ok i know a lot of people want to combine percival and falconfly so i tried and found out that it works sort of.you will notice next to the latch that keeps the wings closed a L shape part on falconfly.percival or percival vortex can almost slide in there if you put the part were his legs open up in that area.it looks like this.you can also close the wings only to make it look like percival or percival vortex is riding on falconfly
