I just got a new DLE55 from PEAK MODELS along with their PITTS PYTHON ARF. Both seem to be excellent. My question is has anyone bought replacement spark plugs for these engine? I emailed "WAY", the contact person for PEAK Models and he instructed me to get an NGK brand CMR6A plug for it. I did, and it is the correct threads for the engine, but the tip of the plug where the shielded ignition cap goes on will not fit. The NGK plugs are like a regular car or weed eater type plug end and the shielded plug cap that came with the DLE 55 ignition is a different type for a different style plug end. Anyone got any ideas? Thanks in advance..PACO

They told you to get the wrong plug. They had you get the resistor plug and you don't need that type of plug for the rcexl ignition. What they should have told you to get was the NGK CM6 plug.

OK, thanks, I'll go get a couple more plugs, this time the correct ones.

gr8taz steered you right.  The CM6 is also much better and will last longer than the factory plug that comes with the DL's.

Ive been using the original plug for months now doing extreme 3D, and hadnt had a single problem. But a brand name would last a little longer.

Maybe some of the stock ones are good and some are bad. Quality control thing. One thing for sure is that a CM-6 is a good idea to put in there if you do extreme 3D. Wouldn't want a flame out 10 feet off the ground in a hover.

A spark plug should last for a 100 hours fo flying or more.  Makes sense to stock up on a bunch....

Just as a note, the plug that came with my DL50 had the insulator so off center the porcelain was almost touching on one side of the shell.  Needless to say QC didn't catch that one.

A NGK CM-6 plug has "NGK" imprinted on it as well as CM-6.

The ones that just have a CM-6 on them are not NGK's

I just recently purchased an Extreme flight yak 88'' w/ a DLE -55
Ive heard to get the CM6 sparkplug And plan on grabbing a few.

Ive never dealt with a gas engine before at all. However when breaking in nitro engines i usally ditch the plug after a break in
My question is would people suggest me using the stock plug for break in time then replace?
One big difference "I know" is you break in your engine in the air pretty much on a gas engine..
Any suggestions will be appreciated!

I wouldn't trust the DLE plug in the air. It is reasonably safe to use it on the ground.

Junk the stock DLE/3 plug ang get some NGK/CM-6 plugs.

Honda number is 98052-56471, it's an NGK CM-6 in a Honda box.
At the auto supply store it's (NGK/CM-6) listed as a Stock #5812

The other big difference is you dont break in a gas engine blubbering rich.

Take the stock plug and smash it with a hammer.

....or give it to someone you don't like.

I second that, these are good plugs and, last time I checked, cheaper.

Been wanting to ask: what's a heli moderator doing in the gas engine forum?

Where in Jax? I lived in Julington Creek for almost 20 years; flew at Gateway, a truly awesome flying site especially when comparing to ANYTHING in Jersey. I miss it

BTW- I have nearly 100 flights on the stock DLE plug and haven't seen any problem at all; about 25 hours of run time. However I always carry the NGK JIC

I moderate the heli forums but I fly a little of everything. Gliders, gassers, helis, electric, nitro and gas.

This stuff is mine and the Pawnee is the latest review project that should be going live in the magazine section soon...

I fly out at Jax RC but I belonged to Gateway for a while and lived in Fruit Cove.

You can even see the mountains of Florida in the background?

Eh....sorta.....those are land fill mounds

The biggest mountian I know of in Florida is Space Mountian. You can watch your dog run away for hours from the porch steps.

15 miles west of me there are some hills like that. They are the Crawford County Land Fill.
