I have a request from one of you on my Berkik 3 flying wing video comment, it says to try adding landing gear on it, so this video is an answer to it, but instead using Berkik 3, I use B-2 Spirit model. This RC model plane also inspired by latest Freewing B-2 Spirit model and I enlarge it a bit to 2500mm. I always thought an RC B-2 Spirit is just an RC flying wing with landing gear, maybe just like a walking in the park, easy. I choose twin EDF setup for the powerplant, I use 70mm 6 blades 4S EDF. I test them on test bench, and each of them can reach about 1200-1500 gram of thrust (without thrust tube) with 80A ESC. But it turned out far from it, just like my Mirage and F-35, 70mm 6 blades 4S disappointed me once again. I have 70mm 6S 12 blades EDF but only one unit. So I swap them with pusher props configuration. I use twin DXW 3536 1200kv brushless motor for pusher prop setup, with 50A ESC and 4S battery (2200mAh), using 9 inch 3 blades propeller. Pusher props give enough power but still she couldn't take off from the ground, I suspect the front landing gear is not high enough to give the plane slightly higher AoA. This model is the heaviest model I ever build and fly, it's 3000 gram, yes it's finally fly by hand launch. The weight before adding ballast is 2500 gram and I had difficulty on finding things to be use for ballast, but I got the idea from real gliders, they use water as ballast on each wing. So I fill 2 bags of water each weigh 250 gram, and place them on the nose to balance on the CG. I copy the CG location from Freewing's model and resize it according to my model scale. I also use drag rudder, the plane is very stable, easy to control and floating in the air. I'm not sure it's stable because of main the landing gear doors that always open or because of the drag rudder, I think the model is a success for me even though doesn't use EDF and can't take off from wheels, but until this video is uploaded I already in the process swapping landing gears with retract landing gear that use bigger proper wheels and higher.

I will make Icon A5 seaplane for the next RC model. This is how I model the 3D model on Blender, sorry for low resolution, I forgot to setup the recording quality to high. I will use 5mm foam board for this model. Learning from the failed take off of my CL-415 on water, this time I will not make a scale hull for seaplane, I will use flat bottomed hull. I also will use clear canopy so I can use it as an FPV plane too, with camera inside the cockpit. I will start building tomorrow.

Announcement for our new channel Babyplane. Babyplane channel will be dedicating on fatty, egg plane, baby plane kind of RC model plane, no scale model, just cute models. This F4U Corsair is for a start. You can visit the build video in our channel here https://youtu.be/gvEmzMnw6as

This is my first time making this kind of video. I usually only upload the complete build video of any model that I build, but this time I want to share with you the process before building and flying the RC model. The model is Bayraktar TB2 UAV, it's a Turkish military UAV that also use by Ukrainian Navy to fight against Russian invasion. The shape is unique and it's a beautiful unmanned plane. The model wingspan is 2 meter or 2000 mm or 78.7 inches. I will use 5 servo, 4 x 9 gram for ailerons and Vtail and a single 360 degree servo for rotating the camera dome. The front landing gear will use retract like the real plane, and main landing gear with 3mm thick aluminum strip. The material is mainly 5mm foam and some 2mm plywood for formers and also 7mm carbon fiber tube for wing joiner and tail booms. I also have an announcement on this video, that design tutorial part 2 will be released exclusive to members of my channel. If you want to see the upcoming part 2 you have to Join Membership, choose Master Membership for that.

This video is a continuation from previous video which is about how to design RC plane plans. When designing RC plane plans, we need to build and test it to fly so we can improve the plans. I made this model using Blender 3D program, Pepakura Designer and together with Inkscape. You can find part 1 of how to use it on my channel. This Zenith CH750 model is modelled exactly the same with the real one but it's smaller, the wingspan is 120cm or 47.2 inches. I usually modified, or enlarge the size of the wing and stabilizer when converting it to RC model, but this time I make it exactly scale for education purpose. The model finally can fly after some trial, but with some adjustment from the real one.

As my promise when I reached 50K subscriber I will make a tutorial on how to design, so here it is guys, part one of them. The tutorial will divided into 2 parts, first will cover about basic modelling and how I model from 3 view drawing and photo to 3D model, this episode is for you that still learning on 3D modelling. Part 2 will cover about how to convert 3D model into printable plans than are ready for use to build our RC plane. I will use 2 softwares : Blender for 3D modelling and Inkscape for prepare the 3 view drawing The model I choose is Zenith CH750 Super Duty, I hope it will not hard to model and build. After releasing this video I will start building it, so after this I will make a video of building and flying the RC plane that I model here. This is my first software tutorial I hope this video can be useful to you Join this channel to get access to perks: https://www.youtube.com/channel/UC64lnLfKm09f13iayaCOX0A/join

I've plan to build life size RC WALL-E from 5 years ago (2016), but never happen until now. This build needs about a month to finish, the main material is, actually it made out of 50:50 depron foam and plywood, also using EVA foam on some parts. This RC Robot right arm can move or rotate up and down, can also twist and has a robot gripper hand, so he can be use to pick up trash, while the left arm unusable just glued to his body. There's a ramp door on the front that can be open and close with RC to deposit the trash. Maintenance door is on the back. I also made a simple lunch box for him. After it finish, it looks cute but surprisingly big, maybe a bit bigger than the real size, maybe about 105-110 %. I have problem on his track, the track is made out of plywood and EVA foam and that's where the problem begin. Because the soft EVA foam it has more grip thus makes the robot very hard to turn on rough ground like concrete or asphalt, but it has no problem turning or pivoting on smooth surface like ceramic tiles. Because I'm running out of time, I missed adding the sound system, my plan is just using portable speaker and mp3 player for the sound, or just by using Bluetooth speaker.

As per request this is onboard cam video on MQ-9 Reaper looks like. It's not much just an ordinary onboard cam footage, but it's quite smooth ride without any visible vibration. It's not FPV just recorded video. The camera angle is perfect, I can still view the ground and the front while still frame the rear view with all landing gear and ordnance details like bombs and missiles. I flew this "UAV drone" 2 times and all flights were successfully recorded from take off to landing. Both take offs and landings were flawless, I like this model.

The plan is to make a simple model to finish on the end of November or in beginning of December. I choose this flying wing because it's easy to build and it flies great. Last weekend I couldn't fly my scale planes because of windy season, so I think flying wing will do fine on windy condition. Also I want to fly it with FPV setup because I haven't fly with FPV for quite long time since my Sky Arrow crashed. Actually I want to just release the plans for Berkik 2, but the files is on my old PC hard drive, so I remodeled it in Blender. I change some of the segment joints, make it bigger from 1200mm to 1300mm because I will build it with 6mm depron/ foam instead of 3mm, which is originally Berkik 2 material. Some people accused me for copying someone else's design when I post the photo of Berkik 3 on Facebook. That's not true, if you look closely it's a different beast. Berkik 3 (2021) is a modified version of Berkik 2 (2016) and developed from Berkik 1 (2014) you can search it on Youtube and see my old videos. My Berkik flying wing was not inspired by any commercial or homemade flying wing designs, it was evolved from the first version which is inspired by Boeing X48B Blended Wing Body design. Oh I almost forgot and I didn't mention it on the video, Berkik is a type of bird, forest snipe or Chinese snipe. And one more thing, I will report the progress for Boeing 747 project in the end of each episode like this. Thank you and enjoy the plans.

The first 1,000 people to use this link will get a 1 month free trial of Skillshare: https://skl.sh/juliusperdanapaperreplikarcprojects10211 The CG or Center of Gravity is the most important thing for RC model flight, because without setting up the CG correctly, your plane will have bigger chance to crash on the first flight. When Aircraft is flying it's hanging on its wing or surf on top of the wings so the CG is usually located on the wing but not always. For tradional configuration like plane with wing and stabilizer, the CG is always on the wing. Except the plane with canard the CG maybe located off the wing. CG is a center where the plane balanced when flying, not on ground but when flying. CG in aviation is actually quite complicated, but for model aircraft it's quite simple. There are 5 Ways to find RC plane CG. I compiled them from the easiest to the hardest : 1. By using your eye and finger 2. Sticks and thread 3. Drawing lines 4. Online CG calculator 5.

All the airframe part is complete, all I need to do is installing all the electronics. Because the flying weight will way off my target from 7,5 kg to 10 kg I will need to use more powerful battery from 3S to 4S. I also need to repair the main landing gear to make it more rigid on the fuselage construction. The airframe itself is 8 kg, I will use 4x DXW 3536 1200kv. When this video is release the plans is not ready yet so I still need to preparing it, maybe it will ready in a week. I will post it on community tab on my channel when the final plans is ready.

About 2 months ago I made a poll about what the next radio control plane model on my Youtube Channel Community tab. The winner is the P-47 Thunderbolt 'Razorback' version. I made the model in Blender 3D, you can see the process of 3D modelling in this video. The reason I made 1200mm wingspan is to match my P-51 Mustang scale, both have 1/10 scale. It equipped with servoless retractable landing gear. I have a problem locking the landing gear strut, I just use CA glue so it don't have enough strength. I also made the plans for fixed landing gear. At first I use the wrong CG which is 7,7 cm, the correct CG after some trial is exactly 7 cm from leading edge of the wing root. The can fly straight with the correct CG but needs more power, I recommend to use 4S for maximum performance, but you can still fly with 3S for scale flying. I haven't fly any RC model on the last months so I was a bit clumsy in landing and take off.

The first 1,000 people to use this link will get a 1 month free trial of Skillshare: https://skl.sh/juliusperdanapaperreplikarcprojects08211 I'm trying something new again this time, trying to build an RC car that I never do it before. I know the hardest RC model to make is model car, but it turned out to be a lot harder than I expected. There were many troubles on the process like, I had to change the gear ratio combination because the first one was too heavy for the motor. The second gear combination was okay but still not efficient. The first motor (1200kv) was burned out, I had to replace it with 650kv. The second gear combination broke their teeth and then I replace the material from PVC foamboard to 2mm plywood, each gear comprise of 4 sheets bonded together. The mechanism was to noisy until I applied lubrication to the gears. And then the steering servo broke I had to replace it with a new one. It's so frustrated I kicked the car few times in madness lol, but luckly it still has it shape. Beautiful shape actually, the back side I think I nailed it, but the front side not so much, because the front tip is supposed to be lower but the front wheel are on the way. After many troubles, finally on the last day it can run and I can RC-drive it as you can see on the video and it turned out quite a good sight. I learned so much on this project that I can use that experience for other future projects like, making gears, use 2 switches to reverse brushless rotation.

This time I'm trying something new, making an RC superyacht with depron or foamboard. This yacht model is quite big, about 160 cm or 63 inches length and 11 inches width. Because it made out of foam material, it needs about 3 kg ballast weight to fill the water ballast tanks. At first I was trying to utilize 2 broken servo as its power plant, but abandoned because one of the motor have lower speed than the other. I ended up using inrunner brushless motor with 50A boat ESC. I only use 9 gram plastic servo to drive the rudder. This model really came to life after adding interior details and LED lights. Why I'm using foam board, because I'm a lazy person, I imagine how hard and long hours to cut that plywood, sand it, add putty and sand it again, thanks, maybe next time. If you like this project maybe I will build again another yacht but with 3D printer.

I slow down a bit on this episode, I just want to share how to build the 4 dummy engines. Yes it's dummy engines, because I will use 4 pusher props. All 4 brushless motors will be placed on trailing edge on the inner segment of the wing. Why I don't use EDF, because it will be more expensive and also more heavy. I have lost a weight battle again, as I said on previous episode that I predicted the weight will be 5-6 kg, I think it will heavier, more like 7kg plus. But still can fly, I hope so. Beside dummy engines I also succeed making locking system for joining the 2 tail sections, and just need to repeat in all other segments.
