I use standard size heavy servos, batt, receiver so it will fly nicely in heavy wind. If I used light radio gear it would weigh 3lb instead of 4.
You are not serous about saving a pound on the radio gear are you?
I can't imagine a plane that size weighing only 4 pounds flying that well in the heavy wind (gusty swirly stuff). Looks like your plane is bigger than my Laser3D at 6 pounds.
