No you need a lot more than that for negative g.
You dont
need a zoom climb for that. It can be a good idea if you like to have room for a longer negative G (well, less short anyway).
For the negative G part, if you have speed just push the stick forward. And before you do it, secure any loose object and clean the floor from things otherways will hit the roof.
The standard in the handheld GPS times was surplus batteries put in some opening in the frame caming loose and flying around in the cockpit before they first stuck in the roof and then fell down to the floor when getting positive G again.
Most engines and gearboxes can cope with that for short periods.
Yup. We had the -1G limit but no set time limit for that, just the natural limitation that it would not last for long time anyway.
So as we probably all know, Chick talks a good fight but didn't invent the manoeuvres, teach himself them nor modify the aircraft in the ways he clamed.
Not saying he is a bad pilot just a self-promoter.
Exactly!
Some of the talking about very advanced modification (” changing the CoG”) involved moving the battery to the position that I think most military BO105 already had.
