I'm looking to get into sedan 13.5 racing and I'm wanting to know what's the best brushless system with a reasonable price. I'm not looking to running anything more than 2s lipo or anything faster than 13.5 so I don't need the most expensive speedo if it's not necessary to be competitive. I'll be running this on TC5r at West coast rc. what do you guys think about the Novak havoc systems?

Of course, we think the Havoc Spec systems are great...

Affordable, with plenty of on-board programming options. We also offer bargains in the Factory Re-manufactured area of our store.

The Havocs are OK, but i'd see how much space you have and check out the specs. A friend has one in his off roader and has no problem with it.
I use Tekin, but their gear is a bit pricier than some. In saying that, I have 4 of their ESC's and never had a single problem
Regardless of brand, use sensored for on-road touring, sensorless will cog like a bugger.
The key is really how competitive you want to be. If you just want to get track time and hone your skills, the Havoc will be fine. BUT, be under no illusion that all other things equal, the Havoc will not out-perform a Tekin RS Pro or LRP SPX or KO Propo BMC
