Joe, I didn't read the articles. But since I have a Hirth I thought I'd comment.

GO WITH ROTAX.....

Tons better parts and service. And a lot of people are more knowledgeabe about Rotax. How are you going to get service for Hirth in your country. Or is it a state? Actually what is PR considered.....beside being an island. :)

Rotax I would say from just Listening to other peoples conversations. But I am not a Pilot so what do I know! My 2 cents today. MJ :)

There is a "truth in advertising law" in the US. IT appears there are enough of people out there who have not received near what Hirth claims they should get. There is probably a large enough of Hirth owners to file a class action suit. Judges are elected. Large number of voters complaining gets immediate attention. Law suits get company's attention. But I would imagine this and other forums are putting a hurt on Hirth profits anyway. I seems they would really be pushing the sale of parts and have them in stock at suppliers. Just thinking outloud... better go wash my gyro.

I have had EXCELLENT service and help fro Recreational Power for my Hirth 2703. My Hirth problems were mainly caused when someone before me put oversized piston in undersized cylinders. The NIKISIL cylinder walls held up very well when the piston melted over the rings.

I fly a gyro with a Hirth 65 hp and another with a Rotax 40 hp. Both are amazing machines when you consider the power to displacement/weight ratio. I change the plugs every year, clean the airfilter each spring, and make sure they have fresh gas in the tank. They start every time and are amazingly reliable. What a difference from the early days with Cuyunas. We were lucky to get 5 hours without an engine out. It's probably not smart to say it but I haven't had a problem that wasn't due to improper installation in years. I would ask anyone who has strong words for or against a brand how many hours they've actually flown behind one. This is a small industry with a lot of hearsay and gossip that masquerades as wisdom.

I know jack sh*t bout Hirths,only ever heard one running and it didn't sound good.
But I got plenty of praise for the rotax,2 or 4 stroke,don't reckon they can be beat for power to weight,power to fuel burn or reliability,solong as they are operated within specs.The only down side to the 4 bangers would be their initial cost,but you do get wot you pay for.
