Construction differences aside, which of the two Laurie Barr designs do we think is the best performer?

Hi Gary

I would pick the Scram every time, but I've got one Cheesy What I would say is they are better to build without the struts - my opinion anyway!

Cheers

Hi All,

Does the Scram have a 28" flat span wing span? I ask because I have to scale up the plan on Outerzone in AutoCAD to true scale. Thanks

Bill, I'd forgotten about that! It was one 'modification' he didn't get away with!

I fly the Scram "as is" and it flies really well...use the airfoil as shown in Laurie's article in Sam35 Speaks and don't forget to light the D/T because I lost mine last Monday testing on my small field...it likes to bump up in a slight stall in lift...I was a little skeptical about the prop hanger (and my soldering skills) but it works really well and I was under-powering it early on...and it looks SO COOL!!!!

I found that a 10mm wide strip of heavyweight modelspan right on the leading edge (and the same colour as the local jap tissue!) worked just fine...

Hi Gary

Have you decided which one to build yet?

I remember when this was hot news-in the aftermath-and several years later- I wrote to Laurie Barr asking his thoughts as I was underway with building a Pinnochio-(the tattered remnants of which are still in a box somewhere!) -I received a nicely worded handwritten reply to the effect that at the time these lightweights were designed, and being built in abundance, people were experimenting with turbulators, and he had himself used them on occasion to sort out a 'difficult' model-but not as a matter of course.  I found the Pinnochio if built to the plan to be an absolute shocker for bunching at the rear peg-the fuselage is far too narrow for comfort at that point-and never really persevered with it.

I'm going to go for the scram I think...I'm in the middle of building a couple of models for a friend, an 80" Playboy old timer and a Kwikfli III. Both RC and taking up all my bench space...then I need to do the metal work on my two vintage coupes....and I've just finished a Vic Smeed 'pulstar' for single channel to be sent to the UK for the Pontefract retro 'do'....busy, busy.....I don't know how I found the time when I was working!
