Naaaa, don't be scared of it, you can fly the pulse 25E so the extra is just the same, just a little more refined and smoother. I've been trudging away at the boat, got the inside intergrip paint done, the outside yellow finished, and now just need to do the bottom paint and put the hardware back on it. Then it's done. I got sidetracked today and BS'ed with my landlord about submarines, he use to be a engineer for EB, but he still won't tell me what they are made of or the max depths, so I guess we'll never know.
