"Faux-Que" New Design Build Thread

Fantastic interest thus far!

The most descerning and historical oriented readers will relate to my inspiration for this most serious build thread.

Hanno Prettner

Wanted: Rotating spoiler details wanted!

I am interested in attempting to recreate an unusual feature utilized in the last Tournament of Champions in which conventional sized pattern models of the era, were flown. Specifically, Hanno featured a variation of the Curare' with his flap/spoilers and (2) spoilers which rotated out of each wing. The spoilers were placed outside of the flap/spoilers, about the high point of the wings and had about (2x) area protruding from the bottom of the wing as the top. I believe Model Airplane News, the magazine sponsor, featured photos and drawings by Jim Newman about the TOC. Any original photos or drawings would be most helpful.

The following details have been sourced and engineered except as noted:

Stab design: The Zeque and Integral both have a unique outline. Each is rather square or constant chord and have a very straight trailing edge relative to many current designs. Material will be added to the leading edge of the elevators and reshaped.

Anhedral: I will use the same angle as my new oxai-Beryll stab. Per a conversation with Dave Guerin, I will calculate the new mean aerodynamic chord and move the stab location "up" to retain the stab/wing/thrust decalage. A properly balanced Focus II requires a minimum amount of elevator mix for rudder application in knife edge.

Wing: The wingspan will be shortened (2"), additional trailing edge taper at the wing tip 1/2" and 0" at root, a much more blunt leading edge and the identical tip design used on the Brio (5" radius). The Hanno flap/spoilers will be added as well a serious consideration of how to engineer the nifty rotating blade spoilers.

Fuselage: The canopy will be moved forward to the rear edge of the cowl, 3/4" added to the top, 1/2" added to the bottom from the trailing edge of the wing forward, Oxai-Beryll cowl shape in the front, Zeque shape for the top of the cowl, (1 - 11/2") sub fin beginning at leading edge of stab, fin moved forward similar to Oxalys, Zeque and Astral, Zeque landing gear and wheel pants.

Canalizer: Full size templates from CPLR Oxalys and construction methology.

Weight: The reduced wing area will require the model to weigh 10.25 pounds or less without fuel, requiring lots of lightening holes etc. The additional servos to move the silly flap/spoilers let alone the rotating blade spoilers will quickly add weight.

P.S. 3DnSD, Dave Guerin gave me permission to post the photos of the "JFM", as he has for other projects. Thank you for your continued inspiration and greater appreciation of my efforts in english class.
