As others have stated APE rampage boards rocks. I replaced the W.A.S. boards on my A-5's with Rampage board with Powershot selonoids.. and the difference was tremendous. Much more power (Lift force) from this Board. you can tell a difference from the WAS Board. Ease of programming and changing modes is great. I push mode changes are very nice. Waterproof is an excellent factor. no more worrying bout ir raining out and getting your e-grip fried etc. Battery life has been 3 to 4 times that of a WAS board.. * I have used these board since they cam out in addition to WAS boards so I know. The remping feature is awesome and if you want true full auto not the 1 and 2 trigger pulls then full auto form the was. I recommend the power shot selonoid.. it makes a difference over the standard one that comes with E-grips etc. This board is the best thing to eve rhappen to A-5's.
Conclusion:
This is a must buy for some who likes what E-grips can do on the field.. it's reliable, never sticks on full auto like other boards, waterproof and it's a great price.
