Hi I have a hong Nor X1x CRT and it has developed a mind of it's own. I have new batteries in Rx & Tx and have used it in numerous locations but whether the engine is running or not the steering and throttle servos twitch all the time making it almost impossible to control.
I have checked everything but don't understand
Why I am getting what appears to be really bad glitches / interference running the standard Futaba radio system

Has anyone got any ideas it's driving me mad



May thanks

Da

what is it 27 mhz might need new crystls you made sure they in properly chech for breacks in the arial

Hi MTC, Yes its 27Mhz
I have checked both aerials for any breakages, both the crystal in the TX and RX are both fine and in place securely.

I have never had this problem with any other remote control model that I have owned.

The model is only one month or so old, I just do not understand whats going on its making it impossible to tune as the throttle goes up and down on its own.

Could it be the cheapy servos that come with it? but then it never did this a few weeks ago

Any ideas welcome.

Many Thanks

David

could be a faulty reciver you got any others you can test

Could be a faulty transmitter, reciever, servo, or just a wiring problem. if you have any other cars or anything just switch parts around to eliminate anything, thats the only thing i can suggest, otherwise take it to a shop and get them to do that exact same job with it :-P

Good luck fixing it man! :-) B)

is it still happening now, that you are in a different place! Hmmmm thinking of some kind of interference where you were ?

otherwise it will be a matter of process of ilimination i fear.... have you checked to make sure you have no moisture in the reciever. even condensation on the PCB can cause problems....have a good look.

Hi Guys thanks for your advice, I have taken out all the electrics given them a good clean and replaced them all.

Now it seems fine, I only use 2.4Ghz in my Helicopters so dont have anything that I can swap with it, I was wondering if I get it again if its worth changing the cheapo standard servos with some better ones either JR or Hitec I did see some HD Power servos that were only £20 with 17Kg of torque anybody used them they look a good spec as my current steering servo is only 6Kg of torque and the throttle servo just a Futaba S3002 or something only £7.99 I thought normally with the the throttle you dont need a great servo but as it acts as the braking system aswell it need to push quite hard to get decent braking so maybe upgrad
e that too?

is that worth doing or will it not make much difference, i dont know much about Rc cars just making it up as I go along.

Many Thanks

David

:lol: i like this bit.. lol

Cool glad to hear, its working ok again at the moment, bit weired though that a clean sorted it, maybe it was all down to dirt and or a loose connection..

As a back-up mate i would think about buying another receiver, it dont have to be nothing great, just one that you can keep for a spare and a tester, £10 one would do nicely..

As for the servos, a 17kg for 20 quid a a pretty good price, ive not heard of them but could be worth trying, chances are as modelsport sell them, they cant be bad. a better steering servo would help a bit with handling, more so when off-roading. you need to find one with a good mix of high-torque and high-speed turning.

And your right with the throttle servo, mostly you dont need one as powerful as the steering servo, all models come like this, but there no harm in putting a better one in, it can only improve things really :)

If your breaks are too loose?, you should be able to adjust the brakes from your chassis mate,



If you un-do the stopper on the end of the servo rod, if you push it close to the brake arm rod loop, and do it back up again, it will them make your brakes tighter, do it the opposite way to lossen your brakes..

Hope this helps a bit. :thumbs_up:

HAPPY RC-ING :rc_car:

If you want to upgrade your servo's for better steering & brakes.
I would use your existing steering servo on throttle brake.
hong Nor use rebranded Futaba servos (I think its a 3305 Futaba on steering)
And use something like an Ace 1015 on the steering.

Hi Thanks Colin & Mark swapping the servos is a good idea.

Mark I tried moving the collar on the servo rod in but when you apply barkes on the Tx the servo arm doesnt move much as it is, so in neutral throttle position I have the collar just touching the braking arm so the slightest movement applies them but as I said as the servo moves so little the braking isnt great :-(

Marc , you can adjust from there, but they should be set to length so as not to hit the tank, You should then adjust from the knurled adjuster stop on the out side ends. :thumbs_up: :thumbs_up:

Arh cheers ian :thumbs_up: see even im still learning, that never stops lol..
