could someone please help me with my tail grrrrrrrrr!!!

[loz]

ok guys, i have a trex 450 sport, dx6i, gp750 gyro and cant seem to get the tail to hold, i set it up in rate mode and can get the tail to just about stay put with a little trim, but then if i switch tx to hh it moves the servo and is spinning to the left, i know its probably just tweaking things here and there which i have been doing (honest) but i just cant seem to get it right, is there a certain procedure i should be doing???

[loz]

just done a bit more tweaking and it seems to be holding, i think ive sorted it, now to crash it and start all over again.

Make sure that in rate mode the pitch slider is in the middle of it's range with the blades in line if you fold them towards each other

[loz]

yeh i thought id done all that but it still kept spinning, in the end i just kept adjusting ball joint til it stopped then switched to hh and was sorted, slider still looks central so must have been me as it was obviously slightly off, anyway been and had a go since then just looking at the crash damage now!! luckily just a cheap set of main blades

if its pulling to one side always always do it macaniicly never ever use trim on the tail servo

[loz]

yeh thats what i been concentrating on, doing everything mechanically, all my trims are central

[smokingtommy]

how much gain do u have

[loz]

gain is 70%

[smokingtommy]

wow omg 70% , ok , take of the link fron the servo to the tail . next step senter the servo by setting the TX to 0 trim ,now find a servo arm that will allmost be at a 90 degee
you know what take a look here
