Glad to hear I got your explanation right, Joe, and thanks for clearing things up once again. lol
Btw, thanks as well for your input, Editor. : )
Hope this all helps you out, Jon.
I think you may have just answered your own question, RushOut of curiosity, if there's conclusion that motors by themselves can be out of balance, what's to prevent the 'other three' motors from inducing some vibration into the system when trying to dynamically balance the forth motor/prop combination? I can see this becoming an iterative process.
I suppose it's possible that the magnitude of vibration incidence from three prop-less motors is orders of magnitude less than the prop'd motor. I just don't know.
I understand completely.Thanks Joe, nothing new there ... Moment arms, harmonics, momentums, etc. it just occurred to me that the prop in question really wasn't isolated from the rest of the system.
Not sure how I'm going to move forward yet. Not excited about taking my hubs off and on, and I don't think you can buy hubs for the new motors and QR props yet. I only see the adapters in the store.
Mirror system is not a bad route. It's the trial and error part to determine which half of the prop to tune that frustrates the process. If I could buy hubs, I'd go that route. With that not possible, I may try live balancing.
thank you for the update and sorry you had to go to all that trouble only to come across such an insurmountable problem.
Rest assured your efforts and posts are very much appreciated. You've already helped me a huge amount in understanding
the technicalities and importance of prop balancing and the fact that you've actually attempted this is invaluable knowledge.
I've just ordered an EJH rod for the 1345T although there may be problems with a permit for shipping to UK addresses. We'll see.
I also followed your instructions for the 1345T Prop installation kit from the DJI site, (not from other vendor). I ordered the kit that
was 6 rows down and 3 in as it may be different on the US DJI site, not sure.
Regarding the 45mm Olympus lens i'm using... I've done some tests and it's actually pretty good, i'm only getting un-usable wobble
when flying in a breezey wind and it seems worse when lowering throttle to track down. I still need to do more tests over the next few
days but really looking forward to giving the static balancing a go when I have the tools. Once done i'll film them like you said to look
for any play around airframe connections.
Yes, I was able to read it fine, all I had to do was expand it to read the entire message and thanks for the response.Sorry all, don't know why it came out all italic and in that grey box. Hope you managed to see my post anyway Joe.
I make one for phantom 4 and the Inspire 1 w/ 1345T props but you will need to buy and extra set of hubs , if you do not want to remove the hubs from your inspire.So to balance the 1345Ts I have to remove the hub from the motor?? No one makes a device to use that does not require that step. I'm awful nervous about going around removing hubs...
Duh. Some times the obvious is not so.Thanks...I make one for phantom 4 and the Inspire 1 w/ 1345T props but you will need to buy and extra set of hubs , if you do not want to remove the hubs from your inspire.
You can find them on Amazon.
