I just finished the test on the K&B engine and it went well. It held a steady 10200 rpm and was a little rich with an 11x4 APC prop. It got one minute 15 seconds per ounce of fuel which should give me enough to do the entire AMA pattern. I'll have to bring it along next time I fly the Twister.
There is some method to my engine swapping madness. 40 size engines can use .015 size lines. Larger engines need .018 lines. This creates extra work to fly the different size engines on the same outing. I only have two planes with bigger than .40 engines, the Ringmaster 576 and the P-51. I can take those together and use the same lines thereby saving time and energy. Oh puke, I think I'm going "Green". I'll burn a tire today to make up for it.
