About Graupner Props. I just received 2 3 bladed Props one 12X8 for one of my smaller planes and a 15X8 for my bigger plane. Great looking props whith solid hubs unlike the MAS props which is a big plus.

But what i'm wondering about is the Important Notice i read on the box they Come in. Which i won't retype it all just the Part i'm very curious about and have never seen or heard of till now whitch states: (IN ORDER TO PRESERVE THE STRENGTH THE WATER CONTENTS MUST STAY TRAPPED IN THE MATERIAL)??For that reason they should be stored as cool and as moist as possable?? A lack of water content can be compensated eighter by putting propeller in boiling water for a short while or buy submerging it in water at ambient temperature for a couple of days??

First of all how Can you tell when it is lacking in water content and second it's Fiberglass which is reinforced Does it really need to have water content?. I just found this information intresting as i have never seen this with any other propeller. When i attempt to drill it will it squirt water out or have a seeping or sweating. lol
