ok, i have some experience using flaperons (mixed with elev).... it works well, the only downside being a little mushy controls on landings

i wanted to use this type of a setup on my DF jet for obvious reasons (to slow it down on landings) BUT then i read a post about using spoilerons -being much better for landing a jet...... it seems that the jet lands much better in a "nose high" attitude due to the spoilerons (up 10 deg) and they slow the plane down....

can anyone explain to me why decreasing the wing lift would help landing the jet?

if someone uses this type of a setup pls let me know

thanks, Vasek
BTW am still searching for a set of plans for my BVM Ultra Viper... anyone?
