TREX 700 tail wobble up/down

[Si Goodchild]

Guys,

I noticed last night that there is a slight up/down wobble on my TREX 700 when running on the lower of the 2 headspeeds I use. It appears to go away if I up the headspeed. I'm thinking it could just be that the headspeed is a bit low or perhaps the dampers on the way out or perhaps the tuning is a tad rich but I'd appreciate your thoughts. The details are:

• TREX 700 Nitro Pro, OS 91 HZ PS + Align Pipe.
• CY Radix 690mm main blades, Align 105mm tails.
• Align Governor normally set to 60% ATV on a DX7, which I believe sets a headspeed of 1650 rpm.
• The higher setting is 66% which I belive equates to a headspeed of 1750rpm, and seems plenty fast enough to me!

I hope you can advise,

Si G

Up and down on the tail 9 times out of 10 equates to a too low headspeed. Reading what you've written I think you've answered your own question

Smashing, many thanks for the advice. I can tune that out with a couple of clicks on the tx!
