I think there's a lot of pilot error (lack of education) involved here.
a) I fly the anton 9s vs spitIX+25lbs (all '44) with reasonable difficulty and almost at full power = 50/50 outcome
b) Then again with the dora9 vs spitIX+25lbs (all '44) with little or no difficulty mostly at full power = 25/75 in my favour.
All scenarios < 1000m, never had and overheat... I mean not one ??
All Difficulty = Full Real
