My new FS3 arrived yesterday after making its long journey over from TUD ModellTechnik. This is an F3F version. One of only a few in the U.S. (As I understand it, most of the FS3's are F3B versions. ) It's a double carbon 2300g. "De Luxe" version. A BIG thanks to my friend Dave Olson for coordinating the order and personally delivering the model to me here in Portland. Dave you're awesome! This one has LDS with some noted improvements over the LDS system in my FS4. I plan to install JR HV servos in it. Cheers!
