I think I did get out my big squeezer and dimpled that line on top the 1007 a. As I remember, the skins would have fit better if they were countersinked, as long as you had adequate metal there. My wings are out at the hanger so I couldn't look at them. Maybe someone else has some more recent recollections. Dr Fred. wiring up center console.

WOW! Great plane! What a beast! Handles almost hands free. At hi cruise, it needs a little left rudder to center the ball. Total time 1.75 hours! All went well with only a few minor problems to work through. Idle EGT on #6 cylinder was high and was found to be an out-of-round intake pipe causing an air intake leak Late in first flight, the #2 CHT suddenly went high and was later traced to the CHT probe. The plan is to continue tomorrow.

They might have had a slightly larger capacity. They were black anodized - not gold (Kool). They remain the choice of Lancair builders who are upgrading performance(but that is not enough after Matco's are installed). They have a Helper spring on the outside of the shaft to assist to a Return to No Brake mode. I have suggested to Paul that a 1/8 Elbow fitting added at the firewall would assist Retro Builders to redirect Scat tubing away from his fulcrum arms. He is considering that. The DHI lines are a Big Deal. There have been lots of upgrades from Nylaflow lines. Lancairs come across the fence 50% faster than a VANS (in flare) and more than 60% heavier (with WOW). That all works into the math calculation for rotor mass, pad surface area and pressure of H-5606. When the brakes get mushy and the field is short, the operators look to improved performance. Lancairs need hard surface and 4,000+. Tim wanted Dirt or Grass and 2500 feet. When there is a cliff, trees or a dogleg, the improved braking becomes a bigger deal than just HP. Tim went with dual calipers and 75% more rotor mass (I think 0.435" rather than 0.250"). I have a firm back east, that grooves my rotors on the BMWs. The groove is set to minimum caliper width so it is also an indicator line for rotor replacement. It allows outgassing from the heated pads to dissipate and return to conversion of energy mass into friction and heat. It is the heat dissipation that is the science. Hoyt Fleming put NACAs ducts on the side of his wheel pants and cooling ducts internally like on NASCAR vehicles to direct the flow over the rotors. I told John Jessen it is the heat buildup that caused NASCAR to go to a cool down lap to avoid warping of the rotors from uneven cooling. Seems the pads were retaining heat and contributing to rotor warp. It is much like the respect pilots should have for turbo oil and a cooling cycle before shutdown. Short taxis should be avoided on hot days. Land long, taxi back, save rotors and $$$.
