Hopefully, some of the online stores will have Father's day sales this weekend but I'm pretty sure I'm going to go with the 14SG, either way. My DX8 has telemetry but I never used it. Maybe since Futaba doesn't require buying an extra module to plug the sensors into, I'll use it.
As for receivers, since the SK540 is S-Bus compatible, can I use the R7003SB Sbus-2 receiver instead of the R7008SB?
