I fly mine with a p80 ( around 19 lbs ) Im pretty much always at full throttle, as i fly it very hard. I used to fly the plane without the ducting tube and max i was hitting 150, maybe just over .. and this was pushing it .. I installed the ducting tube through the fuselage, and now i have noticeable speed gain, and am *****g out at around 170 ( again, pushing it out of a shalow dive) I think the plane slows down really well, and actually needs some power out of the p80 on landing to maintain slow high alpha nose up altitude. ... Also, if you fly hard through turns, it bleeds of speed FAST ! as the wing becomes an airbrake, so more power is very usefull here .. I have been able to slow my grippen from a 150+ mph pass to almost it stalling out of the sky in a matter of a few seconds by pulling hard vertical on the elevator with a lot of canard ... i guess it all depends on how the airplane is set up in terms of thros and CG ...

one thing i dont like is the way landings are sometimes weird ... if you pitch the nose up too hard on the flare, and adjust by letting off of some of the elevator, the plane tries to get back on step hard, and tends to baloon once you let some of the elevator off .... so in high alpha landings, you have to be right on both your elevator and power ...
