I have a pair of recently acquired new-in-the-box K&B Screamin' .48 engines. I bought one off of E-Bay; it was made before K&B was sold to MECOA/RJL. The second is a brand new one ordered from MECOA. The two engines are identical and MECOA doesn't appear to have altered any part of the original design.
We've been doing some non-sanctioned club pylon racing over the last couple of seasons running .40 to .48 2-strokes of all makes. Last year's winner was an old .46 FX with new bearings. This year's winner was a K&B Screamin' .48 engine. The .46 AX engines are always very competitive, but they haven't won. The Thunder Tiger Pro .46 is also at the top of the class for truly competitive power.
I haven't had a chance to fly my Screamin' .48s yet, but I'm looking forward to taking them for a whirl.
