I designed and printed this bomb drop for use on my Parkzone P-47. If you attach another servo horn onto the flaps, mount this payload drop under the wing, and cut a push rod to length You should be able to make it work. For the pins I cut off the z bend end of a set of Parkzone P-47 flap push rods and installed servo horns on the outside of the flaps. Where you mount the base will determine the pin length. For mounting I just put two holes in the back side of the base part and threaded some screws through the wings. I have included the SolidWorks files for anyone that wished to modify the parts. http://www.youtube.com/watch?v=5PLzGexDtTg&feature=share&list=UUQRFnzUWuE9c-lYGHGGb5MQ I finally got the chance to test the system and it works perfectly! http://www.youtube.com/watch?v=E98uVY6TAYY&feature=c4-overview&list=UUQRFnzUWuE9c-lYGHGGb5MQ http://www.youtube.com/watch?v=cPLomJumsuM&feature=c4-overview&list=UUQRFnzUWuE9c-lYGHGGb5MQ http://www.youtube.com/watch?v=VXlno7a_GC4&feature=c4-overview&list=UUQRFnzUWuE9c-lYGHGGb5MQ
