The 80 hp version has 2.27, the 100 hp version slightly different. A variable pitch prop is the only way to go in the Pulsar if you want to maximize performance. The 64 GSC in flight adjustable is a good choice. My XP has about 1000 h on it with this prop. Performance (measured/estimated): Best rate of climb about 1050 fpm at gross weight, sea level, standard conditions. Cruise speed: 125 KTAS at 3.0 gal/h 133 KTAS at 3.5 gal/h. 138 KTAS at 4.5 gal/h Range (18 gal total): 4.8 hours plus one hour reserve at 3.0 gal/h --> 550 nm no wind 4 hours plus one hour reserve at 3.5 gal/h --> 500 nm no wind 2.8 hours plus one hour reserve at 4.5 gal/h --> 372 nm no wind Take off distance: <1000 ft ground roll at gross weight, sea level hard surface 1500 ft over 50 ft obstacle Landing distance 1500 ft with slow approach Sonja On 12/27/13, philb wrote: > > as i am thinking of getting a pulsar and would like to optimise prop > gearbox ratio for perfrmance so was wondering what u are all using > prop wise diam and pitch > gearbox ratio > static rpm > climb rate one up > take off roll one up approx > and cruise speeds at say 5000 rpm 5600 and flat out > it could even become a sticky > phil > > > Read this topic online here: > > http://forums.matronics.com/viewtopic.php?p=416244#416244 > > ________________________________ Message 2 _____________________________________ Time: 09:20:32 AM PST US From: "Keith Palmer" Subject: RE: Pulsar-List: 582 prop and gearbox ratio r u using Hi Sonja, I got hold of GSC a while ago(different team)and he said they had discontinued the manufacture of the in flight adjustable, but still had the jigs, but things might have changed again. I had two, one spare, they serviced my first one and offered me the new version for a very nominal fee. Regards Keith D.
