I received the Tsubasa kit, created and manufactured by Jerem Aero, on Friday. It’s a small flying wing with an awesome look. It arrived in a custom-made box built from thick honeycomb-style cardboard.
The kit contains a single-piece wing, a small exposed carbon canopy, an exposed carbon vertical fin that plugs into the sleeve at the rear of the fuselage, two 3D-printed carbon aileron horns, and two stickers to close the servo hatches.
The molding quality is excellent and the paintwork is superb, along with a really striking color scheme.
My version is the Strong version. In fact, it’s the very first one of this version that Jérémy has produced. He was expecting an empty weight of around 290 g, but the wing came out at only 256 g, which is just 10 g more than the standard version. This will make this Tsubasa Strong even more versatile.
Let’s take a closer look at the construction details. The servo bays are machined, and the upper wing skin has received an additional layer of carbon.
The spar has an opening to allow the servo wires to pass through. There are false ribs on each side of the servo bay to reinforce the wing against torsion. The servo bays don’t have a lip yet, but this will be added on future kits.
The ailerons are hinged on the underside, in an F3F style, and there is no sealing lip. A bit of tape will do the job.
The vertical fin slides onto the fuselage. I’m still hesitating about how to secure it. A pin could do the job, but I’m thinking more about using a small alignment key for positioning, and then simply securing it with tape.
For the servos, I’m going with MKS HV6100 servos with Servorahmen frames. However, I’ll use standard servo arms with aluminum clevises from Tomas Liu Studio, along with a 2.5 mm diameter carbon rod.
Later on, I’m thinking about installing a small ballast tube.
Alright, enough talking—time to start the build, which shouldn’t take long. Stay tuned!
