Not an answer to your question, but I am curious, what are all the differences between the new formula and old MB hulls??

The .21 RG looks like it has real good power and RPM for this size boat...not sure how well it will fit.

I think most folks running the 1/12 RTR hydros that upgrade the engine, stick with a .18 because it is pretty much a bolt in swap. Most use the .18 CVRM (1.35hp), and some use the .18TZ (stock with 1.8hp, but some folks swap the head to a water cooled CVRM head, not sure how much that affects HP).

I have no idea how the new Dynamite .18 engine proboat is using compares to the CVRM, or if it is even available seperately yet.

not much...the hull is straight in the rear instead of that flair it has and of course flex shaft... the old miss budweiser feels alot stiffer than the new formula hull..

Hay Lydizzle!here's a guys I know that put a O.S.21 turb in his boat plus he'd added an adjustable prop and strut system too. All the info is there. The only thing I dont like is he's put the motor on a side slant.[&:] I'll post pics of my .21 thundertiger conversion and the motor sit wright and made a custom head too[link]http://www.rcuniverse.com/forum/m_4899766/tm.htm[/link],not like the ones I see on ebay that guys are selling.21 conversion and they hacked up the cowl too.[X(][:@] Here's three different boats with the.21 in them. Two missbud old hulls,the other is the flex drive one.
