im not disagreeing with you alex but having the same counter ballence doesnt mean that the new pad will be balenced. it has got to do with the distance from the central point.

Alex, maybe I didn't make it clear in my reply. It's possible the brass counter balance part is machined to fine tune the balance for each individual sander. If that is the case changing the weight or even moving parts around as Alan posted will change the balance.
Do you guys even know what the word 'SAME" means?
Go check Ekat for yourself, like I did, instead of inventing all kinds of weird theories. Check the parts. Check the part numbers. Remove the pad from one of your sanders and see how the counter weight is fitted. I have done all above things. There is only ONE way to fit it. There is only ONE part number in the Ekat for each part and they're all the same across the sanders. There is NO WAY to make tuning adjustments. There are NO parts especially tuned to that one particular sander. It is ALL mass production. If you order one of those parts anew, to replace older parts, you gonna get one that's exactly the same and it will work fine as long as you know enough about screwing to fit it correctly.
Alan, you are correct to say that the distance from the central point is important. And your theory would be very sound if there actually was a way to vary that distance, but in this particular case, there isn't. It is a "one size fits all" case.
Brice, if the weight of the counterbalance was changed to suit a particular sander, it would have a different part number. Or do you think Festool just makes two different parts with the same number?
Sorry to sound a bit harsh, but I have had this conversation once before and it is unbelievable how people try to bend reality just to explain some misinformation by one Festool employee. No, not everything every Festool employee says is the golden truth. They also make mistakes. This one did, if Wayne recalled his words correctly.

....as for swapping the pads , is it worth risking one sander to make it do 2 things rather than buying 2 in the first place. there has to be a point where the extra effort to swap over and back pays off (also wear on the mounting mechanism) . in the long run i think 2 would be better
That's what I decided on.
Me too. I have a DS400 and a RTS400. But the DS is so much more comfortable to use due the shape of the pad that the RTS just sits idle for most of the time. The only time I take out the RTS is when I need to sand something where the DS doesn't fit, like profiles on a door for instance. That happens very rarely, but when it does it is nice to have the RTS around. However, after thinking it over, I decided the cost of that sander is too much (330 €) just to have it sit there in the closet all the time. If you use it a lot, of course you want two. But not everybody is in that position. In that case, it is nice to be able to change pads when you need it. In the very rare case my DS doesn't fit but the TS would, I'm willing to invest 2 minutes of my time to swap pads. Without compromising any functionality.

Ahhh, choices. Hopefully that's how my info will come across. For those who didn't think of it or didn't think it possible.
That's why I am very much for the idea Ken posted (btw, this subject has come up many times before on this forum), and technically it's pretty easy to accomplish, within limits. It has been done before. Anybody notice how the Rotex 90 for instance has 2 completely different types of pads, without going off balance? (3 actually, the extended delta pad is also different from the other 2). The RTS300 has 2 different pads. And there's a Black & Decker sander that takes no less than 4 different pads.
But Ken, swapping pads for the DTS/RTS400 types is ok, but I think the bigger size of the RTS300 pad would require a more powerful motor like the RTS300 has (200 vs 280 watt). Not sure if it's that easy to incorporate that in 1 sander.
