What would be a normal pitch and power curve for hover training and beginning flight. I have a 5 point curve. I don't seem to find any help in the instructions except for SWASH settings of
-65A, -65E and +65P.

BTW what would these swash settings give me anyway, mild, medium or hot.

Thanks, Mike.

It does mention it in the instruction manual.
As far as proper pitches. You will get different opinions.
Me: I set mine up to hover at 0% collective -1, 50%
collective +6, 100% collective +9 .

You can set the pitches through the swash pitch setting or by
the 5 point pitch curve setting.

Thanks Randy. I understand how to to set the 5 point pitch curve to get what I want(thanks for the degree help), but I don't understand how the SWASH pitch value works.

The manual recommends +65. What does that mean? It it just a number that represents how much total movement you get in pitch?

I don't see how that would allow me to get specific degree values like the curve. Should I use both, or set the curve to what I want and max out the SWASH?

My Futaba 8U radio manual does not mention about how they affect each other, it just says how to set them with little insight about their use.

Thanks, Mike.

That quote is correct. With that being said. lets say you
lowered the +65 swash pitch setting to +50. This would
give you a over all softer pitch.

Example: +65 swash setting might give you -4 +8 +11
from low collective to full collective. +50 swash setting might
give you -1 +5 +8 from low collective to full collective.
This is leaving the pitch curve at default 0 25 50 75 100.

Just use the 5 point pitch curve. You know how to do that.

Randy, just thought I'd let you know she flies great. I used the pitch curve you gave me and a throttle curve of 5,20,40,60,80.

She lifted straight up with almost no trim required. Very sensitive cyclic! I think I will need to push the Ail,Ele SWASH settings even closer to the bottom until I get her tamed.

Thanks for the help.

Mike.

Thanks: GOOD JOB !!!!.
Enjoy that caliber she is a good ship.
You did it not me LOL. All praise goes to you.
Have lots of fun with your new found toy.
Remote hellis is a lot of fun.

you should be using dual rates for taming ele,ail,rud control

you should be using pitch curve to change Pit control.

SWASH AFR is the EMS equivalent of MMS ENDPOINT.

Although you still need to setup the endpoints at their physical limits using the endpoint menu, this only changes the particular servos endpoint, eg ch6 is pitch.

BUT, when using EMS, ch 6 does not solely control pitch, all three servos do, this is why SWASH AFR is only used on EMS.

I NEVER change the SWASH AFR settings from what the manual states.

The problem everyone seems to forget is that when you advance to forward flight or require an IDLE UP that gives more cyclic or pitch, you cannot achieve this by changing the SWASH AFR settings with the IDLE UP switch.

This is why we have pitch curves and dual rates.

sure if youre happy to set your machine up for one purpose only, modifying SWASH AFR may be easier for you as an easy way, but its far from the best way, and certainly not recommended by anyone I know.

Vortexgen: You should if your looking at the idle ups.
But the fact is adj the swash setting makes it easier
for the beginners. Now after you learn how to hover and handle
the helli than you can program all that sophisticated stuff.
+65 +65 +65 swash setting is more than enough for forward
flight. If i remember right that swash setting will get you
-4 +5 +11. When i started out i set the swash setting to
+50 +50 +50 and i feel like it helped me alot. After learning
to hover i bumped the swah setting up to +65 +65 +65
and went to forward flight. There is more than one way to
do things LOL. Now if i get to aerobatics than i will utilize
the pitch curves and idle up switches. I have a gv-1 governor(Screw The throttle Curves) LOL. If one wants to use my
method GREAT and if one wants to use your method Great.
THE POINT IS THERE IS 2 DIFFERENT METHODS TO CHOOSE
FROM fOR THE EMS SETUP AND THATS GREAT IN MY
OPINION LOL.

Ya know, I kind of like the idea of using the dual rates to limit my cyclic movement. This SWASH stuff is new and I'm not sure I completely understand it. Dual rate just seems familiar to me since I've been using it on airplanes for years.

Now, gyro sensitivity on the other hand is something I have no experience with. I've got mine hooked up to the idle up switch right now since I'm not using it. I think the idea is to have it set as high as you can (without twitching) for hover, and turn it off for forward flight. Mine is at 80% and off.

Mike.

Vortexgen

careful with off or 0% sens on a gyro. sure if your moving forward fast its not a big deal but most experts only reduce the sens enough to stop the tail from hunting. somewhere aound 30-50 is good enough to stop the tail hunting in forward flight in most cases.

for faster piro rates, simply use programmable mixing with rudder as the master, gyro as the slave, stick position as the switch.

This effectively means as you move your rudder stick away from the center (left or right) the gyro gain is reduced. The amount of reduction is programmed in the mixing. Most modern radios have this function available.

Yes randy, there are many ways to accomplish the same task.
In saying that, Im sure as soon as you begin using idle ups yourself, you could rapidly change the advice you have been giving. Great to see that you are always happy and doing your best to provide the most sincere advice you can, and Im sure everyone thanks you for it, including myself.
Keep it up.....

mlcasmey

Thanks for the help, the gyro I'm using is the Futaba GY502. The book says that in any sensitivity value over 50% it operates in the AVCS mode and below 50% it operates in the Normal mode. Looks like they recommend 85% for hovering and 15% for flight.

I guess I should not have said 0% for flight, I meant normal mode.

Thanks, Mike.

Vortexgen: You just may very well be right. I do take your
posts in consideration.I think you are a highly knowledgeable
person when it comes to hellis.
