All,
Update
Switched from Pennzoil Air-cooled 32:1 to Red Line Synthetic at 40:1
also switched to 3W CF 26x12 two-blade prop. While noise has greatly increased with this propeller the climb and performance have also greatly increased over the Biela 26x10. Turns the 3W propeller at 6000 even. Doesn’t seem like it but this is a great 3D prop.

breakin in my 3w 75ius w/24x10 prop prozinger peak 6.900,and low idle @ 1.800 just run about 2 gallons of 92 octane w/32:1 lawnboy.

Dale,
It took over 7 gallons of 32:1 Penzoil Aircooled to get past break in on my 75I, tried to switch to Amzoil 80:1 at 4 gallons and the motor got hot so I switched back to penzoil. At 7 gallons I switch to Redline synthetic 40:1 and gained RPM and the motor runs just as cool as on penzoil (160-170 degrees F)

No carbon build up, great response no saging at the end of the flight and no sewing machine sound on long uplines. The motor keeps getting stronger. Swinging a 3W 26x11 carbon at abou 6150 on the ground. She really unloads in the air.

3W 4-ever !

THAT'S GREAT, ME ON THE OTHER HAND GOT A LITTLE TIRED OF HAULING THE WILD HARE BACK AND FORTH BIGGER PLANES ARE GREAT BUT NOT VERY CONVINIENT TO CARRY IN MY CAR.BUT I'LL GET RIGHT BACK ON IT REAL SOON,RIGHT NOW MY 3W IS ON IT'S 5'TH GALLON AND STARTING TO LOSSEN UP THE 24X10 ZINGER PROP. I HAVE ON IT NOW SEEM'S TO SLOW IT DOWN ON THE FINAL FOR MY LANDINGS,IT SEEM'S LIKE A JAKE BREAK ON MY EDGE 540T JAJAJA I HAVE TO GIVE IT A LITTLE GAS SO IT COULD REACH THE BEGINING OF ASSFAULT, THINK I'M GONNA TRY A BOLLY 23X10 OR 24X8 SOME PROP. WITH A THINNER BLADE.

Help please. I bought a 3w 75ius off rcu. I am having trouble getting it tuned right. it is turning around 5900 on the ground with a bolly 25x10 prop on 75 to 1 amsoil. It idles at 1900. It has a couple of problems. the transition is good on the gound but when i go to take off it sputters like it is going to die. luckly it doesn't. also at 1900 at idle the plane moves on ground quickly and i cant get it to slow down on landing. my needles are set at 3/4 on the high and 1 1/2 on the low. What do you think?
