The JL T45 is the same size as the Ice Mouldings kit i.e. 63" span so any 54 size turbine should be fine. I do recall you fitted a 54 into your 1:7 Thorpe Hawk so the Supersport should not be too much power for the JL T45. The big advantage of the SS is not so much the extra power but the much faster spool up particularily from about half throttle.

As I am in a hair splitting mood it is nice to see an actual T45 with some of the scale details such as the airbrakes etc. As I am sure you are aware the SM T45 does not differ from the SM Hawk other than in the ARF colour scheme.The full size versions differ substantially.

At least in this instance we shouldn't have SM jumping down JL's throat about who designed what!
