Default G-26EI

New Zenoah G-26 EI

Installed in VQ Cap10b 1.20 size scale arf
Model weighs every bit of 12lbs.

First run
Stock needle settings
Fuel - Premium unleaded 93 octane Shell Gas.
Oil - Penzoil 32:1 Aircooled two cycle oil
Propeller - Graupner 3 blade 15x8
RPM first run 7700
Second run APC 16x8 Pattern Propeller RPM 8400

After three flights the Graupner three blade went from 7700 to 8000 static on the ground. Thats a gain of 300 RPM
Flew a Menz 15x10 three blade just for the heck of it and turned 7000 on the ground but died in the air. (not broke in enough)

Fourth and fifth flights RPM up on the Graupner 15x8 at 8100, idle at 1600 (it will go lower) High idle at 2000 rpm. I did adjust the low in needle at about 1/4 turn in (lean) to get a better accel response. Temperature meter was reading 125 to 126 degree F. on the ground static , I need to take some readings immediately when I land to get a better idea of what flying temp is.
