No personal experience of other air-systems; only recently moved from CO2
E-Blade Cocker (s-b fade), Black magic inline reg, 16" Freak, 12v leccy Hopper & Conquest 03 air.
Solid build, easy maintenance, on/off switch, air filter, dual gauge.
None so far...
I've been running my eBlade with CO2 for almost a year purely because I couldn't afford a decent adjustable air-system. After a while searching I found MacDev.net :
First off, the price is good for an adjustable system - I paid around £280, including delivery, for a 68/4500psi. Compare this to most other 'named' brands and you'll see it's a good deal.
The design is very simple - there's a large on/off lever at the front of the bottle which is itself mounted into the output-pressure adjuster. To change the output pressure, flip the switch into off position and turn the dial. This can be easily locked for tournaments.
On one side of the reg are two dials - bottle pressure and output pressure, and on the other side, the fill nipple (with micro air filter inbuilt), and the air-out fitting.
The mounting rail is a standard Air America dove-tail fitting so you should have no trouble getting a decent drop-forward for it.
As for performance, I have used this for two all-day walk-ons and have had no trouble whatsoever. The fps has stayed in the mid-nineties all day with only +/- 3 fps inconsistencies.
The recharge rate seems to be very good and I didn't notice any drop-down either.
Maintenance? The supplied manual is small but well done, and contains what little info you need to strip the reg down and service if needed. At first glance it seems very simple to do.
This probably isn't the best air-system money can buy, but it's certainly an excellent one regardless of price. You should definitely consider getting an inline reg if you don't allready have one, but you can't really go wrong with this!
Since writing this review i've had a couple of problems that are probably just general wear and tear but you may want to know:
The fill nipple blew - the semi-circular ring that holds the internals came loose which allowed the them to turn sideways. Lost one of the bits when dismantling. Tried to put a 'normal' nipple back in but these have slightly longer threads and the reg doesn't like this and the filter spring in at the same time (presses filter too tight hence interesting noises when filling) which means no filter which probably lead to the next problem.
Generic air leak from on/off (?) Have replaced all o-rings and still leaking - seems to be coming from main valve. Could be due to crap getting in now the air filter isn't in place. Have ordered from Australia who will contact Sweden who will then send me the rebuild kit as you can't order direct from Sweden easily as they don't take plastic... (aaaahhh!)
Got the Upgrade kit - contains all the o-rings needed and includes the 008 upgrade kit which basically replaces all the main internals (not piston) with newer designed versions for better airflow at low and high outputs. You also get the fill nipple internals and the new springless cuff.
Needless to say it fixed the leaks, but even if you haven't experienced any problems with the regulator I recommend you buy this kit anyway! It's only 20 aussy dollars so you can't go wrong!
