I agree, really it is a 2S boat. It seems sellotape ultra is different from diamond. Ultra leaves no residue. But that hockey tape sounds a good buy.
Congratulations on surviving your first outing with it.

I got mine to go quickest on a large, 3 acre lake. It was big enough so that on the return runs the wake had dissipated. Even so, I couldn't max it.
Tried 100g of ballast in mine today, to counter the battery. Slight improvement, but she still jumps. Also I need to add a hump to the cockpit as it no longer self-rights.
Maybe some trim tabs are in order?
