Introduction:
Not all FPV drones can use standard motors. Different airframes, different missions, different payloads—sometimes you need a custom motor.
Tenswall offers customization services for FPV drone motors. From KV value, shaft diameter, wire length to color—we can adjust to your requirements. This article explains the customization process and what you need to pay attention to.
1. When Do You Need Custom Motors?
You may need custom motors in the following cases:
-
Specific KV value – Standard KV doesn't match your requirement
-
Specific shaft diameter or length – Your propeller mounting requires a custom shaft
-
Specific wire length or connector – Your ESC layout requires specific lead length
-
Specific color or logo – Your drone brand needs consistent color matching
-
Large OEM orders – You need your own branding on the motors
2. Tenswall Motor Customization Process
Tenswall's customization process follows these steps:
Step 1: Requirement Communication
Client provides requirements (KV value, shaft diameter, wire length, quantity, target airframe, application, etc.)
Step 2: Solution Confirmation
We provide a customization plan and quotation based on requirements
Step 3: Sample Production
Produce samples after plan confirmation, test performance
Step 4: Sample Testing
Client tests samples, provides feedback (if any)
Step 5: Mass Production
Enter mass production after sample approval
Step 6: Quality Inspection & Shipping
Full inspection before shipping
3. Common Misunderstanding in KV Selection
"Higher KV means faster motor" – this is a common misconception among beginners.
In reality, KV selection must be considered together with motor size, propeller size, voltage platform, and flight mission.
Taking Tenswall 4220 motor as an example:
| KV Value | Suitable Application | Notes |
|---|---|---|
| 350KV | Heavy-lift, long endurance, large props | High torque, high efficiency, suitable for 15-17" props |
| 420KV | All-round performance | Balanced torque and speed, suitable for 13-15" props |
| 450KV | Speed priority | Higher speed, suitable for 12-13" props |
| 800KV+ | ❌ Not recommended | Excessive speed causes high current, overheating, and efficiency drop |
Higher KV is not always better. The key is finding the balance between motor size, propeller size, and flight mission.
4. Important Notes for Custom Orders
Custom motors are different from off-the-shelf products. Here are a few key points:
1. Minimum Order Quantity (MOQ)
Custom products typically have MOQ requirements. Communicate this clearly with the client.
2. Lead Time
Sample production + mass production require sufficient time, usually 2-4 weeks.
3. Cost
Customization may require mold development or production line adjustments. Any additional setup fees should be communicated upfront.
4. Intellectual Property
For OEM orders, brand ownership and usage rights should be agreed upon in advance.
5. Testing Standards
Clients are advised to fully test samples. Once mass production starts, changes cannot be made arbitrarily.
