My brother launched an AT J420R at whitakers last weekend for his cert flight.
When he took the casing apart to clean it post flight he noticed the plastic liner that the fuel grains go into had split lengthwise the full length of the liner.
When cleaning the case he noticed that it had pitted along where the liner had split...
So is the case no longer trustworthy? Are there any signs that cases have about had it..?
I'm liking the redline motors and find myself launching many of them with many more in reserve, they seem to burn hotter and i'm already noticing a little discoloration on the inside of my hardware at the ends of the casings from them..
Any opinions..?
