Once you get your MSRX, come on over to the "official" MSRX thread and chat with us there:
more people will see your posts usually. RCGroups tends to have fewer random posts (unlike Helifreak.com and other forums) but instead tries to group all posts about a particular subject into a single thread. Thus, if you want to ask a question about something (DX6i, charger, MSRX) you can typically find the one "official" thread that has tons of posts and post your question there.
Good luck and happy flying!
