Hi, set up servos with pitch curve, 0 25 50 75 100, the throttle curve does not matter.

with the throttle stick at 50% all the servos should be horizontal (level). they all go up at high stick and all down at low stick.

hallo Garry! is that ok when ol of my servos in SA looks down in low stick. not horizontal??

[GaryGraham66]

Hi they will only be horizontal at mid stick (50%) and then only with a linear pitch curve.

SA ?

Not an expert but the best place for a 'tail'-servo is on the left !! This is to minimize damage from rotorblades chopping up the servo....in case of a crash.

Thanks for another great video. Type of servo used?

[GaryGraham66]

Hi, thanks for the comments, the servo is a Futaba s9650, quite a popular servo for the tail and works well with the GY401 gyro.

How did you secure the plastic control rod guides? the ones on my 450se are a bit loose on the tail boom. Did you use super glue?

Hi, use a tiewrap (cable tie) and slid it under the guide at the top, cut off the excess either side and you're good to go (c:
