When building or upgrading an RC crawler, basher, or heavy-duty scaler, choosing the right motor is key to achieving the performance you need. Two common choices among hobbyists are the 795 and 895 motors. While they share some similarities as large-format brushed motors, their differences can significantly affect your rig’s torque, speed, and overall behavior.
This article breaks down the differences between 795 and 895 motors to help you decide which is better suited for your setup.
Size and Design
The 795 and 895 motors are both part of the “can” motor family, larger than standard 540 or 550 motors. These motors are often used in 1/8 and 1/10 scale RC vehicles that need extra torque, such as crawlers, heavy scalers, boats, or tracked vehicles.
- 795 Motor: Slightly smaller in length and diameter compared to the 895. Still much larger than a 540/550 motor, offering increased torque and better low-speed control.
- 895 Motor: Larger and heavier. Provides even more torque than the 795 and is often used in extremely demanding applications like dual-motor MOA crawlers, 6×6 rigs, or custom tanks.
Winner: 895 for torque; 795 for a more compact form factor.
Torque and Speed
- 795 Motor: Delivers a strong balance of torque and RPM, ideal for crawlers or scale trucks where you want good low-end control without sacrificing too much speed.
- 895 Motor: Prioritizes torque over speed. It has a larger armature and magnets, allowing it to pull heavier loads or tackle steeper inclines without overheating or stalling.
If you’re building a heavy rig or need slow, deliberate crawling power, the 895 is the stronger choice. However, the 795 is more than capable for most 1/10 crawlers and will often be more responsive due to its slightly higher RPM potential.
Winner: 895 for heavy-duty torque; 795 for better speed-torque balance.
Weight and Power Consumption
- 795 Motor: Lighter, which can be a benefit for weight-sensitive builds. It also draws less current under load, making it easier on your ESC and battery.
- 895 Motor: Heavier and more power-hungry. You’ll need a high-amp ESC and battery setup to support it efficiently, especially if running it in high-drag or steep terrain.
Winner: 795 for lighter, more efficient setups.
Use Cases
- 795 Motor:
- Ideal for 1/10 scale crawlers, scalers, and trail trucks.
- Great for those who want more torque than a 540/550 without excessive weight or power draw.
- 895 Motor:
- Best for custom rigs, heavy crawlers, 6×6 trucks, tracked vehicles, or competition MOA setups.
- Also a solid choice for RC boats or vehicles that require continuous, high-load torque.
Winner: Depends on application. Choose based on your rig’s weight and terrain needs.
Conclusion
If you’re upgrading from a 540/550 motor and want more torque without overcomplicating your build, the 795 motor is a great middle-ground option. For those with heavier rigs or extreme crawling needs, the 895 motor offers unmatched torque and load-handling capabilities, albeit with more power demand and weight.
Always match your motor with an appropriate ESC and consider gearing adjustments to get the best performance out of either option.
