Ah, I guess I should have used 300lbs, the Wraptor's rated capacity.
That'd make for .54hp/406 watts for 5fps ascent.

That's about where I am with a medium saw on my hip, since I start out at 248# getting out of the shower.
I think it is funny the number of people who get bunged up about the tool. How many of them have a 088 or 3120 that they use a few times a month? How many gear-heads have bags of stuff that they tried out and rarely use any more?
Since I have the tool on the truck I use it if it is not easier then climbing the tree, or two or three locks up. I am more likely to set blocks high in adjacent trees vs natural crotching. I'll work a side of a removal down and go back up with the Wraptor. It is much easier to clean rigging on big jobs now, I had been finding myself not wanting to put in a center block and redirects for big wide trees, now I choke the orange rope and use it as an elevator line.
It does take some of the skill out of the work, I don't look forward to getting the MarBars out if for some reason I cannot use the new tool. Difficult transfers stem to stem or tree to tree are rarely in my playbook these days, even though I find them fun. Why take the time to swing a jamknot over, or mess with a johneyball in the tree? I can descend and set a new line and not have to muscle my why over a near horizontal line.
i can see not wanting it because you will not use it enough, but being so wrapped up in your physical prowess to reject it summarily is silly.
I was a skeptic when Paul sent me the demo unit, and was quickly sold by how practical it turned out.
As for power, i think it is over-built. It could use a smaller, more compact engine. The pictures of Grahme's "Scotty" sure seemed smaller then this.
