Brake master cylinder mountings

Good morning everyone. I'm sure most are aware that N34KP was damaged a year ago July. At that time it was the latest incident due to not having brakes, and there are many. So, I'm putting brakes on the old bird this coming winter. I've bought a set of Matco wheels and brakes that will suit my needs...

Re: Stop Engine

I've flown 34KP with a broke crankshaft. It comes down pretty fast dead stick. I was fortunate to have a nice stunted soy bean field below me. I didn't have a whole lot of time, being low (6 or 7 hundred feet). Like they always say "fly the plane", worry about other things later.

Re: cable length adjustment by twisting

Not a good idea at all. Twisted one way you open the lay of the cable and expose the insides to grit and dirt. The other way you tighten the twist and with the flight loads overstress the cable.
