Strange sound on my Nerf Hailfire-what is it? Answered
Hello! Nerfrock' here! Just recently I decided to fire up my good old Nerf Hailfire again-but this time, something was different. When I pulled the acceleration trigger, the motor started up fine, but when it got up to full speed, it started making this wierd vibrating
sound as if it were a motorcycle being pedaled up and down. Even with all my Nerf modding experience, I am baffled... Does any other nerfer (or anyone in general) know what it is? Do I just need to change the batteries, or is it something else (I hope not) .
