It all starts at the 1:1 with it's intended purpose and how it evolved to become our muse. Thank you for the perspective. The honest encouragement of your post has me now building (planning) a basswood plug for a nosebowl mold. A friend is a wood turner. Aluminum flashing will complete the cowl shroud. Luckily I have the correct pants in glass. The shallow blisters may end up vinyl graphics. The intended 3W150B2CS with 32X10 Menz 2 blade CF will have it's day after all.

Steve flew the Samson for 9 years after it's 1985 completion and stated it was his favorite airshow performer of all. It was Steve's with the colors of Ben Huntley's that inspired me many years ago. I will proceed with that one in 1/3. Thank you. A fellow in Australia built an excellent large RC example of Wolf's version many years ago. Photo is Wolf's 1985 Samson after Bobby acquired it. Thanks again Whiplash48

Can't wait to see the finished airplane sometime. When we were looking for a biplane subject to do for the '84 TOC, I had no idea there was a Pitts Samson. A good friend and fellow pilot suggested the Stearman as an obvious choice. The two have a lot in common.
Attached is my attempt at a set of plans for the Samson in your picture;

I started these back in 2014 as a possible IMAC/TOC biplane build.

I have a DA-170, I may just have to start cutting some plywood for this project...

I can't wait to have a half built airplane. It has been a long time coming. I'll post a progress photo. The Stearman is a personal favorite. I built the 64" Sterling Kit when it was current. It was a Giant Scale then. And I was just a kid.

Pitts S2-C 3 views

These came from a binder at Christen Industries. They are not available on the net. I assume they are accurate. In comparison to 3-view of a Pitt's S2C owned by Brett Hunter, a single seater, it appears all are correct. A series of 3 views from Aviat of the S2A, S2B and S2S many years ago looked nice but were not accurate for the purposes of scaling a model from. Likely to protect their proprietary products. Model Building has taken a karmic hit in last 2 decades. I hope these are of value to someone. A Ryobi S2C ARF had the only 3 view available around 2003. I charmed these out of the girl that answered the phone at Christen in 2006.

Brett Hunter's is attached for reference.

I do not know to be honest.

[QUOTE/ MB - -can you help with this Question?
Flight Wise what would the difference between an Ultimate and a Challenger II?, Which would be more docile, Land slower etc?[/QUOTE]

Hi HODGE, I can't honestly answer that one. I have not flown the Challenger but I am going to guess it would land slower than the Ultimate all else being equal.

I have my Ulti from 2005 and I fly it every year and I haven't yet been able to overshoot a landing, but always needing to drag it in under power, but then again I don't have an ordinary Ulti, meanwhile my Christen eagle or Pitts is generally cruised by the pilot boxes on landings

Sport Aviation Article October 2015

A great article for Pitts enthusiasts. It was to large to Post. Whiplash48 remedied that. Thank you. All issues were sold out immediately. This prints off nicely for those who collect.
