[Chat] Why Did you Steal The Batteries?

2 batteries of our T-rex was stolen during I flew the T-rex. I was concentrated on practicing the side hovering and didn't know who took these 2 batteries away.

Why? I don't know who else also fly electric RC helicopter around here. Maybe someone regarded my as garbage... because I put them on the ground?

Maybe someone didn't like to see me fly helicopters on the grass. Okay!! I will fly!! I will fly our helicopters everyday!!

[Heli] ALIGN 2006 funfly in Kohiong

Date: 2006/12/09
Time: 10:00-15:00
Location: in front of the Kaohsiung Museum of Fine Arts

ALIGN held the activity for popularizing the RC helicopters and of course also their products. They invited 3 famous RC helicopter pilots, Alan Szabo Jr., Jason Krouse and Nigel Brown to make amazing 3D flying shows.

It is not easy for me to have the opportunity to meet these famous men face to face. Therefore, I invited some of my friends to attend the activity. They were very happy to see these RC pilots and thier stunting 3D flight.

However, I missed the most improtant show in that afternoon. I thirsted so much and then went to buy some iced drink. Unfortunately, I got into a traffic jam and couldn't get back to the field to enjoy the show!! Also, I missed the chance to take photos with all the people in the activity... Orz

After I was back to the field, all the shows was over!! What I could do was just to ask Alan, Jason and Nigel to autograph on the back of my visiting card. Finally, I took the photo with Alan and my friends. :-)

[Heli] T-rex flight at HIGH altitude (2280 m)

How high can the small electric helicopter fly at? Someone asked me about this when they saw me fly T-rex in front of our institute's building.

All I can say is only "Oh, very high, far beyond you can see it."

On December 1st, 2006, our lab went to the Southern Cross-island Highway for calibrating one of our altimeter. I took the T-rex with us because I just curious about the performance of T-rex at high altitude.

After the flight test, I can tell you "It still perform good for hovering at 2280 meters high." At that height, the air density is 80% of that at sea level.

[Heli] Unmanned Helicopter Project: H-LING

H-LING is one project of our lab. It is supported by National Science Council.

Our goal is to make the helicopter hover automatically. There were many flight tests to get data for system identification or some kind of analysis.

I am very lucky to involve in this project. For testing the vehicle, I have many opportunities to flight the helicopters. They are Raptor-90, 50, and even Hirobo Freya.

Here are some photos about our flight test on Novemver 24th, 2006.

Raptor-90 was ready to take off. I just checked it before our test pilot's coming.

I was talking to our test pilot (Tan Po-hu, the left one) to let he know what kind of flight data we want to get.
