DHC-2 Beaver RC Plane with 3D Printed Parts and Foamboard plans

This DIY Beaver model RC plane was built solely as a test bed for a brushless motor, esc and prop that sponsored by T-motor. This model is also an experiment to build an RC plane using 2 different materials together, which are 3D printed parts and depron foam or foam board. I am still learning to make 3D model parts for RC model plane and the result is far from what I aimed to be. It's just basically 3D printing parts without any optimization for flying model. I finally found out that Blender is not a good choice to make 3D model for 3D printed flying model, so the result is jaggy and not smooth enough and also not optimized. And with so many parts to be printed and each with unique setup, make it more complicated, no wonder they sell the 3D printed kits so expensive, because there are so much work to do to prepare it. Nevertheless the result is stunning, despite not so good quality build but the end product is so beautiful in the air and on land.

F/A-18F Super Hornet 1000mm RC Plane

Yet another Fighter jet, this time is F/A-18F the 2 seated Super Hornet, the wingspan is about 1 meter plus, with the flying weight about 1700 gram. It's still using the same EDF as my previous jet, which is 70mm 12 blades FMS EDF. I use 6S battery by connecting two 3S 2200mAh Lipo batteries in series. Because F-18 has dual exhaust I have to make a bifurcated duct made form art card, the power is not too different from if without using split duct exhaust. I was planning to copy the CG from the FMS Super Hornet but when I examine it the FMS Super Hornet was not made in scale with the real plane, the shape of the wing is different from the real plane, maybe they use F-18 legacy hornet as a base and just modify the LERX and the air intake. So I have to calculate it manually.

There's a technical problem on the background about making F-18 Super Hornet video that made the video will not ready yet on time for this month. So I specifically made this micro RC Twin Otter as a filler also because my friend Ben keep asking the plans (lol). This model is very easy to make using styrofoam for the fuselage and 3mm depron or foam board for the wing and stabilizers. I use low density styrofoam for light weight flying model. Styrofoam is basically an EPS foam or Expanded Polystyrene, maybe the styro name comes from styrene. EPS foam also known as Thermo cool/ col foam. The wingspan on the model is 65 cm or about 25.5 inch, with the flying weight using 1 cell 300mAh lipo about 70 gram. I also incorporated 3D printed parts on this model for making, nose cone, landing gear strut fairing and wheels. For you that don't have a 3D printer you can use the plans to make DIY parts with foam. I use electronics from Air-815 a cheap toy plane, the price maybe about $7. It has 2 channels, flying control only using differential thrust, so there's no elevator, to move up and down you have to control the throttle. It's quite stable because there's a built in gyro.
Sukhoi Su-57 Felon RC Plane Plans

I made this Sukhoi because I already made an F-22 Raptor plans, because I think it would be interesting if I made its rival too which is Sukhoi Su-57 Felon or in Russia known as T-50 PAK FA. This model is not design specifically for neither EDF or pusher prop, I just design the model airfame that can be built with 5-6mm foam board or depron or polyfoam, without any propulsion mounting design. You have to figure out yourself, but you can see on the build video how I install a single 70mm EDF on center between the two exhaust. For this setup I use FMS 12 blades 6S 70mm EDF, with 2.6 kg thrust with 80A ESC and 6S 2200mAh Lipo, I think it's more than enough than the weight itself. I also convert it from EDF to pusher prop using DXW 3536 1200kv brushless motor, 10 inch prop, 50A ESC and 3S 2200 mAh Lipo. Both perform well, while there's some problem in the beginning, you can see it on the build video on Youtube.
