I DONT WANT TO CHEAP OUT BUT !!!

[janus_77]

EC power also sells a sensored set for 81 pounds with free shipping. Motor is not BRCA legal though.

1.) The 60A version I have does (options are 'off', and 2.6 - 3.4V/cell in 0.2V steps)
2.) Yep

Incidentally, the 60A esc seems happy running a Reedy sensored motor too (without sensor wire, obviously) with no cogging etc (so far).

1.) even the 25A + 35A versions do.

1- you can set the lipo cut off on the ezrun systems from 3.0v per cell up to 3.4v per cell to protect your batterys (you can actually set it from 2.6v per cell but i dont really know why you would go this low? - anyone know?)

2- standard size for pinions

It may be because on some ESC's there is no allowance for a very short dip in the voltage - for example when you apply full throttle on a high grip track.
In cases like this the better ESC's recognise this as the voltage immediately rises and the ESC will operate as normal. Some will not recognise this and shut down as a safety measure, which can be frustating.
I know some drivers who have had this problem and run their ESC on Nimh mode rather than Lipo to stop this happening. They NEVER EVER run the battery down to anywhere near the limit as a precaution to ensure the nominal voltage is always higher than 6v

It may be a reason for putting the cut off down to 2.6V.

However, I repeat you must NOT run the battery down to below 6V under normal running

swayze08,

Why not a brushed ESC & motor. You would get outstanding top end stuff for very very cheap.

Brushless is a bit a fashion thing (I am a victim I know)

Brushless only advantage is the motor maintenance, but it is only valid for high power motor. Besides, the efficiency is much better on the ESC (the ESC doesn't need a heatsink & fan for heat produced), and equal efficiency on the motor for reasonable power motors (contrary to what some manufacturer's marketing pretends).

Try a brushed ESC + motor for (10£+2£) ... see trader corner on this site. You'll see later if you feel the requirement for brushless...

You are joking

As a long time advocate of brushed/nimh I recently changed to lipo/brushless and would recommend it anyone.

No more skimming, changing brushes - easier to get the right ratios.

At the club more equal racing now just about everbody is running brushless.

Oh yes I run 13.5 changed from 27T/19T hardly high power and the benefits still stand

[chb]

As I said, the benefits are real for <13Turns brushed sure. The reason being that the cummutator suffers at that current going through, but above that it's OK

BR=(14x2T,19T + cyclone TC) BL(LRP3.5T LRP4.5T novak5.5T + GTB & sphere)
I run both and no I am not joking...

Brushed motor well maintained doesn't go wrong easily.

they are standard shaft, they also have lipo cutoff, with the ability to vary the cutoff voltage with the programming card.

i have been runnning the 9t ez run combo for about 6 months now and it hasnt missed a beat, they seem like really good quality, coming prewired with gold 4mm connectors on motor they are also easy to install and set up. only criticism i can make is throttle can be a bit harsh at low speeds, but this is the same for all sensorless brushless systems. one of my friends bought an exelorin system at same time as i bought the ez run, he is now on his third esc.

would like to know why budget systems like this arent on the brca list, they should be, even if is was just for f3 or f4 drivers

Unfortunately the Ezrun will never be on the BRCA approved list. Not for any technical reason as I'm sure it complies with the rules just as well as the few sensorless systems that are legal (and there are some).

No, it will never be approved because in order to be approved it must first be submitted to the BRCA for approval. Thats normally the job of the distributor and since the Hobbywing doesn't have one in the UK, and even if they did their contract with Speedpassion prohibits them selling Ezruns here that is never going to happen.

Daft but there it is.

Of course its only the motor that needs to be approved. So just buy a cheap, used motor off the list and run that without the sensor wires.......
