Direct answer: If the Eagle 2000 FR has an EG650 or EG652 Chrome receiver, use a Chrome-series transmitter such as EG640 or EG642. If it has a different receiver, match the remote to that receiver instead.

Why the receiver matters
The Eagle 2000 has a pre-wired receiver terminal and Eagle states that its operators can work with different receiver brands. That makes the receiver model the decisive compatibility fact.
