I have a sport plane that lands pretty hot. It has two aileron servos and does flaperons, but I haven't landed with them yet because I'm scared it will make the plane tip stall. Will dropping the flaps for landing increase the chance of a tip stall?

I have a modified Global Right flyer with dual ailerons, 25 degree flap capability.

Today wind was very low.....so I used flaps to land.....worked great.

Only thing I had to to was reduce the amount of down elevator trim that kicks in when I drop the flaps. Other than that it work really great, no evidence of tip stall.

Give it a try.

I haven't gotten a computer radio yet but one's on order. I would quess that you could set-up a mix so that when you drop flaperons your radio automatically moves the trim on the elevator to maintain level flight. I may be wrong so what do you other guys think?

:D Wreckman you are correct. As I posted previously that was the only adjustment I had to make.

You have to test fly, and make corrections, until when you drop the flaps the elevator puts the correct amount of down trim to keep the aircraft level. It takes several flights until you get it tweeked in. I did notice that the speed of the aircraft makes a difference in how much up pitch you have to correct.

I'm trying now to use the flaps at about the same speed each time.

Fun to experiment with.

Hi Toucan,
Deploying flaps will actually reduce the tendancy to tip stall and will help slow the plane as well. As stated above... when deployed the plane will pitch nose up. But it sure will help tame a rocket ship long enough to get it back to mother earth in one piece! :D

You might be able to get more precise info if you tell us which plane you have.......:D

I've had 30degree flaps programmed in for my SE since the first day I flew it but I'm still a little scared to deploy them.

Do you need extra power on w/ flaps to bring it in to the field or do you fly your normal landing leg using the same thottle setting that you would w/o flaps???:confused:

I never really got an answer to my question but I managed to figuire it out. With flaperons dropped to the flap positon, the tip of the wing is effectively washed in. This, in my experience, increases the possibility of one wing tip stalling.

Aircooper - are they flaps or flaperons? My UltraStick has flaps that drop 30degrees and I approach at 1/3 throttle with some down elevator.

Fatsky - it is truly a 'franken-plane' with the fuselage I scratchbuilt and the wing from a Hobbico.

One of my favorite mixes is flaperons to the throttle...
This is how it works and works great. set your flaperons to be deployed at preffered angle at low throttle stick position. using a multi-point mix you can have them removed proportionaly @ about 1/3 or 1/4 throttle.......The beauty of it is when your flying, go to idle gradually to setup final for landing, if you need a little bit more to stretch it out as you advance the throttle slightly, you also remove some flap deployment as well, getting more speed less drag, makes for full proof landings with flaps.

toucan...if the wing has strip ailerons - go for it.
If it has barn-door ailerons (like a cub) that is when you will create wash-in and invite tip stalls....don't go there!

A couple of things to watch for....make sure both ailerons deflect the same amount. Some control linkages, and even the flaperon mixing within the Tx can favor one surface over the other - resulting in a rolling tendency and with very little aileron control. Try it at altitude first.

As well, you will notice a pitching tendency often it is nose up, but depending on the configuration, could be nose down. Again prepare for this way up high, and determine how much trim you need. On most radios, you can mix flap-elevator to trim any pitch change. this will take some trial and error....

Have fun with it....:D

I have a modified Superstar .40 and with a t6xas and and extra servo I made flapperons. Ive had to bring mine in dead stick on short runways. I'd be repairing mine about 6 times without flapperons. they Slow you down but still alow for control at slow speeds. Slower for when you come in w/short runway and no engine!!! Alot of experienced flyers say that "beginners just want all the bells and whistles" but they're not the ones repairing or replacing you plane slash gear!!!!!!

ok, i have a auperstar .40 trainer.. id love to put flaps on that bad boy.. is it hard? how to do it?? also.. what are good winds to fly in? i live in toledo ohio and tends to be a bit windy.. usualy around 5 - 10 MPH average and 15 mph gusts.. too much for easy flying?? what is the limit on mph i should take my plane out? also, any landing advise? ive been flying REALFLIGHT sim alot l8ly and kinda learned the techniq of the landing pattern deal, but when ever i kill the throttle on landing, i nose up and then dive.. which makes me apply throttle and go for another pass.. i try about 5 times before i can get it. thanks!

I have flown my Super Star 40 in winds of 18 mph and more but it's not good for a beginner because the wind can easily throw that thing around. As for flaps, the Super Star surely does not need flaps. If you want to use flaperons simply add a 2nd aileron servo and use a computer radio but it doesn't need them. I fly at the shortest runway in Indy and I can land it easily. If you can't land it on a short runway then you should practice your slow flight instead of trying to overcome it by adding flaps.

Hi, Beginner here...

Was wanting to add to the questions here. How exactly does the flaperons work? I mean I know that it allows you to independantly move the alerons so you can slow the plane down like flaps. When this happes I assume the two alerons move in the same direction like flaps. So then how do you control your landing without dipping one wing or the other into the ground? Does the flaperon computer still allow you to move the alerons slightly independently in that mode so you can control the plane?

Yes, flaperons means that you are giving the ailerons two functions; as ailerons and as flaps. When you setup flaperons both ailerons go down to act as flaps but at the same time you are losing some aileron throw as well. Too much flaps and you don't have any aileron throw. In order for this to work you need a computer radio that can do flaperons and you need a servo on each aileron.

Yes, it probably has a lot to do with which plane it is. I have my Sig SE and Sig Fazer and 8U transmitter programmed so I can deploy either both ailerons up or down, when I go to up it really puts the brakes on and drops the plane down quickly but when I use down, the plane really wants to float although with the flaps down it really gets off the ground in a hurry, I have about 25 or 30 degrees programmed in and I do have to use some up or down elevator to offset the brakes or flaps.

Ok you guys have just convinsed me it will be well worth the pain and suffering of a loooooooooooooong drive to get to my nearest club so I can get some help setting up my kwik fly 60 wich has a centre flap,my radio is a jr2610 and has the ability to convert ailerons into a flap function,sounds simple enough but programing it is still a bit of a mine field to me, so in that case will remove "Y" lead from ailerons and take to club so can get some help, With the thunder tiger pro 61 engine fitted it is quite a heavey little unit, so using the aileron function as described above it should enable a better and shorter take off?I hope
does what i have just sumised make sence or am i barking up the wrong tree.
