So I failed.
A nerf Rayven was going to be my first Lipo powered flywheeler I modded myself and I was hoping to make it good for HvZ, also so I can fling foam at younger nerfers without feeling guilty. This is a great cage, but I believe it is why I failed at staying under 130 FPS. I was flinging around 160-180fps with revamped fangs and a 2s lipo. The cage has a rather high crush on the dart is my understanding. High crush can lead to higher fps numbers.
I got this thinking 1 would hit 140 fps with fangs on 2s. when I was down I crono ed it and I was hitting 184 on average. great if you want high fps bad if you don't. I was in the low setting too.
