Exclamation New Plan -- Esquire

This is a kitbash, with parts added. Start with a SEMROC Squire for most components. You'll need to add a long 13mm motor tube, a TB-5 thrust block, four CR-58 rings, and the 3/32" hardwood dowels.

I took the Squire fins and open-framed them, then skinned them with label stock and CA. The forward fins came from the stock sheet, but were trimmed down to match the angle at the top of the main fins, so that the dowels would have a support. Cut the rear ST-8 at 4" long.

The motor mount only needs to be a thrust block, but you can take the long hook and the TB-7 that comes in the kit and still have a working hook retention for the 13mm motors...

Length: 19.70"
Diameter: 0.908" (ST-8)
Fin Span: 5.31"
Weight: 1.17 oz

1/2 A3-2T......90'......Dv 2.2 FPS......36" x 1/8" rod
A10-3T........225'......Dv 7 FPS........36" x 1/8" rod

The Squire kit makes a nice starting platform for many designs. Carl has at least a dozen variations shown in the instruction booklet just using the kit parts alone.

Enjoy!
