Default RE: TAKING OFF WITH FLAPS

ORIGINAL: gofast53

Would it be fair to say that using flaps on take off (flaps down) would allow a model take off in less distance. Have just set up a GP Stick 60 with flaps and have only experimented using flaps on landing only, with a bit of wind I can land vertically from quite a height, the plane literally floats down!
On that model- quite effective - even down to almost 90 degrees!
The full scale comparisons are not very good because they have far less power - relatively and are very heavy -relatively
The little FunCub by Multiplex is a case in point - two small flap positions -about 20 degrees and about 85 degrees -
full throttle creates a extremely short take off and with no trim inputs a 75 degree fuselage attitude -
rolling flaps back to zero the model then requires a big dose of down elevator to pitch over to level flight.
On landings I use coupled flaps and elevator - (down elevator) - this allows for a very high sink rate which needs throttle app to prevent a pancake.
Flaps be fun!
PS the wheels are correct scale for the plane
