I am a brand new customer for a turbine.

The small package, miserly fuel consumption and (hopefully) smaller price tag gives the small ones an edge, plus the reduced diameter allows more cooling/venting air to pass over the turbine in enclosed installations. The downside is the high RPM and concern for bearing life. ...and the noise! I have heard 3 different makes of small turbines running, and all of them produce a sound level that is unacceptably high for my tastes. The little guys have a place in smaller models, but I sure hope some efforts are made to quiet them down a bit.

So, a big turbine loafing along at 12lbs thrust will fill the bill, and allow me to grow into larger models sometime in the future. Availability, and convenient service nearby, but some technical features that appealed to me, led me to choose the TJT 3000. It should it here real soon...
