Sky Hero

High wing sport 40 size glow model from GWS. The Sky Hero is designed with a semi-symmetrical airfoil for the sport lover yet retains plenty of wing area keeping it suitable for a first trainer. I actually own and fly one of these as an electric model as it makes a good conversion project. Learn more about this model in RadicalCast #007.

Specifications GWS:
Length: 1380 mm (54 in)
Wing Span: 1530 mm (60 in)
Wing Area: 49 sq dm (760 sq.in)
Flying Weight: 2500g (88 oz)
Wing Loading: 51 g/sq dm
Recommended Engine: .30 to .50 2 Cycle
Recommended Prop Range: 9x6 to 11x7
Radio Required: 4 Channel, 4 Servos

Notes about setups:
#1 is a setup I designed to prove out an exceptionally low voltage system that would actually work well in a 40 size model. It's well balanced and performs much like this model would with an OS .40FP. I consider it one of my highest technical accomplishments. Low voltage is an often repeated mistake. This was my attempt at making the typical "mistake" a sucess. If you like trainer aerobatics and flying on the wing, perhaps you'll enjoy this setup as much as I do.

Setup #3 is an alternate way that I fly this model. More peppy, more aggressive performance for a motor so small. It really optimizes a motor normally considered too small for a 40 size glow conversion.
