1/5th scale plans are ready for shipping. Interested in seeing them?

1/5 scale rocks! I've just blown up some 1/6th scale BE2c plans to 1/5th (88" span) and it really is the best. Now I need some 1/5th EIII....... and I have my 'combat double'

I could probably help you with a 1/5th E.V or D.VIII soon, but not an E.III (wing warper.

) although I'd would love to do a BE-2c one day also.
I wonder if an E.V ever met a BE-2c in combat...

Here's a link to my 1/6th scale wing-warping EIII. It is a heavily modified 40size BUSA kit.

YouTube - wing warp 1

And here is a pic of my 1/5th scale BE2c rudder. At its longest point it is about 320mm.

That BE-2c rudder looks very nice. Which 1/6th plans did you use? I have the old Roy Scott(?) BE-2e plans that were also used for Tony Clark's Practical Scale's now defunct kit. I once built the structure but it got bashed around while moving too often, so I sold it. You could tell its age, but even in 1/6th scale the size was quite impressive.
Your wing warping E.III looks very nice also. I'd be interested in finding out how you did it and how it flies.

The BE plans are by David Hurrell (Traplet Publications).

As for my EIII go to page 37 of the "What's on your building board" thread. It flys really well. At least after I reduced the rudder to scale size (people told me you had to make it a lot bigger as the wing-warping was so ineffective) and reduced the amount of rudder coupled to warping (from 70% - 30% again it was high to begin with because people told me that it would fly basically as a three channel as the warp, particularly on such a small model, would be very ineffective). Now it flys no differently from any WW1 aileron model I have.

Yes, How can we do that?

Great day today! We've finally got the vacuum forming molds for the Pup's and Fokker D.VIII cowlings. Hopefully we'll get the first test shots very soon.

Chris, I have had an opportunity to completely review your plans for your 1/5th scale Sopwith Pup that you sent to me and feel they are extremely well done, thorough and executed with a very high degree of common-sense. I really appreciate these features in a plan. I would think a .80 to 1.00 C.I. displacement 4 stroke to be adequate power and certainly a 1.20 would be more then ample. A two stroke .60 to .90 should be great power, also. Since I’m not interested in the latest trend of electric power, I can’t make intelligent referance to this power source.

Thanks for this opportunity to review your plans! I look forward to building this airplane! Maybe this coming fall, I will start.
