20 Apr 14 - The April 2014 edition of RC Model Flyer included a free plan for a powered version of an indoor model of the 'Dehn Ring Thing', which was a experimental glider in the early 80's.  Whilst interesting I decided it was a little too large for our indoor hall; I also wanted to re-use the equipment from a wrecked E-Flite UMX Extra 300 I picked up cheap.  Whilst working out the reduced size version I decided I'd just make a simple circular model, which was to use black Depron and look like a record.  In the end I made it a little larger than an LP but not so much it really shows.  Due to the tapering elevons the roll performance isn't great; it flies really well and is very controllable but rolls aren't possible.  I think a re-design of the control surfaces to increase the width is in order.
