Default Mod motors and comm drops

Just started playing around with mod motors for the last couple of outdoor races and was wondering should you use comm drops with mod motors? This is in a touring car. Using a 10x2.

The arm got pretty beat up first weekend, had to skim 4 passes on it to clean it up. Need to work on the spring set up a little bit.

Thanks to all.

Drops will promote wear. Only use them if you're willing to cut your motor after each run. For stock you can get away with them for a little while....but I'm not a fan of drops.

from a rookie....freeze your motor (either compressed air(upside down), or ice) before comm drops..but as long as you have a lathe and few minutes between heats..comm drops are ok//but this is just a rookie talking

comm drops are an excellent wat to boost up your motor however you must be sure that your brush is of low silver content for it to work flawlessly. on brushes with a high silver content well i noticed that it made the motor weaker. the performance was not quite impressive anymore.

i also read from an r/c guru that you should never use comm drops on motors with high silver contend brushes installed.

A very small amount of tribo may help wear. Any other comm drops are going to wear the comm more then if you ran it dry. If you are running too much timing you'll have higher wear, try lower timing and higher gearing. Being smooth and braking very little will lower wear. Lastly it's a mod, high wear is normal unless your running a V2.

Very low wear. Check out the V2 thread for more info.

Why run comm drops in mod? If you need more power go to a hotter wind or maybe just increase the timing a little. In mod you arent limited to the performance of one wind and one timing setting.

Being new to mod wasn't sure if comm drops would help or hurt. By the sounds of it, you don't need it just work with the timing, springs, and gearing.

Thanks everyone.
