Hector  ,  what is the servo`s you have put for the flaps ?
i will fit on my elevators 2 Hitec 5595 (25kg) its will working good?
do you mixed only the flaps with the elevator for the landing and take off ? without the aleirons ? can you let us know the flaps should be down in (cm) with the mix of the elevator up in (cm) if you can determine that with the ruler :-)
