IMPRESSIVE Todd!!

How great would it be to have that setup in the Baron. I say heck with the silly FAA rules. Let's all just start putting this stuff in our certified planes. I mean really, who's gonna know that it isn't the 3x more expensive certified stuff??

Back in the hangar for a bath, sealing some areas under the plane for air intrusion. Of course, had the polish the spinner so I could see the Bonanza I just changed oil in

Absolutely gorgeous Todd - congratulations. That truly is a WOW airplane.

Agree!

Disappointed with my speeds today - not sure what to think.

Ok, previously with my old prop I was computing (no air data computer) 215 knots true at 12k ft running 13.5 GPH. I did not have good engine monitor, so I was not able to tell LOP vs ROP by the monitor - only by speed.

So, I now have brand new equipment and ran the plane to 12,500. Climb was spectacular doing an honest 3k per minute up at 140 knots indicated passing through 5k and still getting 1500 FPM at 12k.

With the new Garmin engine monitor I was able to establish LOP operation (average of 12 DLOP) at 11.8 GPH, but my speed was only 198 knots. Pushing the fuel flow up to 13.5 put me roughly around 50 DROP and yielded 208 knots true according to the Garmin. If this is real, I am not happy.

The engine runs dead smooth at an idle and even LOP up at altitude; however, it has a shake in the stick that increases with power - not RPM. I'm wondering if I could have a weak cylinder causing me to go slow and causing the engine shake?

If this is the best it gets, I am ordering higher compression pistons and new cylinders with better flow performance.

Awesome looking plane Todd. I think you are on to something with the experimental avionics and all. It's the future.

Todd,
Did you do a 4 way GPS measurement this time to take any inconsistencies out of the G3X.
You really need an apples to apples measurement of TAS. Still 208 was not what you were looking for and is disappointing to be sure. I am sure you won't be satisfied until you wring out 220 or so out of that machine.

What effect would your new prop have on your speed?

In theory a positive one, right?

No trim was changed during your avionics install, right?

Your autopilot isn't fighting any out of trim issues, right?

Just thinking of all the variables prior to all the changes....

It is mighty cold, so I know I'm burning a bit more fuel for same altitude /same power settings. My typical 14.1 or so GPH was 15.3 last week due to the cold.

I started to do the 4-way and then started playing around with other stuff and forgot. I do remember going West I was doing 129 knots and going East I was doing 289. That comes out to 209.

I don't think it is ignition related as the LightSpeed ignition appears to be working great. If you turn off the mag on the runup you lose nothing, but if you turn off the electronic you lose 175 RPM. Just don't know what to think. Looks like a call to Lycon is in order. I feel the need - the need for speed

No, the autopilot was very stable and the speed steady. When I disengaged the autopilot there was no trim needed to stay straight & level. I think the new prop is about 10 lbs heavier than the old one which could have changed the CG a bit. We have not done a W&B yet as I was saving it for the annual inspection in March since I have a new interior being installed along with a lightweight starter.

In my ROP situation a little more fuel may have given me a bit more speed since none of the EGTs were even at 50. I believe 100 is best power.

I am going back up tomorrow and will run it LOP, 50 ROP, and 100 ROP along with 4-way GPS checks to confirm.

I will strap a JADO rocket to this thing if I have to. In fact, I may just take this engine out and put in a turbo IO-580. 300 knots might be in order

All in the name of safety of course. "Honey with this new XX AMU engine, I will be able to get you to Florida much faster and therefore in a much safer fashion..... This will be so much safer for you and our kids"

I like it!

Yep! It is all about the safety!!!

Here is a neat screen shot of the HITS feature when shooting an approach. The autopilot flies through the boxes much better than I do.
