[NSRCA-discussion] DX7?

[Bob Richards]

John,
   
  I have been using a TM-7 module in my old 7UAP, it will also work in the 9Z. I have been happy with the performance of the module so far. The TM-8 should be out before long but is much more expensive, not sure why. If you don't need channel 8, the TM-7 is the way to go.

I have been using a Futaba 9ZAPS since the mid 90's so I am spoiled with 
features. I don't use many of the features, but I would miss not having them 
available.

Coarse trims are a definite deal breaker.
It looks like I might be better off with the Futaba FASST adapter.
