Can anyone tell me how to change power settings on Air Wolf ?

I'm pretty sure you cannot. I think the settings are stored in an EPROM and have to be flashed in using propriety software.
At a minimum you'll have to ship back to AOA and pay shipping. If they charge you a service fee for doing this, its worth looking at the heliboard as an alternative, since for a small amount of extra $ you will have a lot more flexibility. Don't worry about voiding the warranty. Its plug and play and you can easily return to a stock configuration.

There is a great thread started by Scott Haroff on AGN describing the board. I got one a couple of weeks ago and its fantastic.
 
"pinwheel87"So if the Heliboard is plug n play and I get 12 power settings right ? I know its not waterproof but is it at least water tight for shooting on misty days?



Some guys post info without real knowledge or facts. I see these same guys post in almost every thread with some or little knowledge. When Daystate states the air wolf board is water proof they mean it literally. Daystatre thought people would not buy Air Wolfs because of the electronics so they offered a full 3 year warranty on Air Wolfs when they were introduced. Unheard of in the airgun industry.

As far as the Heliboard being waterproof it is not, contact the seller before buying he offers a couple of ways to seal the board from water. Its not waterproof but you will be able to shoot in the rain if you choose.. That said the seller has sold hundreds of the Heliboard boards and not one has come back due to water damage.

I could not find the original Air Wolf waterproof article but found this: http://verminhunter.com/viewtopic.php?f=22&t=7686
 
"pinwheel87"Regardless of which board output on the gun will be the same on the Max-Min settings correct. Do I gain that much more for the 2 extra Ft/lbs when punching paper ?
Not sure what you mean by Max-Min settings for the 2 boards? Typically for the stock Daystate board the Min is just a few fps less than the Max, unless you ask them to set it up differently (min was 19 and 35 ft/lbs). For the heliboard, there are 12 power levels, with the Min much lower than the Daystate board, and the Max just a little higher, though that might vary from gun to gun. If you are interested, I just posted some chrony strings in the original heliboard thread started by sharroff.
