Buying into the marketing-driven idea of special pricing, as if costs change based on certain magical days, is a good start! Instead of cat and mouse games, we make you our best offer from the very beginning.

Interested in trying your hand at 3D? Confused by conflicting advice regarding servos? We help guide you through specs like torque, speed, current, and voltage - and why they matter. Plus what's better for you; a BEC or battery - and why!

Ever wondered about the difference between DC, coreless, and brushless servo-motors? This askJOHN article addresses it in a largely brand neutral way. and is generically useful because all servos - regardless of brand - use one of these three types of motors (share the link freely).

The best potentiometers are rated at a million cycles while electronic Hall Effect sensors have a theoretical unlimited lifespan. This means pots are wear items. Does this make magnetic sensor technology a no-brainer? Not so quick!

We field a lot of questions regarding the splines on our servos. Below are examples and their answers. And if you're too busy to read this, then we'll cut to the chase with a TLDR; ProModeler servos...

Learn how a simple chart for measuring the at rest voltage of a LiPo battery pack helps determine the state of charge, or remaining capacity. The best part? It's both easy and free!

Background: ProModeler servos are rated at 7.4V (nominal voltage for a 2S LiPo pack under load), However, it's widely known that fresh off a charge, the output of a 2S LiPo may approach 8.4V. Thus,...

Selecting servos for a 118" wingspan Extra 260 powered by 150cc engine, is no laughing matter. When a District 7 IMAC-pilot reports . . . (more)

Despite using 13 o-rings in our standard size servos - more than anybody else in the industry - If you're going to play submarine with them, you should consider taking additional precautions against...
