Best value standard-size DL-series servos feature reliable 3-pole iron-core motors - they're the servo industry workhorse!

Rip Van Winkle, on returning to RC

30 years is a long time in the world of technology, and RC has been no exception in advancing at a rapid pace. This brief article endeavors to help bring you up to speed regarding what you've missed!

Outfitting a 30cc Ultra Stick with servos

A wide range of servos are suitable for this versatile model but getting the right one involves honestly evaluating yourself as a modeler to keep from farting away more than you should, or to be happy with your choice.

On using a gyro for rudder

If you've never flown a short coupled model equipped with a tail wheel, then it's quite likely you've never experienced the joy of taking off 90° to your initial heading. As pilots, we all know at some point take off includes a 'shoving the throttle forward' phase, and with the Pitts Special, a representation of the biplane popularized by designer Curtis Pitts, anything but perfect technique could mean a ground loop or a trip toward the weeds. Note; his 1943 design was considered revolutionary...

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.

Are you playin' checkers or chess?

Selecting servos can be confusing and most guys get snookered by expensive advertising campaigns and sponsored pilots who say what they're told to. How can you figure it out for yourself? We show you how!

How to use an HV-servo with a 6V-radio

A low-buck approach for how to use a HV servo with a 6V-radio system. Best part? It applies to an X-MAXX, TRX4 or pretty much 'any' vehicle (of any brand) relying on a 6V BEC-circuit to operate the steering servo!

When's the next super special sale?

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.

Servo choice affects your experience

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!

About RC servo motors

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).

How to determine flight time for a 2S1000 LiPo?

Is your avionics battery pack safe for three-flights? How about five? How can you figure out if it's safe to fly a sixth time before recharging the battery pack powering the radio system? The answer determines if you drive home happy at the end of the day, or not!

Let's gore an RF-ox!

Q. I'm curious what receivers and other electrical components you use, and maybe how you linked...

Silk and dope – demystifying modeling's classic finish!

What's the connection between servo selection, and a brief how-to regarding the classic silk-and-dope model airplane finish? As occasionally happens, we detour through the unexpected coincidences of life before reaching an answer.

Gasser throttle servo?

Which throttle servo would you recommend for a gasser? Many criticize using mini-servos in this application, can your mini servos take it? And because it's quite fast, what are your thoughts on using a tail rotor servo?

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.

Are ProModeler servos programmable?

A standalone servo programmer is something of a kludge because each servo must be removed from the airframe to access the lead, to disconnect it from the wiring harness and plug into the programmer. Rinse repeat for any adjustment - what a pain!.

Fear of loss, or how to stack the odds in your favor!

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.
