(Richard Pike) ________________________________ Message 1 _____________________________________ Time: 07:18:22 PM PST US Subject: Kolb-List: Re: thrustline more negative or down. From: "Richard Pike" Flew yesterday evening and again tonight, perfect conditions, took some pictures, got my head on straight about my engine/gearbox/prop setup. Here's how: Yesterday's flight I set out to film the horizontal stab/elevator at 5000, 52k, 54k, 56k, 58k, & 6k rpm. The elevator at 5k & 5200 rpm was slightly down - 1st pic. At 5600 - 6k it was in line - 2nd pic. Thinking about the effect of going from the B box/electric starter & Ivo, to an E box w/electric starter & Warp Drive - I am thinking I moved about 5-7 pounds of weight rearward about 24". So now - with moderate thrust at 5-5200 rpm, the slightly rearward CG requires drooping the elevators a hair, at higher speeds/more thrust, everything is about where it needs to be. Along with that, tonight I gave it a real workout, cranking and banking, rapid throttle inputs, back to zero throttle while cranking and banking, a lot of aggressive maneuvering, and it felt really good. Then I set the throttle at 5400, which works out to about 60 mph, and just flew around until it go so dark I had to land. 3rd pic Greaser. Life is good. Quit worrying about it and just go fly. -------- Richard Pike Kolb MKIII N420P (420ldPoops) Kingsport, TN 3TN0 Forgiving is tough, being forgiven is wonderful, and God's grace really is amazing.
