Ok, I just got an answer form x-cart for the solution on 4.1.9 and here it is:

In order to have the weight removed from the product description page but still be calculated for the shipping you need to modify the "skin1/customer/main/product.tpl" on your server.

Find this code:

----CODE----

{if $product.weight ne "0.00" || $variants ne ''}<tr><td width="30%">{$lng.lbl_weight}</td><td nowrap="nowrap"><span id="product_weight">{$product.weight|formatprice}< /span> {$config.General.weight_symbol}</td></tr>{/if}

----CODE----

and change it to this one:

----CODE----

{*if $product.weight ne "0.00" || $variants ne ''}<tr><td width="30%">{$lng.lbl_weight}</td><td nowrap="nowrap"><span id="product_weight">{$product.weight|formatprice}< /span> {$config.General.weight_symbol}</td></tr>{/if*}

----CODE----

You can also change the code in your Admin area in the "Edit templates" section by following this route "customer ->main -> product.tpl" and perform the above mentioned change there.

Please, note that the incorrect changing of the templates code may lead to an incorrect display of the page.

Hope this can help someone else. It's easy - even I got it to work.
