FlyingGiants - View Single Post - Da-85

These samples were taken in Costa Mesa, California.

Weather conditions were sunny with a temperature was 75 degrees Fahrenheit and humidity of 61%. Altitude is approximately 31 feet above sea level (the sea is actually 1/4 mile away).

The motor is a -brand new- DA85 with approximately 3/4 gallon run through it. The muffler we are running is a Jtec in cowl pitts designed for the DA85. Per manufacturer instructions, we are running Amsoil 100:1 on 91 octane super unleaded, and if anyone cares, it was purchased at Mobile.

We *are not* running petroleum based break in oil.

Various props on the ground, cowl off. During the engine runs on each prop, the motor was cycled to full throttle, then to idle 3 times for approximately 5-10 seconds. In between prop changes, the motor was cooled off with a leaf blower until the cylinder head dropped below 100 degrees Fahrenheit.

RPM measurements were taken with an Eagle Tree hall sensor RPM pickup, calibrated and verified by an optical meter. Measurements will be posted in form of graphs and screen shots from the Eagle Tree flight logging application.

We have tested the following props (all in spec per manufacturer):

26x10 Mejlik
27x10TH (thin) Mejlik
27x12TH (thin) Mejlik
27x10 NX

Alrighty, before we start this thing, I want to put a big 'ol disclaimer on our results. These are our test results based on all of the conditions stated above, with our equipment and configuration. Results may vary. For all the motorheads out there in internetland who wish to challenge them, please spare us the drama, and feel free to post comparison results when the motor comes available.

This information is being posted as product information only, and we are doing our best to post accurate figures.

Next week when we come back from The FlyingGiants Huckfest in St. Louis, we will perform more flight tests. The numbers you are about to see are very impressive and far better than we initially imagined, and we feel the video which was posted yesterday is just a glimpse of what this motor is truly capable of. The motor has come to life with the new props we just received.

Check it out.
