I have a Goldberg Ex-Treme 330 profile and want to set it up with spoilerons and flaperons. How many degrees up or down should I set up the spoilerons or flaperons to move with the elevator? That brings up another question. If I have a spoileron set up with up elevator, up ailerons, how about down elevator? Down ailerons then? I guess I am confused about the whole thing come to think of it. I need some advice. Thanks

OK.......First thing.......with that bird, spoilerons are not needed, so I can't imagine what would get you started in that direction! The only possible reason would be for slower, more stable landing......but with a little throttle management, that bird will already land at a crawl!!
You may be thinking that adding this feature will make your bird more maneuverable....NOT SO....it will only get you in trouble, and probably be the end of your bird!


But if you insist on trying this,(and I know you will) you setup the ailerons coupled to elevator. and both surfaces should be dialed UP about 10degrees to start with when you use elevator. You will have to adjust the amount of travel to suit your needs.......BUT I know you will see that this setup is not necessary!!!

Good luck........you're gonna need it[]!!

I've had a few of these planes. I always used flaperons, which move opposite of the elevator. This feature gave me better waterfalls and more pitch authority. I've never used spoilerons couple with the elevator, but I have used spoilerons (both ailerons deflect up) on a switch operating independantly. I used that most often for timed events in funflys, like take off, 3 loops 3 rolls landing. The spoilerons cause the airplane to descend rapidly with the nose high. You balance your descent with elevator and throttle, usually coming in on the power just before touchdown. With a bit of practice you can come in and land really fast.

If you decide to try flaperons, start conservatively, say, 30%. You'll find they actually smooth out elevator response. Interestingly, I've had some ships in which the nose would hunt a bit in harrier, pitching up and down just a bit as if there wasn't enough elevator authority on tap. Flaperons solved this. Lots of folks say you need spoilers to handle wing rock in harrier. I say they need to learn how to harrier. Practice will take care of wing rock. Anyway, there is nothing scary or on the edge about using flaperons. They yield a smooth, enhanced elevator response. If you're a bit nervous to try them, just dial in more expo than normal to start.

Good luck!

Thanks, I'm going to give this a try.

This guy has no idea what he is talkin about.

You talking to me??? Hmmmmmm lets see.......I 've been flying RC for about 35 years.....built, flown, tweaked almost every kind of bird that hit the market since 1972........Have been and still part of an RC club that has been in existance since the early 50's......held an office in that same club for more than 15 years..........and yes....I'm even a fellow ProBro for the last 2 years.......SO, I think I may know a little bit about tweeking a bird with spoilerons.................so back off georgee!!!!

I like about 50% on spoilerons rule of thumb and 30% on flapperons. I find spoilerons are much more forgiving than flapperons because you can have too much flap for a turn and end up snapping out. The spoilerons can be as much as you like, but I like to leave the last 50% of travel for aileron authority.

I use spoilerons a LOT in windy conditions as I find they really help me to keep the plane in front of me when I practice rollers (ie, TR's at an angle to the wind, so it looks stationary). They also help some of my planes KE spin easier.

I very seldom use flapperons unless I want to do very tight waterfalls.

I have both programmed into my JR 8103 "landing" switch -- up for spoilerons, neutral is off and down is flapperons.

I have one of these Goldberg's too and have not flown yet. What's the concensus on the neutral aileron positions? Level, slightly up (spoileron), or slightly down? From what I've been able to gather thus far, most are saying slightly up. Mine are set so that they are nearly straight with the bottom edge of the wing. Is that up too much?? Don't matter?

Jeff,
I like to keep mine neutral.

It's just that you acted like he was crazy for even asking about them. I have spoilerons and flaperons on every profile I have ever owned. I use spoilerons more than I do flaperons.

Its funny. Some profiles like flaperons and some don't. I design a lot of my own and I am currently flying to renditions of the same design, one for .46 and the other for 120. The 120 works well with the flaperons and they just seem to mess the 46 up. I always keep them on a switch so I can turn them off if I want.

I tried the flaperon thing and it made a big difference in takeoff and landing. I have a Futaba 9C so I dialed in 50% flaperon to elevator. I don't have much throw on the elevator on low rates, so 50% of the elevator movement doesn't move the ailerons too much, but boy what a nice difference. My takeoffs are more flat, since the airplane used to jump off the ground, and the landings are more flat in the flair. The nose used to pitch up a lot more. I LIKE IT! I am going to use this flapperon mode for my takeoffs and landings form now on I think. Next I will try the spoileron thing. Right now I am out of town for a week. And as an answer to a previous question, my ailerons are neutral to the chord of the wing. Maybe if they were neutral with the bottom of the wing, it would be like having flaperons on all the time.

Always set up my fun fly stuff with both flaperons [ ailerons move down when elevator moves up } and spoilerons [ ailerons move up when elevator moves up }.

A party piece manouvre with my Sledge is near vertical normal attitude descent with full up spoilerons finishing in a roll out landing if I get the throttle blip right.

WARNING KEEP THE AILERON MOVEMENT TO ABOUT 1/3 OF THE ELEVATOR MOVEMENT FOR YOUR FIRST ATTEMPTS AND FULLY EXPLORE THE FLIGHT ENVELOPE ESP. AT SLOW SPEEDS AND LOW THROTTLE SETTINGS.

Why because in some cases the ailerons can overpower the elevators giving control reversal on flaperons and very peculiar behaviour on spoilerons.
