The light weight one rotor broke the silence about 30 minutes ago! It was running on the test stand for about 10 min with no
load, cant afford a dyno.
Oil pressure is 60psi, oil temp started showing at 120F and RPM was up to 5000. Vibration is not too bad at that speed. I only
balance by analysis, because the first part of testing is planed to cover things like idle stability with only one side port,
flywheel weight optimizing and general issues like oil and cooling system, which can be covered without going to max RPM.
Dynamic balancing need to be done at a later time.
What I have seen on that first run looks promising.
Pictures later.
The engine designator is RES12, and is planed to do 100hp and a FF weight of 170lb, including oil and water cooling.
