Humidity effects on the startup of mini jet engines
Hi, I have 3 RC planes using 220N Thrust mini jet engines. They started up perfectly everytime. But nowadays the humidity levels are over 85% and all 3 engines they are not reaching idle rpm. During startup they shoot out flame from the tail and the exhaust gas temperature exceeds 950 C and the ECU turns them off. The burning cannot be sustained inside the combustion chamber and the RPM stays stuck at 26000 and does not reach idle.Can anyone please guide me on how to identify the problem, troubleshooting and solution? Much appreciated.

It would have been good if you told us what brand of engine it is. I would first write down all your settings to have for a reference . Then I would call the people that sell them and get the settings to try. I have only had to make adjustments for acceleration on high humidity days . Dan
