Title: Re: need help with my trainer Post by: swapnilnimbalkar on July 14, 2017, 12:01:42 PM Calculate the estimated weight of the plane.
Then calculate wing loading you will get a general idea how the plane will fly. Generally lower the wing loading number, plane will be of floater type. If this is your first plane you should build one with wing loading below 10. And try to ask your questions in the same thread you made previously. Dont make new thread every time you have a question. (This is just a suggestion) Title: Re: need help with my trainer Post by: Ssk3112 on July 14, 2017, 12:02:56 PM Sir my plane weight is around 450 grams

Im using 14000kv motor 30amp esc 2200mah lipo 1045 prophs ...???? As per the details given Wing area = wing span X chord = 35in X 6.69in (17cm) = 234.15 sqin Wing area in sqft = 234.15/144 = 1.62 weight in oz = 15.87 oz (450 grams) Wing loading = weight in oz / Wing area in sqft = 15.87 / 1.62 = 9.79 oz/sqft Your planes wing loading comes out to be 9.79 oz/sqft which is quite high for the beginner. Consider another example: Wing area = wing span X chord = 46in X 10in = 460 sqin Wing area in sqft = 460/144 = 3.19 weight in oz = 15.87 oz (450grams) Wing loading = weight in oz / Wing area in sqft = 15.87 / 3.19 = 4.97 oz/sqft This plane will fly quite decently, will be controllable and slow flyer. I have given dimensions in the previous jpeg image. Consider those dimensions. Also I have sent you a Personal Message (PM). |
