# Volantex Ranger-Ex QuadPlane VTOL (Pixhawk)
The QuadRanger VTOL is a standard tailplane aircraft based on the Volantex Ranger-Ex that has been retrofitted with a QuadCopter system. The Ranger-Ex is an easy to fly FPV platform that is widely available. It is also available from HobbyKing where it is rebranded as the Quanum Observer. The plasic fuselage and 2 meter EPO wing makes it a rugged airframe with a lot of payload capacity.
Key information:
- Frame: Volantex Ranger-Ex or Quanum Observer
- Flight controller: Pixhawk
The VTOL conversion makes the plane a bit heavier (around 3.5kg including LiPo). With this conversion the plane will cruise at approximately 65% throttle. The suggested quad setup provides a thrust of 7.5kg and the airframe can fly with a total weight of around 4.5kg. This leaves enough payload capacity for payloads like FPV gear and cameras.
The conversion is designed to minimize impact on the aerodynamics and provide additional strength minimize wing flexing.

# Wing conversion
A full build log is provided in the following video.
Note
Please note that the conversion in this build log is performed on a wing that shows damage from a previous conversion.
将两根 800 毫米方形碳管分别切割成 570 毫米和 230 毫米长。
使用旋转工具在泡沫塑料机翼上开槽，深度为 1.5 厘米，并使用某种形式的导向装置保持固定深度。槽的长度、深度和宽度应与一根 230 毫米的方形碳管相当。位置如下所示。
用 CA 胶水将 300x150x1.5 毫米的碳板粘到 230 毫米的碳管上，然后开一个口子，将电线穿过。插入电调的电源线和信号线。使用 UHU POR 胶水将碳板和碳管粘到泡沫塑料机翼上，如下所示。
用 CA 胶水将 570 毫米的方形碳管粘到碳板上。碳管的位置应距离机翼连接处 285 毫米。碳管应位于机翼垂直区域的中心。其两侧的延伸长度应正好为 165 毫米。
将马达支架安装到马达上。用另一块马达固定板和 4 个 M3x25mm 螺丝将马达夹在方形碳管的末端，如下图所示。用扎带将电调固定在碳管上。使用 Afro 电调时，确保至少连接信号线和接地线。
# 布线
Pixhawk 的输出应该这样接线（方向就像坐在飞机里看到的那样）。
| 港口 | 连接 |
|---|---|
| MAIN 1 | 右前电机，CCW |
| MAIN 2 | 左后电机，CCW |
| MAIN 3 | 左前电机，CW |
| MAIN 4 | 右后电机，CW |
| 辅助 1 | 左副翼 |
| 辅助 2 | 右副翼 |
| 辅助 3 | 电梯 |
| 辅助 4 | 舵 |
| 辅助 5 | 节流阀 |
备注
使用 QGroundControl 的 PWM_OUTPUT 组（齿轮选项卡，左侧菜单最后一项）中的 PWM_REV 参数，可以反转伺服方向。
