Thanks for the info on resonance. Going along that line, how much R&D has LP done on those prop adapters to specifically address the resonance issue? I don't see any write up on this on the Rise Above website that specifically sells the LP Prop Adapter+14" T-Motor props, albeit at a rather pricey premium.Resonance isn't something you can see easily with the naked eye but it can cause vibrations at certain speeds that can adversely affect the props, airframe and cause artifacting in aerial video. Properly engineered hubs can limit resonance and its transfer to the airframe.
