R44 Tail rotor gearbox question
Hi all,
The 44 Astro I have been using was seeping a little of it's tail rotor gearbox oil, but nothing bad, had it checked and refilled yesterday and today it managed to vent nearly all the oil in 1.8 hours flying.
Engineers are a bit baffled, there is obviously a bit too much pressure in there for some reason, anyone experienced any similar problems?
Thanks
