    I have a small issue, I am a twin motor plane junky, the issue I have it selecting motors, using the single motor system and spitting the power required to get her in the air is not working too well, either the plane is under powered or I have to fly at 75% throttle or more to keep her in the air.
    Is there a system I can use to help me figure out the correct motors and power system I will need?!

    Thank You for any help ahead!

    Usually a dual engine plane, especially a prop plane, requires two engines because of the weight it has to pull or carry. So these engines are usually quite large. IMO, I would figure out what motor you need for the plane if you were just going ot use one, then get two of those motors. Maybe put a more aggressive prop on it, but just keep an eye on your temps.

    For anybody to help they need to know the details of the aircraft ie. weight, wingspan, wing cord etc so that they can estimate the wing loading, a photo would probably be good as well.
