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!

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 performance comes by feeding the servo the highest voltage for which they're rated, 8.4V but getting there can be tricky. We look at several ways of skinning this cat.

One of modelings premier engine men, and approaching 100 years on this Earth, Clarence Lee became an icon of the sport - and is revered - for freely sharing hard won wisdom regarding model engines, their care, and handling. This profile touches on one of his creations, the Lee Custom .61 as serially produced by K&B.

A wide range of servos are suitable for this versatile Hangar 9 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.

Aservo that's perfectly adequate torque-wise for the size of the control surface and anticipated loads for this splendid sport model 'also' needs to be up to snuff speed-wise when it's gyro-coupled...

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!

What we think of as a radio control system for models can be broken down into several sub-systems. Servos are part of the control-loop sub-system. The transmitter and receiver are . . . click to read...

Why do some brands of digital servos hum and squeal while others don't? And are the ones making so much noise also pulling more current? Click to read more....

Ready to spend $700-800 on servos? Worried about making a mistake? Would you like to discover how to select the right servo for 'you' and at the same time maybe save big money?

A question that comes up fairly often regards compatibility between various brands of receivers and ProModeler servos and the short answer is yes, they're compatible because of PWM, the universal standard.

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.

Both old fashioned plywood and commercial foam stands suffer a few problems. A big one being reliance on sticky-back foam weatherstrip at the saddle that fails over time because the foam deteriorates...

A dead throttle servo is an, 'Oh shit!' moment for many modelers. Thing is, if you follow best practice, it's nearly a non-event. We show you how to set up your servo and linkages to avoid damage due to engine vibration and heat.
