So it's the first time I'm trying to build an RC plane and I'm really struggling. It would be really amazing if somebody can nicely advise me (I understand I'm stupid). So, the parameters I have are:
I need to calculate the propeller-battery-motor system, but I guess I dont know where to start or what equations to use. Based on this parameters, how can I calculate what type of motor do I need (rpm, voltage & current) in order to hook it up to a propeller & lipo batteries. Am I missing any parameter?
- Max wingspan of 5ft (estimated wing area = 4.2 ft^2 with a chord length of about 10 inches)
- Being able to fly at least 40 mph (at this velocity, it creates a thrust of 10lbs)
- So I'm guessing the weight of the plane needs to be less than 10 lbs
- I want to use two motors, one that connects to the controls system (receiver, ESC,etc..)
- and a separate for the propeller
- Using lipo batteries
