Disarray;
What plane are you mounting the Area 51 on? I set up my Area 51 on Lawn Boy, had to adjust the high speed jet to turn the motor up, adjusted the low speed, then tweak the jets. Flew the EF Extra 300. It pulled the plane absolutely great. My plane weighed (Lost the plane on the 4th flight) about 17 pounds. I even hovered it on the 3rd flight and it pulled out with ease just over half throttle. I am currently building my new extra and Milton replaced my heavily damaged motor per the warranty. I got instructions with my motor, you just got to watch these Georgia guys. Seriously, I know RC people who purchased other motors and products from Milton and all have very satisfied.
