Default e-Neptuno

After many months of prototyping I finally received the production version of the e-Neptuno. It arrived safe and sound this past Friday afternoon. I will be using this as a build thread for the Neptuno. I'm currently building the glow Neptuno as well... so I'm building two planes at the same time. My hope is to have both planes ready in the next 3 weeks or so. Here are some pictures of the e-Neptuno and some weights of all the components. I'm the importer of the Neptuno into the USA - cost of the e-Neptuno is $1500 excluding shipping. It is a composite plane as you will see and it is a large bodied plane. Included with the kit are all the goodies one needs to finish the plane such as control horns, spinner, tail wheel, axles, pull-pull cable for rudder, etc.

Some pictures...

Some weights of the components...

Fuselage - 945g
Rudder - 55g
Wing tube - 40g
Left wing - 400g
Right wing - 410g
Left stab - 115g
Right stab - 145g (includes stab tubes)
Spinner - 95g
Wheels - 20g
Wheelpants - 30g
Landing gear - 105g
Accessories - 135g (nuts/bolts/screws/control horns/clevises/motor mount, etc.)


I'm estimating that with a Hacker 14XL and all servos, wiring, batteries, etc. the plane should come out around 4860g.

Picture of the accessories, stabs, wings, fuse front, wing mounting area (including adjusters), stab mounting area, fuse rear and the removable rudder.

Gorgeous, a well thought out ship it would seem.


Is it on sale yet or is this the first production cab off the rank?

I saw the nitro version up close at the AMA show in California last week. It is a very nice looking plane and the quality looked very good.

Because it weighs more. Holy cow, Dave was right[X(]. lol. jk obviously.
No seriously, the glow price came from Adrian. Not saying he isn't correct, but Derek will be able to tell us the glow price.

I'm assuming because it is wood built up, glass covered and painted. The EP version is composite.

Ok, so here goes with the build... I'm starting off with the back of the plane and I'll work forward. Why? Just because... Actually, I sent my 14XL in for service and I'm waiting for it so it doesn't make any sense to hold off on the build until I get it back so I'm starting at the back and my hope is that by the time the motor comes back I'll be ready for it.

The pictures pretty much tell the story... stab servo installation and control horn setup. I never made one modification or enhancement to the installation. This whole process took me about 20 minutes at the most per stab. Photos are:

1. The parts packets that will be used
2. Servos that will be used
3. Servo outlet on the stab
4. The stab root has foam covering which makes a tighter fit when the stabs are mounted to the fuse
5. Removed the covering over the servo box with an Xacto knife
6. Total weight of the servo and assorted bits and pieces - total weight of the left stab was 115g before any equipment was installed
7. Total weight of the control, rod and clevises
8. Servo trial fitted in the stab - as you can see there aren't any screw holes marked yet

I then marked the screw holes with a fine point marker and used a heated pin to "burn" the servo mounting holes in the plywood brackets. In went the servo afterwards with the screws. Next step was to put the control horn in - I used the supplied bolt and associated hardware. I used a little Loctite on the threaded rod to ensure it stayed in place without backing out. The next step was to make up the control rod using the supplied ball link clevises. Everything is the right size and no cutting was needed. The only additional time taken was to ensure the rod was the right length and the stab was "flat" without any up/down trim.

Pictures are as follows:

1. Servo screw locations marked
2. Pin used to "burn" through the plywood to ease the servo screw access
3. Pin is heated
4. Holes made using the pin
5. Servo now mounted
6. Control horn for elevator
7. Partly screwed in
8. Screwed flush with the top of the elevator
9. Mounting the underside of the control horn
10. Adding Loctite to ensure the bolt doesn't move
11. Hardware mounted on control horn
12. Ball bearing part of clevis mounted

Stab work continued...

Photos are:

1. Control rod completed
2. Servo arm installed
3. Control rod installed and showing the weight of the completed left stab half - 150g. We started off at 115g so we added 35g total with the servo and associated hardware.
4. Both stabs finished and joined on the stab tubes
5. Installed hardware

Next step is the installation of the removable rudder and also the control horns, cables and servo. Here are some pictures to get you started... work on the rudder will start tomorrow and continue through the next couple of days. I'll take weights later...

Pictures are:

1. Rudder control horn and associated parts
2. Servo, cables and servo arm to be used
3. Everything in one picture

Derek,

Not sure if it's my eyes or not but the roots of both stabs look a little rough in the photos. [:'(]

Also, why would you make the holes with a hot pin over a drill bit? [&:]

Cheers
Jason.

Hey Jason,

It's your eyes! See one of my earlier posts - the root is lined with foam that's why it looks rough. As for a hot pin versus a drill... personal preference (less messy) and also the one side would be difficult to get a drill in there since it is positioned slightly under the lip of the root.
