Radio - Servo - Gyro - Gov - Batt > ?? About 460T switches

Just got my JR460T out of the box to have a look. The TL and RW switches seem awfully small as in almost not there. How do you change their position, with a stick pin? Is this normal or do I have a problem??

The same thought hit me today to.
If mounting it at the Gyro tray on my Caliber30 the switches will be pointing towards a "wall".

And I just orderd a JR550T Gyro and a NES810G servo.
Likes the option to switch between HH/norm from the TX.

'Hm now I just have to find out where to connect the GV1 sensor to the Jazz80 ESC.

>>bosco and all others pls check the above topic.

I bought a 550T and it looks good, do you have any suggestions about setting it up, I´ll be using a NES810G and a JR3810 ADT. As its connected at the moment its setuped to switch between HH/norm. with flightmode switch.

Standard: HH
Mode 1: Norm
Mode 2: Norm

And when i power on the radio in standard mode (HH) and waits 3sec. it seems ok, and then switches to norm (mode1 or 2) the servo overrides the tail pushrod lengthon my Cal30, should I adjust this by changing ATV for mode 1&2? Or whats the best way to solve it?!

bosco,

Go into Code 83 and reduce your Rudder Trim rate to 50%.

I have a JR 460T gyro, and simply cannot understand all the complaints about it. It works just fine.

Yes, it drifts a little. ALL gyros that use a piezo crystal element are going to; nature of the beast.

As to the switches, if one wishes to be able to switch back and forth between Normal and HH modes at the transmitter, then get a Futaba 401. Once you have your gyro set-up, there is noi need to fool with those tiny switches unless you change your set-up. I agree, they ARE damned difficult to manipulate

Had/have the same problem..

I have a 460 that is back at Horizon right now being checked out (been there for about 2 weeks!) for the exact same problem it seems. It would hold for about 30 seconds but on spool up it would go full left or right and lock there.
I fixed it though (put a 401/9253 in ).
Steve I take it code 83 is a JR thing?
I am going to give mine another try on a Hawk I am building when it comes back.
Until it started this (of course it was after a crash!) I found it to work ok with a bit of drift.
I also used the tip if an X-acto knife to switch them. After you get it setup you don't need to switch back and forth really so it is kind of a non issue.

Jason,

Yeah, the 10-series JR radios use codes for each menu; 83 is for Trim Rates. It determines how the servo moves/reacts to inputs. By reducing the rudder trim rate, you are actually limiting the amount of the signal the servo sees.

Some have said this greatly reduces the servo's response. I certainly have not seen it, and I've been doing this since Bill Meador figured it out back in 1996. It nearly eliminates drift with first-generation piezo gyros; even the Arca-Wag

Bosco, this is not a cure-all for poor set-up and/or crash damage. If the servo is moving hard over to one side, then something else is wrong. Either the piezo crystal in the gyro is cracked (and going hard over is a symptom of this), you have a servo pot going out, or it could be any of a number of other maladies.
