Matte red twin-boom twin-prop 3D printed RC plane

The detail that caught me off guard is how settled this thing already looks on the ground. A twin-fuselage, twin-boom aircraft with a prop and spinner on each pod, rolling out and turning a clean semi-circle on asphalt in a uniform matte red finish, and it appears to be 3D printed throughout. For a first look at a layout this unusual, that taxi says a lot.



The way it came together is just as interesting. The maker draws the planes in Fusion360, which is free for hobbyists, and uses no AI for the models, only for asking about technical aerodynamic questions. The power setup pairs two motors of the same type with two matching ESCs, and reverse-rotation propellers were delivered for the twin arrangement. The wings carry no anhedral, just a bit of droop, and the whole plane sits on multi-wheeled landing gear with black wheels. My own take: keeping both power halves identical seems like the sensible path for a first flight on a design like this.



There is one open item before the sky gets a turn. One motor spins more readily than the other, and the reason is still unresolved. The maker had not calibrated the ESCs yet and will do that, then take RPM measurements before flight, making sure both ESCs run the same settings. One possibility raised is that the brake or freewheeling settings differ between the two units. Until that is sorted, the build is considered ready to send, pending the motor issue. I would rather see that chased down now than discover it at full throttle.


Going with identical motors and ESCs on both pods looks like the smart move to me, and adding reverse-rotation props on top of that keeps the torque sides symmetric from the start. The trade-off is that any small mismatch between the two ESCs now stands out sharply, which is exactly what the uneven free-spin seems to show.

When the ESC calibration happens, is the plan to do each unit separately on the bench, or calibrate both at once from the same receiver channel? I am curious whether the RPM readings will be taken per motor afterward, since that would show straight away if the settings now match between the two pods.

If the flight goes well, I would suggest mixing a bit of differential thrust into the rudder at low throttle. With a propeller on each pod there is a real lever to work with, and it could make taxi steering and slow-speed handling sharper than rudder alone. The maker has said trying it is on the wishlist once piloting improves, and I think the twin layout earns it.
