The right pack can make or break the experience so we show you three easy ways to go about doing it the way pros do; by chemistry and capacity!

Using the stock TF-50 2.4GHz FHSS Digital RC System with a powerful HV servo requires a power source that's up to the job 'and' which won't burn out the radio. We show you how!

Paying for performance you can't feel is the height of foolishness but many club pilots do just that in equipping their model as if they were the 2nd coming of Jase. But if you tell us straight how you really fly then we can help guide you to the right servo for your purposes.

Flex Innovations does a fantastic job of packaging the CAP 232EX with servos great for the purpose of hitting an unbeatable price. Pilots who love the airframe and outgrow the servos have four ProModeler alternatives in the mini-class, one of which is probably just what's the doctor ordered!

Ever wondered how such a tiny motor can produce such huge amounts of torque? Like the transmission in a Ferrari launching it to to 200mph, with the servo it's down to the gear train.

There are a class of servos, which we call tail rotor servos. Their pulse range is half . . . click to read more....

You crashed your model because the ESC failed, which took out the BEC also. With a dedicated pack . . . click to read more....

Most charger-purchases are tactical decisions; what do I need right now? But a more strategic view may result in your deciding several inexpensive individual chargers deliver better redundancy and flexibility for charging/discharging several packs at a time. This may better suit you!

Selecting servos for your next 60-class 3D model from Extreme Flight is either a matter of doing what others say, or thoughtfully deciding whether - for your style - you prefer speed, power, or both!

Selecting the best steering servo for a big fast competition buggy like the TEKNO EB48 2.0 isn't a slam dunk decision. They suggest 300oz-in but the decision is more complicated. What's best? Depends.

Most only think of the Y-harness for connecting two servos to one channel. Thing is, this handy little accessory is useful the other way around, also.

In the vein of a penny saved is a penny earned, this brief how-to shows you an easy way for making your mask serviceable for its intended duty after repeated use. Maybe it's a stretch to say it results in a free mask, but it's effectively true!

Watching some rat bastard politician on TV was the first we noticed someone wearing two filters. One with their party's logo worn over a serious N95 led us to think; 'If it's good enough for them...'

Figuring out how many cells to use for the control avionics battery pack depends on both the chemistry - and - what it is you're trying to do. Whether it's 2-cells, 4 in series/parallel, or 7 in series, the math is easy and we show you how!

Frank Tiano should have promoter on his gravestone. He was good at it. And not just for his business, but for the sport, too because three events he initially conceived to benefit his ZAP line of adhesives grew to become honest to God model aviation happenings, Top Gun, Florida Jets, and 12 O'clock High!

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!

Reports of trouble in paradise may give pause but this brief guide shows how to address reported shortfalls while select the best servos for your expectations in 3 easy steps.

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.
