Honey Bee King 2 Fix and Successful Lift Off


[4-Jun-2009 Thursday]

Continuing from the damage state of my Honey Bee King 2, here were the fixes I made:
1. Replaced of fly bar
2. Replaced the broken piece of bell control arm set
3. Replaced the main rotor blade
4. Glued the broken front skid

As the size permit, I was able to brought it back to my home town in Kelantan which is about 450km from my house (I drove there).

[14-Jun-2009 Sunday]

At my home town, Kadok Kelantan, I did the test flight.

I have it prepared, everything was ready, I utilized a big space where we used to play badminton/sepak takraw/ tennis at my mothers house.

I slowly increased the throttle, taking my own time and have the feeling of how the tail response. The response is not really consistent, however the gyro was able to hold the tail at the same direction at high rotor speed. I increased the throttle further and have the HBK2 light on its skid and then have it tilted to its right, standing on its right skid, balancing it with my stick control. I hold it for a while to ensure that is was really stable.

Then I continued to do the lift off. Yes, it was a successful lift off, however I do not brave enough to fly the helicopter above 6 inch! I don't feel the control was stable enough, it was quite erratic. Landed and did another take off till the battery low warning buzzing out.

Yes it was a successful lift off for my Honey Bee King 2!

[8-Jun-2009 Monday]

On the next morning, I was ready to test out the HBK2 again. This time I was more confident and hoping to get it flying higher and probably holding at hover for longer time as well.

Same location, I made all the setup. Did the lift off, however suddenly I found that HBK2 move very erratically. I was not able to composite for the movements. My attempt to correct it either not enough or I did over correction to the flying, resulted it crashed to the near by small trees. :(

I have only the main gear and main blades damaged.

I guess I was just over confident.

After some checking, I noticed that some pitch/roll movement of swash plate did not return back to the 'normal' position after I released the stick. The return position when I move up compared to move down the stick is different. This must be the reason why I could not hover correctly and crashed.

I will continue to investigate why is such thing happening.
