I posted some pictures of the Stilleto on Nov. 16th. under "What is it?" when I started work on the Fuse while I was getting parts for the drive train.

Don't bother Rémy, I was there yesterday to pick Oracover for the Satan and the smallest prop they have for IC engines is the grey Graupner prop 5x2.

Ok, I will give an order over the Atlantic ocean...

Well, my 1/6oz. tank came in the mail, so I was able to finish locating and installing everything. Build is pretty much done. I just need to fill in the dings and smooth everything out, then paint. From the driver's side, it looks pretty clean:

I tried to make it relatively clean from head on:

Your plane looks great Mark

Mark, Your model looks fantastic from all angles! Thumbs Up

Yes it does. This is getting scary, I hope my simple scrap heap can keep up.

duke.johnson Thu Dec 19, 2013 11:40 am

Looks great!

Tested the pain pens today. They washed right off like the fingernail polish.

I guess I'll have to spray some paint into a jar, so I can use a brush for the trim.

I'm trying a new engine mount on Miss Ashley to reduce frontal area.
Trimmed the top off of a horseshoe backplate:

Cut out the fuse like a Tee Dee side mount and sunk the firewall to the doubler:

You guys are building some top notch stuff. I am going to have to up my game!

Love that mount Jim, excellent work.

Great job! That's how I had planned to mount mine initially, but since I cut the backplate down to where the 4 mounting holes were no longer there, I couldn't use mounting screws from the front. I especially like how you inlet the motor mount for the needle valve and the air inlet.

Thank you, I'm planning on putting a intake scoop around the needle to force air into the intake.

I wish I had all these great ideas to start with! Top notch indeed!

Jim, I was also thinking of making a ram intake, only this 180° turn bothers me a bit. What about the wire mesh on the air intake. Does that have a metering function or is just to stop rags an bolts flying in the engine?

Excellent built, very nice.

Removing the screen is the first part of hopping up an engine.

Phil is correct. The screen keeps out dirt, debris, and O2. I remove the screen and drill out the Venturi. The Paul Gibeault article is great. Are you using a intergral tanked engine or a seperate tank?

Jim

**RknRusty** Fri Dec 20, 2013 10:09 am

I've been pondering over how to add ram air too. I would love to rout it to the P-51's scoop under the fuse and maybe have a Tee Dee venturi, but that ain't likely to come to be. I think a short ram aluminum scoop just inboard of the backplate is easier and will look good too.

I have found that the inner protective cap from Right Guard solid anti perspirint will make a perfect scoop lol!

I opened the air channel some more.

WHOOO-OAH! What a nice looking plane that is there Jim!

pkrankow Fri Dec 20, 2013 1:02 pm

I just arranged to drill straight through the mount to allow my engine to breathe better. I feel drawing from a relatively large pool of relatively still air will provide for good performance, at least better than drawing from against a plank.

Phil

duke.johnson Fri Dec 20, 2013 1:05 pm

Great work Jim!

OVERLORD Fri Dec 20, 2013 1:14 pm

That's a beautiful plane Jim.

Thanks for the tips, guys. I'll be using a tanked engine, but after reading P. Gibeault's article, I would better change the standard tank for the larger one. Could I otherwise have problems for getting 10 laps + starting and "landing"?
