hey... i just decided to make my first cannon a few days ago... and i thought a bbq iginiton would be cool... but i cant really get the dam thing to spark big enough to make this 20% nitro crap i have go off... im not to sure if its supposed to be a reallly big blue line but mine looks more like a white "piece of hair"{... bout 3/4 of a cm long...

so i would appreciate if you guys could help me wiht this problem... if this is a retarted post u can go ahead and get rid of it, but i would appreciate the help -- Thanks

Your not going to get it more than 3/8 of an inch and usually it's whitish bluish purplish; that might be the best gap you can get.

What is this 20% nitro crap you are trying to ignite? This is most probably the problem.

A spark gap from a piezoelectric BBQ igniter should be no more than about ~1/8" to work good. Small gaps work great for me.

that nitro junk is for little 1/8 scale r/c cars... they go about 60 mph...
its pretty.... pretty flamable stuff

but i guess ill shop around for somthing that might work better

thx for the posts

hey... sumthin else... im useing a one inch screw to make the connection... i was wonderin if thers somthing else i could use thats more reliable... or just a better over all conducter cuz it only works about 1 out of every 15 clicks

The nitro fuel dosn't work i have tried it. use starter fluid from a auto storeand remember you need very very little or it wont ignite

Or you can use hairspray or the Right Guard generic crap.

BTW, this is being moved to General Spud Discussion, as it has nothing to do with How-To's.

The R/C car nitro fuel works just great. All you have to do is put a cap full of it into the chamber then roll your cannon horizontally to coat the chamber with the fuel. It actually works very well and gives off a huge blue flame.
