Thunder Tiger 54 FS. Test Runs. Part 3/3

This is a bit longer test run video with some more detail of the tuning process. You can sometimes spend a lot of time tuning and fiddling around with the engine and empty a can of fuel. Watch to the end for the test flight take-off.

I had this engine for quite some time. It ran reasonably well but would almost immediately die with inverted flight. Could only fly it well 'upright'.

Hi. Sometimes the four strokes battle upside down. The type of plug and nitro content makes a difference. An onboard glow system usually solves the problem. If the engine has low compression It will also affect the low idle speed in general.
