4 ea JR 2721 analog servos. You know the specs, if not, they are easily found with a Google search.

I bought 4 new case tops, as the originals were wore out. Its a typical replacement item after a year or 2 of flying. I will include the old case tops. The tag on the old case tops say 4721. The 4721 was a plastic geared servo. So, I presume these 4 were upgraded from plastic gears to MGs at some point in the past.

They all work. I just want to move them. Buyer pays shipping, included in asking price.

I will do a straight trade for a Falcon or Mejzlik prop, 28x10 2b. I would prefer undrilled. If it is drilled, I would prefer it to be drill large 150cc class bolt pattern. Again, just preference, not necessity.
