Metadyne Thumper/Phoenix Redux

[Loophole]

Same!

Was that the fix for the old one? If that’s the case I will just drop reg pressure on my on my powerhouse they are pretty consistent. I wonder if my palmers Cart reg would work on it if I drop it down to 300 PSI as well. Or possibly a In grip LPR like what they do with mags maybe an option to if it’s just a regulation issue.

Looks like it needs to be pre regulated to 300psi like the original. If the Nova regulator are available separately, that would be a good option to keep the gas thru grip. Not sure of the Nova regulator operation pressures.

I’m not worried about it. It was a fairly inexpensive purchase. It’s unique enough I will work around its quirks.

I actually didn’t yet! I went to Florida on a business trip, came back, and it won’t work. Oiling it would fix it though, up until it kills the valve. I wonder if these were tested in cold climates at all.

Welp, glad I decided not to buy one right away..

It’s cause you used oil you SINNER

I'll be curious to see what the tinkerers who had success with the thumper make of it at least

[Myrkul]

After seeing all these post, I'm fully convinced that not only did they not fix the original issues with the thumper, but they actively made it worse in multiple areas on top of leaving in all the original design flaws. It's a very cool concept, but I have zero confidence at this point that they will ever develop a functioning marker. This is WAYYYY too big of a miss when it was supposed to be their redemption product. Imo they should gift the design to Nova and walk away. At least the guys at Nova can whip a concept into a product fast as hell and make it work.

I really was hoping for the best, but man it really feels like metadyne didn't learn many lessons if this is the case. Hopefully there will be some more positive news when they hear about these issues.

Follow up: mine doesn’t shoot anymore! Chuff, click, nothing. I believe I know why but FFS it’s the same as the thumper

[RuleOfSines]

Possibly, I haven’t and probably won’t ever put a force fed hopper on it. Its stick feed works well so I doubt I will ever even use the hopper attachment. I got other better open
class pumps for that.

Are you guys getting barrels breaks or is it clipping or breaking in the breach?

Johnny try removing the detents and putting dummy detent between the barrel and body. See if that solves anything for you. Maybe the detent spring pressure is too much pushing the ball up and clipping?

Next time we play bring it and we can compare them side by side maybe figure out what it is.

I think mine is breaking as it enters the barrel, breach wasn't a mess. Might be a result of the ball sitting behind the barrel instead of just inside it when it fires. Bigger bore may help with that. I'll try and mess with it this weekend.

I would say the 450 had a slightly poofier shot, but since both of them had to have the reg cranked to get to field velocity it was still pretty kicky.

[Chuck E Ducky]

Was it a softer shot tho? Next time we play we can mess around with it a bit when you get back. I’m just out of air so I got to get to the field to do more testing. Maybe I can get out this weekend.

[Jonnydread]

I tried a 500psi output tank and a 750psi output tank and there wasn't any appreciable difference in velocity.
