They seem like the go to medium price prop. Pros vs cons? Thanks ,MM
I will need a ground adjustable prop for my craft. I will use the Hirth 30 HP as a base line and change to a Big Twin, using the same redrive . This will require another couple of in pitch vs the 2 stroke at 5500 RPM vs 4500 rpm for the 4 stroke.
I want BTB test with the same drive and prop /thrust etc.

Apples-to-apples, the IVOProp ground adjustable props are about the same price to about $300 more than the GSC props (sub 100 hp, leading edge protection, etc). Ross Farnham says the IVOProps are smooth and likes them for other reasons (see here and discussion in the 10 posts that follow). I know when Sonex LLC needed a ground adjustable prop for development of their turbo package, they went with IVO.
GSC might be great, too.

I had a GSC ground adjustable prop on the paramotor I built some years back, I was quite pleased with it.
