Well you can but quoting right from the web site...

" *Because the .46LA dimensions are different than a bearinged engine,
it will not work in this plane unless modifications are made. You
will need a different engine mount. Depending on which engine
mount is used, you may need to add aprox. 1/4" to 3/8" plywood
to the firewall to extend the prop forward enough to keep it from
contacting the fuselage.

It will be a slow flyer with the LA... though I've seen several set up this way... and have flown one.

It was too docile for my tastes, but then I like faster planes.
