Most of the parts arrived this week and I got a variable temperature soldering iron for Christmas, so having done it once I am pretty much most of the way through not repeating the mistakes I made last time.
I’ve used acrylic conformal coating in the past because you can solder through it easily. Not great for wires though, but maybe nothing is.
I just finished a copter today that I’ve been working on all winter… Supposed to be the final product of all the testing I did w/ other copters over the winter (testing the new kakute mini and all the vibe issues I was having, etc).
This copter has the least vibrations out of any of them… But it has the lean issue very badly. It’s not really flyable w/out GPS signal, because for whatever reason, having GPS makes the lean issue go away for the most part. W/out GPS, it’s pitching forward and leaning to the left more than I can compensate for, after I’m flying for a couple minutes.
I really don’t get it. Vibes are around 5 in the logs. My other kakute mini copter I was working w/ all winter is 15 on average and peaking to 30+. It had the lean issue, but much less than this.
Maybe I’ll try rounding up everyone w/ the issue and see if we can get logs and figure out if there’s anything we can do about it. Marty was recently posting about the issue on his copter and me and a couple other people quickly blamed vibrations. I was completely sure it’s vibrations. On that last copter, as I fixed the vibrations, the lean issue did get better. But now I’m not sure again. I don’t think it’s possible to get them lower than they are. so frustrating.
Hi Andrea, obviously yes!
I used the ones supplied with the nano v6 omnibus and rubber ring on the nylon stand off. Double foam on the barometer. I thought a 3 “was less critical than a 2”.
I’m waiting for the usual, I think they are indispensable on any nano copter
I set them to 0 - which means basically go as fast as you can. On big copters this is a bad idea because you can overload the motors but on small copters I don’t think there is much of a downside. Autotune will set these base on the fastest response it sees from the vehicle when twitching.
Yes, that guide is great! I think his limits on the graphs are for 5" props, but you can interpolate down to 3"… I haven’t tuned from scratch in quite a while, but reading through the guide, I think it covers everything.
