I don't think that I've got any good "under the hood" shots but I know I've got one when it had a Sikk in it.
As far as the nitro boats go, there's quite a few of them, mostly .12 powered and one .21 'rigger. Two of them have never seen water and only tried to fire up a couple of times.
OK, this shot was when I first had it together. I bought it used but never saw water. The CG was way too far forward by about 3". I was also a newb gas boater at the time as if you look really close you'd see that I hooked up the fuel line accidentally to the primer return fitting. Boy, I sure felt stupid then!
