  • Update

We added picture of ballast for wing and new ballast for wing joiner. New improved RDS was develop. Servo frame is now with balls bearing for better accuracy and simpliest mounting. Ballast for joiner was also added to jitom calculator.

We have calculated the performance of the Evolution V-Tail model using the XFoil program. We hope that this knowledge will allow better settings for your model and will contribute to improving the properties for a new model. We plan to compare the calculated results with the actual parameters of the model using a barometric altimeter and GPS logger as soon as possible. So far, however, the results appear to be remarkably accurate (for example minimum sink rate).


Results were calculated for a model weight from 2200 grams to 3400 grams with 400 grams resolution. It appears that for distance and speed task, more weight means a better outcome. The graphs also show the maximum glide ratio and maximum flight efficiency. For distance task it is good to move between the maximum of these variables. For Evolution model the trim speed is almost the same as the speed for maximum glide ratio. All calculations are for a model with control surfaces (v-tail, elevator, ailerons, flaps) in neutral position. Later we compute also optimum flaps angle for achieve maximum lift for start on winch and appropiate elevator correction.
