Thanks guys, I'm doing the R/W instrument first because I need the hours for instruction purposes and I don't want to delay my helicopter training. I'm trying to continue that and stay proficient in that as that's the most important to me since it's what I want to do for a career. The F/W will be for fun and maybe part time work if I feel like it.
I'm at Quantum Helicopters in Chandler, Arizona and I'm doing all my training there part 141. It shouldn't be a problem doing my F/W instrument add-on part 61 should it?
