E7SE wobbles at high head speed
« on: October 22, 2017, 10:01:07 PM »
Hello,

Today I noticed my Synergy E7SE has a wobble at 1850 rpms. When I run it at 1750 it is stable with no wobble but as soon as I switch to 1850 the heli starts wobbling and the tail fin can be seen vibrating. Here is the set up

CGY750
FUT 9352 Cyclics
FUT 9272 Tail
Scorpion 4035 500kv
Castle Talon 120 VH

Any ideas on what it could be?

Thanks

Depending on age of dampers and bearings, it could just be head wobble.  Try moving the RPM above 1900 and see if it smooths out again.

It did not use to that but I'll try 1,950 and let you know how it goes.

Thanks

It would be most true that it was.

Hi guys,

Just wanted to let you know the issue has been resolved.  I put new dampeners and the wobble is completely gone at all head speeds.

Thanks everyone
