This Futaba 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 cost roughly the same price.
However, the two receives differ in two fundamental areas: this R304SB-E is only intended for electric vehicles, the R304SB is electric/nitro/gas, and this R304SB-E features the benefit of having a non-exposed built-in antenna – the R304SB is fully exposed.
