its going to be a huge challenge to install the gy611 on the poseidon. its just too big for it. the 9256 will not fit inside the frame. and besides that gyro belongs on something bigger like a trex600. i'm not saying it cant be done but i dont recommend it.
I agree 100% not that it couldnt be done but I would leave the GY-611 for the big birds and stick with GY-401 or the GY-240 for the 450 sized birds..
