The 601 is not a heavy plane, and the brackets that connect the longerons to the firewall and engine mount are not designed for anything of that potential weight and torque. The Stratus is a practical limit for weight and the Jabaru is a practical limit for HP. I'd be reluctant to combine a package that did both. The consequences of that type of decision could be fatal weeks, months or even years later.

It flies great on 100 HP but if I can swap in more HP at the same weight, that's a good trade for me. I'd like to put it on amphibious floats someday too.

Im getting a new intake manifold that uses the throttle body and thats it. You can get a different mod that is fuel injected with the direct fire ignition. As far as the standard Stratus setup goes, before my engine had 1 hour on it I had to : 1. Have the heads and valves done (talk to Frank ;) 2. Replace the distributor 3. Replace the alternator 4. Replace the backup ignition module 5. Im going to be replacing the carbs, (throttle body) but the throttle setup on my bing carbs is such that you end up "Pushing for idle, pulling for power" - opposite of what it should be. This happened due to some starters being longer (mine) and causing them to put the throttles on in a manner that fits. The byproduct being a reversed throttle setup - unsafe and a pain to fix. The current design of the intake manifold + carbs means that you will NEVER get all cylinders to have the same mixture. The best you can do is get 2 out of 4 burning properly, the other 2 will be too rich. Balancing two carbs is also more trouble than its worth in my opinion, Ill take simplicity over complexity any day - one carb to two. Having the ability to adjust the mixture from the cockpit like most spam cans also is something I like. Stratus is a good company and has been responsive to most of my problems and questions so I have nothing personal against them. I have just had too much trouble for what I paid. My two cents, which is about what its worth ;) - Andy On Mon, 18 Oct 2004 19:30:51 -1000, gary wrote: >--> Stratus-List message posted by: "gary" > >Andy, >I heard that the Aero V carb doesn't work well under pressure.

I would like the direct fire system 'cus it removes what is now a single point of failure for me...I.e the distributor...Both of my GM modules are built into the distributor. But its good enough and I'm probably going to sell the plane in a year or so.
