Questions?? Stock vs Mod

Hello,

My understanding is that 10 Scale racing has two major categories: Stock and Mod.
- What are their main differences?
- Is stock one category, or are there sub-sets for each motor rating (ie, 21.5T 17.5T, 13.5T, etc)?
- If a motor has a Kv rating as opposed to Turns, in which category does it race?
- Which category do you prefer and why?

Many thx

Stock 2wd buggy is 17.5
Stock 4wd buggy and 2wd stadium have been 13.5 lately
Stock 2wd short course is 17.5 but many tracks are going 13.5
4wd short course uses 1/8 scale motors, Kv rated. I believe it's generally an open class

all stock classes are blinky. Stock racers tend to go for light weight and low rolling resistance, as well as getting battery internal resistance as low as possible.

Mod is any turn motor, and ESC timing is allowed. Weight, rolling resistance and batteries tend to matter less than in stock, but accelerated wear on everything is a draw back.

I race stock because I can't drive well enough to handle mod, and stock tends to be more popular.

Stock is using a motor and ESC by the rules. That can be a one model motor or one from a list. Most of the time a blinky ESC is needed or just one model ESC (like ETS rules). With new devellopments it could be that an ESC with a RPM limiter is needed.

Mod is simply everything is alowed as long the dimensions are within the rules.

Regarding Kv, if you are talking about 1/10 motors then there is a high chance that those motors are not alowed. Kv ratings are most of the time specified on sensorless motors which are not listed in any stoc/spec class.

With 1/8 electric then yes, there are rules about a max Kv rating because all those motors are specified in Kv.

If the only motor you have is kv rated, then you can run novice or mod. Start with novice, then try to pick up a cheap used 17.5 from someone at your track when you start thinking about stock.

stock is slower class because you must not run any timing advance in the esc and you must run a slower motor. Most stock 2wd buggy must run a 17.5 turn motor and 4wd buggy run a 13.5 motor and on road touring cars run 21.5 motors. mod is a much much faster because you can run any motor and any amount of timing in the esc. Stock generally is more competitive and usually much more popular generally because mod is very hard to drive.

Mod usually means more money and more mechanic time.

It is just what the club or competition has stated, in Europe a 10.5 or a 13.5 turn motor with a blinky ESC is much used for onroad touring.

Most drivers disagree with you. With stock to get an advance you need to have the best. People do buy 10 motor/esc combo's and test all possibillities to pick out the fastest combination. Also they have the need to replace all bearings by ceramics, buy low friction pulleys, the best batteries etc.

While with mod all those things have a less influence on the total performance.

For fair racing I prefer mod, driving skill decides the winner. Stock is good for scale speed and realistic racing, but mostly creative engineering skill decides the winner if tech is not strict
