Rich,
I am sure Tim does not mind you making changes, if it would help with a problem. Why do you not add this line 'empty_weight_CG_position= -0.060, 0.000, 0.000' and then use my tail hook settings and see what happens. The '-0.060' is just enough of a change (with this model) to cancel out the pitch (nose over) even if you hold the brakes (now 1.0) and give it full throttle. Try it as original ('0.0') and see what happens. Not sure if Tim will try to use any of this, as he might not 'do' carrier landings of war birds (and a tail dragger to boot). Or jam it full throttle with brakes on, either. But there it is, in black and white. Use it or loose it. What can I say.
I love to fly models and expect them to fly 'right'. If they don't I investigate and make the necessary changes where needed, somtimes determined by trial & error, and sometimes by pure 'logic' (ie: by thinking outside of the 'Airwrench' box). Then I offer my findings here and hope someone can come away with a smile after having some success after using my mods. And that is ALL I want/expect. Your smile.
