RE: canard foreplane loading..??
Lnewqban,
your are quite right except that I did not deploy any flaps since that ship only had one single aileron on the main wing. Further as you can see I experimented with high and low placement of the foreplane but that did NOT help the "nosedropping". It all comes back to the very high foreplane loading with +3 degrees aoa. Of course you can reduce foreplane loading and its aoa and then fly the plane so fast that stalling is avoided. But then the speed envelope gets rather limited and the plane will become "divergent in pitch" and very tricky to fly provided you do NOT use elevons.
DAN,
nice canards you have there, it appears you prefer a low foreplane but do you also have elevons...???
So I would like to move towards more flaps and much less foreplane loading but
how far can you go in reducing foreplane loading in a canard model airplane..???
Modern fighter aircraft such as the swedish JAS 39 Gripen, the Sukhoi SU 47 or the X-29 probably have very little if any loading at all on the foreplane but they have powerful computers onboard and elevons to achieve pitch control....Cheers/Harald
