RJX Hobby Hurrican 50 - Xtreme 50 > Tail control rods Lengths?
 
 
pitch black

Hey guys.

Anybody has factory recommended lengths for the 2 tail control rods for the X5?

Im looking for proven lengths to compare mine against.
I have a tail/gyro control problem, so this might eliminate one of causes.

This goes out to RJX tech staff especially.

Thanx!

pitch_black,
here is the best method to it on your own:

Short rod:

Turn on your radio (Tx and Rx), allow the gyro to set, and then put it in rate mode, and make sure that the servo is mechanically centered.
then adjust the short rod length until the tail bellcrank is centered (vertical to the side frame).

Long rod:
Once youve completed the above step, find the tail blades 0 pitch position and then add a little "right" tail rotor compensation and start with that placement as your center. most gyros will work fine once you complete this.

If you wana have the best mechanical setup possible, turn on your radio, and start the engine and bring the machine into a hover in HH mode, and then flip to rate mode. if the machine turns right or left, land and adjust the long rod accordingly until the tail remains stationary in a hover.
Then make final adjustment of servo limits to both sides and enjoy your perfect mechanical setup.

PS -
1. if you could tell us whats the problem and which gyro \ tail rotor youre using it would help investigate the cause.
2. i forgot to mention - make sure trima nd sub trim of rudder channel are at ZERO.

Good luck !

The short rod should be at 270mm center to center of link with the servo at exactly 90degrees the 630 rod what I done before I glued in the ni rods for the links was fitted it perfectly to where there is zero pitch on the tail blades and scribed a line on the nirods up against the carbon rod so I knew where to stop when I glued them in.This got mine perfect.I use the JR7703D/8900 combo witch works well for Me with this setup.I hope that this info is helpfull as I wanna say that the tail rod came out somewhere around 680mm or somthing like that as I never really measured that to close only because on the tail rod is where I like to tweek it perfect by moving the nirods in and out to get the tail pitch at zero with the links just a few threads from bottoming out to leave alittle for slight tweekage.

Pitch,this may be an issue in the gyro itself as the travel limit on the gyro may not be starting at center and allowing the travel more in one direction.I would not hesitate to have this checked by sending it in for a look/repair.I have had this issue on one of My 401's on one of my old Rappy's.I would have that checked bud.

Hey guys.

Solved the issue.
But another one has arisen, and it's not a new problem.

Some how or rather, my tail CF rod, seems to like to splinter.
When i mean splinter, i mean as though somebody stepped on the rod, turning it into halves or carbon strips.

This is the 2nd time it has happened.
Both have been Original RJX carbon rods.
I don't see any visible vibes that could give rise to the issue.
The crack lines end before the CF rod ends too.

My tail guides have been CA-ed in place, and allow the rod to be straight.

X5 techs! Need help here!

Thanx!
