R/C Helicopter project


Here is another quick update. The battery tray is now modeled and in place. I also made some aesthetic changes to the tray above it. Screws have also been added.


I have now added a few servo motors and a swash plate guide at the top. The servos are rough models but with some detail including the output gear. Here are a few screenshots.


Here are 4 more screen shots with progress. Now the motor mount is in its rough place. We have landing skid mounts as well with some frame spacers. Also added some rubber supports to the servos, just like if it were the real install.


And one more just to show the whole model up to now.

As mentioned before things may change as the model evolves. Modeling other parts may move the location of some of these parts. This is mostly because I am modeling it without any diagram, but using lots of images and parts as examples when I can.


Now we have the base plate to assist with frame stiffening as well as landing gear strength.


Here we now have the landing skids. Still lots to do, but making a good amount of progress.


Now we have the fan shroud for directing air flow over the head of the motor to help with cooling.

As with all previous parts, this is subject to change as the model evolves.


I have now modeled the clutch bell, clutch liner, magnets and bearing. The bearing is just outside dimensions for visual reference only.

NOTE: The threads were added with Fusion 360. Everything else was completed with Shapr3D.


As I was working on a couple more parts for that clutch bell I realized it was in the wrong location. It belongs above the fan shroud as the fan belongs there. So I assembled the new parts and updated the approximate location. Here are a few screen shots of it with the additional parts and it’s new location.


I modeled the starter coupler today. It’s a bit hard to see it in the assembly, so I have a couple screenshot of it out of the helicopter. Next will the bearing block assembly that holds it in place to the frames and gear.

NOTE: As with the parts before, I modeled the threads with Fusion 360. All other modeling has been with Shapr3D. The set screws were also modeled with Shapr3D and threads added via Fusion 360.


When complete it will be a model of a Remote Controlled Helicopter. I used to competition fly, so I have a huge interest in them. I no longer fly them, it’s been at least 6 years since I have flown one at all. But it will look something like the one below.

This is probably one of the best pictures I have of me flying one of my machines. I had over 72 of them over the course of 10 or so years. I still have 4 and two are pretty much ready to fly. This one is an all electric model that I was hovering up side down low to the ground for a photo.


I modeled the remaining bearing block for the clutch bell assembly and have it placed in the frame. Here are a few views with the frame split so you can see the inner components all together.


Fuel tank is now modeled and located in the frame. Have the tank hollowed out with the shell feature. Rubber mounts to prevent moving around and damaging the tank from vibrations. The top of the tank has a pressure inlet and the side of the tank has the feed for the motor. I still need to add the fuel tube adapter to allow a feed line to be connected.

I will now add servo motors for the throttle and tail rotor.


Here I have added the Throttle Servo as well as the Tail Rotor Servo. They are in their approximate locations and it is possible they could move as the model evolves.


Over the last two days I exported all parts and imported then into Fusion 360. I then aligned all parts and added colors that closely represent how this model may look if it were real. I then rendered them for only a short amount of time (10 minutes max) just to get some rough lifelike images.

Maybe once I fully align the parts properly I will spend the time for a high quality render. For now here are a couple images. I will also get a couple close up renders for the next post.

NOTE: 100% Designed with Shapr3D and rendered with Fusion 360.


Here are 4 close up renders, I let these ones run for about 25 minutes to bring the detail up some. The third image gives a good view of the motor mount, fuel tank and servo motor. The fuel tank is translucent and has a pink shade to it. The reason I went with the pink is the fuel is pink, so it almost looks as thought it has fuel in it.


Here we have a few small items modeled. I modeled the front and rear canopy mounting posts, there are some oval tabs that they mount too, the idea is in a crash the tabs would fold and break rather than break the frame.

Also modeled are the bluish/purple parts on each servo. These are mounting tabs so that the screws won’t pull through the rubber grommets/mounts.

As before, these parts are positioned where I believe they will go, this may change as the model evolves.


For anyone wondering, the fasteners are downloaded in step format from McMaster.com , and any mating parts that have threads, those parts were imported into Fusion 360, threads added, then exported back out and brought back into Shapr3D.

All modeling is done with Shapr3D. For the renderings I am using Fusion 360 on a Custom PC.

Here are the Specs of the custom built PC:

  • Corsair Graphite Series 780T
  • ASUS ROG Rampage VI Apex
  • Intel Core i9-7900X (OC’ed to 4.6 GHz) 10 Core (20 with Hyper Threading)
  • Corsair Hydro Series H115i Extreme Performance Liquid CPU Cooler
  • Corsair Vengeance LPX DDR 64GB
  • EVGA GeForce GTX 1080 Ti SC2 HYBRID, 11GB
  • EVGA GeForce GTX 1080 Ti SC2 11GB
  • 3 x 1TB Samsung 960 Pro NVMe M.2 SSD
  • 500GB Samsung 950 Pro NVMe M.2 SSD
  • Corsair HX1200 Watt PSU
  • Windows 10 Pro x64


I have now added the remaining screws that I left out. I have also model a small capture nut/plate that the servo screws tighten up to. These pieces have have a nub on them that catches a hole in the frame to assist with centering and tightening up the bolts.


Here we have the elevator controls modeled and installed in its approximate location. It has a max of 21 degrees of movement in both directions (up or down). Here are a few screen shots.

Note: As stated before, threads are modeled with Fusion 360, all other work is done with Shapr3D. The model may also change as it evolves.
