going to do abit of glow power boating Kennith ? are you wanting this particular hull design for speed or just the scale look run around ? i find z-epoxy 30 minute cure is the best for building gives you plenty of working time and it does set off within the 30 minute period. there are plenty of fuel tank sizes available so its just a matter of taking a measurement of the tank area then match a fuel tank size up. Sullivan Brand is good. and i must say CMB 67 is great.
