Hey guys,

I have a goblin 700 with a DFC head. I have done my research and I have come to the conclusion that something is not setup correctly in my heli.

Here is what I have

DFC Goblin 700 - one of the original ones
Quantum 4530-500
Kosmik 160
Vbar silver
torq HV servos
using a DX18

now my friend did the test flight, and he set it up at like 90% throttle, then 100% throttle for idle 1 and idle 2. I tuned it down to 70% throttle, which seems the be the head speed I like but now I get this terrible wobble.

Any ideas on what to look for in the head? Unless the DFC needs 90 - 100% throttle with my setup then I will go to a HPS head, but that dosnt seem right to me.

I will upload pics of my Vbar settings later tonight.

Thanks guys

It is a wobble, but only happens when I move either the aileron or elevator.

As for head speed I would have to calculate it out.. using mr mel's calculator with 100% throttle I am around 2400 rpm at beginning of flight.

maybe I do need to go to a HPS head
