SPIDER Automation | 22mm X-Type Aluminium Cross Mount Holder | 22xx Brushless Outrunner Motor Firewall Mounting Bracket
Description
The 22mm X-Type Cross Mount Holder is a motor mounting bracket designed for compatible 22xx series brushless outrunner motors. Its cross-shaped structure provides a mechanical interface between the rear of the motor and an aircraft firewall or other suitable mounting surface. The bracket is intended for motors with matching rear mounting-hole arrangements.
Manufactured from aluminium alloy, the holder provides a lightweight mounting solution for model aircraft propulsion assemblies. Its mounting pattern uses two centre-to-centre hole spacings of 16mm and 19mm, allowing installation on compatible motors with either matching spacing arrangement. Eight M3 mounting bolts are included with the two-holder package.
Technical Features & Construction
- X-Type Cross Configuration: The cross-shaped bracket provides a mounting structure between the motor rear face and the aircraft firewall.
- 22mm Motor Format: Designed around compatible 22mm brushless outrunner motor mounting interfaces.
- Aluminium Alloy Material: Metal construction suitable for lightweight motor mounting applications.
- Dual Mounting Spacing: The bracket features 16mm centre-to-centre spacing in one direction and 19mm in the other.
- M3 Fastener Compatibility: Supplied with M3 machine screws for attachment to compatible motor mounting holes.
- Low Weight: Each holder is listed at 1.5g without screws.
- Compact Mounting Profile: Cross-mount format supports installation where a dedicated motor mounting interface is required.
- Finish: The description mentions black electro-coating, while the specification table identifies silver. Confirm the supplied finish before ordering.
Motor Compatibility & Mounting Interface
The holder is intended for 22mm brushless outrunner motors with compatible rear mounting-hole spacing. The source identifies Scorpion 22mm motors, GWS 22mm outrunners, Hacker A20 series outrunners, Waypoint 22mm outrunners and AXI 22mm outrunners as compatible motor families. Compatibility should be confirmed against the actual motor’s mounting-hole pattern and screw requirements.
- Scorpion 22mm Outrunners: Identified as a compatible motor family where the mounting pattern matches.
- GWS 22mm Outrunners: Suitable for compatible models with matching rear mounting holes.
- Hacker A20 Series: Identified in the source as a compatible outrunner series.
- Waypoint 22mm Outrunners: Compatible where the motor mounting interface matches the holder.
- AXI 22mm Outrunners: Identified as another compatible motor family.
- Other 22mm Motors: Can be considered where the motor has the required 16mm or 19mm centre-to-centre mounting spacing and compatible screw threads.
Mounting Design & Installation
The cross holder is designed to attach to the rear mounting face of a compatible motor using the supplied M3 bolts. The opposite mounting interface is used to secure the motor assembly to a suitable aircraft firewall or mounting plate. Correct alignment of the motor holes, bracket and firewall is important for a secure installation.
- Motor-Side Attachment: Align the holder with the motor’s rear mounting holes.
- Hole Alignment: Check the 16mm and 19mm centre-to-centre dimensions against the motor before installation.
- Fastener Selection: Use the supplied M3 bolts only where the motor’s thread size and required screw length are compatible.
- Firewall Interface: Check that the aircraft firewall or mounting plate supports the holder’s mounting arrangement.
- Motor Alignment: Ensure the motor shaft is correctly aligned with the intended propulsion axis.
- Fastener Clearance: Confirm that screws do not extend into internal motor components or interfere with the rotating assembly.

Installation & Operating Recommendations
- Verify Motor Diameter: Confirm that the motor belongs to the compatible 22mm format before selecting the holder.
- Measure Mounting Pattern: Check the motor’s rear mounting-hole spacing against the 16mm and 19mm centre-to-centre dimensions.
- Check Thread Compatibility: Confirm that the motor mounting holes accept the supplied M3 fasteners.
- Confirm Screw Length: Ensure the screws provide adequate engagement without contacting internal motor components.
- Inspect Firewall Strength: Use a suitable mounting surface capable of supporting the motor and its operating loads.
- Secure All Fasteners: Tighten mounting hardware appropriately and inspect for loosening during maintenance.
- Check Shaft Alignment: Ensure the motor shaft and propulsion axis are correctly aligned after installation.
- Inspect Before Operation: Check the holder, mounting screws and firewall for damage or movement before operating the motor.
