My thanks to the likes of SAS and JJ, one never stops learning and to discover several things whilst compiling this thread was amazing. First was that there are singles out there that drive the TR from the engine (AS350) - why Aerospatiale built it this way astounds me as it inherits more problems than it resolves and secondly, that some helos can survive a total loss of tail rotor structurally and still survive - thanks to all.
However guys, this particular thread was meant to be FOR BEGINNERS
- to gently break them in and you lot have descended on it with technical descriptions of this that and the other which is enough to put any R22, Enstrom pilot off for life!
By all means correct or add or whatever but please please please KISS guys, so the sub 500hr makey learney doesn't get blown away with the complexities of beeping back on one engine to reduce TRE so as to follow fences for half a mile whilst yawed off differentially in auto reading the oxford english dictionary
KISS
