I have one that dont hop,where are you adding weight? I run a Lynz cut prop

 

[Ken Hildreth]

You cannot add weight to the sponson tips. put it just in front of the radio box.

I sold mine a few months ago but never had any hoping issues nor did I run weight in the boat.sound like you have other things going on

Check the running surfaces for a hook. Mine had a slight one. I filled and and sanded it a couple weeks ago and it helped settle it down.

Edit, I didn't read the whole post where you checked the bottom already.
