Larry ... you going 6S? I think it will be fun with that power plant but for total mayhem then I guess the 5320 might be very cool. You seen the Fliton Extra 330 video with the AXI 4120? Its got so much power ... the Fliton is about only 6.25 lbs with a SA82. Anyways, its always more fun to fly electric, eventhough I love glo ... the EP torque and power:weight ratio is always much better. Just that its costly ... I am sure your ST will be great fun, please put the video up here.
