hello, I have broken the fuselage of my rrd !! right where the front wing ends. Since I can't get the spare parts for a new fuselage, I used the same fuselage and made the booms and threads for a new wing. But now the new wing was much closer to the mast, approximately 10cm. The front wing is no longer equidistant between the footspraps position. Today I tested it in the water and it became totally unstable longitudinally and all foot behind !! The mast foot brings it back to its maximum point. The 330cm stabilizer points it almost 1cm down. Is there anything else that can be done? Thank you

pictures would help, and that foil has a long fuselage, like 115 cm, right?

Are you using a two bolt or one bolt mast base? If your are using a two bolt, try a one bolt. But not sure if you can make up 10 cm.

Probably need to get a new fuselage, sorry to hear. How did you break it?
