Re: Aurora B-25
Yes,
K&B designed the Aurora Tornado engines and in '60 Aurora bought K&B, they needed more pop to pull larger plane, so in '60 they intro'd the B-25 with new .060 engines, stamped 'K&B .060' on the bottom of case.

Great!
You have an awesome plane there. I'd really like one for my collection as well.

Re: Aurora B-25
Nice mint condition B-25, Hadrian, congrats. It is amazing the quality of items 57 years ago. Are these K&B engines the reed valve version? Sceptre Flight has the March 1961 Model Aircraft test report on the .049 Tornado version:
sceptreflight.com Model Engine Tests/K&B Tornado .049
It put out about the same power as the Cox Babe Bee, may be a touch more. With a 22% increase in engine displacement, it would be understandable why the upsize with a heavier plane.
OK Cub when they came out with their reed valve, upsized it to .059 (.06). From what I heard, it produced decent power comparable to the Cox Babe Bee.
Leroy Cox was able to produce his reed valve .049's cheaper with better quality than the others, and by the mid 1960's the competition discontinued their efforts as they couldn't compete. Wen Mac later Testors continue selling their .049's, and Herkimer their OK Cubs.
In 1973, I ordered an OS Pet .06 for more power in my Goldberg 1/2-A Junior Falcon on single channel, but the now defunct Hobby Shack substituted an OS Max .10R/C cross scavenge at no additional cost, a sweet deal. (Sorry for departing off topic.) - George
