I'm not one who skimps on things to get by, but I don't want to put in something that's absurd overkill either. I'm failry new to the hobby so I'm not familiar with the types of sero failures, other than a stripped servo on my US40 after a hard tail first landing(crash). By going with a non digital, or super high torque model, other than stripped gears in an accident, what could fail??? Will they not pull the surface all the way? Will they strip in the air? Thanks for all the replies, it is somewhat entertaining.
