  CHEV VEGA blocks have been melted down for years to make pistons for the Big Block Speed Jobs ,when they were on 80% nitro and full pipes they were going through a piston every couple of flights

LOL, I have one of those rods melted down by Frank Garzon. Story was he melted part of a Chevy Vega block and poured it into a pipe. The thing looks crude. I never used it because uncle Henry gave me a piece of hi Si rod that he uses. Still have some of that too.

Enya makes a propeller nut that protrudes through the washer but does not require that the prop be drilled out. It gives about 1/8" additional thread engagement than the standard nut washer.

It comes in a variety of sizes and I have them in 1/4"-28 for Fox 35, OS FP 20/25 LA 46, etc and M5 for the OS FP 10. Order direct. Ken Enya is very easy to deal with. His batch production of engines is the only frustration dealing with him.

I hate to beat a dead horse but here we go...

I save all my Model Aviation mags to leave in my dermatologist waiting room every six months, maybe it will spark someone's interest. 

 This months quad copter fest is going straight in the trash. I'm not a multi rotor hater but come on...

It's supposed to be about model airplanes.

I don't disagree with you.

The flaps taper to nothing at the tips but I would think that decreasing the flap movement would help. As I said above, the Mark II was behind the developments being made at the time. It would still be an interesting project. I hope that someone will build one.

If you are looking for a 3 blade prop for a pattern look at the Master Airscrew three blades. They have a nice shape but are a little heavy in the larger diameters, but for a pattern that you can thin out then do up in carbon, its a good place to start.

If you want to look at some information on molding props here is Wayne Trivin's old web site with lots of information. Wayne and I flew together for several years, he showed me how to mold props. I introduced him to Windy and he showed Windy how to mold tanks and other parts.

Best,    DennisT

Is the Hobby Fastener Ruffy kit for sale?

Titanium has lower modulus of elasticity so for sufficient stiffness it would have to be a lot thicker than a steel shaft. so there goes the weight gain. Also, bigger dia also increases weight and friction losses of bearings.
And as a sliding pair, you can expect several issues with Ti surfaces.
Beryllium shaft would be nice Smiley

Hi Lauri,Thanx for the info.I stopped by the shop and the titanium was mentioned.I will talk to him about the Beryllium.We want to make it from the best materials even tho some may cost more.Is Beryllium hard to machine or not readily available?Trax

That being said, the pictures on the Mark II box sure makes it an appealing project! The canopy appears to be larger and still has the feel of the stitched canopy and not like a rounded bubble, which would not look as good, and in my opinion looks horrible on the original Barnstormer. The paint scheme is also sharp. Add wheel pants and it is a real looker.

Since it is possibly legal for OTS and certainly for Classic, I hope that we will see the Mark II in contests.  With what he has shown us flying a Ringmaster, Dave Fitzgerald would be unbeatable with this airplane!

   I wonder if it flew any better than the original?  With more flap than elevator travel, and no additional tail volume, it may not fly any better, and possibly worse.

That is a nice looking airplane. Looks like the battery tucks into the inboard side of the fuselage?
