1) I always use 25ms for PULSIN_MAX ...( add the pulse duration and it's Ok for all ! )

2) Ah, Futaba RXs !!!

Some care has to be taken for Futaba and Sanwa, some of their receivers output a ~ 3.5v high level ...

So, They will work with a TTL input, but not with a Schmitt trigger input ( as PortB.0 in interrupt mode i.e ...) : it will work with a PULSIN PORTB.0 , but not ON INTERRUPT (i.e.) ... that can offer happy debugging times !!!
