I thought the gear rations were to high for the Weber as well. I thought it would be better from 2.7 and lower.
how did you determine the ratio for the Weber and would you send me any pictures you have of the Weber setup? email [email protected]
Also are your gearboxs clones of the Autofight box?

I am missing something in the translation. This was your first post. The Weber 750 is the 4 stroke.
Good on you jonathan! Shall we go into the reason the Autoflight gearbox on your customers craft was wrecked? I offered your customer a new unit at cost, a good offer seeing as I didn't wreck this unit. This engine was assembled wrong and the customer told me it ran so bad he thought it was going to jump out of engine frame. You told me it had run three minutes, your customer told me he had already run it some time like this at his place. No gearbox is going to stand up to this punishment. The rubber drive was destroyed this points to a severe engine resonance issue i.e. the plug leads on wrong or cam timing badly out. Something a " mechanic " should be able to pick up!
I saw first hand this engine in question and it shook so bad I was concerned about the airframe afterwards. I told the owner... Why would you run this with the prop on with this much vibration ? ..... And advised to just run it propless till he could get the engine to run normally, THEN put the prop on it.
Seeing how much that engine shook, it does not shock me that the prop shaft broke. That engine was run for what I would guess was at least 2 to 3 full hours worth of running, in the quest of trying to get it to run right, before it was ever loaded up and trailered to Automan.

What does make a company german? (owner, papers, past, etc)
I have been in the gyro scene since 2K and kinda know a little about it and the people that are regulars in the action.
Lots of trenches here, many shooting from the hip without deeper consideration on matters.
Dismissing others (not the friendly) achievements is common in our midst.
Reading the books, I have learned that many reconfigured old ideias and presented better versions of what not, which I think is great.
But if something is too similar to a product, the "original" owner will rant and rave, you see, this is not public oriented but, more an ego trip than anything else.
I go to chinese restaurants, all pretty similar with different tastes, cantonese, HK, etc. The owners, sometimes, are not chinese but still, they are chinese eating places.
So, if an american manufacturer goes to China and makes his product there, will we assume it is no longer american? Can it be made better?
German cars are taken as the best around, as for all machinery made there, American cars used to be the consumer´s dream all around the globe, untill Asia opened up the Cornucopia . . .
Here in Brazil, I had some fierce resistance against "my" "american" gyro project, they said the "national" gyro was better: spain in origin, bensen based, VW powered and I still look for its domecity . . . but you know . . . stuborn is who stuborn does . . .
I would love to see our little machines more popular, available and every little piece of help is welcome, but hey . . . I am not a manufacturer yet, so . .. what do I know?
Lets get these PRSU´s out in the open and see them fail or succeed at work.
As for the reversed engineering thing . . . we all copy God, he invented Nature and that is our source of information . . .
They're betting it's not worth Neil's time & money to fight it.What are you or we going to do about it?
They're betting it's not worth Neil's time & money to fight it.
Personally, I wouldn't buy anything from a company that steals from people like Neil. No matter how cheap it is...
