Thanks Patrick that makes number 2 in 3 years. Oh well, too late for me I've gone down the conversion path already.<br />

I just looked at the flyer from Oshkosh '10 says "max engine weight 185lbs". The Raven 1300SVS meets this in real world terms. The Rotax also does, but only by 8-12 lbs less then the Raven. The Raven will perform close to the 912, but the 912s will leave it way behind. Speed for all is due mostly to weight and drag, so clean it up. I have been struggling with this since I started building and have spoken to a number of different people with first hand experience with the Raven. A 912 it is, a…
I just looked at the flyer from Oshkosh '10 says "max engine weight 185lbs". The Raven 1300SVS meets this in real world terms. The Rotax also does, but only by 8-12 lbs less then the Raven. The Raven will perform close to the 912, but the 912s will leave it way behind. Speed for all is due mostly to weight and drag, so clean it up. I have been struggling with this since I started building and have spoken to a number of different people with first hand experience with the Raven. A 912 it is, a 912s its not. But you can add the Turbo if you must. That will put you over the 185lbs by a bit though. The one thing that the 912 does have in spades over any conversion, is that YOU are involved in it manufacture, so you can use low quality parts, heavy parts or poor performing parts. The factory does not allow this for the 912.<br />
As for tinkering, none of the guys I've spoken with do much at all... I asked.<br />
<br />
As for mid time 912s cheap.. saw one in 3 years, it has already sold.But it was a low SN model so low tbo and the parts are not insignificantly priced. If they are so readily available then someone should start connecting people with them.<br />
<br />
If you have not purchased anything yet, and if money is an issue, build the 750, engine choices are more varied.<br />

I did plans build. I took the long way around and drew out the geometries (according to the measurements) on poster board then cut them out. Traced it on the wood and cut that out. You have to be very careful about tracing the image. CAD draftsman tend to zoom in and out when drawing this changes the size the image will print out. Therefore, its better to go by the measurements instead of the image.

You missed the discussion we had a couple of weeks ago concerning vibrations, start-up shaking, and abrupt stops associated with the high compression 912ULS 100 hp..... Any airframe is limited to the speed at which it can cut through the air or forces it can withstand REMEMBER THAT. There is such thing as overpowering an airframe. The performance the 701 can provide can easily be accomplished with the Rotax 912 80 hp. I can expand greatly on this reasoning but I'm not. The factory demo went for…

The factory demo went for its first 1200 hours on a Rotax 912 80 hp. However, it seems, the new ring mount makes a difference (concerning vibrations) with either engine; especially the ULS......

Your best bet is to follow Barnstormers, there have been a few 80 hp rotax's for around $8000, with low hours. I do not want to knock Jabiru but it you want performance you will want to use a rotax.<br />
