Default RE: Sebart's new pattern ship MYTHOS

Had a few flights on my Mythos 125 now, running 8S 5000 packs with Hacker A60-5S
My main concern is the pull to canopy in KE - both sides. This is usualy indicative of too forward a CG but I've put the CG as far back as I can (about the rearmost position - 225mm from LE) & it still shows. Can't go any further back as my motor is over 100g heavier than the XS motor plus my batteries are heavier (vs. a 6S set-up).
I have replaced the APCe prop & sebart spinner with a PT 20x12 & Falcon carbon spinner saving 85g, even with with the batteries as far back as they can go I need a 10% R-E mix to rid the KE canopy pull which is more than I would wish. I'm carying only slight up elevator trim (2 clicks).
I have not fitted the wing fences or UC fairings, Rudder servo is in the tail.
So what have other Mythos 125 flyers ended up with reagarding CG & the need for KE mixing, thanks.
