RE: What to do with a 40LA
The Model Tech Extra 300 is a great home for both the .40LA and the .46LA.
I ended up putting my .46LA in the Model Tech 300.
Even though it calls for no more than a .32 sized engine, the size and weight of the .46LA is identical to the .32 O.S. engine.
Most .32 sized planes should be able to accept the LA's.
