Hope devs will address this soon - brfotr the beta patch I seemed to be able to avoid the worst of the 109 mixture/bumping issues through what I thought was patient warm up and restiction of revs - managed a climb to 7400 no bumps on syndicate server (full CEM and temps) - but now I get it as soon as I get up nearly, no matter what I do unless I go full throttle - then it's only a matter of time - even with managing rpm via prop pitch before it goes pop - even with rads full open and temps seemingly ok
