Problem: Last fall I bought a Hitec RCD 3500 RX & upon hooking it up in the plane I eventually figured out that servo outputs 2&3 were reversed was going to use it & just move the plugs but the trims don't work so it's no go .. upon checking my collection
to varify I found that an old 555 rcvr had swapped 2& 4 outputs since last flown in Oct. ( Checked with 2 Xmitters a Flash 5X &
anOptic 6 with a module. both lashups exhibit the same behavior 3 other planes OK) ( billand [email protected])

Not sure your question is fully understood but suggest re-try with Optic 6 using one model in memory which has been reset to factory default, this to ensure all mixes etc are removed.
