Re: Silent outrunner and ESC for less then $60 The Holmes esc's may have better startup because of the MCU he is using. @duke4you the firmware is not really specific to crawlers. The new ones I compile have adjusted settings that improve arming with surface radios. and sometimes the Dukes of Hazard sound. Older ones had to be compiled specifically for crawlers, but since 1.64 or so it is not specific. There can be some tweaking if you are planning on putting the esc in a micro crawler in the compiling. It also depends on where you get your firmware files from too. |
Re: Silent outrunner and ESC for less then $60 Very interesting to see performance like that from Chinese component! Does the ESC have a 5v out? planning on using a direct powered servo, but it would be great to power the receiver from the ESC, so I don't have to add a BEC |
Re: Silent outrunner and ESC for less then $60 It is close :ror:...and 4s ....yeay !! https://www.facebook.com/HolmesHobbi...84031281629881 https://scontent.fbcn7-2.fna.fbcdn.n...27&oe=60BB41E5 |

Re: Silent outrunner and ESC for less then $60 So what settings are you using with the blheli32 firmware? Anymore testing on this? I’m looking at using it with a Team Brood riot S 1850kv on 4s... maybe 6s if I can get the gearing right without buying a new motor... Lou |

Re: Silent outrunner and ESC for less then $60 Well, I have finally had to come ask for help! I have flashed an Iflight 55A with the Iflight_crawler_1.64-1800kv_FULL.BIN.bin from Voodoobrew. There have been a few hurdles along the way, but nothing major, just inconvenient, but now I am almost stuck. When powered up it plays the arming tone on repeat. The ESC connects to the ESC_Config_tool_1_68 and I have matched the throttle calibration to the readings from a Castle X and played with the trim, powered on the esc before the radio etc. Any suggestions to the simple thing that I am missing?? |

Order 2 new ST Links and managedto install the firmware (I hope:roll:). I will try to test the ESC against the MicroX onceI change the chassis of my mini comp crawler. |
Re: Silent outrunner and ESC for less then $60 The was an issue with some surface receivers (Spektrum are the ones that mainly have this issue) where they are not being recognized as being 1000us-2000us servo signal input during an automatic input calibration. I had found a way to widen the sensitivity of the servo detection when compiling my own firmware but it probably never made it to my google drive files unfortunately. The newer experimental 1.67 firmware seems to not have this issue if you can install that you should bee good. Here is a list of the experimental partial bins from Alka on GitHub https://github.com/AlkaMotors/AM32-M...mental/Release These need to be flashed to 0x08001000 If you are also running Spektrum receivers I had better luck powering on the older firmware with the transmitter off as the default safety output of the Spektrum receiver is 1500us. Once it arms you can turn the transmitter on. Also if you edited the eeprom using an Arduino or flight controller and the configuration tool then bidirectional and complementary need to be selected. I will receive messages faster if you send them to Voodoobrew in the AM32 slack chat https://join.slack.com/t/am32/shared...6Ga0CG6jlfFknA or you can ask in the support channel where there are a few people willing to help. I am on there daily, where I might forget to check in here for weeks some times. |
Re: Silent outrunner and ESC for less then $60 I added instructions on how to adjust the settings yourself using an Arduino. This also lets you update the firmware (not with installing the bootloader) using the receiver plug instead of having to use the ST-Link. Quote:

Re: Silent outrunner and ESC for less then $60 What esc’s are compatible with the arduino method? Lou |
Re: Silent outrunner and ESC for less then $60 |
Re: Silent outrunner and ESC for less then $60 You don’t “need” the breadboard using the Arduino, correct? With the two wire connection you describe, I can flash the firmware and adjust it? Lou |

Re: Silent outrunner and ESC for less then $60 Thanks Mr Brew! I will give that a go when they make it back onto the table. |
Re: Silent outrunner and ESC for less then $60 in Spain already crawling with Esc in silence 50A BEC integrated 20g of ESC https://youtu.be/jHjvxbYNvcY Combo LOW COST !!! |

Here is what he got Flycolor Francy BLHeli_32 20A/30A/40A/50A 3-6S Dshot ESC w/ LED only 20A and 40A are in stock ATM Óscar vh is not running the AM32 firmware in the video so his slow crawl is not as good. As you can see it is still pretty good and slow though. Drag brake is not as good as a brushed motor IMO. To gain a powered drag bake that will hold better will cause the motor to buzz like a servo in the examples I have seen, and has not been implemented on these esc's that I have seen. Pair this with a direct power Holmes Hobbies servo and you are good to go with out all the hassle of programming AM32. |
