YS 56 Eats Plugs

Just got my N5C together, the YS 56 is used... and the first few tanks I had no problems... after figuring out my needles were way off, and resetting them it flew great..... once I land and refuel after short cool down it would not start again.... pulled plug... put new one in fires right up?!?!?!?!? its done this three times now and I finally inspected a plug and saw the coil looks to be pushed to one side... there are no shavings in it... Do I need to put in a head shim? am I to lean? using 30% nitro os #8 plug 100* outside...

In most cases, I say you are lean but; if it is a used engine, more discovery is in order.- check bearing and piston ring, if they feel/look good, then for sure you are lean.

My 2 cents.

Yeah I just checked my needle settings and the high was at 1 turn even... mid was at like 1.5 Ima gonna say it was way to lean I hope thats the problem will see tomorrow!

Finally realized the long needle is the mid not high like OS oops

on a side note it felt like it had WAY to much power...... I knew it was to good to be true ....

I had the same problem. I solved it by going to a Enya #5 plug and using two washers on it, and getting my needles adjusted properly. Runs great with lots of power.

we all, when coming from OS, had the same confusion with the needdles, you are not alone !

The right plug is fundamental as well;
depending on you flying field out side temperature.

At sea level/tropical weather OS A8 works very well; when I fly on mountain flieds / cold weather, I use enya 3.

I bought some OS A7 plugs, which is a hotter plug similar to enya 3 but I have not tried as yet, next winter will !

I do not know how is Indiana`s weather so, I can not give you an opinion but; try different plugs and come to a cocnlusion.

I hope this helps.

Make sure you don't have any bearing noise. If the bearings are going they will destroy the filliment in the glowplug. Catch it before the bearing lets loose or it can be costly to R&R the motor. Don't ask me how I know

The problem was just a tad to lean plus its 100+ outside... Made it rich and flew 5-6 tanks no problems and running great! thanks guys

I had the same issue and I had a bad gallon of fuel. The fuel had to much moisture in it. I would go thru plug two to three and weekend.
Do you see and greasey residue on the inside of your fuel tank?
