Beastx tail Trex 600

[Vanquish]

Can anyone using a Beastx on a Trex 600 tell me what distance your tail linkage is from the centre of the tail servo horn?

Also what setting are you using for the tail heading hold (parameter D)

Cheers

I watched Sam fly his heli on Sunday and the tail was blowing out big time.

Unfortunately he failed to bring the instructions so trying to make adjustments at the field from memory isn't good practice.

Fingers crossed someone will chip in with some parameters and hopefully get you sorted mate.

It seemed fine for normal flight Tim, it was only when I started to work the tail hard in a funnel or fast stop that it blew out 45 degree's or so. Tbh moving it out to the outer hole on the horn seemed if anything to make it worse so I might try moving it in one and playing with the tail heading hold setting tonight and hopefully it will be better for tomorrow

Can I ask what tail blades your using Sam?

For info I had the round align horns on but could never get rid of a bit of wag in ff. I spent an afternoon with it and ended up 12.5 from centre with a Futaba horn, got the gain up to 45 and head hold lock on standard setting with the dynamic up around 2 marks.

I was using KBDD tails and they were fine until really pushed and I found them start to let go, put Align carbons on which stiffened it back up but resulted with the wag now and again.

I'm using the standard align tail blades. I have a futaba star shaped horn on a DS650 with the linkage on the second last hole which is around 12mm from the centre of the horn I think. I used the same beastx unit on my 500 and it never blew out once so I think i just havn't got it setup quite right. Only thing i can think of is to play around with the tail heading hold setting.

Do you mean you have you gain at 45 in your tx or 45 relating to the lights on the beastx?

I can but it will only be approximate for your setup. The optimum position will depend on main rotor and tail blades and hover pitch/drag etc.

Best way to set it is by using rate mode on the beast and adjust the linkage so the tail holds with no trim (fly into the wind). Then reset into HH Mode.

Trying to copy someone else's settings will only be approximate for your model. Don't forget that some people set the tube further back out of the block and this effects the length of the rod. On Electrics the boom mounted tail servo may not be in the same position as yours.

Gyro gain will depend on ball joint distance from servo centre, Servo type/speed, how smooth your engine is, your tail blades, govenor type and what pad you are using under the beast. Start at 35% and work from there.

Best of luck, I hope that helps.

It's a Dx7 and the Tx gain is at 45

Both my'n are on 13mm i have just put EDGE tail blades on all my beast x an have found with edge that i needed to
drop the gain a little i figure that edge are more active than the stock Align.

beastx unit on my 500 and it never blew

Thats funny Sam... I'm having those problems on my 500 but not on any bigger heli's and its doing my head in trying to sort the 500 out!

On the 600 I have the beast Headlock at Low and Tx Gain at 48 with the ball on 2nd hole in (from outside) on a Futaba horn.. I'm using Edge tails aswell

When you say standard Align do you mean the plastic or the carbon ones.

Carbon ones bud, we have several people at MFHC on beast x and V bar, we are all on edge tails and all solid!

I'm using the align carbon blades.

Just out of interest, when setting your tail throw end points at point E in the setup, are you setting them as far as they will go without the tail slider binding? it seems on the 600 tail that you can go further one way without the tail slider binding than the other if that makes sense. Surely you have to have equal throws in both directions?

It says in the manual you should set the maximum end points in both directions without them binding but not so far that the blades stall in flight.

From them manual:

At setup menu point E you adjust the best possible servo throw for your tail rotor. This best throw is determined by the maximum possible control travel of the tail mechanism or based on the maximum allowed angle of attack of the tail rotor blades, that will not lead to an aerodynamic stall of these blades. Such stalls can cause very bad stopping behavior.

Id be interested to know where other people are setting their tail endpoints on the 600 and if there if is a maximum sensible tail blade pitch.

Full throws each way without binding Sam.

Thats where I set mine at.

I had them set at full throws at the weekend, but when i went through the setup just now it seems you can get more throw in one direction than the other obviously resulting in more pitch in one direction than the other when moving the rudder from one extreme to the other. Are the tail units designed to get more throw in one direction?

[waveydavey]

You naturally have more left rudder than right as you already have 7 or 8 degrees right to offset the torque induced by the main rotor. Just set it at full throw without the tail links popping inwards.
