RE: K&B Sportster .65 (target drone engine)
Anyone compared the flights of the Mig powered with the plain bearing HB .61 to the K&B .65? I think the HB was fitted to some of the target drones? I have an HB .61 (with BB) and both a K&B .61 and a K&b .65. I have flown them all but not done any comparisons. Thanks.
