Servo travel problem

[Reltub]

Hi guys i have a hirobo sceadu and think ive got a dodgy servo its got ds811 on cyclic, the aileron servo doesnt seem to move as far as the other 2 and when i go into monitor it confirms this do i need a new servo or can it e fixed?

Cheers

Just check your end points in your Tx to check they are at 100% on every setting. Also check you haven't got any Dual Rates setup anywhere as that could be the problem. What Tx are you using?

[Reltub]

Jr pcm9x2 the endpoints is travel adjust? In travel adjust they are all at 100 except for the elev and gear. No dual rates are used. I didnt set this up i bought it set up when i started flying an am just in the process o learning how to set them up etc etc.

Thanks

As this is your first setup start with a new model from fresh or wipe the one you're on now.

By this do you mean the monitor on the tx shows full travel from -100 to +100 on both elevator and aileron channels?

As a simple test you could swap the aileron servo with one of the others just to check. As a point of caution I don't think the JR DS811 servos are particularly very good for use in a model of that size. I found a post dated April 2009 saying then that the servos went out of production a couple of years previous to that so your servos could be very old. It wouldn't hurt to replace them now.

I would highly recommend starting from scratch with a new model memory on your Tx. You can never know what settings someone has put in, either intentionally or by mistake.

I also don't agree with the whole 'settings transfer' for pitch thing. That just cannot work in my eyes as every heli is different.

Start again with a fresh model and get someone local to you who knows their stuff to go through it with you that's the best way.

I think you have a point there with the age of the sevos are there any reasonably priced you recommend? I am going to wipe the memory and start again but want to sort wether the servo is faulty or not before i spend time re setting them all.
Regarding the monitor there is a thing in the tx that shows you how far your servos are moving when you put in stick commands.

Thanks alot

If in the monitoring screen on the Tx it also displays that it's not moving as far then it's not the servo, the monitor is the output from the Tx it doesn't translate directly to the servo movement. If you're only getting say 50% movement on the monitor then it's the tx that is causing this. Wipe it and start again. Which variant of Sceadu is it. There were 2 servo layouts from memory

No it is a monitor to show what the output to the RX is and the direction of travel. This is not an idication necessarily of how far the servo will travel.

At present for your model you will find it hard to beat a set of Align DS610 servos. They are a much, much better servo than your current JR ones.

If after starting again with a new model setup if you still don't get the servo travel expected just swap the servo for one of the others. It should only take a couple of minutes to swap them round in the model.

Ah that make sense to be honest ill wipe it and start again and let you know if not ill bang some 610's in it thanks again.
