Introduction

Currently we have a conventional foam airframe and a correx flying wing. We also have an MQ-9 Reaper airframe, but it is too heavy to fly.

Chevron UAV

After a short interlude (I was in hospital for a bit) the 1.5x black Chevron UAV had some good flights. Below is a montage of some of them;

And here is one of a flight over my home town of Henfield;

Sadly this UAV is no longer with us (a bluetooth cable came loose while in flight and it crashed straight down into the ground under full power, went half a foot into the earth, quite impressive actually). But it lives on in our hearts and minds and most of the parts were recoverable.

Phoenix UAV

This is the next plane. 1.5x Mugi Evo design again. It also has a motor that spins 4 times as fast as the Chevron (HOLY SHIT). It's called the phoenix because I accidentally punctured a 5.5Ah battery while working on it, and burned a huge hole in it (from the ashes, etc). A second 5.5Ah battery caught fire later after I stupidly launched the plane knowing one of the servos was broken. It still kinda worked, but it didn't have the power to pull up, so the clever control loops compensated by pitching the whole plane down slightly, and it hit the ground at a very shallow angle. A carbon rod running up the side of the left wing snapped and punctured the battery AGAIN. I held the plane up so it melted through the nose and no other components were damaged. I've replaced the nose with the nose from the Chevron now, and will test when the new battery and servos arrive. This is kinda my blog now, I don't even live in London, lol.

Flying Wing

Wingspan: 90cm

Weight: 700g

Battery: 2200mAh

The flying wing is based on a Mugi Evo design, and is flown by an android phone (HTC One S). The phone uses its onboard sensors (accelerometer, gyro, and magnetometer) to determine the orientation of the aircraft, and controls the angle of the two elevons and the throttle over bluetooth via an arduino + bluetooth module.

Currently working on using the phone's GPS to fly to predetermined waypoints.

2x Flying Wing

A double-size Mugi Evo is in early stages of construction (1.6m wingspan) which could carry a payload such as a go-pro or other instruments. If you're interested in working on this or using the other airframes in a project please contact George or James.

Things that need to be done;

  • Finish the airframe and test it using a conventional radio controller
  • Re-trim the flaps and re-tune the control loops, using the smaller plane as a starting point
