answer lies at autozone. there are a couple ways you can do it....

1. J B Weld.... its alittle messy but it will stick to plastic and wont erode away from the nitro

2. they sell a two part epoxy, it looks like a suringe(spell) needle more or less. it has a glue and hardener all in one tube you just squeeze it out and apply.

both will work for how long... depends on your driving. there are a couple other ways i cant remember i used to work at autozone and had people ask about it. i advertised my r/c cars there. but go to an autozone or auto parts store and ask them for something that will bond to plastic and not erode away from fuel. those two should do the trick

good luck

air leaks are nothing to play around with,, i would contact the manufacturer if you bought it new that way.. somehow getting a new tank would be the best option.


with this being on the seam you might be able to melt it back together using your soldeing iron though,, it would at least buy time to get another one. make sure it is clean of fuel and oil before you work on it. denatured alcohol works good for this

My recommendation would be to buy a new tank. I have been down the 2 part epoxy road and just havent had much luck. Once the tank gets fuel or wd40 or any lubricant its is damn near impossible to get clean enough to hold epoxy well.

However if you need it to race and can't get another in time, then I would try it. Make sure you clean the heck out of it and try to rough up the area the epoxy will sit. If you engine acts funny after doing this, you could still have an air leak. Try at your own risk.

FYI....Jb Weld is NOT fuel proof....it willl seal up temoparily...but will Soak up nitro over time and eventually fall off.....i used it to seal up a pipe to only have it soak up some exhaust nitro and fall off....your best bet would be to get a new tank and be done with it.....but if u Wanted to...Three bond 1211 Would do the trick..its what i use on all my losi tanks on the fuel line and works like a charm.

Heres is a little tip, that I use. Take a wide tip flat screwdriver. Heat it up, with a small torch, and with the hot screwdriver lightly rub it along the edge of the tank where the top and bottom meet. It will melt the top to the bottom. ( you will have to continuely heat the screwdriver,but this way it will keep you from melting to far into the tank ) But still becareful not to go to deep. Hope this helps.(note I do this to all new tanks,and have never had an issue)

Yea just buy a new one, it isnt worth having a hack job fix go bad on you in the middle or your race, or even just your day at the track. Maybe use one of the methods mentioned above on the old tank to have as a back up in an emergency but dont make it your main tank.
