I have both the Sphere Competition and GTB (and just a novak 4300 that I haved used with both). Both ESCs seem similar but I like the LRP more for a couple of reasons:

It is a bit smaller overall - slightly bigger footprint I guess though.
It automatically senses the change between brushed and brushless.
It has voltage cutoff for Lipo.
The wiring is a bit less complicated for using a brushed motor.

As a result Im going to be putting my GTB on ebay this weekend.

any more feedback comparing the two?

The Sphere seems to lack thermal shutdown for motors when they get too hot. Depending on your situation and your needs, this could either be a benefit or a drawback.

Comparing after markert service...I would choose Novak over LRP. Though I do admit that the LRP unit is more user friendly.

same as what or8tal said: advantages of LRP are the automatic sensor when you switch from brushed to brushless, and smaller size/footprint.

but novak after service is just 2nd to none especially locally (Voodoo: take note ). and since i dont really plan to switch much from BL to BR, i went with the Novak. but thats my situation .... and the gtb/3.5r combo is plain and simple -- INSANE fast!

as for the thermal issue, i think as long as you gear it properly then you wont have a problem with either one. i keep hearing people complain about thermal shut downs of the GTB but that just basically tells you that they aren't gearing it properly. to a certain extent, thats what i like about BL systems, it makes gearing a bit simpler since temp really dictates how high or low you can gear them to get the maximum output from them.

just my $0.02 worth ...

thanks for the inputs. i'm still pretty much racing spec (27t and eventually 19t). was just thinking that since the future will most probably be BL it would be a good idea to get one as early as now.

There's more to the heat issue than just gearing. There are al kinds of factors that can cause a motor to get too hot, including normal use, as the rotor will lose strength over time, and cause the motor to work harder to generate the same power. I've only seen BL motors burn up on the LRP where they wouldn't have burned up on the Novak since it shuts them down before they get hot enough to cause damage.

I've run both systems.

The LRP most certainly does thermal shutdown if needed. Luckily hasn't come up for me.

I had no problems with either brand so again, chose to stick with the LRP for size sake. And now with the 2007 and TC spec, there's more reason to go LRP.

I guess if you're hard on your speedos and the Novak service is better (I wouldn't know), then that could be the go.

Either way, brushless is cool.
