How much are you having to tweak standard length/loft angle?

[miatawnt2b]

I have a question for those of you who have dialed in your length and loft angle settings with the rmotion. Are you finding that it's a pretty standard change across all your irons/woods? what are you finding when comparing to skytrak data? I wish I had access to a skytrak so I could get mine set up

I did a test comparing the SkyTrak with the R-Motion. I changed the loft using the actual specs for my Taylor Made Irons but kept the default length. Here is the video: SkyTrak vs R-Motion. Going to do another test changing the length but this may give you an idea of some of the data comparison.

I wish I had access to a skytrac. I tried adjusting to club specs for a start but I just used trial and error. Kept adjusting for each club til it was close on the driving range. The only problem when I play a course TGC has default lengths so when I hit a shot I have to make sure I have the right club for my distance not what TGC has selected. Wish TGC would use my clubs but it uses the default and unless i missed something I tried to change the default clubs and TGC still uses the standard default.

So I just did a test on the club length settings and how they effect the distance of your shots. See if it helps you make your adjustments: Club Length Setting and Distance

Fantastic video. Thanks! I really enjoyed the rmotion vs skytrak. I am going to have to get my rmotion dialed in.

Great job Dean. I also find TGC is closer to my distances than the app. Interesting to see that adding length to the club adds to the club head speed and distance even though you are using the same club. I guess this is how the software and sensor calculates the shot. I am working at getting a closer ball flight pattern as R Motion seems to be more right to left than my actual shots on the range. I use R Motion like every other day and it has help me improve. Keep up the good work.

Thanks nbar...Like you, i think R-Motion is more right to left. It seems that i never hit a fade on the R-Motion but in real life I do. The ball flight just doesn't seem right. Working on another video comparing the club data (swing path and face angle) of R-Motion and Optishot.

Making the distance changes is not "adding length to the club". The length entered is distance from the sole of the club to the bottom of the sensor. If you change the distance the velocity calculation is changed since v=rw where r is the distance. The R-Motion sensor is a multi-axis sensor. It can detect the angles at which it is being moved as well as the time from when the downswing begins and the ball is contacted. The angles are the reason it is required to have the clubface square to your target line for 1 second prior to beginning your swing. This is the starting point. All other characteristics are measured/calculated from that point.

Not sure what you mean by "making distance changes"? How do you do that with R-Motion?

[nbar]

Guess i assumed that everyone knew the club length parameter in R Motion was from the sole of the club to the bottom of the sensor as stated in the setup instructions. after setting the clip up this way and measuring from the sole of the club to the bottom of the sensor then entering your club specs you can change the distances on your clubs by adding to the length parameter in the setup.

[braycobb]

Unfortunately, I have seen a number of folks not measuring correctly and then stating that the distance are way off. I have had a few questions/comments on some of my YouTube videos about this.

When I say "making distance changes", I am referring to changing the distance from the sole to the sensor. That is what modifies the distance hit of any given club. The software is simply using the angular velocity calculation (v=rw, v is linear velocity, w is angular velocity, r is distance from center to arc). The software calculates the velocity (say V1) at which the sensor is moving (easy to do given the sensor is tracking moving in multiple axes over time). Using V1, it can then calculate the club head velocity (say V2) at any given distance from that point.

For any given club, you can affect the clubhead speed calculationby

entering a distance from sole to sensor (effectively changing r in the equation) in the phone app or the R-Motion app on the PC that interfaces with TGC.

Thanks braycobb!

I have found a huge difference in speed on app vs TGC. Like 33 mph vs 75 mph for 6 iron. Did you do a comparison with a driving range on TGC and skytrack? Thanks

[golfallyear]

I was not able to compare the TGC with the SkyTrak at that time. I need to try that at some point. I just tested and posted a video on swing data (path and face angle) with the Optishot. Data is so different between them. https://www.youtube.com/watch?v=65IJBuOiiN4

[Rusty1iron]

How about doing them at different times with same club - just to get an idea? If you have 10 of each - should give an idea of difference?

[golfallyear]

I could do that but not sure it would a give as good a comparison. if you wanted to see that comparison, I have video of hitting a 7 iron on TGC and another video of hitting a 7 iron with SkyTrak on my youtube channel: www.youtube.com/c/Deangolfallyear
