GoPro in protective case

This is where most other designs get it wrong! Your GoPro is an expensive investment and to reduce damage it makes sense to install it in its protective case..doesn’t it? We think so! Therefore the Eaglet was designed to accommodate your GoPro with its protective case. The camera location provides clear obstruction free views for stunning FPV/video/photos and makes it easy to access and remove from the Eaglet. There is even an access channel from camera to payload area so you can connect your GoPro to your FPV gear.


Advanced aerodynamics for brilliant flight characteristics

The Eaglet is an innovative tail less design that takes the best features from conventional tailed aircraft and flying wing designs and fuse them into something special. The secret ingredient is the new aerofoil designed by ADR that is based on the well-known MH series foils that is popular in Europe. The problem with flying wings are that they do not have the stabilizers to correct for pitch. The Eaglet’s aerofoil is designed to have very minimal nose down pitching moment through a large range of flight conditions. What this means is that you need only a small amount of reflex on the elevons thereby minimizing drag! Also by mounting all the components inside the fuselage the airflow around the wing is undisturbed making it very efficient. On the Eaglet the wing is a wing! It is not a storage compartment.

We can go on about the thrust angle, wing incidence angle, wing tip washout, winglet design for locked in yaw, toe in angle etc. etc. but let’s just say it flies amazing and leave it at that. We have spent countless hours designing and flight testing many prototypes so the hard work has been done. You can just relax and have fun flying one of the best flying planes out there!


Compact design for easy transport and storage

Put it in a backpack, take it on a hike. Get that video you always wanted but could never get. The Eaglet features a unique wing mounting system with no servo wiring to connect. Designed to be compact and easy to transport/store yet quick and easy to setup. It can be flight ready in under a minute!


Plenty of space thanks to Double Decker Layout

We first tried the Double Decker Layout on the Wedgetail and liked it so much that we decided to implement it from the get go into the Eaglet. This layout is about having two separate fuselage zones: a lower compartment for power related gear, and an upper compartment for avionics. Both compartments are easily accessed through fully removable magnetic hatches. There is ample room inside the top bay for fully fledged autopilot systems to simple RC setups (340x75x25mm). No more messy tape to hold components in place, or ugly wing channels to hide wiring or store equipment. Your expensive gear is mounted securely and cleanly inside the payload bay.



The cavernous power compartment offers secure mounting of flight battery pack up to 220x65x35mm in size. No more squeezing of battery packs into cramped compartments! We tested it and it can easily fit a 3S 5200mAh and still have the correct CG. And it gets better! The CG location takes into account that not everyone wants to fly the same mission. You can fit a large or small battery pack and the Eaglet will balance correctly. Checking the balance is easy before every flight by visual inspection of the build in CG location markers. No more guessing or measuring from the leading edge required!


Effective cooling system

The use of NACA cooling ducts in combination with low pressure exhaust zones results in effective cooling of the power compartment components such as the flight battery, power module and ESC. The engine is cooled by a dedicated duct that directs cooling flow over it. Simple and effective!

Multi-Role platform: The Eaglet is for everyone

Whether you want a simple easy to use RC model or a stable high performance FPV platform the Eaglet can do it all. As a dedicated RC model it can cruise around or it can groove through the sky depending on how you set it up. As a FPV platform, install your choice of FPV gear (there are 2 allocated mounting points for video and telemetry transmitters), install a large capacity flight pack, and go to places where very few quadcopters can go.

Expand the capabilities of the Eaglet by installing a flight controller of your choice. We tested it with a Pixhawk and it transformed it into a very versatile UAV. Our configuration file for the Pixhawk setup will be available in the download tab above, and there is a lot of great information on Pixhawk/APM autopilot setups at diydrones.com

Designed and manufactured in Australia

The Eaglet is designed and manufactured in Brisbane, Australia. It is a typical Aussie product with a modern design focused around durability and functionality. The airframe is manufactured using modern CNC machinery ensuring a quality fit between components. We took a no compromise stand on the quality of the components. From the light but stiff carbon fibre wing spar to the slop free ball links, every component on the eaglet has been carefully selected and tested by us to ensure the best performance for all!

Versions

Available in 3 models in different levels of flight readiness. You can buy a kit and have fun building a well thought out design or you can buy a ready to fly version, it is up to you.


We are getting close to releasing the Eaglet at which point more detailed information about the 3 versions will be released, so please check back here soon!
