I just switched to three bladed props and found that the sanding balancing method I use on two blade props was not efficient. I've switched to using tape to balance the three blade props. My question is: Where is the optimal spot to add tape? I've been adding mine to the tips thinking that because of the leverage it would take less weight. But are there other factors here that I'm not taking into account? Where (top or bottom of blade) and on what part of the blade are folks adding tape? Also what type of tape is being used?
