I wish the price was a little lower, this looks cool as heck, have you contacted Super Tigre with your design? Maybe they would start carrying it[8D]
As for power, I'm not sure how you can say it makes more power then glow. My ST G90 turned a 14x7 APC at 10500 RPM on just 10% nitro, a 13x6 APC was nearly 13000 rpm, engine began to over rev.
Whats the rpm on a bigger prop because 13x6 is fairly small for a 90
