I saw a review of Cyma's CM028 - AK47 replica. And I thought I must write here something, because the review is bullshit. But what to expect when the replica is reviewed by someone who sells them, not by someone who only uses replicas!
Around 2:12 the guy says the following:
Not only will bigger and more powerful battery increase the rate of fire (...), also increase the range and accuracy up to 5 to 10 per cent.
Come on! The only thing that changes when you supply 9.6 volt current instead of 8.4 volt is the engine speed. The engine revolves faster, the gears in gearbox revolve faster, the power spring gets compressed faster. But the energy delivered to the piston by the spring does not depend on how fast the spring was compressed! So no matter what battery you use, the amount of compressed air that will push the BB through the inner barrel remains the same.
Well... there may be one case when it isn't the same. If you connect 12V battery to stock replica, the engine may try to compress the spring when it didn't decompress itself fully. The engine may revolve so fast that the next gearbox work cycle will start before the piston reaches the cylinder head.

Come on... Is this post really so uninteresting that noone has anything to comment? ;p
