The problem is that there aren't very many syndicates around in the rotary world. There are lots for fixed wing but very few for helos. I looked for ages to find one in sensible driving distance but had no luck, so I wound up buying my own R22. That was 3 years ago and I have never regretted it although the economics do not stack up as I only average 50 hours or so per year. However the sheer convenience of owning makes up for it.
I have a third share in a f/w aircraft which is also under utilised as between the 3 of us we only do about 100 hours per year. Too many aircraft, too little time I guess!
