DL-series servos feature reliable 3-pole ferrite core motors - they're the workhorse of the servo industry

There comes a time when servos with BLS (brushless) motors make perfect sense - experience teaches you when.

10lbs of force, or 160oz-in, is enough to fly giant scale model - unheard of in mini-size servos - in coreless and BLS.


Bypassing the BEC

Since the BEC included with the ESC is usually limited to 5A of current and modern high performance servos can exceed this, bypassing the BEC and using a 2S LiPo is an easy solution - and inexpensive too.

Fear of loss!

Marketing types push your buttons by using words like 'safety' to get you to ignore common sense and outfit your model with two battery packs. We explain why this is just BS designed to get rubes off their wallets.

Servo connectors & extensions

I occasionally field questions regarding servo connectors and extensions (especially for giant scale models). Let's briefly delve into some mechanical and electrical considerations because basically, we (all brands) play by similar rules.

The appeal of Hall Effect sensors

The best potentiometers are rated at a million cycles, but that's not forever so they're a wear item. And what about technologies like Hall Effect sensors? Learn a bit about the subject before your servos go to pot resulting in a crash.

DYK - how to care for LiPo packs?

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!

Worse than wasted motion?

At last, an easy way to eliminate wasted servo control-motion because of flight loads rocking the servo on the rubber vibration mounts.

Ubiquitous in the workshop

An essential workshop component, a common design defect comes from depending on foam weatherstrip to protect the fuselage surface - oops!

Move concrete blocks!

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

Servo secrets

There are three basic types of motor inside the servo. In order of desirability these are: brushed, coreless, and brushless. Learn more . . .
