As we know, the AP planes we deal with will only allow certain (relatively small) diameters to be used because they get in the way of either the camera lens or in the pusher config they hit the rear fuse. This means we are fixed at higher rpms/pitch speeds to get the thrust.
With this project I hope can solve two things. Great tractor pulling thrust at low RPM and the ability to take without question any SLR or video camera I choose and fly/land at an extremely slow speed.
The plane is built around the new AXI (of course) 2820-14 swinging a 14-7 prop It is a brute. The rear fuse consists of two 3/8 x 48" carbon tubes glued together.
This allows the tubes to be oriented in the main fuse socket with the aid of a ply servo carrier structure. It is held in by a single carbon pin.
The main fuse is 2" beaded foam with 3 mm Depron sheeting. Once again It has ply in areas that need strength.
The fuse is incredibly stiff/strong as the 2" does not have any cutouts and once sheeted with the Depron it is very sound.
