Armattan has been asked many time to design something smaller for 65mm props. They have been reluctant for two reasons :
The first reason is that there were not many options for small motors and even props for quite some time. By now the popularity of such weight class has brought about many more options in terms of motors, but also good options for 16 x 16 stacks that can run such small models well.
The second reason is that they were not fan of minimalistic frames with a POD style 3D printed or plastic canopies and not fan either of bottom mounted lipo for frames made for freestyle and fun flying. Seems most freestyle frames today do not bottom mount the lipo. The word is that a top mounted lipo offers better flying characteristics.
They eventually pulled out their pencils and decided to draw something up. Their goal was to make something light, strong, and it had to have a top mounted lipo. For example, looking at some 5 inch models that have a top mounted lipo, it seemed obvious that the rear end of the model needed not to have the same stack height and needed not to be so wide… These two things alone allowed for shedding enough weight that we stood a chance to make weight.
