Ron,
Thanks for looking into this. I had called AeromarineRC.com for my info but only got the same answer. They seem to be the ones that are the distributor.

I just bought a SW 36 off e-bay but I still want the MM 18. I have two kids and I can see myself and them fighting over the control! It would probably more fun to have two boats that respond differently in water conditions for a little racing.
