Are there any new technology high power high speed 90 degree angles available cheaper than the standard helicopter ones..?

I'm looking for the cheapest and lightest 90 degree angle available to buy which could transfer approximately 200HP of power to a prop hub at around 3000+ rpm. Used outboard marine prop angles or bike shaft drive angles would be an option too but it is questionable if they would endure prolonged high power high speed of a variable pitch propeller or be light enough for aircraft use. Another option would be to find some junkyard helicopter tail hub angles, but the high power ones tend to be either slightly heavier than needed or have a turbine attached to it.

Any ideas?
