Pre weight and balance
Before we finish the engine cowlings and paint them, we need to know that the temp inside the cowlings will be oke.
So we went outside to do a test run.
I start for 5 min. A taxi test for 8 min playing with the throttle. Then a quick run up for 1 min. The temp stays in green, but almost to red. So conclusion is that it should be oke. But for sure I open the oil cooler a bit.

We made a strong cradle to hold the horses at a safe way in the garden.

Nice overview...almost finished engine compartment.

First sound in the garden.

Everything stays in green.

The temp of the cowling after the test run was not that hot. So we are satisfied.
