The stand will hold airplanes from very small profile planes up to 35% models with ease, in fact, we have several customers who use this stand to work on their 42% models in their shop. This is a true rc plane workstation designed to be used on virtually any sized rc model in the shop or at the field.

All the Benchtop Stands will pretty much hold whatever your table will hold, they really shouldn't have a weight issue.
