Title: Brodak's RYAN PT-21
Post by: Art Neto on December 20, 2015, 05:41:24 AM

Howdy,

Has anyone seen or built a Brodak Ryan PT-21? Is it suitable for F4B competition ?

Thanks for any info!

Art:

Obtain some three views (I'll bet there are a lot on the internet). Draw your own plans to the scale that you desire. In my opinion, most kits take liberty with the accuracy and the quality suffers. Scratch buildoing is the best.

Jim,

I agree about scratch building.

As for drawing your own plans.

Just line drawings of outlines can be drawn first with accurate scale outlines.

Kinkos can print them to the scale desired, THEN, construction lines can be added afterwards as per wood thickness and placement.

You will always have the clean original drawings to fall back on, especially if you change your mind about the scale desired.

Just a suggestion.

I have the kit I picked up while at Brodaks in 2014.   Also picked up a Merco .40 for it.   For any scale competition I think it is a starter kit that needs documentation before starting the build.  I would like to make mine the inline engine version.

   I believe this kit is based on a design by Frank Beatty, a member of our club here in St. Louis. Frank is a great designer and builder, and has had models published in the mags going back to the mid-fifties. I think the PT-21 was published at one time. I think John Brodak had always wanted to build one, and consulted with Frank on the design and having it kitted. John made the maiden flights on it here in our area, I think, and it was the kit that got him in the C/L scale kit arena. I have a kit stashed for one of these days. As for fidelity of the model to the real airplane, I would have a pretty good feeling that Frank researched it to a high degree when he drew his original plans. The Brodak website says it was drawn and designed by Frank in 1999. next time I see Frank I'll have him relate the story to me again.
   Type at you later,

If this is a design created by Frank, I withdraw my comments. Frank is an excellent designer.
