OS GT22 fitted with stock OS 'Pitts' silencer.
50:1 full synthetic fuel, has had many hours of flying so well run in.

Weather very hot, 25C?

APC 16x8 - APC 17x6 Pattern - Menz 17x6 = all approx 8,500rpm.
Menz has noticably less thrust and surprisingly noisy.

APC 17x8N = 7,800rpm - preferred choice.
