Just tached my new brillelli 46GT. It is installed on a GP Pitts special.
MenzS 20x8 7450 rpm, JXF 22x8 6300. This is respectively 23.25 lbs (10.57 Kg) and 24.58 lbs (11.17 Kg) of thrust.
Those figures were taken after the second tank only. The GT 46 is the version with a ZAMA carb.
HP should be around 3.6. I'm living at 1200 ASL.
Happy flying to all
