My first jet and my trainer for turbines is the BVM Bobcat, it is my turn and burn jet. I trust that plane completely and I can fly it however I want, very cool! I also recently purchased and have been flying a Yellow F-15 with a Jetcat P-120. The one thing I don't like about the F-15 is the difficulty with flying in crosswind conditions, I will fly the Bobcat in any kind of wind however. Having an exposed engine with no tail pipe is a huge advantage also for getting used to turbine operation.

I love scale planes, but my recommendation is to get a sport jet and learn about turbines, then get the F-15. You will always want to keep the sport jet around for practice and flying in less than perfect conditions.

Below is my Yellow F-15 and my BVM Bobcat with my 1940 Comet Sailplane for comparison of the old and new!

Good luck with whatever you decide,

Luke
