What I'd like for my CFS and FS programmes are some decent throttles that look like, and operate like, real throttles do - ie moving forward and back rather than up and down.      There are a couple for multi-engine aircraft, but I've only been able to find one half-way decent ECU set for a twin and none at all for a single.
A thousand aircraft available for download and not a decent ECU set among the lot of them.
