Hi all modelers forum . We wish you all the best for the New Year 2014 , the same successful design, and starts. : wv
Last year we did not have much time to make the models but few structures arose. One of them is presented below .
The first attempts AirBoat 7 in winter unfortunately been przeprowadone on the water. We were waiting for snow, never received , and probably will not live to see . Therefore, attempts to take on water. Now, specifically , the model weighs 2400g (with all accessories) , is powered by a 900W motor Emax , we tested three types of śmiegieł EMP 11x7 , 10x8 Graupner , and the third propeller of unknown origin , but has written propeller 240x170 . When all attempts of these propellers hull did not behave too stable , and even also the speed was much smaller than expected. We'll see how he will keep the snow if this year at all fall. In this case, the shape of the hull can not be drifftować . At least for the time being we have failed to achieve. Attempts will continue to carry out , but we see the black hull , does not meet our expectations. The only advantage of this hull is that the sides of the upper portion is at an angle which makes the hull is less cranky (tested in several models ) . After these tests , we concluded that the hulls simple such as AirBoat 5, exhaust and 7.5 ccm 26ccm ( first version ) are preferred for fast swimming and drifftowania . Make these include only the upper side at an angle and models will be very well sailed . One more thing, for beginners electrics are sufficient , but you need to stock up on 2 packages to swim longer and for those more demanding in good conscience recommend the fumes .
Below the video of our trials.
