Okay, the clarity helped.

The Brison 3.2, which I have in mine, will leave you with no limitations either. If you don't have a burning need to spend the cash, then don't. With my Ultimate and the Brison 3.2 acceleration out of the hover is excellent. So is holding the hover. There is AMPLE power for ANY maneuver you want to do, including rolling harriers, waterfalls, elevators with change overs into other maneuvers.

Back to the Taurus. If you already had it, then I would say to install it. But if you have the Brison and the Taurus would be a new purchase I don't see the point. What many (if not most) fail to understand is that the differences between the DA50, the Brison 3.2, and the Taurus 52 are relatively minor. Most of those are in the engine weights, with the Taurus having a slight actual power advantage over both, IMO. Definatel not enough of a difference to run out and spend several hundreds of dollars extra for, or to sacrifice any value in a sale of the Brison to make the change. You'd be far better off managing the weight of the aircraft and making good prop selections.

I feel no need whatsoever for a larger or different engine from that which I already have in the Ultimate. That 3.2 Brison will not leave you wanting for more power.
