Hello all,

Just purchased a new t-rex 450. I have a JR 9303. My local shops do not have any Rx in stock. Which rx do u all recommend for the 450 for my JR. Thx.

I am sure I will have many more questions since this is my first electric.

The 790 PCM RX works great in a Rex. They also have a new lightweight version.

I use a JR R770S PCM receiver with my JR 6102 TX on my T-Rex 450SA. It works great and I’ve never had a lock-out or glitch.

Ran 770's before switching to spektrum. Worked great. Check the classifieds there are tons of people off loading there 72mhz stuff for cheap. If used isn't what you want grandrc is great to work with and that UL 790 looks perfect. You may want to stick with the 770 or 790 so you can use it in bigger birds later on. I ran 770's in my raptor50 as well.

Thanks guys, I will be ordering one soon.

Now a new question.

I am just starting the build. It is a SE V2. I am starting the flybar assembly and the flybar seems really lose in the head. I have yet to set the set screws, but it just seems like there is a lot of play in the flybar going through the assembly. In my nitros, the flybar is more snug sliding through the head. (does this make nay since?)

Just seems like the flybar is to "thin"
