HELP! general inqiries about Factory Team b4!!!!!!!
Hey, everyone!
I have a few questions about my new Factory Team b4, but to start out with I'll give myself a small introduction.
Though I've been aware of and owned r/c vehicles for many years, just recently (for about a month now) I've gotten super intensly into the sport/hobby! I spend hours on the computer researching and researching and researching all about everything in reference to r/c that I possibly can, and I absolutely love it. It's basically a passion!
I bought a mini-lst a few years after it came out off of ebay, and it had terrible diffs. I blew my front, (didn't know this at the time) so I thought I broke it (haha) and set it in one of my dresser drawers for a real loooong time. Then one day I decided I should try to fix it. I'd been doing a lot of research on the computer and learned a bit more about the mini-lst and it's diff issues. So I messed with it a little, and found that my rear and center diffs were still intact. So I rigged the front outdrive on the center diff (locked it out of movement with a piece of thick wire) so it would work in 2wd. Though I know now that was a terrible, terrible idea, as the spiders would have to work 24/7 to get the car running, it actually worked for a while, then it "broke" (again). I took it completely apart one day, a 7 hour project, and individually cleaned and inspected each part, as to learn the vehicle. I proceeded to take the diffs out of their cases, and found that I had actually, literally, [I]melted[I] the spider gears in my center diff! Well, 2 out of the 3 haha! So then I actually found that both front and read diffs were intact, but the front gearbox was broken, (around the left outdrive) and that was why originally I believed it to be shot. But to the point... through all that, I was becoming more and more interested! So I was looking for a whole bunch of parts to hop up my lst, then found a completely hopped-up mini lst on ebay... C4 8000kv, 1-servo conversion, complete carbonfiber chassis, brushless esc, viscous diffs... everything!!! So I bought that, and have been running it for quite a while! I took it to the track and saw a ton of people rippin n runnin with buggies and stadium trucks... my cousin who also came along, and I decided that aside from my "cute little mini-lst" that these 1/10 rides were awesome. So I bought (amazing deal!) a factory team b4, a normal b4 that I believe comes with enough parts to convert it to a factory team, and some electronics out of a sc10, for only $237!!! I won the bid in the last 3 seconds (go me!) and there were a total of 32 bids. It was intense. I'm relatively young (17) and I had to have my mom pay for a good portion of it (I only had $160 haha) so I don't get the goods till I pay her back... but wanted to ask some questions!
(Sorry for that "introduction" being more of a short story. )
What kind of battery pack should I get for it?
Also, I plan on running it on a brushless system, I was planning on either getting the reedy brushless system, or the MMM. What are your suggestions?
I am solely familiar with lipo batteries, and I've only noticed mostly that people run b4's and cars that have the long tray battery holder-thing with nimh batteries. If I got nimh, what do I need to know about this like, cycling thing... & general charging guidlines?
Also, I'm planning on purchasing a thunder power multi-complatible charger for whateva batteries I'd be using.
That's all the questions I can think of right now...
Any other suggestions or comments on what I should do with my electronic-less FTb4, or anything regarding b4's at all? Anything would and will help!
THANKS SOOOOO MUCH!!!

Don't muck around with NiMh, almost everyone uses Lipo now, some just look like NiMh (barrel shape).
For 2wd off-road, it's hard to get a brushless set-up that won't work well. I'd go for something around a 13.5 to 10.5 sensored set-up to start with. More power than that is a handful for 2wd.

With a sensored system, I think I've read that it watches the motor, and that helps the esc respond better in terms of reaction? What are the actual benefits of a sensored system in comparison to a sensorless?

The sensor actually "sences" where the rotor is at start up and applies power to the apropriate pole. This results in a much smoother feel when starting out, after that the power is the same. Actually once running a sensorless system is said to be more efficient. Long story short a sensored system is a big plus in a buggy and especially for racing. Tekin RS actually uses both, senosored for start up and then switches to sensorless. If I understand it correctly.
