There’s a new SirinFPV on the block ( revision G) and I got a chance to try it out! I have been told there are only a few changes ( MPU6000 vs 6500 and Onboard 3.3v) but those are very significant to me! The MPU6000 from what I hear is a better gyro, runs 8khz SPI and does not have the jitter problem the 6500 has. The 3.3v while it may seem small helped out my build a lot. With the Owl camera it has a little voltage regulator it comes with which converts 5-24v down to 3.3v for the camera… I can finally scrap that and wire it in directly.
Anyone else hate their Fatshark batteries? I have two of the newer style ones and they both are horrible. Really high internal resistance, IR, from the start. So I finally got around to creating an 18650 version of the fatshark battery mods. Why 18650? While they are Lithium Ion they are listed at a 4.2 max. They are readily available. They are cheap. What more could you ask for? In a slightly bigger package I am cramming 3400mah versus 1800mah… and a better IR.
So let’s get started, what do you need?
- 2x 18650 cells (I used Panasonic NCR18650B)
- 1x 2.1mm Barrel Plug
- 1x Balance Plug JST-XH**
- 3x Balance Terminals**
- 3x colored 26 awg wire
- 1x 2S Battery Balance LED
** When you buy from DigiKey I suggest ordering more. I also suggest ordering some 2S, 3S, 4S and higher plugs so that you save on shipping.
Whew, just completed another new build. I continued with another 130 sized build to keep a couple of the smaller quads in the fleet. I actually tore apart an older Airblade Assault to build this one. I really liked the Owl camera from RunCam for a small 130 build as it extends the flying ability into the night! It’s not the best for day flying, but I think it is better than many of the smaller pico/micro sized cameras (although larger and heavier). This build did add a few new elements I have not tried before (SirinFPV Flight Controller, FVT LittleBee Pro 4-in-1 ESC, and the AirBladeX 130) below I go into each of them in a little bit more detail!.
SirinFPV Flight Controller
This is going to quickly become the go-to for flight controllers! This flight controller features a STM32F3 processor, a integrated OSD, Blackbox SD Card port, and an integrated video transmitter. It runs Betaflight and will soon be in the upcoming builds by default. It uses VCP so you still have access to all UART ports without interference with USB. Since Betaflight 2.6.1 and up you can run ESC pass-through on VCP! The OSD is pretty minimal, but that’s what you want in a racing quad. The SirinFPV features the MPU6500 gyro/accel and is connected via SPI so it supports 8khz\8khz mode! It has the capability to run 6 motors aswell. The OSD and VTX are accessible via CLI, and the VTX can change the channels via OSD. It does require a 5v 1amp power supply!
It’s available for pre-order now!
