I'm setting up my new Compass 6HV and I'm using a CY Mini-G gyro and Futaba's BLS 251 tail servo. I have the Futaba 9256 servo selected in the G view setup, which is listed as correct choice for Futaba BLS 251. Everything seems to be working OK except when I have my Futaba 8FG gyro menu set for 'normal' or rate mode for setup. In normal mode the servo still acts like it is in heading hold (AVCS). In other words If I move the stick left or right and let it return to center, the servo stays in the last stick input direction until I move the stick opposite. The gyro seems to work correctly when I move the heli in yaw directions...Should I disregard the rate/normal mode weirdness and maiden this thang....

Are you planning on flying in rate mode?

No, not planning on flying in rate mode but setting (hover) mechanical pitch on the tail rotor is usually done in rate mode with the Mini-G.

I believe Mini-G does not have a rate mode.

Mini-G has rate mode, Solid G does not...I have 5 other Mini-G's running on either 9257 or 9254 tail servos. All of these servos return to center trim as soon as I let go of the stick when in rate mode (normal) on my 8FG. Only the BLS 251 'sticks' like it is still in heading hold...Same receivers in all of my ships, R6008's in HS mode....The 251 is my first brushless servo and I'm just trying to sort out this different behavior...I'm begining to think that rate mode is disabled in the Mini-G with the 760us servos...???

it's not disabled in that mode. However it may be disables in your setup. If you have a G-view scroll through, until you find the rate mode option, and flip your HH/rate switch and verify that it is correct. Also stupid question but your sure you have both plugs plugged into the rx?

FIXED

Rate mode was enabled in the G-view and both gyro wires were plugged into their proper ports. However, I've been having some problems with the G-view spontaneously rebooting and/or the display not showing all the characters...? Whatever, I reset the G-view to defaults and went through setup again...guess what...the servo now responds correctly in rate mode...

Can you try just using End Points / ATV's?

I assume you are using the Gyro menu in the 8FG?
