Summary This is a quick test for a self designed blade design. It should fit onto the hub of a robbe ROXXY 2824-34 brushless motor (fitting untested, but should be close). The model is customizable, but customization is also still untested. It's safest just to modify the blade count and/or the disk diameter. Should be quite feasible to make a multistage radial flow turbine out of this concept design. Right now I realize, that since I chose 33 blades, there may be a little unbalance because it's not devidable by 2 but since there are so many blades this imbalance may be irrelevant. Update: JazzyB just explained that the impeller is in fact in balance because it's three times 11 blades which result in balance - thanks JazzyB!
