Hey guys,

here is the answer to the problem:



kid tt01 was right, I hide it all behind the Lipo and like MENTAL DENTAL said under the top deck (but not attached to it).
I was very happy to be able to place all the weight in the center line, or near it. For that I put the esc and the receiver a bit more to the outside. The "weight tower" near the antenna is not just a straight pile. The upper three weights are set off to the centerline.
