In my gtst, i have hit the limiter several times since i have owned it, with a regular power fc.
A few things i have noticed.
1. Its not accurate, as others have noted, i have my limit set at 6900, and i have seen ~7100 as peak rpm
2. It has NEVER showed a higher than normal ping reading after hitting the limiter, my ping readings are very low, usually around 10.
3. The only odd thing i have noticed when hitting the limiter is plenty of popping(rich pops) and i dont understand how that happens when there is meant to be no fuel.
(i dont know what my afrs are, i need a retune its very rich)
