Ok guys here is the , the [>:], and the [:'(].

The plane is complete and ready. The cowl fit nice with the remote glow driver.

The La. .46 fit in the cowl and does not over heat.

The retracts and flaps work.

Range check is good.

The transmitter w/ new batteries now has 400% in operating time.

But..................

The engine just won't run reliable inverted cowled. The engine will turn 12,800 w/ 10x6 prop and 15 % cool power fuel. This combo worked well for upright in the very same engine. I tried 3 different heat range / type of plugs and 2 props. 10x6 and 11x6. To improve the idle and transition. This is an airbleed carb. At idle it is rich and at throttle up it dies instantly. If allowed to idle it will load up and die. I have tried with the airbleed to lean it out, but no success. I have experimented with 2 different types of fuel with no luck also. At full throttle and mid range operation it is ok, it just won't idle down and then accelerate w/out dying. (the fuel tank is positioned for c/l of tank to c/l of carb.

I have a bad back and my specialist told me,,,,,,,no bending so I can't have an engine that won't run reliable.

I am going back to my base engine that I now buy for new and replacement engines. I will buy the Saito .56 AAC and install it horizontal. This will mean a complete rework to the throttle servo and at least a 3 week delay in first flight. I know you will ask why not put the La horizontal. I don't have the patience to rework the fuse for the La and find out it still won't perform. I have had very high success w/Saito ,, they just work out of the box, and this is the type of reliability that I need.

What engines were used on the current flying planes, inverted,, and how are they on reliability. Jim
