Hi, I just want to share my Futaba settings for Futaba/Vibe 50 owners. I wish someone would have done this before I did my build. I could have saved a couple of hours of tinkering... So many more people use JR/Spektrum radios so Futaba stuff on the forums is pretty rare. These settings have me flying super smooth with rock solid tail, and "Stays where you want it" hovering. Note: I'm set up for 140 deg. swash.
I have +12&-12 Blade Pitch
RADIO: FUTABA 10C (W Included 14ch RX) (All JR SERVOS)

Servo Reverse: AIL,ELEV (Gyro switch (ON THE GYRO) in reverse position also)
SWASH MIX (AFR): +50,+50,+35
GYRO SENSE (W/G7703D) 23% HH mode
Note: Remember Futaba is 1:1 Gyro Gain! 23% on Futaba is approx. 67% on a JR/Spektrum radio!

These settings are what I am using for basic FF and hovering. Make sure ALL SERVO HORNS ON THE SWASH AND TAIL are PERFECTLY 90 degrees, and all linkages match without binding. MAKE SURE swashplate is level with sticks centered and, ALL THE WAY up and down the main shaft. It may be a pain to get everything level, but well worth it.

Nice you posted your values.

However, it really depends on each setup. I also use futaba and my values were more like +55, 50, 50 to get 7.5 cyclic all around and 12.5 pitch

About the gyro, it depends if you mount it with the cable facing forward or backwards.

About the cyclics, depends also where you plug in your "pit", "ail" and "ele" servo. On futaba systems, the servo most back is the ele servo, the one on the front right is pit and on the front left is ail but you can mount them otherwise and just reverse the signals in the swash menu and reverse some servos. There is more than one way to setup the ccpm.

Seal,

How far in MM is your link ball out on the tail rotor servo arm? AND what tail blades are you running? As well as Headspeed with that gain value?

Tony, I agree...That's why I stressed that these settings were for ME. My setup is capable of +13/-13 but I have it dialed down to 12 in the radio.

Onquick. I didn't install my Multi Gov yet because I want to get the engine dialed right first. So, I have no Idea what my accurate head speed is. For tail setup I am @ 23% FUTABA GYRO SENSE (67% JR/Spektrum), I am using the KBDD 92mm blades (way better than stock and CHEAP!) I am using the ball link on the OUTSIDE of the servo arm, and the same hole location as per the manual.

Hmm, you need to check your setup. My Vibe 50 was over +/-14 degrees with the manual settings in a X9303 with 8717s. And there was MORE available.

Only my opinion but I think the standard tail servo arm length of 17mm shown in the manual is a bit long for me, I've used I think 13.5/14mm instead - works great.

+1 I have radix 92mm tails and I had to go in from 17mm to 14mm. I was getting tail wag in idle up at 58% in JR gyro menu with the ball at 17mm. Going in to 14 has helped a lot.

About the gyro, it depends if you mount it with the cable facing forward or backwards.
Eh? It makes no difference which way round the gyro is positioned, the rate of rotation is the same. Now if you invert the gyro (so its hanging down), THAT will change the settings.

Or did I miss something?

He is saying that depending where the cable is facing on the gyro will depend on wether it will need to be reversed or not which is true.

Why would the position of the cable or the rotational position of the gyro make any difference to the reverse setting? I assume that if the cable is at the front rather than the back, the gyro is essentially 180 degrees rotated. Its the same as rotating the heli 180 degrees, and you don't need to change any settings on the gyro then

its the opposite. left becomes right and right becomes left IF both gyros are at the same location (ie in front or behind the shaft).

what you saying (180 degree swing) would only work if you move the gyro from front to behind the mainshaft and rotated it at the same time.

I could make a drawing as this is kinds confusing to explain. Just try it on the bench.

PS. Ok, I didn't understand half of what I just wrote myself lol. Here is a pic:

True, my Gyro wires are facing the REAR of the heli. I DO have a-lot more pitch available also. I measured about +/-16. I am not getting any tail wag, even in Idle up. The green KYOSHO ZEAL anti-vibration tape is awesome!

Well I thought you had me...but I think I can prove you wrong (which will be interesting if what you say is true in practice but I don't believe it is!!!!!). I printed the drawings out. Then I thought, it can't be true as what happens if the gyro is rotated only 90 degrees, or 45 degrees or some other angle rather than the 180 - there's no switch for partial reverse.

With all 3 drawings in front of me, if I rotate the pieces of paper clockwise (right rudder), each of the 3 gyros also rotates clockwise on its own axis...doesn't matter if its in front, behind or to the side of the shaft, wire going forwards, backwards sideways or any other direction.

Try it..!

Want to prove I'm wrong? Be my guest. I'm sure we will all learn something from this whatever the results are

It is true beacuase otherwise why would you need a reverse switch on the gyro. Remember the switch doesnt reverse the servo it reverses the gyro's correction output.

I may need to look into some beter gyro tape because I have heard some people say that the 770 is sensative to vibrations and can cause tail wagging. Maybe that is part of it.

And now that I think of it, I remember needing to put my MS piece of sh** gyro upside down because it didn't had the reverse switch... but then again, I kept it exactly in the same place as there wasn't any space upfront in that little piece of cr** called hornet

This is going to be fun

Hum

I think we are both right. The switch isn't reversing the gyro sensor per se but reversing what signal it should give to the rudder servo. The gyro has no way knowing that giving +100% to the rudder makes it turn the heli clockwise or counter clockwise so basically you reverse the signal it gives to the rudder when it detects an unwanted movement. Helis with levers and with the servo mounted in the front will have different settings than servos that are boom mounted. Same goes to JR servos vs futaba ones etc etc.

What I'm trying to remember is if i had to reverse a gyro while on the same heli or just when swapping a gyro between diferent machines

Gyro reads rotation. Clockwise or counter clockwise. NOT left or right.

So direction the wires point has nothing to do with anything. Neither does in front of or behind the main shaft. Also doesn't matter whether you put in under the main shaft or on the tail gear box, or on a stick 10 feet long sticking out in front of the heli.

ALL parts of the heli rotate the same amount and the same speed (excepting the rotating parts like motor, geats, head, main shaft, tail drive, tail).

Dr Lodge is right. The direction of the cable does not matter. The gyro senses clockwise and counter-clockwise rotation which remains the same whether the cable cable is facing forward of back.
