electric question - AddictedtoNITRO - 07-30-2006
Hi guys I got a couple q's.
First off let me say that I am pretty new to the whole rc hobby maybe a year in. I have a T-maxx w/force .15 bb, A nitro Evader st stock .18, Mrp outrageous drag boat w/ 19t mod motor and novak esc, and now a losi jrx-t. My q's are I picked up a reedy 9t motor thats like new. I put it in with my novak and it runs for like 15 sec and quits. Pretty sure esc's not powerfull enough for it. what is a good cheap esc for this motor? Also how do I run for more than 4 freakin minuits. I have 1500 batts. How much more will I get if i get some 3300 or 3800's? Finally as you cam tell I'm going pretty cheap with my stuff. I buy stock replacements when I break. I'm saving my money for a zenoah powered 50" forabuck Project. I like to drive my stuff but this electric stuff is really frying me. lol
Any help would be appreciated also if you got something I need let me know
Thanks

wow those are more than I paid for the whole truck.
This is gonna suck
Any recomendations on a fast ass motor that I could use with a 15 turn esc?

Trinity Cobalt motors get good reviews but be prepared, good motors aren't cheap either.

Hey bud, I got a brand new, never seen a charge 3600 nimh pack. Yours for $15 shipped.
electric question - AddictedtoNITRO - 07-30-2006
sold
electric question - thenewguy821 - 07-30-2006
You could also go with the Novak Super rooster ESC. It also has no motor limit. Generally, when buying an ESC, get a lower motor limit than you plan to use. IF using a 9t motor, you would probably have to get a "No limit" ESC.

15T Trinity Speed Gem "Titanite" rips for a 15T motor

Forgot what it actually meant but it has to deal with torque. The more winds the more torque. If somebody says they have a 12x2 motor, that means a 12 turn, 2 wind motor.
electric question - DAVEC-NITRO-RS4 - 07-31-2006
Good article about motor winds in one of the two mags I get this month (XRC or RCCA). It's how many strands of wire are wound around the armature, and how many times. I'll see if I can find the info online and link to it.

thanks maybe if i understand this stuff more i'll be better at making them

thanks lots of good info in there guess I should look harder.
electric question - Tex - 08-01-2006
revo2k, you got that bassackwards......the lower the turn, the more power and the lower the wind the more torque you have.
so a 12x3 will be faster than a 15x1 but the 15x1 will have more torque
electric question - ghosty - 08-01-2006
actually a 15x1 will not have more torque than a 12x3 a 12 is still a 12, 15 still a 15 but a 15x1 against a 15x3 the 15x1 will have more torque but the 15x3 will have more top end and be easier to drive.
electric question - Tex - 08-02-2006
I was on the right path ....lol
electric question - ghosty - 08-02-2006
yep kinda.lol
electric question - AddictedtoNITRO - 08-02-2006
ok thanks for the info I actually found out the mortor is a 15t triple so thats pretty good for speed bashing right? My esc will handle to a 15t so it will work but gets hot pretty fast can't do back to back or it twitches is this normal?
electric question - ghosty - 08-02-2006
did you gear down for the lower wind motor? if not than that could be your problem also a lower wind motor will get hotter faster than a stock motor aka 27t
electric question - Toughtrax - 08-02-2006
A 12X2 would be it takes the armeture 12 rotations in the can to make the rear wheels to turn 360 deg 2 times if I remember correctly.
As far as motors go I would strongly suggest looking into a 19t, they are very strong motors and will give you good run time on some 3600's most likely a little over 6 1/2 min depending on how old the cells are and how many times the have been cycled.
For gearing if you just went and picked up a 18, 19 and 20 tooth pinion gear you should be set for just about anything, as far as bashin with it the motor wont be a silly fast one but it will be a safe good reliable motor that you wont have to worry about the brush going bad after 25 runs or so and the arm will stay nice and tru.

um no a 12x2 actually means the wire goes twelve times around the armeture segment with 2 strands of wire

No your kidding ghosty, yes I do know that sorry I was thinking of rollout its been a few years since I had to think of electric stuff.
So for all of us that need a little refresher here is a nice little thing I found about electric motors.
