Ultra Micro RC Plane Vapor

Inspired by Parkzone and Eflite's Vapor, decided to design a smaller Vapor with a wingspan of 25cm as my first 3d printed RC plane project.

It does not take long to print and build this as it is a simple design. This is version 1 and it does fly however any suggestions for improvements are greatly appreciated.

Flying and crashing it on first video take below:

Part 2 adjusted CG and better handling video: 

Below are the details:

Things to print:
1 x Elevator
1 x Elevator horn
1 x Rudder
1 x Rudder horn
1 x Wing Left
1 x Wing middle
1 x Wing right
1 x Frame
1 x Motor mount
1 x Surfaces joint
1 x Esc/Receiver brick holder
1 x Battery Holder
2 x Joint
1 x Front strut
1 x Rear strut
1 x Rear landing gear
1 x Front landing gear
2 x wheel
5 x stopper

Things you need to buy:
* 1 x esc & receiver brick, I am using Eflite's UMX Vapor Lite 3 channel esc/receiver brick
* 1 x 6mm brush motor, I am using Parkzone 6mm J3 cub motor
* 1 x Eflite UMX Vapor Lite gearbox (you wont need the motor mount but you need the copper sleeves/bushings thingy, prop shaft and gear) get plenty of spare prop shafts as well as you will probably break them.
* 1 x Parkzone Vapor's propeller 140x45 (get more as spare)
* 1 x Turnigy nanotech 130 mah 1s lipo battery, Can try those 70mah battery however i am not able to find or ship one in locally.

* Saran/Cling wrap
* 0.5mm stainless steel wire
* CA glue (Super glue)
* 1mm or smaller heatshrink, Just heat and squeeze

Tips on printing and post printing:

You do not need any supports and is optional for the wings to slow down the prints to allow enough cooling. If you do supports becareful when you remove the supports from the wing as to not break it or stab yourself.

The tolerances are made for my Tevo Tarantula and may differ from yours. If the frame is too big you can sand it down and if it is too small you can put some CA on it without the parts attached first so that you can slide the joints and battery holder around to find an ideal position. You will need to glue down parts such as the esc/receiver holder.

I used household food wrap called cling wrap for the wings and surfaces and wrapped using CA glue. You would want to assemble the wing and wrap it together as one piece. Somehow i decided to try using a heatgun with caution to shrink the cling wrap and it tightened it up but i don't recommend doing it as it is high risk of deforming the wing.

As for the surfaces joint make sure the 0.5mm stainless steel wire rotates freely.

My settings but feel free to experiment:

Infill : 100%

Material : PLA, PETG works too

Others : You can test lesser infill or even lower the parts in the slicer to reduce weight. Some makers have tried that with success

Cheers and enjoy making and flying this project as it was a good learning experience

PS: please pardon the workmanship as this is the first rc plane i have build in years
