RE: What About a Staudacher S-300?
I have a lanier staudacher slightly modified (raised the wing 1 inch and airfoiled the stab and fin). It flies great. Managed to win Sportsman (NC Regional champ) back in 2003. Still have it and need to sell it to make room for new stuff. It's in the 3D and aerobatic classifieds. Good shape, just normal usage rash. One hell of a bargain. All you need is radio and engine. Includes all digital servos and BUILT IN home made cannister mufflers (very effective).
It took a long time to figure out how to make it "present" well in the snaps, but once I got that figured out, it was a fine flying machine. This one comes in at 27 pounds with a BME 102/105 on it. It doesn't fly heavy at all, and is VERY stable. It's a good low cost entry into IMAC. I would recommend it as a first IMAC airplane if you're on a budget.
