Red face New to the forum but not that new to RC world.

Hey everyone, Ive tried to look for a welcome thread but none found. But quick intro. Names bobby, age 30 and I live in Texas.. So excited to be back in the RC performance hobby again..

Ok so Ive recently got a early christmas gift from my Fiance` since shipping this year is crazy slow. She got me a RedCat Twister XTG Pro. Did some research on it before I picked it out and liked what I saw about it. Came with the new sport style 2.4 Ghz controller/ receiver and the heart of it all, the brushless system. Im not a big fan on the 2000 Ni-mah battery that came with it so I have ordered a 3800 2c Lipo 7.4v. Its on the way in the mail but im wondering if thats going to be good enough for my high speed addiction? Ive seen others doing some pretty beastly batteries on them, what would I need to look out for when thinking about upgrading to those higher grade batteries?

Welcome Bobby! Always good to get new people here.

Here is a very good "what you need to know" thread:
http://www.rcuniverse.com/forum/rc-c...ead-first.html

Real quick: Good you got a LiPo. NiMhs won't last long on a brushless system. Can't deliver the amps and get too hot. The thing you need to know about you car is if the ESC (and the fan, sometimes the fan cannot) can handle more than 2S LiPo. If so, then a 3S LiPo should get you all the speed you'd ever need and more for a 2wd 1/10th scale RC. I would highly suggest getting an infrared thermometer and monitor your motor and ESC temps. RTR (ready to run) cars tend to be over-geared, so if your motor is getting over 170F, a smaller pinion gear is in order. Normal operating temps should be around 140F or less for the motor and less than 100F for the ESC.

Yes you do have to shop around, and ask folks here what they like and where they buy. Do NOT be scared off from buying what some people refer to as "cheap Chinese Junk". Some of that "junk" is just as good if not better than more recognizable names. Case in point: HobbyPartz.com. I recently ordered an EXI servo from them for $15. I only got a couple packs thru it when I noticed it wasn't working right. Infant-mortality failure. I contacted them via their preferred method, a website where you can submit "trouble tickets" and told them of my failure. The next day I had a reply, "Very sorry for the inconvenience, sir. We will send out a replacement right away, free of charge. We will send an email when it ships. Note that the email will show typical charges, but be sure, we will not charge you." I got the replacement in four days. Other $15 servos I've gotten from them in the past are still working great. Got both of my brushless motor systems from them (EZrun 35Amp/4300kv WITH programming card) for under $80 each. Still going strong! Whereas a Castle Creations Sidewinder Sv2 system I paid $130 for from my LHS crapped out in three months.
