I have recieved a little feedback and suggestions from several people on Rctech and in email. Here is a run down so far.

1. One suggestion was to include some thin orings to take up the gap between the clip and the strap if a thinner lipo pack is used. I certainly may be doing this soon.
2. Sand and glue the edges, makes the product look even better and strengthens carbon laminate.
3. Ream out the holes for the posts on both ends just a little so the straps can be removed a little easier. It also helps to bevel the edges a little.
4. The balance port may need to be enlarged a little depending on where this is located. I think I will make an adjustment in the design and start making this hole a little bigger.
