i just ordered one of these radios before remembering that there is something beyond channel that makes a tx and rx work together.

i'm curious if i'm going to have to buy new receivers for my existing modules. i have an airtronics transmitter (old SR i think) and am using it on a model with a cirrus micro receiver (not sure pos/neg shift?). i guess i just got lucky becuase it works with that receiver.

is there an easy way to know what receiver will be compatible with this transmitter? i need to purchase a new receiver for a plane i'm almost finished building.

Ace Alpha .061 with full size Airtroncis receiver (using Airtronics SR tx)
Mad Max 3d with micro Cirrus receiver (using Airtronics SR tx)
Feda Dragonfly w/micro feda (??) 6ch receiver (using cheap futaba tx)
GWS PicoJ3 (need to purchase receiver)

i'm purchased the Eclipse 7 so i could use one radio for all 4 of these models. at the moment, i'm windering if i'm goign to have compatibilty problems and haev to buy all new receivers?

thanks
