Super Slinky



This was a free plan in the January 2013 R/C Model Aeroplane magazine, by Alex Whittaker, including
 "...ye olde health warning. Super Slinky is the Yorkie bar of simple sportsters. She's not for girls, the faint-hearted, Guardian readers, those of a nervous disposition or Southern jessies. She's no trainer, follow-on trainer or first low winger. She's for experienced pilots, aerobatic hooligans and unrepentant throttle benders. The truth is, she's a very bad girl."

With a warning like that, I couldn't resist. The original idea of the plan is a very quick build. One type of rib, box fuse, plank tail. Of course it took me 3 month, using stick-build tail, one extra wing bay, and in general every attempt to not rush it.

Wingspan110 cm
Length90 cm
Area27.5 dm2
Weight1275 g
Loading46.4 g/dm2
AirfoilSemi-Symmetrical
EngineOS 25

First flight was on 2013/08/01, thanks to Bill L. for providing the wing rubber bands! Very easy to fly, maybe as a result of slightly larger wing and CG abt. 2cm in front of main spar, since several internet posts warned about a CG that is too far back. Later used the "Brush Script Std." font as template for wing marking.
