What is the smoothest ESC for offroad?
 

I'm hoping that 2010 will be a much more RC packed year than 2009 and with that in mind I've been looking at my equipment trying to work out what to change for the better.

Currently I have a Sphere TC in the 4wd and a Nosram Matrix 07 in the 2wd.

I am not overly happy with the smoothness of either, even on the lowest settings they don't seem anywhere near as progresive as my old Nosram brushed speedos.

I am looking at backing down a couple of winds on the motors too (5.5 in 4wd, 6.5 in 2wd going to 7.5 / 8.5 respectively as that I think better equates to the 12/14 turn brushed motors I used to run).

What I would like to know is what speedos people are impressed by in terms of smoothness, especially from those people who have run several different brushless ESCs.

If anybody has any constructive comment regarding motor selection I'd like to hear those too.

What I am most interested in is smoothness and progresiveness as I am still very much struggling to adapt to the brushless set-ups I have.

in before everyone else with...

SPEED PASSION! :thumbsup:

speed passion again best we have run so far

Rog,

A lot has to do with the rotors in brushless motors IMHO. What motors/rotors are you using?

I must say it was the Speed Passion range that had caught my eye!

Any more from anybody else?

Northy, tried the following all with the supplied rotors

Novak R & L
Orion
Nosram & LRP (bonded and sintered)
Speed Passion (which seemed the smoothest to be honest but it was a mild wind @ 8.5)

All still seem a little too agressive which is why I was asking about speedos first....

Aggressive where? Bottom end? :confused: If so, a smaller rotor will smooth bottom end out, and increase top end - win win imho ;)

I'm running the SP GT2.0 LPF with their V3.0 5.5T motor and it seems to have loads of get up and go throughout the rev band and you can tootle along at 'pit lane speeds' (hehe) easily

I'd say speed passion too rog, the 3.0 motor are super smoooooooooth. Easy to setup speedo's too!:thumbsup:

What batteries are you using? Lipo,s or nihm

NiMh .. well over a season old too (but still going strong with good numbers on the Spintec).

Not even considering LiPo until I've got the speedo / motor issues sorted.

Interesting there have been no "anti" Speed Passion posts so far

Keep the info coming please guys.

One more for Speed Passion! :thumbsup: I've tried pretty much everything...

The "programming card" is also a big bonus! Very quick & simple for setting up the ESC!

Smooth bottom end!

The tekin RS pro has a current limit option to really turn down the power, and custom throttle profiles to smooth up the throttle response. The duel mode which switches from sensored to sensorless when the motor starts up also makes the drive smooth.
They are expensive new especially considering you need the hotwire as well, you could do to find someone selling a second hand one, with the pc linkup hotwire really - Like me - MUHAHAHAHA:lol:
(seriously PM me if interested!!)

It really depends on the rotors you were using in your motors.

LRP/Nosram X11's came with 14mm out of the box, which always gave a lot of torque. The 12.5mm or the 13mm gave way better drivability.

I have Speedpassions as well and find them great with very fine response on the bottom end but was always able to find good settings with the Sphere/Matrix speedos when I still had them.

The handeld programmer is nice to use mind and if you're feeling like something new you could do a lot worse then the Speedpassion range.

+1 , :thumbsup:

Speed Passion is in the best you can get right now for sure

I'd have to say the Orion Vortex Race Spec, although the manual is rubbish and there are limited setups built into the ESC unless you have the ICS usb adapter.

What are peoples thoughts 12 months on?

speed passion still

The Novak Kinetic is good. Big improvement over the older Novaks.

The Nova-link software makes it really easy to tune the speedo and to save speedo setting for future use.
