Came back from the field today with the Jupiter. The wind was not so permitting, about 15-16 mph, and the sky was cloudy. Visibility was not that great, but I was able to put in 2 flies. The plane tracked, but was shaken up at this windspeed.
I have to reinforce the landing block. It keeps on popping off. My field is badly rough with tractor's treads, cracked dirt. The landing block does not hold for very long, despite heavily epoxied. There is another thing I did not mentioned in the previous replies. You guys need to connect the rear wheel push rod to the LEFT arm of the servo. The diagram in the manual is INCORRECT, in which it connects to the right arm. If you follow the manual, what you find at the field is the plane will steer to the OPPOSITE direction of where you want it to go.
