==<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>

===== 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>

''' 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.

==== 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>

=== Airframe Changes ===
+
−
 
+
−
I made some initial changes based on experience with the C1 and FX's and listening to some of the more expert posters on RC Groups.
+
−
<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><br>

−
|-
+
−
| 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 and blocks air to the prop. The flare around the motor mount makes the prop much 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>
