Can anyone help please ? I have built the Blackhorse ARTF Gladiator but I am concerned as to the C of G position. The instructions are very basic and shows the C of G as 10 to 11 mm back from the leading edge. This seems very far forward to me, normally I would have expected the C of G to be about 1/3 of the chord back. - If there is a miss print in the instructions and it should say 10 - 11 cm then that would put it where I would expect it to be. Thanks Paul
