Yesterday, Santhosh and I were trying to use a DX7 as master and a DSX7 the slave.  From what I remembered, we needed to set the DX7 as P-Link in trainer menu, and set the DSX7 as "Slave/P-Link".  There is at least one other combination also, which SHOULD have worked. In our case, it never worked, and we quit trying various combinations after about 15 minutes or so, as it was getting really hot around 1pm. From what I remember, we needed to use a mono cable, but Santhosh had only a stereo one.  BTW, we had the slave turned off etc etc, so it does not seem like a "usage" issue.

A quick search seems to indicate that even a stereo cable should have worked ?

Anyone here who can confirm (or point to a link which says) that it absolutely takes a mono cable for this to work ?

Wow ! No one experimented with trainer cables for Spektrum/JR here ? 

tomorrow i am free,will try with all possible combinations, with a mono cable too

finally it worked here is the settings on the trainer menu

master------p-link
                 sw:L-rocker

slave------normal
               sw:L-lever
no flying today really enjoyed training kannan and anith on the buddy cord setup,more flyiers are waiting for you the next time ,used the same stereo cable

But we tried this already ?   Was it a mono cable ?

not sure abt the combinations we tried, its working ok now,now i enjoy teaching more than flying

Amen to that   Was at the field from 6am to 11am today, only flew my Funjet for 3 minutes.  The rest was all training, trimming, fixing models for others.... absolute pleasure !

no, in the evening started a bit late around 6pm and finished at 6.30pm.from tomorrow onwards we are planning to start around 5pm,am sure you can see more flyiers in ijk next time you visit, only if they keep the same spirit
