Performance

254MM is back in my possession.  My original intent for the aircraft was efficient performance.  That takes a large number of small incremental improvements to happen.  Here's a list, in order of bang/$


  • Engine Cowl Ramps - CHTs run high on the aircraft and ramps are one of the easiest ways to drop them.
  • Balance the fuel injectors -7% fuel burn
  • Aileron alignment - The ailerons are not in alignment, one is set too low.  This is causing a pretty significant out of trim and excessive trim drag. +4% aero
  • Gear leg/fuselage intersection fairings - I have them, they just need to be glassed in. +3% aero
  • Firewall exit ramp - Improves cooling and adds speed. +1% aero
  • Add elevator root caps +2% aero
  • Rebuild canopy - The canopy is set far too high, it could be much more aerodynamic +6% aero


Baseline performance: 140 KTAS @ 7gph 

Target Fuel: -5%... 6.5gph

Target Aero Change: 15% (cumulative)... 161 KTAS
