weight is now 410 gram for the complete airframe
Phil, unless your airframe weight includes the two servos its a bit porky. Mine is 380 grams including the servos.
But the rest of my hardware is heavier than yours, what battery are you using? Mine is only a 30C 2100 3S-1P Kokam but it weighs 210 gram.
Perhaps, just like me, it put on weight over Christmas.
