Hi Gang. First ever Weatherman with a glass fuselage is finished. Engine is ex Konrad Konrad Pylon K&B .40 RIRE.

Cheers,

Doc.

Just for the record I never massaged that engine, it should be close to box stock. It is interesting to see the cylinder finish with that engine. I don't think K&B were totally comfortable with the idea of micro cracking of chrome.

Have you tried the inlet cone idea?

Also that prop look like a lot of wood, tips need to be thinned.

Thats a mod that certainly will be done before flying Konrad - thanks again for that.

I'm looking at props - I'll probably make a couple of moulds and turn out some carbon ones.

Doc.
 
I use to carve props out of wood to find the best fit. I would then land very carefully and use the good props as a blank to make my molded props. As the carbon props were stiffer I found they had more pitch than the wooden prop. To get back into the power band with the composite prop I could thin them down a bit. Carving props is another of those long lost arts.

I have to admit most of my composite props were glass. But I did thin the blank a bit as I knew they would hold the pitch more than the wooden ones.

The way I made the props I still had to do a lot of clean up. So, I had to deal with the fibers all over the place.
 
You know you love it!

P.S.
If the lugs say Lee Custom that 6.5cc wasn't from me. I think I did send you some K&B 6.5cc rear rotor engines but those were stock K&B. I did send you one or two 7.5cc rear drum Lee Custom engines

P.P.S.
Nice looking ship!

The 6.5cc engine is for another class VI plate set on the same model, Konrad.

For class VII I'm using the Konrad/Lee 7.5 you sent me...And I am going to wipe any vestiges of a smile off those smug bugger's faces...just like I always do...

Let's not be too Hubris. :eek:

Love the carbon print!

To be clear the Lee Custom K&B 7.5cc rear drum has little or none of me in it. I asked Lee to set up this engine for the Kress 740 ducted fan using low nitro fuel (15%). This was in the late 90's. I flew a Turbax with a Konrad K&B 7.5cc rear rotor with high nitro at 6K feet and didn't want the expense with the fuel and one OPS 3000 plug per run. With the new 7.5cc rear drum I asked Lee to make a bit more reliable engine. That is the one you now have. To be a barn burner you might need to rework the head for higher nitro fuels.

At around the turn of the millennium I learned of the WeMoTec fan driven by 30 round cells and left the smell of nitro for electron smoke! This is why that Lee Custom was still NIB when you received it.

Thanks Konrad. Curious what was your interest in DF?

LOVE the "Electron Smoke" going to nick that one from you!

Cheers,

Doc.
 
That's going back some 30 years! As I recall I had a Jet Hanger Mirage III. This was a precursor to my building for electric. That is I was a weight weeny as I built this with Sig Contest grade balsa and Viojet carbon strips.

I also had a Balsa USA F-86 that I added an airfoiled vertical stab to try to help recover from a spin.

I see I have another Paul's Fly Stuff, F-86 kit (same as the Balsa USA kit) and a Knights of the Air, Saab 37 Viggen kit collecting dust in the garage.

Wow..fan-tastic...sorry...
