Default Brushless and LiPo

I got out of electric racing just before the brushless and lipo craze set in. I want to get back into electric racing again but do not know who makes good brushless motors or lipo batteries and chargers. Any suggestions?

Also, what do i have to do differently to set up the brushless and lipo components?

LiPos:
Orion, Core-RC, SMC, and Track Power have proven performance on the track. New the scene are the Reedy LiPo's.

Brushless Motors:
Novak, Speed Passion, LRP, Trinity, Orion, Hacker, Losi, etc..... All have pro's and con's.

As for setting up the components, its just like a brushed motor and NiMH battery. The only thing you need to do for LiPo is add a little weight to the battery since they are so much lighter than NiMH packs. Gearing a brushless motor is much different than Brushed. Follow the manufacturers recommendations for a starting point if racers at your local track don't have tips for you.

Default Chargers?

Will a regular nimh/nicad charger work or does it need a conversion? Or are there special chargers for lipos?

Do i have to discharge the lipos like the nimh/nicads or can i just top them off?

Are lipos legal for competition yet?

Lipo is approved by ROAR but local tracks may differ so talk to them about what they allow. Not all lipos are allowed. ROAR approves certain packs.

Yes a charger that does lipos (CC-CV charge) is needed.

I've been using the Novak Brushless/GTB combo and the Team Orion
Advantage charger/Platinum 4800 Lipo for the last three years, and
all I can say is, very reliable and lots of power!
Ask around in your LHS, I'm sure they'll guide you to the right direction.
Go Lipo/Brushless, no more discharging and no more cleaning. Just more playing time on the track!

A sensored system uses a hal sensor with a sensor wire going from the motor back to the esc to tell the esc where the rotor position is and when to commutate. The advantage to sensored is starting, especially in higher turn motors.

A sensorless system does not have a dedicated sensore wire going from the esc to the motor, but instead it uses the motors windings to let the esc know where everything is. The advantage is that you are not stuck with a "mechanical" type of setup telling the esc when to fire, but in a sensorless setup you can react and adjust as needed, so really it is a more efficient setup when you get moving.

Worth noting that with the new RS from Tekin you get the best of both worlds. A sensored start, then it switches to sensorless and uses the windings in the motor once you get moving.

Hope that helped a little.

Yes but gearing within motor types is different too based on brand and turns. As was mentioned above. Lots of these threads you created have been covered quite a bit before in the past. Might want to use search to see what you can find out there. There is a wealth of info over the last 2 years for brushless and lipo.
