Jetadic, this is what I was think of regards to the weight of the DF setup compared to the 700. The Shark weighs in about the same as your Viper so the 700 should be good I guess? I have not a clue about turbines but the 700 states 7lbs thrust right? I assume this is full throttle?
I guess most guys don't fly at full throttle but wouldn't you really need mostly full bore to the fly an 11lb plane with a 7lb thrust turbine comfortably?
Like I say, I have no idea! :stupid:
