Helicopter UAV Tests: Blade CP+
I've logged approximately 15 flights so far this Winter since I got the thing. I've also been practicing a lot with the simulator (Realflight G4) for forward flight.
A few of my most recent flights have included the onboard wireless video camera. I'll post the latest one as soon as its available! Unfortunately, with the symmetrical blades, it small helicopter doesn't have enough 'umph' to fly outside of ground effect while carrying the camera payload. I should be able to improve this by using some flight-bottom rotor blades and my lighter camera/tx combo which is currently permanently mounted inside the EasyStar. I also plan on doing the Brushless Motor upgrade in the future.

Aftermath of a Crash: Crashtermath
Well, I thought it would be a good idea to get my Raptor 30 helicopter tuned up and running again. Found a nice guy out at the flying club (www.crskyhawks.org) who got the thing setup correctly. Ended up running three tanks of gas through it while trying to hover, accidently landed with a 'bit' too much left to right 'slide'. Main rotor kissed the ground and a 'pieces-of-helicopter-fountain' materialized.

Upcoming Weekend: Stay Tuned
UPDATE:
Unfortunately, I wasn't able to do any flying as we were REALLY busy getting the house ready for the upcoming wedding. We'll see if I can't get some flying done on the Sunday/Monday after the wedding. (October 4th!)

Seeing is Believing: First FPV Flight

Development Stalled: Microcontrollers are Hard to Debug with PRINT Statements

GPS Success: Navigation Data Acquired
Next steps are to decode the stings and assign the outputs to readable variables. Anyone have a GPS output simulator?

Progress Continues: Microcontroller and GPS Purchased
- Has a serial input
- Multiple Analog input/output controls
- Very cheap (~$30)
- Familiar programming language
- Large user help base
- Cheap (~$55) seeing a pattern here?
- 5 Hz refresh rate (say wah!?, most are 1Hz, or even 1/2Hz)
- Serial NMEA output

EasyStar Completed
Construction Continues: Organizing Internal Components
One more motor mount closeup
Two halves of the the aircraft just before I glued them together
Here you can see some of the internal components (from front to back):- The 6-Channel JR Receiver
- 500mW Video Transmitter
- Camera Voltage Regulator
The following items round out the rest of the components:
- Camera Battery
- Flight and Video Transmitter Battery
- Brushless Electronic Speed Controller
- AXI 2212/20 Brushless Motor

A New Beginning: EasyStar Construction Begins
Thursday, January 10, 2008
Platform Selected: Multiplex EasyStar
1. Multiplex EasyStar
Very affordable ($59)
Probably fits all my current equipment (propeller will most likely be too wide)
Easily upgradable
Spare parts availableMost expensive of the bunch ($99)
Landing gear
Greatest wing area (for slower flights)
Not as easily modified
Sort-of Landing Gear
Relatively expensive ($98)
(Honestly, I didn't research this one much)

The Search Begins: New UAV Platforms Being Evaluated
- Portability of current power system (Motor, Speed Controller, Battery)
- Availability of spare parts and/or repairability
- Slow speed
- High lift
- Pusher prop (so propeller doesn't get in the way of the video feed)
Many people have been using the Mutliplex EasyStar, but I feel this may be due in part to the large success of vrflyer using this platform (essentially many people probably just copy his setup).
I am looking at possibly buying the Wingo Porter (see picture above). It has two motors, HUGE wing area, and is very durable and repairable. In addition, the Porter is also designed to carry a payload. Unfortunately, it appears as though it may no longer be available.

Disaster: Nipper Damaged

First Video
Success! The system worked like a charm, except for some sporatic interference mainly due to me flying behind a hill which was blocking the video RX. Erik served as Ground-station Master General and manned all the electronics on the ground while I flew. We flew for about 15 minutes and captured a lot of great video. Since I didn't have a free channel to control the pan mount of the camera, I decided to couple the rudder to the camera movement. Unfortunately, the ratio of camera movement to rudder movement was far too small. This resulted in almost no pan ability because the massive rudder control threw the plane into death spins. Landing was 'interesting' as I tried to slow the plane down to a safe enough speed for Erik to catch it; unfortunately, in addition to my shoddy piloting skills, the heavy plane just wouldn't fly slow enough for a mid-air retrieval.
