I would appreciate any tips or input in using the JR XP8103dt/649S transmitter/receiver with Futaba's GY401/S9253 gyro/servo combination.

Thanks

Only tip I can tell ya is that Futaba gyro instructions arent generic and show only futaba TX setups no JR setups. Therefore, use your JR manual to adjust and setup your remote gain via RX ch7 and the rudd dual rate sw. for HH and non HH. other than that follow the Futaba instructions.

I am using a Futaba's GY401/S9253 on my Raptor 60 with the JR 8103DT. It works ok. You can use the Gyro Senstivity setting in the 8103 to control the gyro. When setting it up any setting above 50% will be heading hold and any setting below 50% is rate setting. I have my settings at 75%(50% Gyro Setting) in Normal and 70% (About 40% Gyro Setting) in Idle up 1.

I have had the gyro act a little funky around 50% radio setting. I had to either go up or down a few percent.

You will have to trim the connector tab off to fit the JR Receiver.

Just remember that when setting it up that the setting goes as follows:

Heading Hold

Radio Gyro
50 % 0%
75% 50%
100% 100%

Rate Mode

Radio Gyro
0% 0%
25% 50%
50% 100%

Hope this helps!

Tazhd, be sure to be certain that you have full throw both dir on the rudd servo but no binding thats critical! Then use the rudd ATV to set your piro rate speed. Mine is at 120% both dir and wow thats fast. Use your expo on rudd to mellow out the hover, im using 15% myself. I couldnt get mine to wag but its working well so dont be overly concerned if it wont wag as long as its working with a strong tail lock. My ballink is 20mm out on the servo. Im using a large wheel on the servo more solid, and allows a bit farther out than the standard arm does. Hope Ive helped.

Just an FYI

52% is where JR radios with the 401 Combo usually kick into Heading Hold. May be a % up or down - but that is where you should start.

An average radio setting would be:

Normal Mode: 65%
IDLE Mode: 55%
Throttle Hold: 55%

Start with those %'s and make adjustments accordingly.

Also, make sure that you connect your 401 combo into the AUX3 ch - NOT the GEAR channel. You wont be able to set HH mode when you go to IDLE if you dont have it connected to AUX3.

Thanks,

Wild Turkey
