Congratulations on your solo!!!!!!!
But here's some words of advice.. I believe the JETT motor was designed to rev... Therefore doesn't care to sit at idle.. Doesn't like to swing a big prop slow.. But likes to swing a small prop fast and stay wide open.. In my experience this is how they've been. I don't know if this is true with all JETT engines or not..
So If your not wanting to go fast... Check out other motors.. But from what I've seen... JETT is the best of the best to go fast and turn left with!
First off..
TXAGGIE - Congrats on your solo !! Welcome to the world of R/C aviation 
There are so many aspects of this sport to learn and enjoy. I remember my first solo flight. I had performed "solo" flights a few times with the instructor at my side. One day I was flying, and the instructor went over, sat on the bench with his coffee, and told me to "land it". I dinged the prop, but it landed right down the center of the field.
Ice_Man,
What you posted is bad information. Not true in the slightest. Unfortunately, you are not the only one with that same information.
Please visit
www.jettengineering.com for detailed and correct information.
Yes, Jett makes racing engines designed for high RPM without concern for idle or transition. Both the QM40 and Q-500 BSE-40 engines have done very well in competition in recent years. Mike Helsel won the Q-500 NATS just a few weeks ago.
However.....
the vast majority engines Jett sells are SPORT engines. All of the Sport-Jett engines idle, throttle, and transition extreamly well. In fact, the Jett carb is one of the most popular after-market parts (used on other engines) that Dub sells.
The design of each is based from the racing development, and as such the engines tend to be bullet-proof and very smooth running. And yes, they tend to produce more power than other engines in their size class.
Jett makes engines for every application imaginable. Yes, some sport engines are available for high rpm and speed applications (but they still idle and transition). There are other engines designed for big props/low rpm used in 3D, scale, and aerobatics applications. The smaller .25 and .30 size combat engines txaggie noted in his original post are a good example of an engine taylored to an application.
For general sport flying with a little 'kick', there is nothing quite like a Sport-Jett .46 with a 10x6 or a SJ-90 and a 12x6 pulling a Kaos or similar around
Ok... of the soap box
Take your time there txaggie
Gets some stick time in. The more the better.
BTW... Dub Jett holds a Bachelors Degree in Aerospace Engineering from Texas A&M
