Replacement Motors & Props
     There are 3 different weight motors in the kit. They vary in a range somewhat narrower than our selection (#376 is smaller than the narrowest, our #378 is larger than the largest supplied with the kit). These weights are custom cut and not available commercially. Our closest match is the .0938 (M377). It is at the high end of the motors supplied with the kit. You may compensate for increased mass per unit cross section by increasing prop pitch, which will slow the prop speed. If this increases thrust more than is desired, you may compensate if the plane climbs too quickly by backing off some winds (experiment to see how many). The real issue is the total mass of rubber. Width is not entirely reliable, since thickness varies a little. There is probably no single ideal value for motor weight and prop pitch taken together. 
     Ikara props - same as those included in kit - are available on our construction supplies page.
