JR,

The direction that everyone at the AMA seems to be trying to turn with the 45# thrust engines is that the modellers wanting to use them desire more thrust to go faster. I personally want a bigger engine for a particular model I am building right now, I wasnt to run it at 35# of installed thrust and with that engine I will be running it at lower rpm for ultimately more reliablity and longevity of the engine. I am currently flying a 35# thrust engine turned down on another airframe for the same reason. For some reason Dave Brown and others automatically assume that we want 45# max thrust so we can go that much faster. It just continues to demonstrate the lack of understanding that some of folks have of the jets. If it takes installing a speedlimiter on my airplanes to keep the airframe from exceeding the VNE I'll do that for my own peace of mind and not just because I am mandated to do so. This issue is all about common sense and Dave Brown etal.... are trying to assert that every guy that operates tubrines does not have the maturity to know when fast enough is fast enough for his abilities, or for the airframe he is operating. Just because 120 mph is the limit that abel-pranger feels is the limits of his abilities does not mean it is the upper limit for some of the rest of us. I feel quite comfortable flying at twice that speed. You can't regulate common sense.

BTW Abel......very good post.
