RE: SIG Kavalier Build
I only installed a Fox .40 delux on mine. Its still fast with an 11x6. My ailerons have too much throw. Mine does 720 degrees/sec. I installed a STOL tip design. The tips are carved with a down turned arch. I used the standard LG location and balanced with only the battery and RX. Its been flying for over three seasons.
Hope you have as much fun with yours.
