Build Status:

4/3/19 – Was able to get about 8 packs through the quad. The maiden flight near perfect, flew great. I have to get some clean blackbox logs hopefully tomorrow and go through those. Motors came down pretty cool, felt pretty tight. I noticed a little yaw movement so I have to dig into that. Quick flight below from the DVR. Hoping I’ll have some time to get the latest RC of betaflight 4 on there along with the newest BLHeli_32 that was released only a day or so ago tonight / tomorrow. This was my first time flying a 6S and the lack of sag was really noticeable after 2 min of flight.

3/30/19 -Finished up wiring the motors to the ESC, FC to the ESC, and the power lead. Its pretty much finished at this point just waiting on the TBS Unify nano pro32 to arrive tomorrow. I’m planning on giving it a LOS test in the morning and to grab some blackbox logs.

I went with betaflight 4.0 (beta, its in RC4 now) and setup the newest RPM filter settings. This requires a 32-bit ESC and you mush flash the latest beta of BLHELI_32. What this enables is bi-directional dshot, which allow telemetry data to be sent over the signal line, which is the RPM information that is needed for the new filters. Anyways, for more info on RPM filters check out here:
https://github.com/betaflight/betaflight/wiki/Bidirectional-DSHOT-and-RPM-Filter

I went ahead and setup all my default settings, bind and updated crossfire, and followed the guide above along with some other resources to get the filters and settings where they need to be. I’ve setup the RPM filter on my freestyle quad last week and it was perfect. Cool motors, next to zero propwash before even touching the pids.

I’m curious to see how these filters work with a race focused quad, along with dealing with bent props.

3/28/19 – In progress. Currently testing out some 3D printed parts and modifying them for my needs. The Pyro32 ESC’s come with two pretty large caps, finding a spot to mount them was a little challenging. I also wanted to use crossfire and wasn’t to sure how I was going to mount the antenna. I found something that worked, just doing a few changed to the 3D model to add a bit more space to fit everything.

Notes
Apparently the iflight twing isn’t supported (yet) with the dual gyro and fusion logic by new betaflight 4.0 RPM filters. You have to set the board to a single gyro. More info here: https://github.com/betaflight/betaflight/issues/7886

You have to set gyro_to_use = FIRST

Betaflight Settings
ToDo: Set throttle limit to 95% – Allow 5% for BF corrections, black box, VTX.
