Sorry, I meant to say FHSS

I understand that in the middle it says which ones are compatible, but what I dont understand is the different between the $35 ones and the $60 ones.

I see some are 3 chan, some are 4 chan, and obviously the telemetry one is more expensive, but all these work:

R603GF (3CH) $54.98
R2004GF (4CH) $47.99
R203GF (3CH) $37.99
R204GF-E (4CH) $37.99
R2104GF (4CH) $44.99
R2006GS (6CH) $29.99
R2106GF (6CH) $29.99
R2008SB (8CH) $49.98
R304SB (4CH) $59.99

These are all tower prices. Now, my 4pls will come with a r304sb.

I bought a R204gf-e on here used, I like that it doesnt have an antenna.

To convert my vehicles from my flysky setup Ill probably buy a batch of 4 receivers (tower offers quantity discount, plus coupon codes, plus free shipping gets em pretty cheap!)

But I dont know which to get! What makes the R603GF so expensive? What stops me from getting the R2006GS for $29.99 and just using 2 channels?

I cant find what the differences are between the receivers.

I exclusively bash, no racing

I drive an sc104x4, rc8te, rc8.2e, brushless MGT, etc

Please help!
