I just completed Madness #3, this time deciding on the YS63 for motivation.

I have not really found a need to put my Yamada motors on a stand. The cowl on the Madness is very open, so today we went to the show with a gallon of CoolPower 30% Heli fuel, filled her up and prepared for the first flight.

Prop is an APC 14-4W with a OS #F plug. I ran the starter for 6-10 seconds to get the fuel flowing and the tank pressure up., lit the glow plug, and the motor started for it's first time on the first back flip. I turned the needle in for a nice smooth soundnot quite to peak and then backed it out a half turn. I pointed the nose upwards, and at about half throttle I let go, right into a fairly rapid climb for a few seconds and then some gentle turns and loops and rolls to allow the motor to turn and get some air flowing over it.

After three flights with awesome and flawless performence, I turned in the idle needle about 1/4 because it was slowing down too much for my taste after removing the glow heater. The idle smoothed out a little but mostly, the idle did not slow after removing the glow driver anymore.

I have not checked the RPMs, but my ear tell me that the motor is turning where it is very happy, and the Madness leaps into a vertical screaming climb from a hover or backing decent. Hovers with the Madness occur near 1/4 throttle. Entering flat or rising spins takes throttle management as full throttle pulls the airplane out of the manuver before it established nicely.

OK, another perfect Yamada. I am very pleased.

My trick to making it run so well. First, use the CoolPower 30%. Then an OS #F. Don't touch the regulator or low speed needle before the first few runs (as in do not fiddle with the motor while admiring it, just remove it from box and mount the sucker), and then only move the idle needle if TRULY needed. Place the high speed needle per the instructions. Use a 14-4W if you are funflying. It's another "motor for dummies" with performance for professionals. Me, I always need the easy to use motors, enjoying only to fiddle with other parts of the airplane and building.

Two big thumbs up and my toes in the air to boot!!!
