Hey Gary.. After switching to the new receiver and still having the same problem
and remembering what a club member said about me flying an awful lot and that
it could eaisly be a broken wire on the rudder gimbal, he even told me it would be
an orange wire and sure enough the orange wire had broke.. I soldered it and
shrinked wrapped and all is like new and all works great.. I left the new
receiver in and will still send the other in for a check up... Will try again on tues or
wed....

sdcranford.... The YS 63 flew the "Do" great!!! But in this AZ heat with less lift and
lost in power during the "HOT" months, I started looking for another power plant, I
was going to go with the S-82.. I also think this is the best for the "Do", but found
a "GREAT" deal on "new/used" S-100 so I went for it... I think the YS-63 is close or
at the power of the S-82, but the Saito will turn a bigger prop..
You said you had a 4*60 waiting for the Saito 100... When I got the Saito 100 and
since my "Do" was still in the repair mode I put the 100 in my 4*60, to "test" the S-
100 out, I had been flying it with a Mag 91... I loved my 4* with the 91... But WoW
the S-100 did so much more for my stock 4*.. It would hover till I ran out of fuel,
I did K.E. circuits, K.E. figure 8's.. The S-100 made my stock 4* so much better:-)
