Mike, do you want some tiny Sopwith strut logo transfers?

Bill that would be a nice touch.  You have a source?

Mick Reeves produces a sheet of Sopwith logos at FF sizes. The very smallest strut logos are a bit fuzzy but better than nothing. I've got a few left over - pm your address again

Here/s the freewheel I've gone with for this model.  It's a refinement of my earlier scheme which calls for the cross tube to be square lashed with fuse wire.  Here the cross tube is drilled through into a larger tube and the whole is soldered on the front of the shaft.  I slip a piece of gasket paper onto the shaft to protect the plastic prop during soldering and rip it out afterwards.  The washer immediately behind the prop is soldered to the shaft and takes all the load.  The prop itself is floating and this gives a very reliable freewheel - 100% guaranteed!  

I have used a jasco thrust bearing which again is a much better use of the nose weight budget than a heavy prop

That's a very neat solution Mike. It saves binding stuff to the prop and reduces the scope for flesh wounds with a Garami. I'm guessing it's best kept for small models as a simple soldered joint to the shaft might fail with a big motor?

You'd be forgiven for thinking that but even though the torque on the joint is high the length of the joint compensates for this.  Good soldering technique is important.  A hot iron applied to the work and when the work is hot enough to melt the solder you get a good sweated joint.  I have successfully used this freewheel with up to 4 strands of 3/16

Not wishing to appear needy at all but just wondering: I've posted a lot of examples of these sort of freewheelers on various threads along with the soldered plate taking the load.  These ideas are the fruit of my endeavours to engineer out the usual suspects that make life more difficult than it has to be.  I'm really interested to know whether anyone else out there has had a go these methods and how it went

When I finally get back to building, I plan to try your freewheels - my scaled up Fury will hopefully need one. I used one of your freewheel devices on the Nieuport Bebe, but its best flight so far landed gently on the runway with turns on. When I fly her with a meaningful number of turns, I'll let you now how the freewheel fairs!

When I get around to re-doing the prop/spinner/noseblock for K5083 I'll be trying out a variant of your Avetek f/wheel.

I've got it all saved away for future projects but am stuck with work and travel commitments preventing building at the moment. I really appreciate the designs though, they're very neat and practical.

Now there's an example of a kit scale model (albeit a painted one) that you wouldn't be at all ashamed to put in F4D!

It's a thing of beauty, is that. I particularly like the treatment of the stringered decking behind the pilot where you can just see the formers.

Very mindful craftsmanship on this build Mike. You have unlocked the vault of how to run that flying wire through the middle wing without it being a hole-tearer! I apologize if this is a redundant question but what is the weight at this point?

Many thanks for the nice comments gents. 

Jack, it's glided or glid.  Very slow and rock steady with a straight stall and no wing drop.  I was a little concerned by the amount of incidence on the top wing as designed so I reduced it slightly by the double expedient of washing out the top wings a little,  which also gives me the lovely straight stall.  I plan to try her on 4 strands of 3/32 to start with.  This would have been over our long weekend just gone,  but we ended up with torrential rain and howling winds.

Crabby the final weight ready to go is 40g ballasted which is about 5g heavier than I expected but I did go to town a bit with detail.  Even so its pretty acceptable - lots of wing to carry it.

It's lovely and that seems like a very low weight for such a detailed model; c.f. my "no detail whatsoever" Camel which came in at that weight or thereabouts trimmed.
