i just got in to the sport so i'm still kinda green but think i'm a pretty good builder. so a friend of my has trusted me to put his old plane he had crashed a long time ago it had set up so long the fairly new os .40 he had on it was locked up even the carburater was locked up. I noticed that it did not have any ailerons just wondering how good it and really if it would fly with out them he said he only flew it twice crashed both times but he had never flew one before so i don't now if it was him or the lack of ailerons don't now what kind of plane it is but it looks like about a 60 in flat bottom wing trainer any coments or words of wisdom apreciated

i might venture to guess it is a sig kadet,a well known trainer that only uses rudder,elevator,and throttle,they fly well,a little different than an aileron trainer but still well.just remember that it will take a tiny bit longer to make the turn,the tail of the plane will slide through the turn almost like the plane is sliding,i would not be afraid at of of trying the plane out,check it well,make sure nothing has come loose,put some fuel down in the carb and lossen up the engine,you might be quite pleased with the plane

got the moter going after a good taking apart and cleaning up it fired right up was just wondering if it would have a problem of rolling over on its side and not being able to straighten it back out with out havein the ailerrons to trim with
bill

the airfoil on this plane,should have a lot of dihedral,the rudder will be very responsive in flight you should not have any trouble,i have barrel rolled kadets with ease they have the ability to self right themselves for the most part,when you fly it take it up a good ways then bank it on its side and bring the stick back to center,watch how the plane corrects the maneuver,you will be quite pleased

it does have lots of dihedral i was going to put ailerons on it when put it back to gether but now i think i will just leave it like that my plane a falcon three has ailerons and you need them
i use them to turn in stead of the rudder haven't even tried to do it with the rudder unless i was on the ground thank you for the in put bill

Punctuation - learn to use it.

When setting up planes with no ailerons, some folks plug the rudder in to the aileron jack on the receiver.

If you are used to flying using only the ailerons and elevator, hooking up the rudder this way will allow you to fly the plane with out re-learning your reflexes.

It can cause problems with take off and landing depending on how your nosewheel or tailwheel is set up.

There's no problem with flying with no ailerons. BUT you need that excess dihedral to provide the roll couple when the rudder yaws the craft. Without it all you get is a skewed turn and trouble.

Thousands of rudder, elevator and polyhedral gliders can't be wrong.

Years ago I had a polyhedral glider that I put a Max 10 engine onto. With the strong yawing effect of the oversized rudder and the ample dihedral it would actually do very nice axial rolls all the way around and even flew inverted (poorly thanks to the strongly lifting airfoil but it did fly). It was an odd looking roll. Very axial but with the model cocked off at an odd yaw angle the whole way around. In all these modes of flight the rudder responded just like ailerons.

As for your Kadet you may find that if you DO put ailerons onto the wing it may not respond as well as you think. I've heard a few reports of strongly dihedraled wings that ignored aileron input for some reason. If you do try them without flatenning the wing then it may help if you use a lot of differential movement.

Hope this helps out.

It always amazed me to watch people fly without ailerons. It is skill many people never use but is good to learn. I would recommend that you practice without ailerons and then go from there.

I would second Montague's recommendation and plug the rudder into the aileron jack on the receiver. That way you're still ysing the left stick to turn with.

Was that a typo or are you flying the alternative mode 1 with the airlerons where the rest of us have the rudder?

I have a Seniorita Cadet- about 10 years old -with a KB 20- -weight under 4 lbs.
The radio is setup with mixed rudder /aileron.
The Tx is setup with expo/dual rates for very forgiving OR high response.
I fly it -or teach anyone to fly it as if it had ailerons-
Also -I often hold a "free flite " trim -shut off the TX and let the model fly it's self. (PCM radio).
The student can then observe the relationship of power /elevator trim setting.
The plane settles into a diving -stalling then recovering mode- if the power/trim is wrong.
This may seem a bit old fashioned -but if the guy "gets" what is happening - he quickly adapts that understanding to learning the basics of flying/landing speed relationships.
If student choses mode one or two or three - makes no real difference- either stick provides a turn- included stick movements tighten turns- opposed stick movements - loosen turns.
All in all the best trainer I have ever used .
Also the flying speed can be held to as low as about 20 mph with decent control

Welcome to a fabulous sport.
I'll make this one short and sweet. I have built several plane with no ailerons, with no real difficulty in handling.
The main thing to remember is to have some dihedral- key here being some. 3 to 5 degrees is more than enough.
I have even built a couple of low wingers with only rudder and elevator. As long as the middle of the "V" the wing makes is around the center of thrust,you'll be O.K.

E-mail me if you would like to talk about this or other model subjects in depth. I design and build full size planes as well as models, and I'm still here to talk about it!

please, NO, NO and NO !!!!

it is WRONG to think that you turn with the ailerons, you bank with them, and that's it !

using properly the rudder is a skill that too many lacks, and flying a rudder only plane as a beginner is a good thing, IF YOU NEVER FORGET WHAT YOU LEARNED......

As an aside, little story.....Some weeks ago, I took off with my old trusted super sporster .40, with a strong OS .70 surpass in the nose.. this thing move.... first turn after take off, I realised I had no ailerons......well, throttled back, and brought it back for a pretty correct landing with rudder only ( not much dihedral, but just enough). Very happy that I never plugged my rudder as said !
BTW, that was all due to my stupidity and precipitation, I simply had not plugged the ailerons properly....
