Brakes - 5 hour (133 Total)

Today I did several different things. First, I bolted the hummertangs to the bottom end of the tail boom. The bolt appears to be too long. It bottoms out on the nut plate and there is about 1-2 mm of play.

I then attached the eye bolts to the ends to the elevator yoke.

I then installed the throttle mechanism. I needed to make several modification to allow the system to move more smoothly. First, I bolted the friction rod onto the inside of the throttle lever. The manual shows the friction rod on the outside of the lever but in this configuration, the rod isn't lined up with the friction block opening. This causes the friction to vary depending on where the throttle lever is at. I also rearranged the washers so there was one washer between all three components, the rod, the lever, nut, and bolt head. These two modifications may cause interference with the closest of the three throttle cables but I only plan to use two.

The second modification I needed to make was to rotate the friction block so the slit pointed down. This lowers the friction rod which gives one of the throttle stops the clearance is need. It was hitting part of the frame.

I also needed to drill out the throttle knob to 7/16. I plan to have a nicer throttle knob made out of wood. I can't make the newer knob too much larger because of the limited clearance between it and the flap lever.

I then installed the brackets for the instrument panel. I used tape to hold the brackets in place to test fit the Instrument Panel and Front Panel.

Finally, I cleaned up the two lexan nose pieces. I tried using tin snips to cut the lexan but this was difficult and didn't make a very clean cut. My Dremel Tool again saved the day! It cut through the lexan easily with a cutting disc.
