The 7955 can be programed for up to 180 degree throw,, I wouldn't worry too much about hurting it with the TX @ 150% EPA
That's one of those "yeah but...." deals....
First, you cannot run high resolution if you want the 180 degree sweep and the OP didn't mention whether or not he has a Hitec servo progammer?
Second, as mentioned above when you do that the actual linear movement produced at the control surface doesn't change a whole lot.
Third, "assuming" the use of JR tx which has a 150% setting where Futaba uses 140%, it's never a good idea to push the tx that far for reasons already mentioned....[8D]
