While I am still perfecting my hovering, I'm already looking into the future for which upgrade would make the most sense next. I currently have the Exceed RC 2.4ghz 6-channel transmitter, and although programmable via PC(T6config), it is very basic.

I do like the DX6i a lot, but I have read many conflicting articles and postings about the DX6i transmitter and a T-Rex 600 E version. Some say the DX6i works perfectly fine with 600-class, others say you need a 7-channel. Which is correct? Since the T-Rex 600 is the class that I will eventually focus on, I want to make sure my transmitter can do the job, without having to buy another one once I am ready for the T-Rex 600.

The other question I have is in regards to noise coming from my tail servo:

I have the Detrum GY48V gyro on my EXI 450 Alu V2. I can hear a constant buzzing sound from the tail servo even without rudder input, is that normal? I am using the following tail servo: T-Pro MG90S 9G, which is supposedly digital, therefore I set my gyro to DS mode ON.

I actually have an Align DS420 servo on the way, but I am curious about this buzzing sound in general...

Thanks so much in advance!!
