Call Larry Wolf at JHH he will tell you anything you want to know about the Turbax fan and the K&B 45.

Impellor and shroud will work, you may need a new turbine body for the different engine.

impeller is the same , just the engine mount its different ; if your going to use thAt engine , you will have to build the airplane very light , BETTER IF IS a relative small plane , like the jhh f-86 , JD F-4 , ECT ; THE NEW KB .45 ( rear carb ) flew my a-4 very well
if you can get a KRESS RK-740 , THAT ENGINE fit PERFECtLY , put it in a electric jet factory f-86 ( formely house of balsa ) f-86 , you will have a good power to weight ratio

ASR,

I hate to say it but... do not use that engine in a ducted fan! Save that one for a fast prop plane like a diamond dust. There is a K&B rear carb for sale in the classifieds. This will save you countless hours and possibly a plane. The front carb engine is first generation and doesn't have a history of running reliably.

The K&B 45 has been sold pending founds, but I have another one with the fan used in very good conditions + pipe for sale, this engine was flying a JHH Mirage at 13 lbs and I could do loops, no problem.
