Default 100 hours on engine; going strong

I have not posted much only because I have been busy with non-aviation life. (Moving across the country and building a new home sorta takes a bit of time.)

I just reached the 100 hours on the engine, with about 85 ish of it flight time. I have not had any issues with the engine or the PSRU. I typically run it at about 4500 RPM. I have only added one quart of oil in that time frame. Things seem to be going well with the set up.

Good flying to you all.

Charlie
Now, Magnolia KY.

Thanks for the update. Congrats on the 100 hour mark.

I was just wondering yesterday how you've been getting on with the engine. Sounds like it's been treating you well. Congrats on the milestone!

Are you running return line or just pressure regulator on fuel injection ?

Tom,

I am using a return line from the pressure regulator.

Default Update and new variable pitch prol

It has been a while so I thought I would give an update and share some new changes coming.

In short the engine and installation are working well.

I'll describe some things that I need to work on at the end of this post, but off to the good stuff first.

After getting a bit more and more dissatisfied with 20 inches of MAP (Manifold Air Pressure) at 10k ft. and having a Turbo which is really not being used to its full advantage, I have plans to get a variable pitch prop. I know most of the "usual" candidates, MT, etc. but I am more intrigued by the variable pitch prop hub being offered by GR-Engines out of Rostov-on-Don Russia. Ill insert a pic of their hub with this post.

http://gr-engines.ru/en/catalog/propellers/vpp-3-20

For my set up, this seems to have a lot of features that I really like. I will be able to use my current spinner and spinner back plate and more importantly, the warp drive prop blades with their hub. The system has a 5 button dashboard controller that fits nicely in a 3-1/8 instrument hole that allows you to select minimum (climb) pitch, Maximum (Cruise) pitch as well as being able to select increases and decreases a degree at a time. Plus of course it displays the actual pitch at any given moment.

In case readers are wondering, I have spoken to the folks at Warp Drive and they (understandably) take no position on this.

There are a few older versions in the USA on Trikes but for the most are in use oversees. One unit has been sold to NASA for use in the ROAMX program.

I have a prop extension in use already and this will require me to have a new extension made to fit their hub.

It will be a couple of months before the system and extension are ready to ship and more time after that to install. I honestly have no expectations things will come together anytime before December. Which is actually good timing for me as I have more non-aviation obligations right now than I have time for.

More on other squawks in separate posts.

George,

At first I thought you were kidding. Yes, there have been about 200 posts with updates since I first flew last October. Tons of details there for the curious....

My empty weight was 1036. As far as speed goes, I always want to put some context around "speed". As I am sure many want to see if the "Honda" produces enough power. As you know there is much more to speed than the HP the engine produces. The main limited factor to my top speed is really not related to the engine. They are:

1) A 2.33 ratio reduction drive. With my self imposed top RPM of 5000 this limits my top propeller speed to 2150. So....imagine comparing a top speed of a plane that is turning a prop at 2700 rpm compared to one turning 2145.

2) I have 6 x 6.00 tires.
3) No leg or gear fairings.
4) A fixed pitch prop.

Which is why I am ordering a variable pitch prop. I also hope to soon be able to get some flight time with other RV6A and do some more flight comparisons where we can match prop rpms.......

I would have to check some notes but I think I see 150 mph at sea level at 2060 prop RPM.....

Sorry did not see the other post. Thanks for update. From video sounded good. Thanks for quantifying speed... The CS PROP will be a great change. Good luck.
