I have a couple of questions for the crown owners out there. 

What's the point of the transfer port adjuster wheel if each calibre barrel has a different transfer port size? 

I'm about to pull the trigger (so to speak) on another FX royale 400 in 22. I love the 3 stage power adjuster on the royale but would love the bigger magazine and the ambidextrous stock of the synthetic crown. It seems a bit weird having a transfer port adjuster for calibre change when each different calibre barrel has a different size transfer port anyway.

I guess my very direct question is . . . . . If I buy an FX crown in 22 calibre and tune it for 30ish foot pounds on the largest transfer port adjustment (30 cal setting on the wheel) will going down to the 2 lower settings perform the same as a Royale 22 on the 3 different settings? I like to change between them regularly, depending on the pesting/plinking situation at the time. Eg. I have very important uses for all three power levels (30 - 19 - 11 fpe) and they are very repeatable on the royale. Just wondering if the Crown is just as simple and repeatable and similar velocity reductions using the "power wheel" ? 

(I have an Impact X and the HST power wheel does not have enough adjustment for my uses.) Eg. I have to use the valve travel adjuster to lower the power enough for shed work and it's just too much hassle and not as repeatable as the Royale power adjuster. 

I would love to hear from someone who owns both the Royale and Crown and has a chronograph to test this. Any information would be appreciated.

I understand your question, I own a .25 FX Crown. Transfer port settings are just like a FX Royale’s just a big, medium, small hole. 3, 2, &1 or .25/.30, .177/.22 & Low all the same. You could still get the 30fpe and two lower fpe power settings with a .22 FX Crown by using a combination of the two external power knobs (Transfer port & Hammer spring adjuster). The transfer port works exactly the same as the FX Royale and other FX airguns. You actually could dial your fpe in at many more than just 3 settings the way the Crown works, that’s the beauty of the design! A FX Crown owner could set their rifle up for many fpe powers, up or down. Using a combination of regulator, transfer port, or hammer spring settings. With the regulator set at the factory setting. For example one could set transfer port dial on .25/.30 and Max on the hammer spring adjuster and achieve 33fpe potentially. Then, dial the transfer port down to .177/.22 and get 30fpe. Then move the hammer spring adjustment to 3 and possibly get 20fpe. On Low (transfer port dial) or maybe 1 (hammer spring dial) shoot at 11fpe. More power and velocity options in between those settings as well. You can tune a FX Crown to many more fpe outputs than you could a Royale externally. With a chronograph, pellets, and a air source the owner can basically repeatabily set a FX Crown up almost any way they wanted. Hope that helps and makes sense, because that’s all I got for ya.

I have a hypothesis about this, and it is derived from my AAS510, which like my crown also has a transfer port adjuster. Here is the thing: the transfer port adjuster on the Air Arms doesn't actually reduce your air consumption by all that much. I'm guessing this is because there is a fair bit of internal volume between the valve and the transfer port on this gun, meaning a fairly large high pressure air charge is released into an area before the constriction, thus while the transfer port will effectively reduce flow and thus power, it doesn't offer great air savings. Similar would likely be true if FX had left it up to just the transfer port on the barrel, but by having a secondary adjuster closer to the valve CONSIDERABLY better air consumption on lower settings is achieved. 

Just a hypothesis.

OR? Get a Daystate Red Wolf or Pulsar and use the Electronic settings on which ever of the three setting you'll need. Swap on the fly in less than 1 minute. You'll also save air and increase shot count at the lower power settings.

That's may plan with my Red Wolf anyway. Flip lever, hold trigger, cycle setting (High, Mid, Low) and done.

The difference in cost isn't that great and could save some hassle on the fly, IMHO.

Don't you need an additional 400$ accessory to adjust settings on those guns? I personally prefer mechanical adjustment, can also be done in less than a minute with the same effects. I know you can switch between the factory presets, but what if you prefer another speed between the set settings?

Good question, I believe AOA has a tuner, for fine tuning the settings based on pellets. I'll be looking into either that or working with someone who has one, once I figure out what it takes. One of the reasons I got the Red Wolf is because it can be adjusted without all the mechanical balancing required. I have the .22 HP and I've only shot a few mags through it. At 25 yards, the Impact is about 0.15 above the target, at med - on point, and at low it's about 0.15 low. Throw all that info away at increased yardage, but I haven't stretched her legs yet.

I'm optimistic that the pricing of the electronic rifles will go down based on increased volume, but I think only Daystate is playing in that market.

The answer to the original question is very simple, you can adjust the Royale but you can perfectly balance the Crown.

With the Redwolf the three power curves are pre-mapped for perfect consistency, 100%, 85% & 65% all you need to do to change settings is a simple trigger pull and scroll, confirm choice and done, 30 seconds tops, no mechanics to mess around with as there arent any, the algorithm in the CPU works it out for you.

You only need the programmer to adjust what Daystate did at the factory, alternatively tell the dealer you want to shoot an 18.3g at 960 or whatever and let Daystate set it up that way at the factory.

Yeah the Red Wolf and Pulsar already have low, med, and high power settings from the factory but you’d need the programmer to tune it down if you find the low power too hot.

However there is a huge cost difference between the crown and red wolf.

Crown synthetic $1600

Crown walnut $1800

Crown laminate $2000

Red wolf $2500 (walnut and laminate same price)

Plus the mags are bigger on the crown so there are valid reasons to pick one over the other.

I'm thinking of pulling the trigger on a .22 Crown this week and was also wondering how to tune the rifle.

If I'm trying to achieve 880-900 fps with 18.13gr pellets and optimizing the reg and hammer spring should the transfer port be set to the .30/.25 selection when starting my tune and the hammer setting maxed out then turn reg to the lowest pressure possible to get these results?

I have owned both a Crown and Royale 400, still own the Royale! Yes, you can find a combination of HST and port setting that should duplicate the Royale. My question, why bother? The Royale is a simple, robust platform with the original ST barrel that virtually never needs cleaning. I can make none of these claims about the Crown. But, if you like to tinker, the Crown will certainly satisfy that need!

My assumption would be opening for the transfer port dial would be sized to the larger caliber port as not to add additional restriction, ie. the . 25 .30 would be sized to .30 and the .177 .22 would be sized to .22. Low would be less than the .177 if they wanted it to make a difference in power.

If that were the case one wouldn't expect much if any power increase running the .22 or .177 on the .25 .30 setting unless one had opened the port on the barrel barrel sleeve.

On the other hand if you opened the port on the barrel sleeve you could tune the .22 for the power you wanted at the .25 .30 wheel setting then move to .177 .22 for quickly reducing the power.

Keep in mind, on a regulated gun a valve restrictor generally reduces power and efficiency.
