Review Atomic AD Stock

Atomic AD Stock Motor

• Brush hood is the same as Atomic AR30, PNWC33 and a few other motors as well. This means that brushes from PN also can be used.
• Brushes. This motor comes with copper brushes. Good performance for money, but it is recomended to use silver compound brushes.
• Can. The can is chrome plated, with a Atomic decal. No ventilation holes means that it gets a bit hot when you gear it hard.
• Cables. The cables are of good quality, but they could be more flexible. Length is good.
• Armature. The armature seems to be of good quality.
• Failure rate: Of a total number of 12 motors used, we have had three units that failed. One motor had loose magnets. One had defekt armature. The last one were shimmed to tight. 
• Solderings. The atomic brushes are chrome plated, and this means they are a bit hard to solder on. use a good quality flux and leaded solder to get the best soldering possible.

Performance:

This motor can be described as easy to drive. It has a very nice powerband. Very linear. The top speed is very good, but lacks a bit of torque compared to the PNWC33 motor.

It is one of the absolute most driveable motors out there. 

Even though it is a modified motor, it is safe to use on stock FET's on all mini-Z cars.

Preferred gearing at our track: 10 - 53 (64 pitch).

It is recomended to change the brushes to silver compound. These lasts a bit longer, and gives you a lot more performance. The con is that they are double the price as copper brushes.

Compared to:

PNWC33: Same brush hoods. PNWC has a littlebit more torque and motor brake. 

Atomic Stock-R: Not as driveable. More top end and more torque.
