Throttle is everything and I do see people struggling to manage that, but done right the result is stunning. A lot of scale jets will be in the 450-500 knot cruise speed range, At 1/5-1/6th scale that is very slow, I agree we have to increase the speed a little for the correct look, but itís still very slow compared to what many are used to. My DerJet Vampire is perfectly powered with 32lb thrust, most of the flight is 1/3 throttle stick position, but as soon as you pull the nose up power is slowly applied and the speed pretty constant. This model un managed is like a Super Bandit as itís very slippery.

The type of turbine will also affect that, the higher efflux speed types donít work so well in scale jets.

Dave I see your point as well but the thing is with more power means more fuel and allot more weight. This means more speed and the scores suffer.

My my first year having a very under powered aircraft at top gun I won my class. Before with jets with good power best I could do is 12th.

My F15 weighed 75lbs full of fuel and had only 45lbs of power. It flew very scale like. The results speak for themselves. Also like I said Peter Goldsmith has been Mrtopgun several times and all with underpowered aircraft.
