Being new to this hobby I am attempting to find out as much information about the electronic components as I can ... I currently own a Futaba 9C Super which came with a 9 channel T9CAP Transmitter, a R149DP receiver and 3 - S9252 digital servos and 1 - S3151 digital servo.

I have directed some questions to a few suppliers but am not getting straight answers: Obviously Futaba would say to only purchase Futaba but there seems to be some people saying that it is possible to interchange parts.

Assuming a 4.8 V battery Pack and understanding that each of the manufactures may have different pinouts and or connector configurations for their components ie buddy boxes, servo's etc;

1) Is it safe to assume that the receiver interfaces (signal lines) to servo's are electrically compatible. ie would they be expecting the same signal levels?

2) Is the receiver I have only able to control Digital Servo's? Basically there was some discussion that there is no difference between the signals going to a digital servo or an analog servo ... however that the digital servo's can be programmed?

3) Are the signals and electrical interface required for buddy boxes compatible ... ie could a Hitec Radio act as a buddy controller to a Futaba radio or visa versa?

4) My understanding of the Futaba radio is that it has the ability to store configuration info about a given plane ... when the radio interfaces to that plane it uploads all that info to the receiver stuff like Auto Fail Safe, endpoints and rates . I am not sure what components actually hold that info? (ie does the servo know its end points or is the receiver making sure that the endpoints are not exceeded or possibly the Radio itself is doing this memory game? For the Fail Safe I would assume the Receiver is responsible for this logic because it has to take control when it looses signal?

5) I want to build another plane for next season and would like to have another flight pack so I don't have to remove the flight pack from our trainer
so would like to be able to order compatible components without necessarily having to order exclusively Futaba parts. With the exception of the frequency and PCM compatibility is there any other issues that stop me from purchasing a receiver other then the R149DP?
