Hi all
I've got the Seagull Zero with OS 120 fs up front, still had to add weight to the mount. Ballanced mine as instructions and flies fine. Replaced retracts with E-flite electric (plug and play) works first time, also sprayed mine with a matt lacquer well worth the effort. A few small niggles with the kit, use pull pull on the rudder pushrod naff. Tail plane farings, had two left hand ones had to modify to fit. Also as stated fire wall to prop driver incorrect.
Apart from the above it flyes like a dream and looks the part in the air. Allways getting comments how good it looks and sounds.
