First Helicopter Aerial Video Attempt

Off I went to the field early this morning to shoot my first ever in-flight video on a RC helicopter. Wind condition is perfect, no wind at all. Temperature is a bit cold (-10) but the sun is up to warm things up a bit.

The C.G seems to be pretty well balanced even with the new payload (the Speed DX8 video camera). The 1100mah 25C light weight li-po did fin. The only disadvantage is that my flight is limited to about 2 minutes only (3.8v for each battery cell after the flight).
The camera is tilted a bit downwards too much. During a heli fight, the heli is often a few degrees nose down providing the horizontal trust component for forward flight. I should have slightly adjusted the video camera to be facing upwards so that I wont be videoing the ground for most of the time. More in-flight videos coming soon!

T-rex 450 Conversion - Aerial Video Platform

I've always enjoy taking in-flight videos with onboard cameras. I’ve done it many times with planes but never with a heli. My heli flying skills have improved a lot lately and I’m planning to take my first heli in-flight video soon with my T-rex 450 Helicopter. The video camera I will be using is the Speed DX8, which is quite a light video camera with 640x480 resolutions. Instead of using the origonal 2200 mah li-po I’m also planning to use a 1100mah battery instead to reduce the flying weight. Here are the modifications I made on my T-rex 450.

1. remove battery tray
2. relocate the Speed Controller and BEC to the side of the air frame
3. secure the Speed DX8 video camera with rubber bands
4. 1100 mah li-po secured underneath the air frame

Birthday Flying

Well, its Feb 16th, I finally turned 18... and I want to do something special to celebrate this time...

The sky is blue, wind is clam, weather is warm... my li-po batteries are fully charged...
off I went flying my Trex 450. Heli flying is a very new kind of flying to me, all I could do is hovering and some simple "lazy 8s". No stunts at all but who cares, fun enoguh for me!
