Sorry but no pix. It's exactly the same as the popout release. But be careful. I was supervising a new 133 operator and he pulled the hook release with the load "SPLAT" at about 100ft. I always pulled the circuit breaker until I was actually pulling torque.
But definitely beats the collective mounted "bicycle brake" model. What a joke. I know of some crashes because it takes 2 hands to pull the thing.
As I understand it, the only difference between the two is, literally, the engine. A 500C/C-18 and a 500C/C-20 will have the same main transmission so the benefits of the more powerful engine are only felt in hot-and-high conditions.
Yep HillerBee you will over temp the -18 before you over torque it - esp at altitude. And for my money, if I could afford to have a private machine it would be definitely a Hughes/MD model parked in my toy shed. Depending on how much many spare slides I had as to whether it would be a C, D, E model - an F model would be the ultimate.What a beast - power to weight ratio. Screw the Notars - too gay.

You could overtorque it, Just like you could overtorque anyhting if you pull the collective up in to your arm pit. I've never flown a C-18 but I imagine you'd overtemp it quite easily on hot or days or at any reasonable altitude.
I imagine you would have trouble getting parts for the C-18 too.
The biggest difference is the engine support. Rolls Royce do not support or manufacture C18 parts any longer and there are numerous parts that you cannot get for love or money. If the engine needs repairing, you had better look for a replacement. Make sure you buy a C20B powered aircraft or get the right price for a C18 powered one.
I had a hangar full of C18 engines ......sat around for years and nobody wanted them .....they have all gone to the States now prob to go into boats . My French thingy was a 480B ......great little machine ...v simple to fly with no vices and a perfect spot for my dog in the footwell !! Have since sold that and also sold the 500 but looking for another one if anyone knows of one for sale at the right money ..???
It is to prevent resonance that will damage the turbine wheel. It is only applicable to certain third stage wheels which will eventually have to be removed from service. Transients through the range are permitted but steady state operation in that range above 85 shp are restricted to 60 seconds. See RR CEB A 1400, it explains the replacement requirements.

Thank you Gemini, That was very helpful as was the link to the CEB. So the turbine manufacturer has established a limit that pretty much no oldish helicopter has the means to monitor compliance of? It does make purchasing helicopters a little tricky since a normal survey will not give us much insight into previous compliance.
