Ok, just about the detail I am willing to do
has been added except for few more items, but for now the matching
lower wire cutter has been added along with relieving
the pockets for the belly pan latches which will be bolted
on after painting. I still have to make those
items...also installation for the final tail rotor drive will be done soon.
......
Shown here is how the reliefs were made
using strip abs and CA glue (a hot knife made the cutouts). Now onto
the final tail rotor mounting. I used 7mm thick
ply with lamination of 4oz. carbon fiber cloth on both sides. I used
only thin CA glue to make this lamination and
the bulkhead is now probably the strongest area of the entire heli!
.....
I am setting up this tail rotor
on the left side, but it could easily be flipped over for right hand use.
I want this model
to fly on the same mechanics I already have set
up for my S-76 model (left hand). So I am saving thousands of dollars
doing things this way plus the model will really
fly great not to mention all the blade choices there are left hand rotation
systems. Only the rear tail rotor cover need
be replaced to switch over to right hand later. I added this triangle support
to further enhance the tail section and bulkhead
support.
......
The tailrotor cover in place. The
floating look is exactly scale.
......
The vario gearbox was converted
with stub shaft instead of the claw coupling. I will be using the SSM flex
drive
that we offer to outfit this model. It is quite
strong, vibration free and lighter than using a boom mounted drive shaft
system. The flex drive installed , the stout
cable housing (sprial stainless steel covered in black rubber) is sleeved
with a thin wall 10 mm alu tube. Supported in
rear at the tail rotor, mid-boom, boom to body joint, and then finally
right in front of the mechanics. The sleeve is
bent in a gentle/flatened "S" shape from front to rear and couplings
run perfectly true using 8 3mm set screws
on each to secure them. 44 tiny screws secure all the drive shaft covers
in place in thier scale locations.
