REFLECTOR: Weight & Balance

[Scott Baker]

Let's remember that Kurt's aircraft is a model 173, which has different W&B numbers than the Velocity Standard. The most recent published POH puts the 173 Aft CG Arm at 122". The most recent unpublished factory recommendation is 123". Thanks Wim, for your real-world experience and observations of flying the 173 at 123". I strongly recommend that 173 drivers approach the 123" Aft CG Arm during flight testing with due caution. Expect very sensitive pitch controls (that can easily lead to PIO ...pilot induced occilations). Smooth air and a smooth hand are needed when flying at 123".

>> Well, I just finished all the weighing of my 173 FGE. I am running all the numbers now to see what I am dealing with. My manual does not show what the Empty CG should be for a 173. I looked on the Velocity website, and I don't even see the W & B section in the on-line manual. Anyone have some reference numbers or point me to where I missed them?
