I found these on e-bay and bought a set. Nice bearings.

if you reread my post you will see i was referring to the KD magnets being weak after a few runs,not the orion.the orion is efficient and runs good also but it is not as fast or faster than the KD.it is not physically possible unless you get a real bad KD.this is the point i was trying to make.all the motors you named are good motors.i really dont like the c2 but i have seen a few good ones now and then.

The Orion/Peak/Reedy/Integy/Atlas/CheckPoint 19's are all hemi winds and have 1/2 turn less copper on them than the KD and C2. They have the potential to turn more RPM...but they dont because they have much stronger magnets. They do produce more torque so you can get them way taller.

In sedans they are all much faster than Trinity 19's. In 1/12th I thought the stronger magnets might be negative for efficiency but it didnt work that way. I am fairly sure they are all faster that the Komodo when geared right.

I guess we will find out for sure on the 26th :sneaky:

yes we will.the KD has less wire on the arm than the C2 and also less than the hemi wound chameleon from what i have been told.the magnets on the orion are strong but the KD are when they are new.when the magnets fade on the KD,thats when the motor falls off.every KD i have has dropped in RPM after the magnets dropped off as did the tourqe.i will check on the actual weight difference between the arms but the KD arm is alot lighter than the orion which is the reason for the high rpm and less tourqe.tall gearing does not always mean faster motor.the KD is very difficult to hit gearing on but when you do it is insane.just remember when we were checking motors at joes.23500 RPM is weak compared to what i am getting out of em now.i have 3 doing 27000-29000.you dont want none of this sucka. :lol:

and adrian,NO ONE could touch my KD at Minreg in my touring car.fresh motor before mags dropped.i was accused of running a mod arm in that motor by everyone including PW,dobbs,butter,art,steve or whoever saw it run.no orion,checkpoint or whatever was as fast that day.

this is straight from the late big jim




The common belief that a Hemi wound armature is equal to 1/2 turn less is an old-wives tale or an "R/C Urban Legend". The fact is that the Voltaic Principle states that in order to make a magnet loop of maximum strength a coil of wire must cross itself when wound around an iron core. Since the last turn of a Hemi wound armature coil does not cross itself, it's believed that it's equal to a half turn less. This is ludicris!

Since it's impossible to make an armature with only 1/2 a turn of wire less of the total, no one can say what is equal to that, since no one has made one.
If one were to take the last coil off of a Hemi wound armature and the last coil of a Mabuchi cross-wrapped armature and measure them they would find that the difference in length is something much shorter than 1/2 turn around the stacks.

So I wonder what basis that person used (who made this up) to determin that a Hemi wound armature is equal to 1/2 less?

Big jim was right about a lot of stuff and was wrong about a lot of stuff (but he would never admit that :lol: ). He swore the Reedy MVP was the best stock motor ever :rolleyes: ...until he stopped working for Reedy.

Every mod BR motor is hemi. Why? Because that form of winding yeilds a faster motor.

This is all academic untill we test it on a track.

oh,i agree 100 %.hemi wound is faster as long as all conditions are equal.these are different conditions.lighter arm and more narrow webbing.

just so everyone knows,adrian and i are good buds and we talk about this kind of stuff all the time.we are not flaming or arguing with each other.just normal conversation. :lol:

Yup... :nod:

but my car is still faster :lol:

Yes, we know you guys are friends. But a little flaming would be more entertaining for the rest of us! :D :nod: :D

ok,

Adrian is a punk and went to a culture club concert.he rushed the stage and got slapped by boy george!!!!!!!! :lol:

TOASTY!! :lol:

i have been using the K19 at a track that runs a nitro sedan class and a 19T class twice against reedy 19quads, trinity D5 with timing cranked, checkpoint money 19's and have dominated hands down on speed. each time having my car looked at and a barage of questions.

on a huge track 2 weeks ago in the main i out qualed 2nd by 3 aps with 42 and went 44 in the main to win. BTW winner of the nitro class won with 39. needless to say my car was looked at again with lots of questions. from the electric and gas guys.

the track i raced at doesn't allow any winds below 19t. (think they do that on purpose) they told once when i first showed that sometimes the electrics come close or match the laps of a gas sedan, they boast that gas is the fastest way to go....i have been killing that bragadatio fast.

theres nothing like woopin up on the gas guys. :nod: nice run buddy :nod:
