Evil,

One problem many have had is with the fill valve. Mine didn't work right. If you add another spring (stronger one) it will work fine. I used one from a ballpoint pen (cut down) and it was fine. I also had some leaks from the more rigid tubing they provide with the retracts. I ended up replacing mine with the silicon tubing like Robart uses (mostly because I didn't like how rigid the stuff was ). The retracts themselves are great and from what I can tell strong, after a couple hard landings with the Bearcat.
