Real-world DJI T50 versus T40 Comparison. CAN IT SPRAY HILLS?

Drone Testing: T50 vs. T40

Introduction to the Drone Test

• Mike introduces the video, highlighting the significance of testing the T50 drone and its capabilities in spraying large areas.

• He mentions a previous unboxing video of the T50 by Taylor, setting context for viewers who may not have seen it.

Key Features of the T50

• The T50 has upgraded features including beefier arms, larger ESCs (Electronic Speed Controllers), and improved latching mechanisms for safety.

• Notable design changes include better cable management that prevents bending during operation and a larger radar system compared to the T40.

• The software improvements are emphasized as crucial for performance in hilly terrains typical in Ohio and Indiana.

Flight Route Setup

• Mike explains their flight route setup, starting from flat terrain before climbing a hill, comparing both drones' performances.

• He introduces their specialized drone spray trailer designed for efficiency with lightweight composite materials.

Initial Flight with T40

• The team prepares to fly the T40 with 99% battery and 7 gallons of fluid loaded, aiming to observe its climbing ability.

• As Mike initiates the mission, he notes how well the drone is performing initially but encounters issues as it approaches a hill.

Performance Observations

• The T40 struggles near the hill; Mike has to manually intervene to help it continue its route after stopping close to an obstacle.

• They activate auto obstacle bypass mode which limits speed but allows continued operation despite challenges.

Transitioning to T50 Testing

• After landing, they prepare to test the new T50 model under similar conditions as used for the T40.

• Mike highlights differences in software between models while expressing hope that DJI has improved functionality significantly.

First Impressions of Flying the T50

• Upon takeoff, Mike monitors speed closely; he expresses excitement when reaching 32 ft per second but hopes for better climbing performance than observed with the T40.

• Despite initial struggles with climbing, there are signs of improvement over previous models as he resets and attempts again.

Conclusion on Performance Expectations

• Throughout testing, Mike remains optimistic about potential improvements in performance due to software updates and hardware enhancements in comparison with earlier models.

Drone Performance Testing: Climbing Capabilities

Initial Attempts and Expectations

• The drone was tested for its climbing ability starting at 10 ft, but it did not perform as expected, leading to disappointment.

• The tester expressed hope that the drone could ascend a hill without stopping, planning to increase the height to 12 ft for another attempt.

Improved Performance at Higher Altitude

• At 12 ft, the drone showed improved performance compared to the initial test; it managed to climb better than at 10 ft.

• A software update allowed for a "Hill mode" on the T40 model, which was selected for further testing with increased target heights.

Challenges in Hill Mode

• Despite using Hill mode at 14 ft, the T40 struggled significantly and failed to climb effectively.

• Transitioning to flat land testing revealed that while climbing was smoother, there were still issues with jerky movements.

Successful Climb and Features of T50

• The T50 demonstrated strong climbing capabilities in Mountain mode, achieving a successful ascent while maintaining speed.

• The tester expressed excitement about the T50's performance and its potential impact on agricultural efficiency by covering more acres quickly.

Final Thoughts on Drone Capabilities

• Cleaning features of the T50 were highlighted as beneficial compared to previous models like the T40.

• Overall satisfaction with the T50's ability to climb steep hills suggests significant improvements over earlier models; this could lead to increased productivity in agricultural applications.
