Sheerline trafaglar sub
« on: July 30, 2017, 09:24:33 PM »

Helloooo all,


Complete newbie here both to forum and rc subs, had cars up to now, kind of wish I stuck with them now , seem to have a problem with the sub as in it don't dive at all, could be me as I ain't to sure on how to dive it, followed what I got told by the person I bought it off, there is a knob top right of controller turn it one way is dive other is up ( this is clearly marked on the controller) however nothing happens, just sits there like a lemon ! Personally I don't think the pump is running, is there a certain procedure I have to follow when diving her?battery is fully charged ( charged with a smart charger ) also put air in the tank ( two pumps of a normal bike pump )


Please help !

Hi


Sorry that I can not help out with the problem that you are having with your boat but the Association of Model Submariners do have a Facebook page, some one on there may be able to help.

That's all right, Mr Ryan. My Morse is so rusty, I could be sending him dimensions on Playmate of the Month.

Hi,

Do you know whether it is a Dynamic or static diver, dynamic requires forward motion and ballast to drive the sub down a static will flood ballast and submerge without forward motion.

A Sheerline I believe was the latter, is your rudder working?, can you hear the pump running inside, possible airlock, can you post a picture.

I'm sure Andy will be along soon. It is probably something very simple.
Some checks to make
Are all the tx and rx batteries full charged. Ie not charged for 1 hour.
When you turn on do the rudder and elevator planes work. Also the throttle?
As it's the dive knob....can you here a pump switch on and hear it working
Post answers to all the above to start and if possible pictures.
Will also need to know what type of radio....ie futaba, hitec  etc. What mhz. 27   Or 40.
Also, I take it the WTC is clear. Is there and water or condensation in it?

Hi ,


Thanks to all your replies above 😊,


Batteries as far as I am aware are fully charged, the controller was left on charge for at least 10 hours , the sub has NIMH battery fitted to which i csrried out a full cycle on ( discharge then recharge via my charger) its a 4500mah I had my charger charging at 1 amp so only slowly charged her.


The rudder, all flaps both front and rear work , as does the throttle.


When I put it into dive mode the front planes move into the correct position but I can't hear the motor running  both in and out of the water. 


It's a Futaba controller and I believe 40 MHz, will confirm when I get home.


I presume WTC is the water tight canister? If so that's all clear no water / condensation.


I will take some pictures when I get home.


Thanks for all your help , hopefully will get her sorted.


Cheers

Will the pump run when not in water ? To me the pump looks like a normal 12.v washer pump on car, so I could check to see if I am getting 12 v to the pump when I put her into dive mode

would be helpful.  It should be a self priming pump so I assume it will run in and out of the water.

On the one I had the pump was controlled by a servo, the servo horn pressing on one of two microswitches depending on which direction you wanted to pump. I assume this is the same. Can you see or hear the servo moving? If not you may have a duff servo or a loose connection. If you can, is the servo horn contacting the microswitches? Either way I think taking the WTC apart is the only way to be sure.

Please help !
Link   The second picture down in that link shows an actual Sheerline dive cylinder.
Bottom servo (S3001) controls the dive planes via pushrod  Top servo (FP-S148) hits the pinch valve and dive pump microswitch.
You don't want a change in buoyancy when moving the planes by the top right rotary control. As in the photo, they should be on separate transmitter functions.


Klunk wants to know if you have a Sheerline  dive cylinder in black pvc or a clear (transparent) one with enough (minimum five) separate transmitter functions hooked up to receiver correctly. Then, if you have a failsafe, just like bikerdude999, make sure it isn't inhibiting servo movement. That is the bare minimum info that any submarine facebook noticeboard users needs to know as well.
