RE: OS 33GT Gasoline Engine for Pattern
Completed the installation this morning and tried to get the engine started. Well, easier said than done. On the bench the engine worked simply and easily but in the plane, for an unknown reason, it was quite a bear. I suspect the CDI module programming may be an issue. Also quite strangely for a gas engine, it started backwards several times so ignition timing could be off a bit.
However, once started it ran well putting out gobs of power. I decided to run the MDK 18x12 hybrid prop. My SAP 30 cc would not turn this prop without bogging down in the verticals so it was very interesting to me to see the OS33 turn this prop with great authority. I didn't measure rpm...... By ear I'd put it around 8300. Most importantly, the verticals were effortless but I have the engine slightly on the rich side. Two flights were taken today and both were really strong on power.
Got to figure out how this CDI module needs to be treated......
