Thanks

Here is a Saito FA-180 installed in the Rascal 110. It barely fits. It is 138 mm from the prop hub to the back edge of the carburetor and 113 mm from the crank C/L to the top of the ricker covers.
A gas powered Saito FG-30 would have a similar footprint but only puts out about 2.5 HP while the High compression FA-180 with CDI and methanol makes about 3.25 HP.
