Thank you Mr.Matt for the IM expressing your concern. I have to say that I like the 17.5# thrust that the P-70 offers as far as using it in larger planes later and the extra power it would provide on the Reaction 54. This and the Jetcat reputation for quality and customer satisfaction is how I made my choice for the Jetcat. Sounds like the perfect choice for now and later, however I am without an engine and the JF-50 Bee is in stock , cheaper and has a lifetime warranty. Hard choice here.
