swashplate movement..how much is 2 much?

[929freak]

ok just got done building my 600 pro....was fine in flight during my break in tanks,very happy. but aon of the guys noticed me move my cyclic around on the bench and said I have too much movement and that I need to either reduce my percentages in the ccpm mix menu or lower mt aileron and elevater d/r's...
is this correct,and how do you know how much movement there should be?


600pro
os50 hyper
3 jr 8717 on cyclic
1 jr 8717 on throttle
jr 7703d gyro w/ 8900g servo
align gov
DX7
swash mix's at 60%
d/r's at 100%

Adjust swash mixs up until something binds, then back off a little.

[heliMark]

on a dx7 60's in the swash aft should be on par, again ensure that there is no binding, specifically at the extremes, with full collective and on top of that elevator and aileron in both directions and then with full negative collective. if the swash isn't hitting and the links aren't binding and the servo's aren't making angry noises you should be ok, when in doubt back off a few points :thumbup:

[929freak]

ok both answers make sense...thank you ...I also think some of the concern was that I am a new pilot
and they didn't want me getting into trouuble..i.e.having that much aggressive of a setup.so for now till I'm
a little more experiened I will just use the aileron and elevator d/r's to tame it down a bit.Does that make sense??

[Forced_Induction]

Check your ail/elev deflections and set them around 6-7°, and 11° positive and negative collective and youll have a pretty good setup for a new pilot.

[929freak]

so by 6-7 degrees of deflection you mean actual swashplate angle relative to the top bearing,or
basically from my level swash at mid stick?? just checkin'...... and as far as pitch...
N= -5 +11
S1= -13 +13
S2= -13 +13
TH= -13 +14

thanks for the help

6-7dergees blade pitch.

[LoveMyTrex]

nice setup there with 8717s. on the throttle it is a little bit overkill isn't it :YeaBaby: that is a badass 3D setup thought.

[Forced_Induction]

degrees blade pitch. it would be a bit difficult to measure swashplate angle :). also, i believe that having different pitch settings in different flight modes just adds the potential for problems, especially in TH. i use +-12° in all flight modes. why would you only need -5° in normal mode or an extra degree in TH anyway?

[Forced_Induction]

also the 6-7° is blade pitch change with max cyclic inputs on either aileron or elevator.

[929freak]

ok feeling a little dumb....I know how to do my pitches in relation to mid stick,low stick etc...
but can someone explain how to measure the "deflection" as someone put it...? or how do I measure
the swashplate movement ....so I know if I have enough or too much

[dna001]

Put your stick on the dx7 to max Negative, now move aile elev stick to all 4 corners...dose you swashplate hit the top bearing block. If it dose you can turn down pitch in swash mix, If you want to.

[wrex]

i ended up having to back off all the way to 48% so i did not have any binding.

[Forced_Induction]

set up your swash values so that you can get max like dna001 said. then lower your low rates to make it a bit less touchy. move the collective stick so that your blades are at 0°. then put your pitch guage on and holding the flybar, measure the difference between no cyclic inputs and max input. you have to measure with the main blades either parallel with the boom or perpendicular to it, not at angles. lower the low rates until you have 6 or 7° change up and down. make sure the flybar is level when you take the measurements.

[sparky]

I dont know of too many people that use more than -4 to a -5 in normal. You can really slam one into the ground in a wind! I agree with all your settings except for throttle hold. But as a newbi, you should be around +-11 to 11.5 until you start learning colective management. Then go to 14. It takes less stick movement to do the same tricks. Thus reducing the chance to dumb thumb a trick from going to the right or left on full defection of pitch or elevater.

Just my 2 cents.

[929freak]

hey its cool..all opinions are welcome,you never know your two cents could save me hundreds!!

[929freak]

forced..your explanation is what I was looking for,I remember someone explaining that to me when I first
started messing w/ helis......just couldn't remember how they said to do it!! I'll get on that as soon
as I get to the field today... thanks again

[Forced_Induction]

I dont like setting things up so they look good or to get the max. i like to know what the angles are. i just finished going through the head again and ive got exactly +-12° collective, 9° high rates on cyclic and 7° low rates. also, if you get a bit of binding in the corners of the cyclic stick (all the way forward right, forward left, ect) at full negative pitch, dont worry about it. youll pretty much never hit that flying, and if you measured the blade pitch at the proper angle, it would read a couple degrees more anyways. its not a big deal.
