| You can't go wrong with Astro flight! Motors and gearbox's are all bulletproof in design. Efficiencies are very high. Astro was ahead of the pack with top quality motors well before any of the Johny-come-lately. You'll pay a little more for an Astro but you'll find you often get what you pay for.

Personal note from Dave. Getting this book was one of the key moments in my electric flight hobby. Here are the nuggests of truth and wisdom to help you begin to understand how to setup your e-motor systems. What is Watts, KV, how does gear ratio or prop effect amps? Get a good foundation here as I did many years ago. Even though this text was written in the brushed motor days, all the principles apply. And, understanding these simple principles is what gives you the power to understand and figure out many of your motor setups or what they need to work well.
*SORRY! Book is currently out of print. Please check web site at a later date for future updates as we're hoping they will reprint or republish in another format ;-).Send us an email to davthacker@aol.com if you want email notification when or if it becomes available again, thanks!
