A turboprop bonanza is about 300

A Soloy conversion with a Rolls Royce/Allison 250 gas turbine is 450 HP

The Rocket Engineering conversion uses a PW PT-6 derated to about 500 hp. I think this conversion needs a B36TC, which has the longer Baron wing as standard.

A Bonanza's factory engine (6 cylinder Continental IO-550) is 300 hp.

I have a few hours as PIC of A36 Bonanzas and found them to be docile, predictable, and responsive if flown within the limits of the POH. I suspect the V-tails were no different.

If I’m not mistaken, the B36 turbine also had tip tanks. Anything operated within the confines of the POH is docile. The v tails however were very easy to find yourself outside of that envelope where as traditional design is much more forgiving.

Point taken on the V tails. As I mentioned, never flew one.

I will say this, when I actively flew I was VERY mindful of limitations and flew strictly by the book for two reasons:
  1. More often than not my wife flew with me
  2. I was a nuke and operating by the book is drilled into you starting day 1

There’s usually a 10% buffer built into the limitations of any aircraft in case, since we are humans, we find ourselves outside of those limitations for short periods it isn’t always catastrophic. It all depends on how far you go. A small flap over speed. Rpm overage egg limitation. Exceeding Va it’s all built in. It’s continuous operation outside that envelope that is the danger. But yes always strive to be inside that envelope. Even with a buffer, there are no guarantees.

Actually, the "aircraft engine" being referred to is a V-12. The first two cylinders were sawn off and customized to make this V-Twin. So what is that, 16% of the original engine? Something like that.

Did you even look at the video?

There is nothing Rolls Royce about the engine in that motorcycle and it most certainly is not a V-anything.

It's either a Lycoming or a Continental flat 6 from some wrecked GA airplane.

20 years ago I’ve taken a plane to its Vne and I imagine it had to have at least another 30 knots in it before the wings started to rip off

Most POH’s have a Vg diagram that looks something like this. At Vne, you were already at the limits of that buffer.

I was referring to SirHr's link, and yes I did look at it, as it is quoted here. If that is NOT what was being discussed, then 'my bad'. I thought it was.

All in the context, I guess.
