Maybe one of you can kind of create a guide on how "newbie" can make a wise decision on which one to get. Seems to me, there's some combos to follow
Well - as you said, there's a lot to it, but thankfully, I think a lot of the best products are already bubbling to the top, so it's not as confusing as it has been up to this point.
Here are my current recommendations for guys looking into BL and/or LiPo:
There are two real mainstream choices for controllers right now:
LRP TC Sphere - Excellent brushed and brushless performance, easy to set up, runs cool, generally works great
Novak GTB - Slightly "older school" than the new LRP, but still works great.
In general, I am recommending people pick a solid sensored BL controller from one of the big 2 right now. In the next year, there will be a ton of new products and there will be many more choices. Right now though, I wouldn't mess around too much with anything else.
On the motor front:
17.5T = Slightly slower than stock
13.5T = Slightly slower than 19T
10.5T = Slightly faster than 19T
5.5 = Fast mod for indoor TC
4.5 = Fast mod for outdoor TC
3.5 = Nitro killer
The big guns have started to pay attention to LiPo - companies that are making, or will soon be making ROAR-legal hardcased LiPo's include Trinity, SMC, TrakPower, Reedy, Tekin, and others.
In general, there is no industry standard rating for LiPo's right now. Companies often quote "C" ratings on the packs to indicate some sort of discharge potential but so far it's all basically bunk because nobody has explained how the "C" is measured officially. SMC has jumped out and provided actual 35A discharge numbers for their packs, which is more meaningful.
One of the biggest things with LiPo right now is fitment onto cars that weren't designed to accomodate them. For us, the RDX PHI is a particular challenge as most of the larger packs (4500 and up) are a bit too large to fit under the top deck. Thankfully, most companies have slim packs now (3200-4000mah usually) and those fit great.
The main thing on the LiPo front is that you'll want some sort of LiPo charger/balancer unit to maintain the packs. With that in place, maintenance is pretty basic. Don't overcharge, don't overdischarge, and keep them somewhere safe, and that's about it!
