I have been a glow flyer for over 30 years and due to noise abatement in my community I must switch to electric. I am also a scratch builder and am looking for a place where I can learn the basics of electric propulsion. Can anyone direct me to a place where I can get the following questions answered?
1. How do you determine what motor is required for a certain size plane? Is is based upon weight of the complete plane? What motor characteristics are considered when making the selection?
2. Once you determine the motor, how is the battery size determined? what determines the amount of MAH and cells?
3. Is it correct to assume that a 30A ESC is sufficient for a Lipo with a 30A power rating?
4. What determines the correct propeller size? Is there a table somewhere that this information can be gleaned?

As you can tell, I know nothing about electrics and need LOTS of help. I flew a Zagi about 10 or 12 years ago and that is the sum total of my experience with electic RC. If you want, you can respond direct to [email protected].

Many thanks in advance.
