Fuselage length
Posted: Tue Feb 13, 2018 7:00 pm
I have noticed that generation 1 racefoils eg Sword 1 had a few cm distance between the front wing and the fuselage, gen 2 eg. Sword 2 reduced this distance. I think this was done to reduce torsional effects of the front wing relative to the mast. The latest generation racefoils seem to have gone to a middle ground with a bit more distance between the front wing and mast again. I'm thinking this may improve pitch stability when pushed hard (not sure about this). Fues seem to have got little beefier also.
I have an older gen 2 carbon foil and as I like to tinker I was thinking of extending the front fuse a couple of cm to maybe increase the pitch stability. It would take a bit of beefing up of the fuse to reduce the torsion in the fuse. Has anyone tinkered with this in the past and has any comments on performance gains/losses? I would be keeping the AOA of the front wing the same as before.
cheers
