Also i heard rx601 can't do cppm. what does that mean??
I would recommend going with the newer r620x. That gets you telemetry for flight battery voltage and flightlog data, both of which are nice to have. It's cheaper than an r615x and a telemetry module. No rx battery voltage, but a 250 quad probably doesn't have one of those.
Since CPPM gets you all your channels on one pin, you aren't limited to the number of pins for your channel count. While the r615X is 6 channels either way, the r620X is 12 channels. It also comes in an SBUS version (like CPPM, but a different wire protocol). Make sure you get the one your flight controller and any other devices can speak.
Similarly, you can go down a step, and get a r415X. No telemetry, but it has 6 channels in CPPM mode.
