RT on/off not very RT-ish...

[dreadpirate]

I just got set up with an RT on/off, which people on this forum (as well as a few mag owner friends) told me would help get me sweetspotting easier than with my ULT.

My normal setup is with a ULT and an 800psi Crossfire reg, which manages 19bps over the chronograph when sweetspotting.

When I put the RT on/off in the valve, I get absolutely no sweet spot. None at all. I can not even fire a burst... not even two shots. All it really seems to have done is make the trigger pull several times heavier.

I have read that this is normal and in order to have it behave reactively I need to shorten the on/off pin. Is this true? I have a spare RT on/off so it's not the end of the world if I go beyond repair with one of the pins, but I would like an idea of how slowly I should trim it down, using what (file, sandpaper, dremel) etc. and what exactly it would achieve.

Ideally, I would want a very effortless sweet-spot to be achievable, preferably in the 13bps range. Any help would be appreciated, thanks

Here is a link that may help you ensure that everything is in specification.

And if you have not already gone here you may want to take a look, it is a fairly complete how-to as well as explanation of how rapidfiring works. This guy is sweetspotting around 34 bps if I recall correctly, but all you have to do to lower the sweetspot ROF is lower the assumed adjustable tank's output pressure, or apply greater pressure with your finger (lighter=faster, heavier=slower) Just to reassure, he also reminds the reader that the automag valves are rated for 3000 psi input max, so putting in even up to 1400 psi will not cause damage, though going to a braided steel air line is recommended for pressures over 850 psi.

I've wondered, does running remote have an effect on rapid fire? I am just thinking that with a longer hose, the tank reg may have to work a little harder and there there is more room for hose flex.
Has anyone done tests?

It shouldn't make much difference because the remote is at the same pressure as what is coming out of your tank and should be recharged just as quickly as your tank reg recharges. Tests would be interesting to see though.
