RE: Most powerful 46 size engine ?
Don't overlook the TT46 Pro. With a Tower or GMS 47 muffler fitted, these engines will eat an OS 46 FX/AX for breakfast.
Most of our club members have ditched their OS and GMS engines now in favour of the TTs and are really enjoying the extra power and spare change in their pockets.
They also last a *long* time, much longer than the OS engines.
