Hello

I am facing a problem with the tail of my Titan x50 Belt version.I am running BEASTX with Torq 9188 tail servo.

While in a hover in whatever flight mode i am the tail slightly kicks to the right every 7 to 8 seconds.
Iv played the gains but it didnt effect,the engine bearings are good,belt seems fine and the other bearings seem okay as well.
The engine might be slightly un tuned and running a bit rich.
Last thing which came in my mind was to check the tail blade position after the beastx has initialized.
My sharp side of the tail blades was slightly facing the boom after initialization.I managed to tighten the links so that the sharp side of the blade faces on the other side,im not sure if this theory is correct but i remember i read somewhere.Now the blades are facing the opposite side of the boom and are around 5 to 6 degrees out and the slider is not in the center.
After doing all this the kick has become very less.It only kicks in hard maneuvers may be once in a complete flight.
Can anyone tell me what can be the issue,is it the angle of the blades which was making it kick or may be some other problem which i dont know.

Regards

Here are a few things you can try:

Could it be the tail servo has a twitch in it? Check it with it just sitting on the bench, not spooling it up will the tail twitch?

Could it be static from the belt? Spray a little silicone on the belt and see if its any better.

Could it be from a vibration on the heli somewhere, Blades balanced?

Tail servo doesnt have a twich as i checked on the ground,Atleast i waited for good 5 minutes but there was nothing while the engine was off.

The heli doesnt have any vibration and the blades are well balanced.
Might be a problem with the belt because it has been lying for good 7 to 8 months and i dint fly it,should i replace the belt or should i use WD 40 spray on it

dont you think the angle of the tail blades have made any effect, or it might be something else

As Wrongler says it could be static from the belt. It could also be the rich running engine you mentioned.

What mounting tape are you using under the BeastX? You want to use just one layer of the grey red backed 3M tape that comes with the BeastX now, don't use the thick white tape it is known to cause problems.

So spray the belt with silicone spray, lean the motor slightly and check the mounting tape. If the twitch is still there its time to start balancing things (assuming all shafts are straight), main blades, tail blades and engine fan. Its maybe easiest to buy a new fan or try unbolting it from the hub and turn it 90 degrees at a time and try it, its a long tedious process but it will pay off.

60% of the time, it works every time!

Definitely something else. With the BeastX you want the pitch slider in the center of its travel, this will either put the tail blades at 0 degrees or a few degrees against rotor torque, either will work just fine.

Remember to check you have smooth and friction free operation of the tail pitch from the servo end (uncouple the rod from the tail servo and move the tail pitch by hand to check this).

60% of the time, it works every time!

okay firstly im using the 3m clear mounting tape and a single layer.ill move the pitch slider in the center again and spray some wd 40 on the belt,will check the rod also if there is any friction,
The fan is perfectly fine as i just checked it,
will check the belt and spray on it

If your motor has a known out of tune condition it could be changing the RPM on the head suddenly either lowering or raising the RPM and the tail servo may have a hard time keeping up with that. I would tune the motor and then troubleshoot the tail. Make sure it can hold a constant RPM without sputtering or surging. I always set my tails up with a 2-3 degree bias and never have to touch it again after that.

yes i will tune the engine and will let you guys know,lastly should the belt be removed and then sprayed on or can we spray it with the belt on.
Will centre the slider again and set the tail 2 or 3 degree

yes tune the engine well.. Don't use wd40 on the belt, creates an awful mess. regular laundry static guard or silicone spray works best

MY Titan X50 had the tail rotor pully come apart. I had to replace the aluminum one with a plastic one from the Raptor 50. The only replacement that was available at the time from Heliproz. I suggest taking the tail apart and make sure everything is kosher.

while you have the belt out, check every tooth on it.
sometimes they get "round" and skip.
or it's missing a tooth all together.
