Beginners question

[jack]

How does the typical Mabuchi 550 motor fit into the motor classes "Stock" versus "Modified" and what qualifies as a stock motor versus a modofoed motor? :confused:

[Andrew the RC man]

1. the standard silver can motor cant hold its own to a modified.

2. modifieds will plain out say the number of turns it is and stocks usually dont.

also if your not sure what is stock and whats mod just post up in here and ask. most people can tell you

oops forgot to say. your standard 550 silver can is stock :o

How many turns would the typical silver kit motor then have-just to compare ? are they 30T, 27T

[Gabe]

ooh...
a 550 is a larger motor usually more toqurey...
540 size is "standard"
depending on the organization you race with they may allow the 550 if you come in dead last every time with it or if everyone else has one...
it is a great play motor...so is any old race motor...
"stock" is a generic term for a single strand turned 27 times around an armature.
"mod" is any thing else, lower turns=speed less toqure...
more strands=more toqure less speed...
it is a ballancing act with wire size,# of strands, and # of turns...
a 15single is a higher RPM motor than "stock" with less toqure
a 15double may not go as fast but may have more torque...
a tripple or quad wind is as high as most people will go...
a 8,7,6single IS as WILD as you can get YOU DON'T need these !!!
a 17-20 single or double is a good place to start if you NEED to start with Mod Motors...
now you need to know how to gear the new motor...the "stock motor" ratio is too high for some of these motors you need to let them "wind out" go faster let the motor do its thing, spin...or you WILL burn it out...

id say 30T, but im just guessing i mean the standard silver cans never say you just have to wing it. lets just say any motor more powerful that is proper geared would waste a silver can motor

[combones]

R U sure more strands don't equal more speed, less torque? 15T quad or quint = more rpm and less torque than 15T single or double?

Thanks for the info!!!! I guess before getting into some of those crazy motors, I will need a book to learn how to maintain them-any suggestions?

[XXXER]

Firstly, I do not care what anyone says, MODS WILL OUT TORQUE A STOCK ANY DAY. period. Your johnson silver is nowhere near the performer, hehe, though, if you picked up a stock motor, you will be more than pleasantly surprised, The Trinity P2K Pro, is one sweet stocker, and so is the Team Orion Chrome Stock RS(in Dyno tuned version).

A 15T Quint will have more RPMs, and less torque than a 15T quad.

A book? You do not really need a book, just go by in between cleanings, look at the commutator, and the brushes, and the bushings/bearings, clean your motor after every "Outing", or for the more persistant maintenance type, every pack. Get your motor rebuilt, by getting the comm cut, and the brushes replaced, after every 5 or so outings(varies with motor types, stock and mod, turns and winds, etc.)

I thought I crossed up something...
WHOOPS...
sorry...

I'm thinking about getting a mod motor for my RB. My electric is geared 17/82. What would be an ideal gearing for top speed with say a 15 turn motor? How about for quick acceleration? Thanks!

I have one of the entry level Tamiya stadium trucks (electric) with two sets of tires (off/on road) . Any suggestions on a good second kit (want to stay in electric for time being)- I was thinking HPI RS4 Sport as an on-road option and maybe the B3 Team updated as an off-road option. Seems the buggies have a reputation for breaking down a lot though ?

I thought a stock motor is 27 turns?

[gubbs3]

Most silver cans are 27t unless they say otherwise like the Traxxas stinger 20t. A competition stock like a P2K with greatly out do a 20t silver can because they are timed to 24 degrees and silver cans are 0 degrees. Don't worry about timing because it isn't adjustable on stocks. Mods do have adjust able timing but you shouldn't play with it unless you know what you're doing or you might fry it. Any mod will out do a stock. People might say that lower turn motors have less torque which is true, but you have to gear them down to avoid overheating them and to get all the power they have to offer. With the proper gearing on a mod, a lower turn motor will always be faster than a higher turn.

a lot of the kits have suggested pinion choices based on the motor-how reliable are they?
