So I got bored over the holidays and decided to mess around with my trainer. I don't really fly it much since I only got it to let my friends fly on the buddy box. So I decided to fabricate a bomb drop system for it to use at the local feld. I designed it to hold small flower bombs or golf balls. I figured this was as good a forum to put it in since so many of this forums readers have trainers. This just goes to show that if your trainer survives the flight training stage it is still useful! I fabricated this set up out of some scrap balsa and covering material. I used an old servo I had laying around to open and close the doors. I also used some really thin piano wire and some small pieces of PVC for door pushrods and control horns. It is not perfect but not bad for my first try!
Here is some pics and a short video clip I uploaded.
