I redesign this RC foam board P-51D Mustang from the original plans that I made for papermodel. I simplify the design for easier building. The main material is still 5mm depron or polyfoam foam board. In this project it's the first time I use 4 of these new techniques. They are DIY spinner, new clear canopy molding, laminating film for covering and DIY retractable landing gear. I'm quite satisfied with all the result, except the landing gear still needs more improvement but, it has lots of potential. Although it worked but still, I will improve it in future projects. This Mustang is fast, even with just 50% throttle, I was trying hard to not hit a tree when flying it. I should add flaps for slower landing, but the time for this project is limited so I'll leave it to you to improvise with this plans, good luck and have a good building time.

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 luckily 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'm back making not so large RC model again, this time around 1 meter wingspan. I already aimed for this T-6A Texan II US Air Force trainer plane to make an RC flying model of it for some time. I already know it will be a good flyer by looking of its slick fuselage and dihedral type low wing, and it is. The building process is also relatively easy and can be build in about a week. The main material is 5mm depron or polyfoam you can also use foamboard. The landing gear that comes with the plans is fixed type landing gear, but you can easily change it to retractable landing gear to give more scale looks. The model is already have scale looks like the real thing, but actually this model is a semi scale model, because I modify the wing larger and make all stabilizers more surface area. I like this model because of the scale look and how easy to control.

All the fuselage parts are already finish, although I haven't figured out about the locking system for connecting each segments. In the meantime I just using packing tape to join them together, I'll cover it on part 4. The total length of the complete fuselage is about 4.5 meter or about 14.7 ft and the weight so far about 3800 gram. Looks like I have lost the weight battle, the final result will be above 4000 gram, maybe with the wing and electronik it will be around 5000 - 6000 gram. But still it will be very light if we look to its wing loading.
