Fuel-Proof Glue?
 

I had to glue a hole in my plastic crank-case cover. I used CA glue, do you think that it will hold up?

Do you mean the backplate?

RE: Fuel-Proof Glue?
 

If it is the backplate, and I think it is because I can't imagine anything else being made of "plastic", well, I would remove it, thoroughly clean it in something like rubbing alcohol, let it dry completely, then apply epoxy to the area in question. Not much, just enough to do the job. Let it cure overnight and then put it together. I would also test run the engine on a bench to make sure it's ok.

NOPE!

This was a hole drilled for a smoke system and after a crash was striped out.  After crash it was C A glued and now I am installing this LA 65 In a Supersporster. What should I do???

RE: Fuel-Proof Glue?
 

Agreed, it's unlikely it will hold up.

Follow CGRetired's directions above to fix the hole.

Thank you , Ken.

Glue wont do. A short screw as a plug?

Order a new part!! http://www.rcuniverse.com/forum/js/f...ular_smile.gif

You can order a new one here for $8.99:

CGR's suggestion won't work either - Epoxy doesn't stick well to plastic.

I would tap the hole and put a screw in it. make sure the screw doesn't go in too deep and interfere with the "moving bits" as the Brits would say.

RE: Fuel-Proof Glue?
 

The screw with some Gorilla glue on the threads may work but for the price just order a new back plate.

I went ahead reinstalled a threaded nipple, and installed the smoke system. The Supersporster 60  now weighs 8 Lbs.

RE: Fuel-Proof Glue?
 

I was wrong !    7 Lbs.

Drill a bigger hole retap and plug it

With a 4c engine this wouldn't be a huge issue as the case has nothing to do with the mixture. With a 2c engine you are playing with disaster to trust any glue on the plastic used in model engines. If the glue fails at anytime during flight you'll suffer a lean-out of the mixture and failure of the engine or a dead stick. Murphy's law says that this will happen at a critical time and you'll lose the plane.

Just get a new part and be done with it unless you are willing to put the entire plane at risk. For a $9.00 part I sure wouldn't risk a $200.00+ plane and associated components. Not so sure I would trust a threaded nipple or plug into the plastic either.

Its a high mileage La 65  .  It Is fixed .  Without Glue.  Thanks everyone!!

Even when we are wrong.. [X(] ;) we aim to please.
