I just wonder how many flights Frank in Texas gets in every week to need the kind of spare parts he is running short of, ya' know? (I just pick on you Frank because you said that you are having a hard time finding parts for the SF.)
I also run an SF ABC now and it runs like the wind. I am looking forward to the same great service from it that i have been getting for all of these years from my OS engines.
Like the Super Tigre V60 that I ran in C/L Stunt for 25 years, the OS in R/C seems to be my "go to" unit.
My son just got two 46FX engines in two little CG Cap and Extra models, we'll see how it goes with these maligned engines next!
