There are certainly lots of choices today. I think first thing you have to decide is inrunner or outrunner. Inrunner, Hacker is your only real option.

For outrunner there are a lot more choices, from inexpensive to expensive.

Personally I use the Plettenberg Xtra 30-10 Evo motor, and Schulze 32.80KA controller. This is not a cheap way to go, its around similar price to the Hacker C50/Hacker esc. It is however the most reliable and best performing motor/esc combination for an outrunner and is specifically designed for F3A, so it works very well in this application.

For chargers the TP 1010C/210V combo is the best bang for the buck. Although the Schulze 7.32-12 is a new charger that is a little more powerful than the TP 1010, and has an integrated balancer. Its a lot more money but is a really high quality unit, with a lot more features.

I have both chargers, my 1010's serve as the workhorse to do the bulk of my charging, where I use the Schulze mainly for field charging as it can charge a 10s pack 20 minutes faster than the 1010.

For batteries, take your pick....tons of choices here, some good some not. Like Steve said, 4500-5000 mAh is your best bet for capacity.

Personally I still think the Thunder Power 5300's offer the best combination of performance, weight and proven longevity. Unfortunately, they are also the most expensive!
