This Framework was Motivated by the FireFlo V2 and the Alpine Drones Micro H. My goals were to keep it give protection for gear that is onboard and crash resistant, light weight.
~ 105mm is measured by it. The V1 frame weighs the frame and 10g weighs ~ 8g when published in PLA. My full build (now V2 base and V1 top) weighs ~38g with no battery. It's designed around 8.5mm motors as well as the Micro Scisky flight controller. The camera mount is angled 13 levels up to accommodate flight.
Guide to configuring the Micro Scisky
See the full build instructions on instructables.
- Flight Controller: MicroScisky
- Motors: Hubsan X4 H107c 8.5mm Motors
- Battery: I use a mixture of a few batteries. 380mAh Hubsan, 500mAh Hubsan and 300mAh Nano-Techs CAUTION: When using the Nano-Techs, be sure that the battery polarity is correct. I have had to switch the connector position.
- Props: I'm currently using Ladybird props. They hold up a lot better than the Hubsan props.
- Battery Pigtail: I cut among the leads from a charging adapter.
- Nylon Hardware: M3 nylon nuts and machine screws. I used the machine screws and cut them to size after attaching to the frame.
- Printable Standoff And Clip: As opposed to using nylon hardware, navyblueboss made a very nice pin and clip set. I haven't yet published a set of these but they look great.
- JST SH Connector: A JST SH connector may be used to get get a 5v source for fpv equipment straight from the Scisky. CAUTION: I managed to fry the power source on one of my Scisky boards. When using the FC to electricity FPV gear other users have reported the same. Another option is to use a voltage regulator or battery power out of battery for camera and VTX.
All in 1 FPV Gear
There are a few new options for an FPV setup. You can connect these power and do not need a voltage regulator. These camera and video transmitter modules can be used with the frame. Here are a few options that I have tested with.
DIY FPV Gear
These components will let you build the FPV setup yourself. These elements are for v1, v2, and v3 frames.
The Micro Scisky has a receiver. Below are some radios.
People have had success transplanting the flight controller and motors out of a Hubsan X4 H107C. Going this route, you would get a radio, flight controller, a battery, motors and a pair of props . You can then add FPV using VTX, a camera and a voltage regulator. I haven't tried this route yet, but intend to build a buddy one. Once I do I will post my results.
- 1/9/2016 - Added bottom-v2-experimental. I was able to reduce the weight of the bottom of the frame to ~5.5g. This conserves ~1.5gram from v1. I don't think the frame durability is going to be affected much.
- 1/10/2016 - Added top-v2-experimental. I was able to reduce the weight of the top of the frame to ~2.3g. This rescue ~0.5g from v1. When published in PLA bottom and the top combined should be ~ 8g. Both the top and bottom will feel a bit flexy but once they're connected the quad will feel solid but still allow some give in crashes. I recommend using M3 nylon hardware to secure the pieces together. I don't anticipate the v2 compromising durability at all. NOTE: I have printed, but not flown with this top. So that I will need to find some time to make the switch my camera is hot glued to the top that is v1.
- 1/11/2016 - Added top-v2-no-cam-experimental. Iwanted to see it preformed with no FPV gear and've been doing some indoor LOS flying. Wow, there is a good deal of pop.
- 1/16/2016 - Added top-v2-cam-down-7. This points the camera down 7 levels. So as to clear the base plate, I had to push the camera forward just a bit so the camera doesn't extend below the bottom plate, and I made 1mm taller's standoffs. I also removed the term "experimental" from v2 filenames.
- 5/9/2016 - Added bottom-v3. This version should be much more powerful than v2 but it weighs only ~0.2g more. I was able to increase the depth of the arms while saving some weight. I also added the back and some relief to make it easier to plug in a USB cable into the Scisky.
- 7/25/2016 - Added v4 top and bottom which allow for all in one FPV modules. The bottom has hooks for an battery and the top has a recessed seat for the FPV gear. I also added a version of the v4 underside. I didn't test the 7mm version as I don't have some motors that are 7mm. Please let me know if you use this frame, how it works.
Layer Height: 0.3mm
Bottom Piece: 4 Perimeters
Top Piece: 2 Perimeters
Extrusion Width: 0.4mm for all tops and v1, and v2 bottoms. 0.48mm for v3 and v4 bottoms. I optimized the measurements to be all perimeters hoping that it makes it more powerful.
