In a spin

[Adrian]

Just been trying me new scaler out and am stumped a bit. when i spool it up as it get light on the skids it starts to rotate clockwise (from tail in).

Now ive tryed the gyro changing it from green light to red and still no different (gp750) must be somthing obvious ,the tail rotor is on the left and the main blades swing anti clockwise ,so opposit to a 600/raptor

I assume it's the REV led you're changing? Take a peek here to clarify.

Are the tail rotor blades spinning up into the main blade downwash?

[Adrian]

all the rotors are correct just cant get it to stay in the setting i want, perhaps id better try another gyro as it dont seem to work like the other 3 gp750 i have

[Mart61]

Could be a dodgy gyro I guess...

[robgt]

If it's not the gyro reversing, and the rudder is all setup correctly, including mechanical linkages and transmitter setup, then maybe you could try one of your other gyro's on there to eliminate (or prove) the gyro in the equation?

Cheers,

Have you got roughly the correct amount
of left rudder pitch on the tail blades to
offset the clockwise torque the blades are making?

[Adrian]

Yep all seems ok martin,james did have a look at it and seems all ok. im going to try another gyro later off one of my others

I will pop in later mate, after work, i was running late last night and didn't get chance, i am not out tonight as my baffle is rattling around in my 700's muffler

I always set my helis up out of
heading hold adrian. i get the pushrod bang on
the correct length so tail doesnt rotate.
I then switch into heading hold and fly.
I know james and a few others who dont
do this prefering to set blades at neutral pitch
then just fly in HH. I think though in this instance
on a scale model my approach would be more prudent.

I agree Martin

Well ive just changed the gyro.
Ive took one out of my others all set up ok green light on ect,once fitted inside the other ,no green light just red! and the one ive just took out and put in the other heli which had a red light on has gone to green!

This meens i take it there must be some other problem other than the gyro ? .......

Yeh your travels on the gyro gain channel
mate check them should be about plus minus
40 ish percent.
Or maybe you have put the gyro gain into wrong
rx slot. Sounds like you cant select heading hold
and are actualy in rate mode on gyro hence slow
piro.

[Adrian]

Its pluged into the right channels martin ,single yellow (gear) the other rudder,my % are +/- 53%

[LipolyGone]

When you toggle gain switch does the light go green?
Did you copy a model memory or start this setup from
a new unused memory slot?

[Adrian]

when you go to change the % settings and flick the switch it changes green.
The rx and gyro have been used on other helis and ive just reset it on a used model memory
