Retuned the engine for premium autogas. Surprised to find a considerable bump in power output over Avgas. The engine is pretty well broken in so the numbers I am getting now should be a bit better than a couple months back, but still this much was unexpected....

18x10 3 blade Mezjlik, 8150-8200 rpm at full revs, 7400 at mid throttle where I fly (Avgas ran about 7700)
20x10 MDK Hybrid, 7920-7950 rpm at full revs, 7150 at mid throttle where I fly (Avgas ran about 7400)

These are steady state numbers. The TNC tach also has a peak rpm feature; these were not peak numbers

Just received 19x12, 19x13, 20x12 and 20x13 Xoar electric wood blanks to be laminated into MDK Hybrids. I'll have numbers in due course.
