close to completion. Stab will not be mounted until wings are done and we check incidence of stab and wing
