When I was putting together my build with Roberto he mentioned that he had improved the design of the throttle by making "Mechanical changes on the afterburner detent instead of having to pull on the engine cutoff handles. (correction of the f18 pilot)", so it looks like that design change has been implemented thanks to you.
Regarding the rest of the items (sans the switches, since I have provided my own to Roberto) I will follow up with him to make sure your recommendations/revisions are included in my build. Appreciate you taking the time to make such a detailed posted :thumbup:
Also, FWIW buying the real Otto SL (slider) series switches for things like the speedbrake and ECM dispense have a price of >$250 for each switch...not sure what your budget is, but there are other Otto mil-spec switches that don't look exactly the same but should do the trick that can be had for $50-100 instead. The Comms switch (5-way) was the most expensive I had to purchase, and that was ~$160...all others were $60 or less. The Otto P1 push buttons can be found for <$20, usually.
