Tain't, you imply by the use of the word bunt that you are pushing the cyclic forward as well as lowering the lever which is a very bad thing to do in a robbo. Without positive G applied the rotor can do it's own thing due to lack of control power and the only thrust produced is by the tail rotor which wants to roll the aircraft. The usual consequence of this manoeuvre is to introduce the main rotor to the tail boom with obviously unpleasant results. The other reason for not bunting is that it will decay the Nr - just the opposite of flaring to increase the Nr - a low level auto from 100 kts is a good way to show this - lower the lever and flare to wash off the speed, possibly gaining a little altitude then at 60 kts push the stick forward briskly to stabilise the speed and watch the Nr decay.. .My advice in the high power climb would always be to lower the lever as quickly as possible to conserve your rapidly decaying Nr - then consider turning and or flaring some speed off to recover the Nr to limits - pushing the nose down to gain speed just increases your RoD and if you dont have much height left will just make the EOL more interesting. Out of interest I think the constant attitude EOL would be survivable in an R22, just not very pretty.
