Also missing Amber by 311 . How do we report these things to Harmonix ? <| sep |> So you see how he puts the helicopter on it ' s side , and then flies along like that in a more or less straight line ? You can ' t do that , that ' s not how helicopters work . Enter the gyro . Now I ' m going to skip the wildly complicated control setup needed to make this work , and just assume you don ' t really care about that part . The part that ' s interesting is that the gyro isn ' t just a stabilizer trying to push back to center , it ' s controlled by the remote based on the normal inputs and what it ' s actually trying to do is keep the heli STABLE , not flat , not up , just stable . So whatever attitude it ' s holding , the gyro tries to keep it there . Without one most of those tricks aren ' t even possible . For instance , if you put the heli on it ' s side 90 degrees , it would naturally try and fly towards local up , which is now sideways . The gyro stabilizes this effect , and combined with blade pitch adjustments automatic and super good control , you get normal flight , while tilted . This is how they invert as well . The blades just flip over automatically to continue providing the thrust towards the ground . It ' s also worth noting that RC vehicles often have massively high power to weight ratios . This heli probably exceeds any real helicopter by 10 x in that regard . Maybe a lot more . I have a revo 3 . 3 monster truck with an upgraded engine system in it . It ' s pushing 10 hp right now . It only weights 20 lbs . That ' s a pretty damn good ratio . A real monster truck is more like 1000 hp and 34 TONS . That lets you get away with a lot of cheating .
