Pls help save my Viper

[PCC]

Hi - I have got an old Kyosho Viper which I like very much.... I was trying out the balance on a new boat and put the Viper in my fish tank to see what is the flotation angle as a reference point.... then realised that the tubing where the shaft runs is leaking water in real quick. Is there anything I can do other than greasing since I have just greased it before my last run and it is leaking now? Any coating that can be done on the tubing of the shaft (which can be bought in SG) to save my poor Viper??

Thanx

Hi Ching Chong,

The tube the shaft runs in - is known as stuffing box, u need to check a few things. between the stuffing box and the shaft coupling - how much space u got there? Is the shaft end of the coupling above your waterline? If it is, put a short length of silicone tubing to extend the stuffing box to the coupling.

Check your bushing/bearing at the prop end of the stuffing box, if it is worn replace it.

Hope it helps.

Bring it tomorrow afternoon to PP, I will be there, can help u to trouble-shoot.

Thanx James....

I have got about an inch between the stuffing box and the shaft coupling. I will find a fish air tube to see if it fits - but dunno if there will be a lot of bind. This boat is quite old and there is no bushing / bearing at both ends of the stuffing box.

Yesterday I pulled out everything in the Viper to rearrange things - see if I can set it back in time tomo. But good that you are going to PP - will go there anyway to see ur boats run..... (my new small boat is also done so also want to see if it floats/moves - maybe need your help to troubleshoot that one if it doesnt work right)....

See u there.

Any pic of your new boat?

Took this shot..... I traced back the package.... its from a shop called Astec. (sorry posted this to the wrong thread with wrong photo earlier - can anyone teach me how to remove that post?).

That boat is call Raptor? If it is, befitting this forum, many Trexxes, Raptors around... maybe this is the wrong forum !

OK - I rename it when it is back alive again.....

the thread is very apt - my Viper needs saving in another part. Needed to change the burnt motor and wanted to remove the coupling to put in a tubing..... but the grub screws are too tight and both are rounded. I hammered off the motor but cannot hammer off the coupling from the shaft. Tried heat, hammer and supergluing a allen key in - all in vain. Must be a bad boat week..... Save them please~???

Drill out the grub with a smaller dia. drill bit.

thanx James - will try that.... must I drill to the diameter of the ID of the coupler or something smaller just to weaken the grub screw structure?
