Dominator and Jett 50
A Jett 50 on the Dominator will put you pretty close to 150 mph, maybe a little higher with the right prop and weather.
The Arf version of the Dominator would get you in the air quicker. Its called a Predator 500 and I saw one fly about 2 weeks ago with a Sport Jett .46 and the plane held up well. The Predator needs a little bit of modification for strength, but is a good overall value.
