I have seen some discussion in the past about the 361 being identical to
the 368, however I have found differing specs between the two.
DS36128x30x13mm18g0.15s/40deg
DS36828x30x13mm22g0.11s/40deg
The two servos are NOT identical. I have examples of both with a 'spec'
sheet for the 368, but not for the 361 as they were purchased in 'bulk' at a
German model show. The case is the same, but the 'innards' differ. First
the 368 has metal gears while the 361 has plastic gears. The gear ratio
appears to be the same but the 368 is visually faster, which matches your
information. The weight difference is correct, based on my servos and, at
least in part, reflects the difference in weight between plastic and metal
gears.
I believe the difference between the two is the 361 has a 3 pole motor
whereas the 368 has a 5 pole, can anyone out there confirm this??
Short of disassembling a motor, which I'm not going to do, I haven't a clue.
I suppose I could check the resistance of the windings - and I found that
impossible to do as the circuit board is soldered to the end of the motor,
making it VERY difficult to isolate the motor from the drive circuit to get
a correct resistance reading.
There were some rumours a number of months ago that the 368 was to be
discontinued, does anyone know if JR Japan has simply been putting 368
stickers onto 361 servos for the US market, I have heard that from at least
one source fairly close to JR Japan.
It would be immediately obvious if they were doing that, as the difference
in gear materials would be obvious if you took off the output arm. I can't
imagine JR being so naive as to try to pass this off and I certainly can't
imagine Horizon going along with it. In retrospect you need to have a
serious talk with your 'source'.
There was a short period when the 368 was not available and the RUMOR was
that it had been discontinued. A rather silly rumor as this is one of the
better selling servos for JR, at least with the sailplane crowd. At the
time I had hoped they were retooling the case molds to include a ball
bearing, a stupid omission for a premium, digital servo. However, so far I
haven't seen any significant amount of slop develop as a result of case wear
around the output shaft.
