Anyone's 55HZ fouling the 600 fan shroud?

[serpent887]

I have been chasing a vibration for Weeks...Months.... before finally stripping the airframe for a thorough rebuild and guess what...it appears the 55HZ carburettor is too big for the 600 fan shroud and it fouls - badly - introducing loads of vibration into the frame.

To make things worse I am using VBar which is super sensitive to such errors and it has driven me bonkers but now, finally I can rest.

So be advised, that motor don't fit the 600 heli without this..


Attached are a couple of pics of the scuffed carb inlet and the resulting modified shroud.

Yup done this on mine when I had a 600, dont remember it making that much difference though tbh.
