PM! haha.. "moderator"... i kid, i kid. Can you point me to a post with all the info and pics? The only thing I have done with my posts, is change to the RB5 posts using the wider chassis holes, and am running the RB5 battery strap.

I thought I would try to get the 6 a little lighter for stock buggy and I got down below 1499. I actually got it down in the 1480's but didn't drive it that way since I believe too light is not good for a number of reasons (not legal being one). I was in a hurry to get to the track before it got too busy so I quickly added some weight up front with the low profile servo to try to get it to 1499 for a starting point. This buggy was at 1595 when I first built/drove/weighed it and being down at 1497 makes a huge difference with how quick it is both bottom and top end speed. Didn't get to drive it much but it is FAST! Being able to add weight where/when needed will be nice. The point of all this...... for the RB6 haters, it can be very light with a little effort.....

How about trying it off the kyosho pit mat and on something solid?? Would like to see if that makes a difference.
