i did the same thing, except i had a black dragun lcd trigger frame and i put it on my spyder and it would do that 1000 bps action thingy, lol ( like it has no air) so i went home put the original trigger frame on the black dragun and i went to test it out and it shot fine, i never was able to crono it (ran out of paint playing with it on the test range lol

) but thats the next thing im going to do. so that might be your problem, and what i thought was my spyder spring couldn't keep up with the trigger frame or something this may be totally wrong but i got it to work now. so i hope everything works out alright.
