Hi

I have a strange problem,

JR8103
JR649 PCM Receiver
JR550T Gyro (AUX 2 - f.mode controlled)
GV1 Futaba Gov (AUX3 - f.mode controlled)
CCPM is used

I have no MIXES, no EXP, no D/R and while I go from Stunt-1 to Stunt-2 the swashplate tilts backward about 3deg.
So the 3 servos are "moving" to provide this action....

After a couple of minutes I thought, there might be a Stunt SubTrim applied (this is not my radio/machine). But the Stunt SubTrim function is just not there, eventhought it's shown in the manual ...

thanks

Is it a DT (digital trim) transmitter?

When JR shifted to the DT version of the 8103, they removed the 'Stunt Trim' function.

Instead, the electronic trim tabs adjust the trims seperately for each of the flight modes.

Check the elevator trim tab indicators on the LCD while shifting flight modes. That will tell you if the trim setting are different.

That's exactly it ... I did not "know" that DT would carry over flight modes.

problem fixed, thanks

When the DT version hit the street, JR didn't immediately update the manual. Instead, they slipped in an Addendum page that was easily misplaced. As you noted, the Stunt Trim function was still in the manual yet not in the radio.
