Just a feedback from a ECD test pilot... twist grips give you twice the range needed, so if FADEC is stuck in minimum position, you are able to get the whole twist for full power if needed.
And a really serious question I couldn't find a solution for on T.I.P.I.
The modification for tail mounted balancing weights. Where can we (our company) get the modification done (Other than ECD).
Is the modification really an airframe modification, or is it just "light upgrade work". - I'm not up to maintenance phraseology.
