I just finished my first speed build kit, (Tiny Trainer) and I ordered it in the water resistant foam board version. I am not new to the Adams DT foam board but the new water resistant stuff was quite a bit different to work with. First of I noticed that the hot glue has slightly limited adhesion properties as compared to the regular paper board. In some instances such as mounting the servos, I lightly sanded the foam board before gluing them in. Second, tape is somewhat resistant to stick as well. Now this of course is just my observations and may not be shared by others but as I was building my kit, I was thinking that maybe a video covering the difference might be useful since the new water resistant foam board is now available for the kits. This would be most helpful to us beginners. Thanks for all you guys and gals do! You have made this hobby way more fun and affordable to a lot of us out here.
