Wow, these videos show some insane power of the new MSH Protos 500 electric helicopters. It looks like this one is going to give CYB and his Rave a run for the money.
A few people have built them and they look good. A few reports of the tail pulley failing but seems as if the manufacturer is responding well to the issue.
[don't even ask what this veoh.com player is. looks like everyone is in the video serving game now.]
