Imo the Spektrum Futaba 2.4 module sucks. It still unlike the JR version still uses a wire to the antenna that is placed on a adapter you install after removing the 72mhz antenna. Also I need to remove the 2.4 antenna before putting it in my tx case and if you press it in on so it doesn't fall off it is hard to remove. Something is going to break. Also I wonder if the little connector on the module will get broken when placing the tx in the case since it sticks out on the bottom of the tx. I have many planes and can't afford and really have no need to replace all my 72mhz rx but I worry about having to remove the antenna and install the 2.4 adapter every time I want to change to 2.4mhz.

As far as the Spektrum part the 2.4mhz mode seems to work fine to bind a AR7000 and AR6100e rxs. I have not flown yet so I will need to do good range checking before flying.

Now that I have setup the rxers the manual make prefect sense but it didn't when I had not figured it out. If it were not for hearing people at the club, on rcgroups and here I do not think I could have figured out how to bind a rx. It is so easy now.

If I had noticed the wire on the antenna before I opened the box I would have returned it.
