decided to do a test hover soon, just as a checkout, when disaster
strikes. Apparently, I have some sort of bone cyst in my wrist,
and it has been getting progressively worse. I will probably be
having surgery in early September, and then I will be in a cast for
weeks, so this will be my last entry for about a month. I can barely
operate my computer now, building is out of the question until I heal.
Anyway, before it got bad,
I balanced the heli using my balancing rig I built into the
ceiling. A laser level aimed at the head tells me the offset.
Looking for a temporary
weight solution, I turned to the battery bin.
It turns out that the
perfect weight to balance this heli was a pair of 2-cell LiPo's.
Not too far off the expected weight of the instrument panels, pilots,
seats, and whatnot. So far, so good!
Below, you can see the only
two connection points between the mechanics and fuselage: A
dogbone for the tail drive, and a 25 pin connector for signals!
Well, the helicopter is
ready to hover, too bad I am not! (yet).
I wanted to see if I could
still do a little work, using small parts that would go easy on my
wrist. A few months ago I had found some brass ammunition with
metal clips online! These are just beautifully machined! The
tips were painted by simply dipping them into a small tray with a paint
/ reducer mix. This gave me a nice, even, concentric tip for each
shell. I used Red on the cannon shells, and Green on the machine
gun shells. In the meantime, I got out my styrene supplies and
started making ammo trays.
later, I was able to come up with a design that fit the required space,
and appeared to service all three barrels:
Here is what it looks like
positioned on the guns. I had hoped to have the belt extend into
the wing pod, but alas there is absolutely NO ROOM! There is only
1 to 2 mm of clearance between the gun body and the inner bulkhead when
the guns are retracted! (using my Pla-Doh depth gauge).
Airwolf's machine guns also
have a cooling manifold (the lower cannon does not), so I got some brass
tube and started punching out holes on the mill. My 2.5mm end mill
bit has only one tooth, so the cuts are a little rough, but the lathe
will clean this up nicely...
Finally, here are the
completed bits set on one of the guns. Of course, they have to
come right back off, but this is one less thing to worry about when I
get to the final stages. Now, to give my wrist a much needed rest,
I am in agony.
