Runs real fast and stable. set up is pretty much right on in the plans that come with it. i put the glowplug just behind the cg, easier access to the carb. then i added 2 pounds to the nose. right in front of the radio box. my flap are adjustable via third channel. i run a picco 67 exr w/muck pipe at 11.5 from the glow plug and a s 250/s 255 prop depending on the length of the straghts. i got this in 94 and finaly finished it this year. thanks for looking John
