Proboat UL19
For some reason the UL19 has a larger prop fitted than the two other boats and the Blackjack has an Octura prop which I got from Prestwich Model Boats and goes very well.
The motor in the UL19 is the same as the one in the Blackjack.
My theory is that as the UL19 is a hydroplane which when set up is heavier at the bow and will need an extra burst of power to get it up on the plane.
