Exceading recomended control throws?
 

I was looking to get my Dazzler to perform more wildly, and decided to put the control rods all the way down on the surfaces.

Then I thought about the recomended throws. I don't mind having the rudder and aileron thorws larger then the recomended ones, but what about the elevator? I don't want to give full up and have the wing fold nicly into the fuse....

The recomended throws on the elev are 19 mm (high). Right now I have them at around 25-32mm (I've not got a throw mesuring tool, so I used a triangle). Would that be OK?

Thanks,

I dontthink that will cause you any problems. I usually try to get all the control throw i can get without binding.

If the wing folds up you were either flying to fast or the plane had structural problems.

I say go for it!!

The Dazzler wing should be able to handle it no problem. As long as you put it together properly, I think you'd have to worry about the wing coming unglued from the fuse before that wing will fold...

Get it propped for thrust not speed. If it's a 46 throw a 12.25x3.75 or a 12x4 on it. Don't try whacking full anything at full throttle until after you get a feel for the response at 1/2 throttle. If moving the clevises in gives 45 degrees or so throw in a load of expo for your first flights.

Thanks for the replies, guys.

I'm using an APC 12 x 4.
The serfice is definatly below 45 degrees.
I forgot to mention what I did:
Before, I had all the rods at the outer-most hole. I mesured the max throws (100% Duel rates, 100% servo throw), then put the rods in the inner-most holes, and set low rates for the old throws (around 48% D/R). Now high rates are nearly the full throw (100% D/R).

I was thinking about it, and remembered that most 3D pilots use 2 rates: normal rates, and 3D rates. That is, at normal flying speeds, they have the low, or flying, rates on. Once they go slow, they flip it over to 3D rates, to get more control at low speeds. Maybe I'll do that: Takeoff, flight and landings at low rates (which are basiclly the high rates of before), and when I try to do 3D stuff very slow, I'll simply flip over to "3D rates".

What do you think?

Thanks,

The only thing I'd suggest is that you're better off getting more throw by putting longer arms on the servo. Moving to the inner holes at the surface horns can make the surface more prone to flutter.

The rods ARE on the outer-most hole on the servo arm...

RE: Exceading recomended control throws?
 

Right but you can get longer horns at your local hobby shop or on line.
the longer horns are stronger and by going longer instead of closer to the surface you maintain mecanical advantage to the surface. am i making sence?
Plus, it sounds like you have a computer radio, use your atv (futaba) or whatever your radio calls the travel adjuster and crank the % to as high as it will go, or to as high as you can without binding servos, this gives you more resolution and lets your servo travel to it's potential.

I'm not trying to get more throw out of my serfaces, I just want to know if is it OK to give full up elevator with full throw.

RE: Exceading recomended control throws?
 

Recommended throws? We don't need no stinking recommended throws!

I use lots of throw and some expo.

Best answer yet...Tell it like it is Billy!!!:D

RE: Exceading recomended control throws?
 

To answer your question directly, yes it's OK. Most of these things will handle more g's than you can throw at them, however everything has a cycle life so eventually after many high g loadings it will fail. Somewhere in here someone posted some actual load tests of wings. Do a search the results are interesting.

when i set up a plane I get as much throw as I can out of it . then i use the radio D/R to set it to the recomened maximum throws... thats my low rates :D

then i add anywhere from 50-80% expo to the high rate.. first flight is on "low rates" then i try it on high... once i get used to it I usually dont use low rates anymore. but thats just me [sm=bananahead.gif]

RE: Exceading recomended control throws?
 

To tell the truth I have actually been backing my throws down a little. I found I'm getting better inverted flat spins with less throw. But throw is like the throttle, you don't have to use it all, but it's nice to have them there when you need them.
SIDE NOTE - I take off and land on full rates. I don't see the point in not having full control when I'm inches off the ground.

RE: Exceading recomended control throws?
 

Thanks for all the replies, guys.

I think I'll stick with my initial decision to have full rates at high rates at low speeds, and low rates at high speeds.

Thanks!
