I saw this amazing rc helicopter display on some site today.. there were some pretty awesome moves.. Call me a retard if necessary but how come real helicopters can replicate those manuevers?

Ive seen helicopters do that....when theyre crashing.
In all seriousness I think the biggest issue is power to weight ratio. Its alot easier to make a very light RC copter with enough power to do that. Real helos are much larger, heavier and have to carry more fuel and people. There is also the issue of the crew being able to handle the forces involved. Think of how much faster a missile goes than a plane - if a plane banked and turned at those speeds they could black out/die.
I dont know but I would bet there are some civillian copters out there that can do alot of those moves. I know a CH-53E can do a barrell roll, but it is one of the most powerfull helos in the world, and it cant do it with troops onboard.

pretty cool vid, i wonder how many time that guy has wiped out while learning them. The whole time i was thinking what if real people were in there. lmao, i can imagine them all puking and blacking out
CH 53 can do loops too... love those pigs. I was in HMLA 167 and composite float with HMM 266. Monster beast those CH 53s...

Well, an Apache Helicopter could do "some" of those tricks... although i don't really see what the point of going vertical then moving backwards and forewards real fast would help in a real world situation???
Although maybe some one with real life experience could tell you when it might come in handy???

There are a couple of choppers that can do loops and they can go vertical (tail up/down) whilst going forward and backwards, however they also have a good power to weight ratio. Apaches and Gazelles are good examples. Plus some would be impossible in a manned chopper, I would imagine upwards of 10 G's for some of the more daring ones.
The majority of those manouvers would stress the airframe to such an extent that micro fractures, and possibly visible ones, would be present resulting in a full stripdown. What that means is every panel, every box and every engine is removed and every inch of the airframe x-rayed to reveal the damage caused by such high G manouvers. Most of the frame, boxes and blades would likely be replaced. Also gyroscopes which are used for navigation would basically collapse ("topple" is the tech term) and they are very expensive to fix and they can cost upwards of £250,000 a pop.
I remember one pilot doing high G manouvers in a Tornado GR4 because he thought he was being clever. The resulting work meant the jet was grounded and stripped (engines as well) for 2 weeks while every panel, box and inch of airframe was x-rayed and checked. He was made to stand in 14 hour shifts (no seat at all just water and food brought out to him) and watch the work by his boss due to the engineering officers complaints. I can tell you that he didn't do it again.

He is lucky he got that, exceeding the recommended G's in a training sortie is a court martialable offence and he could have went to the glass house. It is reckless, costly and dangerous to exceed the recommended G's in peace time training because it puts 2 lives in danger plus a £30m jet if the pilot blacks out.
Got a couple of decent stories from my time in. My fave one is the navigator on a GR4 who put a work order in for his "chaff/flare pod non-operational in the O.F.F mode" as he wrote it.
Because it was written on official paperwok we had to test it, which meant attaching a testing rig and testing it for a couple of hours all to discover that the pod doesn't come on in the "OFF" position. And these guys are supposed to be highly educated.
