The Tenswall 3115 900KV brushless motor is designed for 9-10 inch FPV drones. It is a common choice for long-range, freestyle, and cinematic FPV setups.
Recommended Propeller Sizes
| Frame Size | Recommended Propeller | Notes |
|---|---|---|
| 10-inch | 1050 Tri-blade | 10" diameter × 5" pitch, tri-blade design – best thrust and response |
| 10-inch | 1043 Tri-blade | 10" × 4.3" pitch – alternative option |
| 9-inch | 9" propeller | Use matching 9-inch propeller for optimal performance |
Why 1050 Tri-blade for 10-inch FPV Drones?
After extensive real-world testing, the 1050 tri-blade (10×5) is the top recommendation for 10-inch FPV setups. It delivers strong thrust and responsive throttle control while maintaining efficient power consumption. The tri-blade design provides better grip and stability compared to bi-blade propellers, especially during aggressive maneuvers.
1043 can be used as an alternative. The slightly lower pitch (4.3") results in slightly higher RPM, but overall performance remains good.
What is the Difference Between Using 1050 and Other Propellers?
| Propeller | Performance |
|---|---|
| 1050 | Maximum thrust, direct throttle response – the go-to choice for 10-inch builds |
| 1043 | Good alternative with slightly different characteristics – works well as a backup option |
| Smaller (8" or below) | Insufficient thrust; motor performance is wasted, feels underpowered |
| Larger (11" or above) | May be too large for the frame; could hit the battery, arms, or other components if the frame lacks clearance |
What if a Customer Wants to Use Larger Propellers?
If you want to use larger propellers, first check your frame clearance – ensure the propeller tips won't hit the battery, arms, or body. If the frame supports larger props, you may also need to adjust your ESC settings or upgrade your ESC to handle the increased load.
Most Common Question from Customers
Q: "What size propeller should I use with this motor?"
A: "For 10-inch frames, we recommend the 1050 tri-blade propeller. The 1043 tri-blade is also a good alternative. For 9-inch frames, use standard 9-inch propellers."
Summary
The Tenswall 3115 900KV motor performs best with 1050 tri-blade propellers on 10-inch FPV drones, with 1043 as a solid alternative. Always check your frame clearance to ensure the propeller does not hit the battery or other components.
