In the photo below I applied Plast-Aid to a brand new Phantom 3 Pro by taking off the shell and motors from their mounts. I was worried from all the reports of shells cracking on new phantoms. I mixed up some Plast-Aid guessing at the amount that I would need. After mixing it very well I applied it as seen in the photo making sure to apply if all around areas that may crack based on photos I’ve see of others who were damaged. The Plast-Aid allows you about 5 minutes of work time, up until about 3 minutes its very runny, similar to a thick glue, at about 4 minutes it begins to firm up and at about 5 minutes it becomes pretty firm and un-workable. At about 8 minutes it begins to get very hot and starts bonding with any plastic it is in contact with and after about 12 minutes it has finished the bonding process and cools down. Plast-Aid is VERY strong and durable. I would venture to say it is stronger than the shell material by a factor of 10…. Very Strong Stuff. Plast-Aid is available here I applied Plast-Aid around all 4 motor mount areas just like in the photo and have not seen any cracks or hints of cracks what so ever. I highly recommend it.
