well...you'll save more wieght becuase the LA has plastic backplate....or at least the oncsI have do.
You can even go to a magnum .52 or tower .46...The ball bearing engine saves me money from having to buy weight
for the nose.

The TH .46 has a big muffeler..it bascailly gose right through if you take out the baffling..when noise is not a consern.
I don't really know what other people where talkingg about....saying TH engines are so and so.
If you know what you're doing and know what to look for. The tower .46 has plenty of power and will stay tuned.

I imagain the porting of the sleeving are different from manufactures to manufacturers. This too will also effect HP or performance.
I know. i got a stock T-maxx to pop wheelies by messing with the porting..it works..but i wouldn't recommend it unless the engine
is on it's way out. R/C car nitro engines has porting up the wazzoo compaired to airplanes.
A .15 or .18 car engine can produce 1HP...but they operate at higher RMPs . Up to 30000+

It is dangerouse to mount a prop to a r/c nitro car engine..becuase props are not designed to spin that fast.
It'll break apart and can posisbly killed.
