This time I'm back to basic by using all foam board material with some plywood parts. This De Havilland Tiger Moth biplane RC plane is designed to have the same scale as PT-17 Stearman. While Stearman wingspan is 1300mm this Tigermoth wingspan is 1200mm. Smaller but still can do short take off. Using 3536 1200kv brushless motor, 40A Esc and 3S 2200mah can give this plane more than 5 minutes of flight time. The flying weight is about 1145 gram, with that made this model has 4 on wing cube loading and that's almost like a glider. Because it's the same scale as Stearman you can use Stearman's papermodel pilot figure.

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 . You can search "HappyCow FX815 Speed Boat" on Google, you'll find it, 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. You can download the plans here : https://paper-replika.com/index.php/rc-foam-project/micro-rc-twin-otter-650mm People 3D print files are from Thingiverse.com - search figure, I found 6 decent figure models there, maybe even more because I stop searching after downloaded 6 models Join this channel to get access to perks: https://www.youtube.com/channel/UC64lnLfKm09f13iayaCOX0A/join Specs : 1.

This is the biggest RC model plane that I ever build and fly. The wingspan is 3000mm or almost 10ft. Use almost entirely 5mm foam board as the build material. In this video also the first time I made propeller spinners with 3D printer, and make foam wheels and firewall with laser cutter. I use Creality Ender-3 V2 Neo for 3D printer and 10W CR-Laser Module to convert Ender Printer into laser engraver and cutter. Those tools help me alot and I got best results. I also 3D print some of detail parts, I will share all the STLs along with the plans and decal when they are ready, please wait about a week for the files to be ready, but I hope it will be sooner.

This is how I model the 3D model before making plans to build RC model plane with foam board. I use Blender to model the 3D model. You can see more detail and in normal speed video when you become a Master member, there will be 2 parts, making outer shape and inner constructions.

This RC model is big but fly like a trainer, the wingspan of this Sukhoi Su-30 is 1060 mm or about 41.7 inch with the weight of 1200 gram or 2.6 lbs. Su-30 is very similar in shape with Su-27 and also Su-35, so with this plans you can make all of them. This a second design of the plane type, but this new model is different from the old one, this is bigger and also easier to build. I just use elevon for control surfaces and only 2 servos needed. The motor is also pretty small, I use Racestar 2212 1400kv brushless motor with 9 inch prop and 50A ESC, with that spec you can use 40A ESC with 3S 2200mah Lipo battery. The control is very easy, very tight turn radius. I think this model can also be equipped with 2x 64mm or 70mm EDF.

Hey guys, in this video, I'm sharing my journey of building a German U-boat RC model for recreating the final battle scene from the Greyhound movie. I already have the Catalina model, and now I'm building the U-boat RC model from scratch. I don't have any prior knowledge or experience of building an RC submarine, but I'm using my basic understanding of how submarines work. To start with, I created a 3D model of the U-boat type VII with a length of 182 cm or about 71.8 inches using Blender. For the material, I decided to use PVC foamboard instead of foam board, as it is sturdier and easier to cut, shape, and assemble using my model making technique. While I won't be making a scale model, I aim to create a rough shape of the U-boat. In this video, I won't be explaining how I built the model, but I will be showcasing its features. Just like a real submarine, it uses water ballast tanks with two pumps for filling and draining the tank, two servos (three if it uses a torpedo), a brushless motor, and ESC. Before adding the final details and paint, I need to ensure that it works. It should be able to float and submerge under water, but not too deep - just at periscope depth. In my next video, I will go over the details of how I built this RC submarine for those interested in the process of DIY RC submarine building.

This model is capable of take off and landing on water, by detaching all the landing gear, patch the landing gear well and cover it again using packing tapes. I need to coat the hull or the underbelly with 4 layers of plastic primer, even before doing that I also already coating the hull with 2 layer of clear varnish to make it water tight. Even with that effort it still a bit leaking if it takes too long on water before taking off. I suspect the leaking is from the main landing gear well on each sides. Also I need to replace both floats with foam block to prevent leaking.

Finally my scratchbuilt PBY Catalina RC plane can fly normally with just a few setup.

I thought this was going to be an easy maiden flight, but I was totally wrong. The RC plane is PBY Catalina with 90 inch wingspan, with 6,2 pounds weight. It made out of 5mm Depron foam and 3mm plywood formers. There's still some part of the plane that needed to be fixed so it can fly normally, but I'm very optimistic that it can fly nicely next week on the next flight test again.

I'm not sure what happened, but everything happened so quickly. I suspect that the EDF didn't have enough down thrust angle, which caused the plane to have a constant pitch down tendency when powered up. I also have to take some responsibility as the pilot. I wasn't fast enough to anticipate the pitch down moment. Typically, when my plane takes off, I ease the elevator and increase throttle to achieve a scale takeoff attitude. However, during this accident, when I increased power, the plane pitched down unexpectedly, and I was caught off guard and unable to respond in time. Fortunately, the wing is still intact, and the fuselage is repairable. I'll try it again next time, taking into account what I learned from this experience.

The idea is to have an experience as if we on board a real houseboat and sailing away on the lake. The interior was made to look as real as possible to give convincing experience. The scale of the model is 1/10 scale. I also build a special camera robot to navigate inside the houseboat interior. We use 2 transmitters for the houseboat model and a camera bot. The camera bot also equipped with video transmitter for navigating inside the houseboat. Join this channel to get access to perks: https://www.youtube.com/channel/UC64lnLfKm09f13iayaCOX0A/join

This is a small project, just to wait until parts for the next project arrived. The wingspan is 800mm the flying weight is 70 gram. I use the electronic from 2 channel toy RC plane, it has differential thrust to turn and throttle management for ascending and descending. The material is 10mm EPS foam or styrofoam. It needs weight ballast to balance on the CG, the weight of battery alone couldn't balance it. The CG is about 13 cm from the front tip. I need to put fixed control surfaces, just so I can angled them as reflex. The angle of the reflex is about 30 degree. This plane needs proper adjustment on throttle to fly straight, it can fly level at maximum 75% throttle on fully charged battery, and adjust it on the flight as needed.

It's already windy season here, I need a small model jet for flying into the wind. Actually I'm already starting building the A-10 Warthog model but venture a bit building park jet model, don't worry I will continue building the Warthog again. I choose Dassault Rafale because requests from you and also our air force (Indonesia) will also have this French fighter jet in the future. I choose B model because I think it looks cooler. After it finish I realize that this model is hard to hold with one hand, and that's gave me an idea to build the catapult launcher too. I shared the plans on the links below.

This Cartoon A6M Zero RC plane is a continuation of cartoon rc plane series after F4U Corsair. Unlike the Corsair model I will not post the build video on Babyplane channel anymore, from now on I will put future cartoon models on Julius Perdana channel. The cartoon series is a collaboration between my friend Hendi Susanto and me, I design the plans and he build the model for more frequent updates, hopefully. I also plan to make another series, that is park RC jet models that is not too big and easy to build in the future, while still making build video of my own build. I learned After Effects in just 3 days by watching Youtube tutorial videos, just to make a clip of the "dogfight" video clip between my cats here. Disclaimer : all scenes are fake, generated in CGI. Because in my country and maybe around the world, it's forbidden to fly RC plane on residencial area.

This is my second attempt building a big DIY RC car, the first one was a Datsun 240z model. This time I choose Ghostbusters Ecto 1, because I think it will suit the season. The dimension of this RC Ecto-1 is about 146 cm or 57.4 inch.

All start with making micro/ mini RC plane, I made a huge RC aircraft carrier so I can launch the plane and try landing on top of it while the carrier is sailing on the water. The aircraft carrier model length is 4 meters, all made out of 6mm depron foam or polyfoam or foam board. My original plan for making this video is just for entertainment not focusing on tutorial, so I only prepare the plane plans, not the ship. The aircraft carrier plans is very rough and needs builder improvisation instead of sticking to the plans, because the plans is only in rough shape. But I will consider sharing it too if this video reached 200K view.
