Storage how-to: fuselages
Over the course of +50 years, an elaborate system for storing models has evolved where inactive ones are hung from ceilings, and active models are stored in the workshop. We'll delve into fuselage storage, plus show what can go wrong and how we made a repair.
Understanding voltage loss
Back when 4.8V servos output 48-120oz-in, building a model requiring servo extensions once involved buying what was offered in the hobby shop. These days, when 8.4V servos output ranges to 1155oz-in there's more to it. Heads up!

Vibration kills servos
An engine box mounted throttle servo with a straight steel pushrod is about the worst thing you can do but it's what manufacturers supply because it's cheap and easy. We're going to discuss a better way to go about it.

avionics - selection
Hobby grade servos good enough? Consideration for these servo packages goes beyond weight, torque, speed, and price, so don't waste your time with this.

avionics - batteries
2-cell lithium batteries power most models. Do you rely on cells comprised of plastic bags to save weight, or rugged steel shells? Choose wisely!

When it comes to RF systems, guess what? We don't have 'religion' regarding brands (and helis don't care) but we do have a few thoughts.
