The Futaba R304SB-E T-FHSS 4-Channel Telemetry 2.4GHz Receiver is only compatible with Futaba T-FHSS telemetry compatible transmitters. The R304SB-E is very similar to the R304SB (FUTL7680) in that they both feature 4-channels, both feature S. Bus2, both are Telemetry enabled and both costs roughly the same price.

However, the two receivers differ in two fundamental areas: this R304SB-E is only intended for electric vehicles and features the benefit of having a non-exposed built-in antenna. The R304SB is compatible with electric/nitro/gas applications and the antenna is fully exposed.

NOTE:

• The R304SB-E receiver is recommended for electric powered models only. This is NOT recommended for use with nitro or gas-powered models.
• Not compatible with the Futaba FHSS, S-FHSS, FASSTest or FASST transmitters.
