Hi all, i bought an old nieuport 17 model at an auction and decided to try and get it flying. i had to strip some old covering off and as a temporary measure i replaced it with what i had laying around until i get it flying properly. in the meantime would anyone know where the C of G is on a model like this? its about 1.1m wide, just under 1m long and is fitted with an electric motor, similar to a ripmax quantum 2 .40 equivalent. I tried a 14.4 4 cell battery but this seem too large and heavy so i was going to try an 11 volt 3 cell instead.

would the C of G be a point between the ends of the main spar but in the center of the wing? which would put it at a point near the back of the wing above the cockpit. it does have a sweep on the main wing.

my flair example balances just in front of the rear strut for the top wing and isnt that fussy as i experimented with various levels of ballast and it didnt seem to make any difference at all

On the Radio Modeller Plan version, RM149, designed by my old Clubmate Eric Robinson, the CG is about 75% of the shortest point on the upper wing centre chord.

The semi-circular central cut-out on the trailing edge of the wing means it would be about 60% of the chord if there was no cut-out & also corresponds to the leading edge of the lower plane.

Thanks guys, great information. This is actually further back than i thought. Leading edge of the lower wing will be the starting point then.

Thanks for your help.
