Denny Sumner shared his beautiful AcroStar biplane. He scratch built it from plans from a 1973 Radio Control Modeler (RCM) magazine.
He had the wing ribs and formers laser cut. It is excellently covered with Ultracote, except for the black trim, which is MonoKote.
He has a build thread on RC Groups.
Originally designed for a glow .60-size motor, his power system consists of a Cobra 4120/14 (710Kv) outrunner, Scorpion 70 Amp ESC and Castle Creations BEC. He plans to try both an APC 12x8E and 13x8E prop to see which works best.
With a 4S 5300mAh LiPo battery, it weighs 5 pounds 14 ounces.
The bipe has 820 square inches of wing area for a wing loading of 16.51 ounces per square foot and a wing cube factor of 6.92.
Ken Myers shared two Dollar Tree Foam Board (DTFB) planes that he had built.
The first was a highly modified and enlarged FliteTest Old Fogey. His version is covered with TopFlite EconoKote and uses a Cobra C-2217/20, 72g, 960Kv outrunner with a 3S 1000mAh LiPo battery.
It required a lot of work to get it to fly well, but Ken now uses it as the introductory trainer for the club.
He noted that the FT Old Fogey, as designed and available on the FT Web site, has some serious flaws that lead to many folks not being able to fly it. The flaws include a vertical fin with not enough area and a rudder that is too large. The recommended CG is also incorrect.

The second plane he shared was his self-designed DTFB Ugly Stik. It uses the proportions of an Ugly Stik. It features a true Clark-Y airfoil. It flies well and was easy to build.
He brought the planes to encourage folks to build not conventional material planes for the Mid-Am's new event and award, which was noted in last month’s Midwest RC Society Monitor.
Roger Wilfong shared two planes he’s been working on while recovering from his hip surgery.
The Mountain Models Art Chester Jeep is built from a kit.
It has a wingspan or 16", wing area: 58 sq.in. and a flying weight of about 1.1 oz. It uses a 'brick' type radio system from an indoor ARF.
It still needs a bit more finishing, but it is mostly done.
His Flying Models Sweet Patootie was built using plans from the June 2001 issue.
The vertical stabilizer is on the fuselage, below the "V" type horizontal stabilizer. Magnets hold on wing. It was originally designed as rubber powered model.
It also uses a 'brick' type radio system from an intoor ARF model.
He noted that it flies pretty well.
