RJX Extreme Glitching problem

[skurniaw]

Can anybody tell me why It seems that RJX Extreme is very sensitive to radio interference ? This problem occurs only on the Carbon frame version. I have several friends who bought this heli, and every week I heard that one by one fell down from the sky. Is it because the quality of the carbon frame ? Since we do not have this problem on Avant, Stratus, or even Eagle 3.

it has nothing to do with the quality of the carbon frame unless the other helis had "fake" carbon frames, (which they dont), You need to be certain there is no carbon / carbon and carbon / alloy parts rubbing together or rattling around. That is big RF trouble. The only spot I saw that could be potential trouble for RF as far as carbon to carbon interference was the interlocking pieces in the frame. (gyro mounts and radio tray) You can CA them in place to avoid them creating trouble. Also, where the boom struts meet the frame in the back, you can install some nylon or plastic washers between the boom strut end and the carbon frame. Those couple places I would be real diligent with. I am running mine on Futaba's 2048 which is VERY prone to lockouts and have been ok so far. I am still going to get the fasst module as soon as it is available. Ahh, also there has been talk over the past few years of static discharge from belt drive systems. If you lightly lube the tailbelt with WD-40 it takes care of that.

There has been no reports of RF troulbe, but as doctorgoodwrench has pointed out these are areas that you may want to inspect close on your model to see if there is any residue present due to rubbing. The tail belt works free and less static if applying wd-40 or a silicone spray either will work good.
Thanks

Thanks for the suggestions. I will inspect it and will inform you later on the results

hi skurniawan thanks for the thread,
it's mine Extreme CF have this problem,after a 3rd flight i going FFF suddenly it glitch and crash my extreme,i use a JR radio i think that my JR radio problem,after that i'm going to G10 frame and change to 14mz radio, now i have more than 15 flight and dont have any glitch problem.
But last sunday i also set 1 of my freind CF extreme, using a 14mz radio with pcm 1024,and fly it than crash cause by glitching problem,

And i have a 2nd freind also have a same glicthing prob than crash,he is using a CF extreme with a JR radio,then he have mail to Phil Lennert on takeoffandland.ua.com,
he said he also have a same problem,after he change to 2.4GHz radio and CF extreme now the glitch prob are gone,
so we must change to 2.4GHz frec...?

I've been flying a Hurrican 50 007 full carbon/metal heli for 1 year this month, it is on a Futaba 149DP receiver with a deans whip atenna, I had the antenna wire separate from the deans whip right where it comes out of the plastic, we have never experianced any glitching with this setup on 72mhz.

On the 003 G-10 demo kit I have, I've changed it over to an XPS Xtremelink 2.4 system on my 9Z flying for 4 months, again zero problems, now the silver carbon Xtreme was built with an 8ch XPS on a 9C the beginning of August the weekend before IRCHA and we have not had any glitches.

I've also got a pair of Predator carbon P-Max's and carbon Gassers SE, all running 149DP's and have never had a glitch in 4 years from any of them.

I would suggest looking at where the antenna wire is run, remember the Xtreme has carbon landing gear also. Location of the receiver, routing of wires, are the servo wires protected or just laying up against the carbon frame? I put my servo wires in a protective sleeve when up against the carbon frames.
