A J430 is 120 hp at full noise (on a good day). 90hp at 75% power. They will fly on less power of course, loitering along.
This machine has 2 x 85 hp 4 cylinders. She might struggle at full weight if you wanted to climb. I'd imagine they are still testing it so it will be interesting to see what the climb rate is. As a 2 seater it would probably cream it in.
To be offered as an add-on kit for J430's... hmmmmm....
Name another aircraft you can just "bolt" two engines onto, except that modified Lazair from "The Gods must be crazy" perhaps.
