Motor No. 6 won't work with DShot on my [BeeRotor F3](http://beerotor.com/product/beerotorf3-aio-flight-controller-with-osd/) hexacopter. I thought these problems would disappear as #4020 got implemented. Or was it for F4 and F7 only? Here's what `dma` says:\r\n\r\n```\r\nDMA:\r\nDMA1 Channel 1: MOTOR 3\r\nDMA1 Channel 2: LED_STRIP\r\nDMA1 Channel 3: MOTOR 1\r\nDMA1 Channel 4: MOTOR 4\r\nDMA1 Channel 5: MOTOR 5\r\nDMA1 Channel 6: FREE\r\nDMA1 Channel 7: MOTOR 2\r\nDMA2 Channel 1: ADC\r\nDMA2 Channel 2: FREE\r\nDMA2 Channel 3: FREE\r\nDMA2 Channel 4: FREE\r\nDMA2 Channel 5: FREE\r\n```\r\n\r\nIndeed, motor No. 6 is not there. (But the motor runs fine under analog ESC protocols and BLHeli_32 can talk to  / flash that ESC.)\r\n\r\nFor BeeRotor F4 (not F3), [there's a know issue](https://github.com/betaflight/betaflight/wiki/dshot-esc-protocol#beerotor-f4----for-use-with-a-hexacopter-motor-6-needs-to-be-moved-to-the-led-pin-on-the-sc-connector) that requires one to remap motor No. 6 to the LED pin and disable LEDs.\r\n\r\nHowever, I've just refurbished my hexacopter and added lots of fancy LEDs. So even if that^^^ same recipe worked for BeeRotor F3, it wouldn't be an option for me. :disappointed: Are there any other ways to get DShot working? Are the DMAR timers available on an F3?"},"comment":{"url":"https://api.github.com/repos/betaflight/betaflight/issues/comments/398983792","html_url":"https://github.com/betaflight/betaflight/issues/6137#issuecomment-398983792","issue_url":"https://api.github.com/repos/betaflight/betaflight/issues/6137","id":398983792,"node_id":"MDEyOklzc3VlQ29tbWVudDM5ODk4Mzc5Mg==","user":{"login":"andrejpodzimek","id":947737,"node_id":"MDQ6VXNlcjk0NzczNw==","avatar_url":"https://avatars0.githubusercontent.com/u/947737?v=4","gravatar_id":"","url":"https://api.github.com/users/andrejpodzimek","html_url":"https://github.com/andrejpodzimek","followers_url":"https://api.github.com/users/andrejpodzimek/followers","following_url":"https://api.github.com/users/andrejpodzimek/following{/other_user}","gists_url":"https://api.github.com/users/andrejpodzimek/gists{/gist_id}","starred_url":"https://api.github.com/users/andrejpodzimek/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/andrejpodzimek/subscriptions","organizations_url":"https://api.github.com/users/andrejpodzimek/orgs","repos_url":"https://api.github.com/users/andrejpodzimek/repos","events_url":"https://api.github.com/users/andrejpodzimek/events{/privacy}","received_events_url":"https://api.github.com/users/andrejpodzimek/received_events","type":"User","site_admin":false},"created_at":"2018-06-21T05:48:26Z","updated_at":"2018-06-21T05:48:26Z","author_association":"NONE","body":"BTW, I switched to Proshot1000, out of curiosity, and something weird happened: Only 2 motors worked, 3 and 4. They idled quite normally. The other motors didn’t start at all. DShot600 works just fine and all motors spin. (DShot1200 also works, but I’m not sure whether it’s safe to use it on an F3.) So it looks like there’s also an issue with Proshot."}}
