==<br> Introduction ==

I decided to try something much smaller in the Wing world. The Z84 is a smaller version of the C1 and FX-61 and I am hoping it flys well as I want to take it backpacking! For flight management/control I'll be starting with an Omnibus F3Pro flight controller to keep it light and simple.<br>

Here then is a collection of my build notes and eventually a flight review of this plane.<br><br>

== Components/Flight Gear ==

Below is the approximate layout of installed components:<br>

==== Power Set-up ====

For power on this build I will start with a Multistar Elite 2204-2300kv motor and a HobbyKing Blue Series 20A with a single Low ESR capacitor added.<br>

:* Motor - Multistar Elite 2204-2300kv
:* ESC - Blue Series 20A
:* Prop - HQ6x4.5
<!--:: For more informaion on setting up a pusher folding prop - <u>[[How_To_-_Set-Up_a_Pusher_Style_Folding_Prop | How To - Set-Up a Pusher Style Folding Prop]]</u>-->
:* Battery - Li-ion 3S/3500<br><br>

<br><br>->>

===== Motor Mount =====

I have designed a 3D printed motor mount which places the motor 10mm rearward of the stock mount. This is to accommodate a standard 22xx motor and standard prop. To use a folding prop I will have to put the motor on an additional 10mm stand-offs.<br>

<br><br>

''' ESC Mount '''<br>

I decided to design and print a simple mount which glues into the motor mount and bottom of the fuselage. The ESC is held down with a single wire tie and there is a foam pad between the ESC and mount deck.

<br><br>

==== Flight Control ====

For initial flight control I chose the Omnibus F3Pro from Banggood. It is an inexpensive and in my experience completely reliable FC. This is the same board I have in the larger C1 Chaser<br><br>

:: w/iNav 1.8.1
<br>

''' FC Mount '''<br>

To mount the FC I Glued in some 10mm stand-offs in the bottom of the fuse.<br>

<br><br>

'''RC Control'''<br>

For radio gear I am using my standard DragonLink V2 system. I have mounted the RX with integrated DL dipole inside the left verticle stabilizer.<br>

<br><br>

'''GPS Mount'''<br>

For the GPS I used the same mount as on my C1. This is sized for a Ublox Mini M7 GPS.<br>

=== Fuselage ===

I made some initial changes based on experience with the C1 and FX's.
<br>

The first change was to swap the very flexible fiberglass spar for a slightly larger Carbon Fiber tube spar. THe CF spar is slightly lighter but considerably stiffer. I only had to do a small amount of hot-wire work to fit it in nicely. Of course this means I will have to come up with my own hatch latch (stay tuned)<br>

|-
| align="center" | [[File:Z8419.JPG|700px]]
|-
| align="center" | Spar change
|}
<br><br>

The next "Aero" change I made was to cut down the center fin on top of the hatch and grind away the rear flare around the motor mount top and bottom (not shown). The fin on top just collects damage. The flare around the motor mount makes the prop less efficient and much, much noisier!<br>

== Kit/Build Review ==

I opted for the bare bones kit because I live and fly at 2500ft or more altitude and it has been my experience that most PNP setups are underpowered and supplied with servos that could be improved, etc. With that said, all in all this is a really nice kit. The linkage components in mine are well made and sized perfectly.<br><br>

Here are some of my personal points for improvement:<br>
