Cheers Ian, think the reason you get a noise like that is due to the camera attached directly to the stock which you then get the motor and gear sound travelling through the plastic.
Rate of fire is above a SOPMOD on li-po which I was happy about! just started using .25's in this video and is achieving a great distance aswell as accuracy.
great fun but the dark video was a little bit lost. doesnt quite capture the full effect the torch gave. Just playing with camera angles too so next time will have a different one.
