Quoted from nicoy3k:
Does your right flipper fade much faster than your left flipper? I’m wondering if there is an issue with it... just had a decently long game, three songs two all the way to applause jackpot and by the end of it making the left ramp was 50-50. The left flipper seems to keep its power no problem.
In testing the right flipper gets hotter than the left as it's used more. It's especially an issue if you have one of the builds with the larger FL-11629 coils on the right flipper rather than the smaller, cooler FL-15411 (that still fades in GnR, but not as fast as it doesn't get as hot as fast). It seems like JJP has moved to FL-15411s on all three main flippers now, but there are still some out there with a single larger FL-11629 on the right (or strangely, just the upper right instead on at least one) that will get even hotter than the 15411s. You can tell what you have by looking at the numbers on the flipper coil wrappers. 15411s still fade, but they seem to top out about 40-50F less than the 11629s (unless you trap play a lot, in which case all bets are off). So still pretty bad, but not as bad.
In one of the non-cooled baseline temp tests Karl Deangelo (who traps a lot) had a temp of 219.8F on the right flipper. In the final long test, the Tibetan Breeze kit installed cut 100F off that temp and restored full power, but it was a struggle getting there. It required multiple tests with increasingly more powerful fans since the standard fan I use in the Spike and Spooky kits didn't have enough CFM to keep the coil below the fade zone. We stepped up from the standard fan to one with 20% more CFM to finally one with 50% more CFM to get to a point where the temps could be held below the fade zone with only maybe a quick spike into the bottom of it if there was a lot of trapping for a long time (we're talking like 20min straight). So the JJP kit will be different than all the other kits so far in that the fan is much more powerful because of the extreme temps the coils generate.
Here's a graph of the temps from those two tests on the right flipper. You can see that the uncooled right flipper was already at a crazy 195F after only about 30 minutes of play...
And here's one where all the jjPotC flippers were compared uncooled vs cooled that's pretty illustrative...
