Please don't delete the thread. I can't offer any help as I'm just getting back into rc and brushless motors are new to me. The info is helpful.

Too bad you don't have any info on the TP Z3R-S. I'm running that motor, and all I know is that it has a lot to give.

Ive searched every motor on that list, and what I have found is on the list, and its not much. I wish manufacturers would give more info with a motor. Maybe the info is supplied with instructions with the motors. I dont know?
Thats why I was hopping others who have bought any of these motors would be able to fill in the blanks.

Some of those motors are over 100 bucks. Personally, I wont put out a dime for a motor unless I know at least what turn and kv it is at a minimum.

Good call for someone that seems to know alot..... Mate have a think thats why there are governing bodies to approve these motors and everything we use...
There is no reason to sell a motor or anything with all the specs as they give you what you need to know to use it.... Thats there business so thats their edge over there competition.... Dont whinge.

I am guessing you dont even race you just bash around a backyard and want the numbers to be better than your mates yeah ???

Yeah we all know that governing bodies around the world are always right and know everything huh?

Why have a thought for myself when someone else can do it for me.

I am beginning to race, and want to know what im getting for the money I spend. As you can see in the list of motors kv ratings range from 1900-2700. Maybe more without having the specs for all the motors.

Depending on track size, weight of car, gearing, and Im sure more. The kv ratings could be the differance between 1st, and going home to order more parts. May not make me better than my mates. It will make me more informed.

I tried to do the same thing years ago and found manufactures numbers don't mean much. If you really want to pick an all around good motor find out what the fast locals are using.

From what i've seen at big races for 17.5 classes these are the top 4 motors, for proof check out this website www.rcprogear.com

- Epic DUO3 (could be aliased under numerous hobby shop names as there the biggest OEM motor on the market today) easy to adjust timing.

- Novak Ballistic, great motor, easy to adjust timing.

- Speedpassion V3, for no-timing class you will need the 10 or 20deg sensor board option as the stock motor does not provide enough adjustment.

- LRP X12, need to replace insert to adjust timing.

Of these motors I think the DUO3 is the lowest cost and a great motor. Prior to the DUO3, there was the DUO2 which was very inconsistent you could get a good or a really bad one, before that and probably the best BL motor made was the DUO1 unfortunately you can't buy this motor anymore. Luckily EPIC found the formula again with the DUO3.

So don't get stuck on this spec junk it really does not help.

KBorg, don't get hung up on the kV, it's only one parameter, and not a particularly useful one. Power output is more useful, as it's a baseline for how much current the motor can pull, and therefore how much you can gear up.
But, as others have said, these figures are often "economised", and not great on their own. THe two best ways of getting the best performer is to either buy them and try them (most expensive way), or talk to the fast guys at the club as they have probably already done that (smartest way).
