Yellowred,                      The manual is available on the "CML Distribution" web site in pdf format. If you have any problems locating please advise and I'll try and post a link.  Mine arrived with manual though I think the early kits had this missing hence the pdf.   The information is on page 24.  "Step 2"  inidcates C of G at 105mm to 115mm, yet diagram below this information shows C ogf G at 95mm to 105mm.   I have gone for  95mm, from L/E at  root.   I have modified / beefed up the retract mounts and installed oleos to help with what I think is the only weekness in a smart ARTF.  If I could get another cheaply I'd have another !

Yes, I too have completed and flown this Spitfire, but would advise caution. The first flight identified that the aileron control rods are too light a gauge and cause a concerning aileron flutter at medium speed. This was cured by mounting a seperate servo for each aileron. Similar problems were found with the rudder and elevator control rods which were also "Beefed" up. Being an intermediate flyer myself, I got the club instructor to fly mine, after he was satisfied he gave me the sticks. The Spitfire tends to nose over on take off / landing due to the position of the U/C, but flies well. It handles much different to a trainer and would advise experienced support until you get to grips. Happy landings.
