hpi blitz christmas present needs a brushless system

Hey guys, I just got an HPI Blitz rtr. Brushed. I've been reading up on systems and have come to the conclusion that a castle mamba max is going to run me 150 + . I read somewhere that a lower kv is actually better because it increases torque. But mostly I'm just confused by all the brushless lingo. Can I get some help picking one? Price range goes from free to about 150. running 2s lipos from Dave on the track. Not bashing this sweet truck. Thanks. Hope to make it to ep when the weathers not bad.

*** Adding this in: this is in terms of 2WD 1/10th applications and not 4 POLE motors which are typically run in 4wd applications.

Almost all 540 can brushless motors have similar torque unlike brushed motors. The torque in brushless motors depends on the diameter of the rotor and strength of the magnet on the rotor when comparing apples to apples ie: not 550 can or 4 pole and batteries excluded. I think in large the lower kv(higher turn sensored) motors and sensored are significantly smoother in racing applications. Lower kv will also yeild longer run times. Unsensored systems are more efficient, but less smooth at lower speeds. Some ESCs run dual mode which is sensored at low RPM then sensorless at higher.

First thing you have to decide is budget. That will decide if you get an ESC that has "boost" or not and or computer based programablility.

From there if racing I'd go with something sensored. In that respect you'll want to get one of 3 motors, a 17.5, 13.5, or 10.5. 17.5 will only be good in racing situations if you get an ESC capable of boost if going to race in ELP. 17.5 will also allow you to run in stock classes in other areas. 13.5 seems to be the sweet spot for most, and 10.5 for others in ELP. MOST motors are going to be about the same so just pick one and again this depends on budget.

Systems I would recommend:
Tekin RS
Mamba Max Pro
SpeedPassion 2.1
Hobbywing 60 or 120A(same as speedpassion just cheaper )

Motors:
Tekin
Novak
Murfdogg
Trinity D3
speed passion/hobbywing.

Again this all depends on budget.

The Mamba Max Pro is probably the most flexible ESC on the market. It can run 2S to 6S and will even run 8th scale motors, computer programable, has boost. The only draw back to them is if you have a good servo or are running a non 540 can motor you need to run a glitch capacitor or separate BEC. Even the mamba monster max with a hungry servo needs a glitch cap.

I think if you asked around here Tekin RS would be the resounding answer for racing applications.

Hope that helps... or confuses things ask away.

Thanks Dave, that helps a lot. I can fudge the budget a little because of the increased income due to the holidays. >

Price wise, there's a guy with a brand new Mamba Max system for 160. Is that better than the tekin rs? The lowest I can find for an rs is 220 used. Thanks
