1/150 scale and 1/100 scale Typhoons

[Subculture]

3.5" will fit in either, although I have a sneaking feeling the cylinder may project above the waterline a bit on 1/150th version. It would get 'lost' in a 1/100 boat!

Andy "Subculture" just pointed out to me the other day that there is this 1/150 Scale Typhoon. Note they also do a 1/100 version.

It looks like it needs a set of props, scopes, - but could be a nice sized model.
Would a 3.5" twin screw SD fit this twin screw setup in 1/150 scale or 1/100?
