    Motor Plane Rc
AI Thread Summary
To select a motor for an RC plane, it's essential to determine the required thrust, which can be calculated using general guidelines for watts per pound or kilogram, with higher ratios for aerobatic models. Additionally, the choice of propeller size and pitch is crucial for optimal performance. Resources are available that provide detailed calculations and recommendations for motor selection and prop specifications. For example, a 12-blade fan rotor with a 3200kV outrunner motor and a 64mm duct size is suggested for specific sound and performance characteristics. Understanding these factors will help ensure the successful design of a cargo RC plane.

Good day,

I am starting to design a new cargo RC plane and I end with this trouble.

I want to select a motor but I do not know the required trust.

Is there any equation or steps that I can apply to decide the motor??

Thanks!

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Find 3D Printer & Software Resources for Prototype Creation'

I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
