Brennan Maxwell Posted April 23, 2019 Report Share Posted April 23, 2019 (edited) I've been working on getting my rig into dynamic balance for a while. I am able to get it close, but I don't think I'm dead on. I searched the forum for dynamic balance and found surprisingly little info. There was a post with a seemingly dead link to a PDF about dynamic balance and that's all I could find. I'm flying a GPI Pro Gen 2. If there's anyone out there with current info on achieving dynamic balance I would love to read it. Thanks!

Premium Members Geoff Owen Posted April 23, 2019 Premium Members Report Share Posted April 23, 2019 Hi Brennan, Chris Fawcett did a video on Dynamic balance a while back, so you might be able to search his posts to find it, or perhaps a general search in google may find it. DB in most cases is found with the trial and error method, yes there was a document published, I think Jerry Holway was one of the authors, it was developed to be used with a palm pilot many years ago and I think it was more designed to work with the tiffen product of the time so some of the elements weights were a know factor in the actual program. I never used it but I think that you had to know the weights of all your components for the palm pilot to give you an answer. I doubt that it would help you much if you found it. DB is all about the relationship between your battery and Monitor and the force they exert on the post as they are rotated. Trial and error is your best bet as each rig will differ slightly with different weight monitors and batteries etc, some people have their monitors higher up the post some keep the monitor low, some people have 150 amp batteries some have 90 some have vlock some AB. So it's difficult to give you any suggestions on how to configure your rig. I don't know much about Pro rigs but the tiffen rigs give you a lot of ability to change the battery/monitor relationship as the battery and monitor are independently adjustable being able to move each component closer or further away from the center post. In Chris's video he suggests that you position your monitor where you want it and adjust the battery in or out to find DB. The important part is to understand what DB is, Chris's video does a fair job of doing this so it's worth watching. Here is the video. Good luck.

Brennan Maxwell Posted April 23, 2019 Author Report Share Posted April 23, 2019 Thanks Geoff, That video is great. I've been able to get it to that very close stage, but I have trouble getting it perfect. I'll keep working on it. I also want to try to move my monitor higher and that was really pushing my brain on which way everything needs to go. He explained that well in the video. Someone told me that if you test your drop time with the rig starting laying sideways rather than the lens pointing at the ground it gets you pretty close. It has been working for me as a quick and dirty way of getting it, but I want to get it dead on. I'll take any other pointers out there. It's always good to have more info.

Premium Members Jerry Holway Posted April 23, 2019 Premium Members Report Share Posted April 23, 2019 whoever told you that... well, it helps with static balance, in that case, fore-aft balance... A rig in dynamic balance is also in static balance, so it doesn't hurt to do that, but just watch Chris's video, it's all you need. Quote Link to comment Share on other sites More sharing options...
Brennan Maxwell Posted April 24, 2019 Author Report Share Posted April 24, 2019 Haha. I agree with you about it not working for dynamic balance. It's a nice thought that it would be that easy, but this video is much better. Quote Link to comment Share on other sites More sharing options...
