How strict are competition rules WRT building to the original plans?
The original instructions and plans for the British Champ model:
http://www.ultraligero.net/Aeromodelos/C/champ.pdf these are very slightly different from the short kit I got from Bob Holman Plans.
Will the blueprint or the purchased kit take precedence or am I just grasping at straws and the rules arenít this tedious? I honestly have no idea. Iíve never even personally met or even flown with another modeler tbh.

Also is a laminated leading edge ok? I donít have 5/8 x 9/16 stock I would normally make something like that up with strips of sheet balsa.

Mkelly sparked my interest in competing. Im looking forward to it!

I havenít seen those directions and Iíve seen a lot of them. I like those instructions I see two items I will be using on my next propeller project - fiberglass and the back side of the prop drive mechanism.
Thanks again for all your help Mike.

Don DeLoach is a very accomplished Free Flight modeler.† He published an article on carving props for rubber models in the September 2008 Flying Models magazine that I've found very helpful.† The article walks you through calculating the block geometry, with guidelines for selecting pitch and blade width based on characteristics of the model the prop will be used on.

The article goes on to cover laying out and cutting the block, drilling, carving, sanding and finishing the prop.† I've used this method to make props for several models, with good results on all of them.

There's a later Don DeLoach designed prop block specifically for 22-24" span FAC models in the FAC library here:† http://www.flyingacesclub.com/PFFT/PropBlockbyDeLoach.pdf.  There are several other articles on prop carving in the FAC library that are worth browsing through as well.

I just called Bob and ordered it, heís a pleasant guy and helpful too. He mentioned he sells sheets of gussets for a buck ha! So I got some 32nd and 16th gussets as well as 5-1/2Ē fuselage build triangles.
Iím kind of stoked for when that package arrives...

I forgot that I promised myself the next build would be from a kit. I didnít want the burden of a scratch build since the last build was both scratch AND my own design. So before building the Eagle I plan on purchasing the Copland Streamliner short kit from Bob Holman plans.

Good points - I hadnít considered competing but i wouldnít want to box myself out of that in the future.
Funny thing, I moved here to SoCal hoping I might meet other pilots when I lived fifteen minutes from the Muncie airfield and never even went there.

Thanks.  If you want to compete with the model you'll probably have to stick with the construction shown on the plan.  FAC old-time rubber rules allow you to add things to the structure but require inclusion of what's on the plan. 

That said, if you want to depart from the plan I think strip balsa would be fine for laminating the circular formers, and certainly more than enough for the stringers.  Bass is handy as a tough outer layer on wingtip laminations, but it's 2-3 times denser than balsa and would pile on the weight quick if you used a lot of it.

Nice woodwork, itís a good model choice too.
What do you think of two layers of 1/32 thick bass strip for the hoops? And potentially the same idea for the stringers?
Thanks!

That'll be a great project RD!  Would love to follow a build thread if you choose to do one.  I'm building a small Zaic streamliner at the moment - a "Utility Special" from the May 1937 issue of Popular Science.  The plans for it are on Outerzone.  Finished carving a pair of props for it today - one per the plan and another higher pitch prop following Don DeLoach's style.

It is the Golden Eagle III. You can read up on it here: https://www.hippocketaeronautics.com/hpa_forum/index.php/topic,2554.0.html

It is based on an old Frank Zaic plan

My next build will be a streamline Wakefield. The one in the opening scenes of this YT video is near the top of my list however I cannot ID this aircraft or find the plans, I was hoping someone here could help.
Address of YT video:
https://m.youtube.com/watch?v=y7Ae0JN19AQ

Anyone know this model?
