Speaking from a student/e-cocker/CO2 point of view (been there, done that, bought the air system
)
My views go like follows:
Officially, the front 5-way solenoid used up front in the race (the e-blade use a very similar one
) cannot be run on CO2 - for the reason that Beaker said, about the little buna o-rings inside absorbing CO2 and swelling, thereby jamming your solenoid.
I ran my race for just over 60,000 shots on CO2 before I moved to air, and the solenoid is still running fine.
I did have a problem in one game which prompted me to buy my air system, and I say you'll do the same thing - after caning 5 pots at a max RoF of 11 (my revvy was knackered, so load time was loooong) my CO2 tank had frozen down so much that there wasn't enough pressure to recock the marker, never mind fire it.
The following weekend, the same CO2 bottle (without being refilled) had enough gas to shoot another 8 pots (slowly, so as not to freeze it).
In summary, yes, you can run your e-cocker on Co2, no, the manufacturer probably wont support it (will say out of warranty if you try and get it repaired), don't play at the back, cos you'll do a few pots then have a cold useless marker, and no, i'm
not going to accept any responsibility for you knacking your solenoid by running it on CO2
