INSTALLING PERMENANT ANGLED FLAPS

[Crstn_Jdi]

I know this is an oddball question and/or idea, but I was wondering if I added flaps that were permament(sp) deployed [ just glued the sections at an angle without servos or any hardware ] for permament speed control for slow speed handling/landing and reduces top end speed, if there is a need to compensate for them in programming the elevator for this modification? Anything bad from this?

It's likely you'll need to add a small amount of down elevator, or even a mix of down elevator with throttle.

My Volantex Phoenix 2400 glider requires up trim for Gliding with flaps for super slow flying, but requires down elevator mixed with throttle for gaining altitude if the flaps are down. I have mixes on my flight mode and flaps switches to adjust for the type of flying I wish to do.

...is a need to compensate for them in programming the elevator for this modification?...

Some trim adjustment, probably yes. Programing, as long as you fly slow probably no, but you may need a throttle > elevator mix, as airforge suggest, when you decide to fly faster.

With flaps, its ALWASY good practice to try them a few mistakes high. You never know what is going to happen the first time you deploy them. You want to be a few hundred feet in the air to give you time to react to whatever happens. If the plane dives when you have some altitude, it's no big deal. If you are on landing approach, 10 feet off the ground, it's a bad day.

You might want to consider also adding slats, essentially flaps on the leading edge of the wing. Full size passenger planes use both slats & flaps at the same time.

True, but I'm not gonna fly fast/full throttle for I'm flying in a somewhat small or just barely able to fly in field. ^_^.
Thank you for the input.
