Received my remote and 13ci bottle today, so had a chance to do some comparative testing between CO2 and air with my TiPX. I'd seen a lot of people complaining that they're unable to chrono above 250 with the TiPX when running remote, presumably due to the difference in pressure between a 12g CO2 sparklet and a standard HPA tank reg.

Test was using a standard Umarex 12g (for CO2) and a GI Sportz 13ci tank with nominal 800psi output pressure, filled to 2000psi.

Code:
 #    CO2      HPA
 1    283      255
 2    290      248
 3    294      239
 4    294      251
 5    280      245
 6    281      235
 7    296      239
 8    287      235
 9    284      237
10    300      245
11    292      243
12    293      246
13    296      251
14    295      245
15    294      246
16    291      248
17    301      243
18    302      246
19    286      239
20    299      245
Same paint used in both tests, same weather conditions, same chrono (X-radar). Seems that a 800psi output reg doesn't really cut it with the TiPX, with an average 47fps drop over CO2.

Luckily my first magfed game will be Underworld, where the chrono limit is 250fps, but after that I'll certainly be checking out the 900psi output Ninja regs that are being sourced by SAS woodsball: http://www.sasmilsim.com/hpatank.html

are you sure the g.i. sports bottle is actually putting out 800 psi? people running hammer 7's sometimes have trouble getting past the 240-250 fps mark, i'd try another bottle on it or test the output.... another thing you might find interesting is i remember reading somewhere the tpx has a regulator that brings the internal pressure down to run the spool valve as a low pressure marker, when i remember where i read it i'll source it...
