    Heliboard

    Or get the Daystate transducer. Probably would screw straight into the plenum gauge hole.

    Heliboard

    I’m not sure about that. I had a DW and it has a regulator. I think the RW and AW are the same. I didn’t have the valve out my delta Wolf but from pics it looks about standard, say 8mm. A simple calculation shows it should be possible to get more energy from an electric system than most...

    Heliboard

    I recon my (normal) hammer when cocked has about 0.5 J energy. A 2000uf capacitor at 70v has 5J of energy. In theory there should be lots of spare energy even if the solenoid coil is quite inefficient. I cant find any info as to whether for a capacitor dump, more thin windings or less fat ones...

    Heliboard

    Hi guys, just found this thread. I have contacted the guy that makes these and waiting to hear back. I would like to try to get it fitted in a RTI Prophet. I know there are many challenges, like no LCD or switches on the gun for programming but Im sure its possible. Right now I would like to...

    RTI Prophet II standard valve 'upgrade'.

    After a few months of struggling with the P2 with poor velocity spread and leaks I decided to have a go at fitting a standard type valve. The new valve is turned for PEEK with hardened 3mm steel rod. Other changes to make it work - Balance tube part drilled out to 6mm, O ring removed and 1mm...

    RTI Prophet III

    That last gun is not the same as the P3 which looks like a slightly updated P2

    RTI Prophet III

    Apparently seen at some show. Not yet on the RTI website. It seems they may have dropped the troublesome (P2) balanced valve and gone for a more conventional one.

    FX Ballistic Chronograph

    I think this thing still needs some work. Check out the speeds.

    RTI Prophet 2 Valve issues

    I don’t see a problem trying the RPB barrel on a P1. Yes there are a high proportion of P2 owners reporting problems. If there are ones who are 100% happy they certainly don’t comment much.

    New video for Prophet owners

    This is the other half of the main valve. It helps a lot to polish it.

    New video for Prophet owners

    Didn't actually dissemble, inspect or polish the main valve which in inside the 'cup' part underneath plastic disk. It could be scratched like mine was.

    RTI Prophet 2 Valve issues

    Unfortunately I’ve been basing most of my speed spread comments on the FX radar. Recently there seems to have been a bit of a backlash and comments that these are producing inaccurate and wild results. When I measure with the Skan the speed spread is way better (10 compared with 40). The gun is...

    RTI Prophet II — Powerful and Tough — a Hunter's Dream

    If my internal block measurements are correct the valve will be long enough

    RTI Prophet II — Powerful and Tough — a Hunter's Dream

    Ill probably have a go at modifying the valve with a new brass one and balance tube. The top one is the 3rd RTI version of the valve.

    RTI Prophet II — Powerful and Tough — a Hunter's Dream

    The inside of the cylinder didnt change. The original was always smooth but the replacement was terrible from new. Im now using the original balance tube with the new valve.

    RTI Prophet II — Powerful and Tough — a Hunter's Dream

    So apart form the aluminum paste inside the old tube, it looks quite smooth right? Check out how the new replacement looks. WTF.

    RTI Prophet II — Powerful and Tough — a Hunter's Dream

    The spring inside the balance tube has sharp ends and eats its way through the back of the aluminum valve. The debris from this accumulates inside the tube and prevents free movement of the valve. Unfortunately the new valve assembly still had a razor sharp spring end against aluminum so it will...

    Best slug for .22 Prophet Performance 2

    Ive been through many slugs with the P2 with RPB in .22. Most weights in H&N and a few in ZAN. It didnt like ZAN at all or JSB slugs, or ANY pellets. The most consistent for me is the H&N 27gn in 217 followed by the 25gn. They dont like being pushed past 950fps and start to open up. There may be...

    RTI Prophet 2 Valve issues

    This is why I really like 'Aim Small'. His groups are more 'real world' than many YT posters. We are all a bit guilty perhaps. When we occasionally get an amazing group we want to share it like its normal.
