Whilst waiting for parts to arrive for the completion of the Viggen, my first Flitetest project, I decided to do a Nutball from a spare sheet of foam and a scrap motor.
It's a very easy plane to make, much simpler than the relatively complex Viggen, so didn't take long to make at all.
However, I didn't like the front-mounted motor or externally attached battery, which I thought looked ugly, so I mounted the motor internally and made access to the power pod through the top of the plane.
The result was a much neater-looking plane however required a much bigger battery (a 1300 3S) in order to compensate for the relocated motor.
With a big wing area I didn't think this would be a problem, however it turned what should be a slow floater into an absolute handful of a plane. Additionally, the elevator/rudder setup seemed highly ineffective with the Nutball not wanting to turn much at all. In fact, overall, flying the Nutball it recalled my first flights with the nose-heavy Radjet.
By the end of the second flight, which ended with the Nutball spiralling into the paddock, I'd decided to reduce weight with a smaller battery mounted on top, and to change to elevon mix layout to improve flight response...
