Okay, I'll bite: please define "stay on top of them."

I have no worries about the quality of the model itself; my concern is that I do NOT want to have to be constantly messing with the retracts to keep them functioning.

I have no problem with a requirement to take time and care setting them up; hey, I fly helicopters too, and care and patience in set-up is the name of that game.

But if these mechanicals are like the other set of inexpensive mechanical retracts I had, and need to be tweaked, adjusted, straightened, etc., after every flight or two, then that is what I'm trying to avoid.
