@nikolajc7617 the short answer is....no..I can't really explain why . I'm sure I bus or S bus really comes into play with drones and small stuff where weight and space becomes an issue....
@@okiedoak201 Okay, i only have cars, but i have a radio with 4 channels and a receiver with 4 channels and it have I-Bus, but when i set I-BUS receiver on i only double the channels to do the same thing times 2, i thought i could get 8 channels with 4 on each receiver.
@nikolajc7617 yea....this is where the modern rc systems are advancing faster than I can learn and utilize the practical functions...honestly...I'm totally fine with the PPM(wires into the reciever) and never had an issue...but...it is kinda cool to learn a new trick or two...will I use it...remains to be seen.... Oh...then there is the SPEKTRUM radio and all there stuff....
Ok..so I'm doing some digging...and thisnis what I found....I cut and pasted the answer from RCGROUP.COM... Hi, i-Bus and S-Bus are digital, serial protocols for data transfer. They're digital in that they send numerical data rather than the analog timing data used by PWM and PPM. PWM uses multiple channels each sending analog timing data. PPM uses a serial format so a single channel sends all the channel data one after the other using analog timing intervals. The serial formats are used with a flight controller and allows a single connection from the receiver to the FC. i-Bus is the system that Flysky uses whereas S-Bus is Frsky (but based on Futaba protocol) so depending on what receivers you have this may dictate your choice. i-Bus is elegantly simple and is effectively 115,200 baud serial data. It also allows telemetry data whereby the plane/drone can send data back to the transmitter, indicating signal strength and battery pack voltage. Frsky later brought out Smart Port telemetry to address the need for data from craft to tx but it required a second (precious) UART. Still later they introduced F-Port which combined control data and telelmetry over a single port - just like Flysky had all along.
Can you explain to me why you need an I-Bus receiver when your receiver already have the channels???
