This question was asked by someone over on "That forum which shall remain nameless", but there are very few people looking in the 98 section over there so I decided to ask here 'cause I'm curious.
The guy was having problems with RT running off HPA (won't cycle after a couple of pulls) but it was working fine on CO2. His HPA tank is correct output pressure.
Any ideas why this would happen? Is this a common issue?

Rong output pressure...
I have a 98 pro with an R/t and it works fine on C02 and HPA.
Thats the only thing that could be rong....because after pressure there realy isnt a diffrence.

According to the original post it's a high output pressure HPA tank (or at least that's what he thinks). Could this have something to do with the density of HPA (lower compared to the sometimes liquified CO2)?

When I was using an RT on my A-5 and would switch from CO2 to HPA and visa versa, I would have to retune the RT every time. For example the CO was running at about 850psi (had a gauge on my drop forward) and then the Crossfire HP tank was preset from Crossfire to 810psi. This change in pressure would need a retuning of the RT. Once I retuned it for the new pressure, it worked perfectly.
With the CO2, chances are the increased pressure has more blow-back air which the RT runs off of so that is why it seems to run better off CO2.

Forgot to mention the adjustment that would have to be done. Tippy~ |
