FT Spitfire CoG - Centre of Gravity

[doctorrog]

Anyone got a spec for CoG/ Centre of Gravity on the FT Spit? I could not find one on the plan. Did maiden it with a 2200 stock but she kinda flew like a ski jumper. Suspect coz in uk we have to use 5mm she is tail heavy as there is 20% more weight. Interested to know what stock CoG is tho so I can match that with weights as necessary. Can get there myself in the end but want to know. Tks,

The center of the spar should get you close. May as well fly a bigger battery if you have to add nose weight. Good luck, the FT Spit flies fantastic!
