Axle not up to spec
Rod/Ratchet pin does not fit securely
Installation took almost an hour (mostly lubing it up). I did notice that the pin used for the ratchet/rod linkage did not fit securely - it fell out without the cyclone's bottom cover in place.
The real problem is the fact that the soft paddles can rotate independently from one another around the axle. This is a MAJOR problem, since it causes missfeeds which can result in ball breaks in the cyclone - this can be a quick end to a good game!
After about three months of usage (and thus three big games), I had my first ball jam/break. Three balls tried to enter the marker simultniously, resulting in one breaking, and two jamming the cyclone. The paddles had to be removed to clear the jam.
I have been in contact with RAP4, who appears to be aware of the problem, but unable to find a solution for it.
Get more opinions before buying the RAP4 complete cyclone upgrade. Perhaps investigate alternate products. I am giving this a low rating due to the lack of support from RAP4. I have had issues with my A5 as well, and within three weeks of contacting Tippmann, I had replacement parts in my hand - international shipping and all! That is how it should be done, especially if you KNOW about a problem.
