Regarding the magnetic downforce issue we discovered yesterday –
While almost all of us went over, it seems like there is still a fairly wide variance with going over. Correct me if I’m wrong, but I remember the highest being in the high 40s or maybe even low 50s? Mine was at 31 and John’s was the only one within the standard limit of 30. 20 more grams of magnetic downforce seems to be quite an advantage to me, even if I am relatively new to this. I don’t really see it as being reasonable to ask everyone with magnetically hot motors to buy replacements until they find one that’s within the limit. Equally, I don’t see it being reasonable for people that end up with motors with lower magnetic downforce to buy several until they get one comparable to the higher numbers. That seems counter to the spirit of a spec series. Is it sacrilegious for me to suggest we up the limit to reflect the maximum we saw with a stock motor and allow those with lower numbers to run magnets to match that downforce? There’s lots of teeny tiny magnets available to fine tune it. I learned the art of this in Houston.
