I am using a 0s .40 and a evolution .46 and a os .91 any info on the prop sizes. This might be a dumb question but better safe than sorry. I have a wide range of props laying around, just want to know which ones will work on which motor. The smallest size to the largest size for each motor would be helpful. I would assume as long as it didn't hit the ground while mounted any prop would generally work. I currently use a 9/6 on the 40 a 11/7 on the 46 and a 14/6 on the .91
