the od plug is tapered like a novarossi plug, they wont work in the grp, but once you ruin your head button send me a pm i have a brand new turbo button i can sell you with a grp plug

.


Word up! That's what I remember, no wonder the damn thing would leak with a P3 after suffing a OD in there.....

I have a gently used button on ebay right now, P3 run from day 1.

yeh i here ya on that ...how do you explain the several people on this thread that have used an o.d. plug before using an o.s. plug and had good results ...? just curious not meaning to aggitate ...im just thinking by the looks of it ...you best be sure which plug you wanna run ...because you may be limited .....if it pisses fuel with an o.d. plug then im gonna have an assload of odonells plugs to unload ...one things for sure the results will be posted this weekend .....

just keep in mind i have the button on ebay for ya to bid on

good luck with the OD, let us know how it works.

i dont know which page it is on, but someone a while back actually measured out all the different plugs, the only one that matched the grp plugs were the os plugs, i havent had a issue with a p3 i change mine out around a gallon of fuel, havent had one go out on me during a race, if you run the grp plugs make sure you run the 4 the engine acts a little finiky with colder plugs

yeh several peolpe had good luck with them ....(o.d. plugs)...on your bottom end i read through where you had issues with it ...i mean there are also several people who said they had really good results running the .21 in truggy...but hell i might blow my motor up,not make a jump , get pulled out of the corners ....you never know ....... we shall see .......

yeh mine came with a 4 ...i just dont even trust it after i helped break my buddies in ...and the grp plug wouldnt lite out of the box new ............yeh on the measurments ...the guy who did it only used o.s. and grp plugs ....no other plugs were measured ....so i mean really the other brands havent been measured by a mititoyu drop gauge ....not that they need to ....just saying .....

can you tell me the exact ignitor that you used? i have raced mr ninjas for around 2 years and i thought that i had a bad plug, but my ignitor wasn't strong enough. i use a hot shot2, burns really hot and works great on mr plugs. seriously, i thought i had a bad one out of the package. i changed the battery in my ignitor to a brand new d cell and it still wouldn't glow, tried a friends hot shot and bingo, it wasn't bad after all.

does anyone know whats a good temp the .28 would run at?
i like to tune to smoke and power but i just want a estimated temp to look for



im only on my second tank and it looks promising

i have been using the same hobbico w/meter for 2 years ....i think its taking a dump right now ....i got a long reach patriot rc brand ...it came with an 1800 mah battery ...but i will run a maxamps 4.4k 4400 in it ..thats what i ran in my other one and it will last months without charging .....the racers edge is nice and for that matter i was gonna get a long reach hotshot2 but it was like 7 bucks more than the one i got ..... sometimes the contact in the head gets out of wack ...my buddy put a piece of heat shrink on the inside of my old one to straighten it out and it worked like a champ for a long time .....just get a decent nimh high cap battery for it ....best thing you can do for a glow ignitor ...put some juice to it ...inmho

ill take a look at the pipe. and i guess ill start runnin the os from the start. i have like 20 p3 in my rc box

i noticed the grp plugs take alot of voltage to fire up also, the os fires up even if the glow ignitor is getting low, wasnt cool when i would go to start my car for the main and the engine wouldnt fire up, had to look around for different glow ignitors to see who had enough juice left in theres to fire it up

for anyone wanting to put the glow plug question to rest ...it is rested ...the odonells plugs work perfectly in the grp motor ...no problems at all....put 3 tanks on it today to get started breakin it in ....after dumping the way overpriced and non working out of the box grp plug it was smooth sailing ...the motor stayed at 217 degrees for most of all 3 tanks ....never missed a lick ...my buddy over at my house even said ...my god will that motor ever quit idling .....will probably get the rest of it done tomarrow ....will post on how it goes ....i should be putting some video of it up on youtube tomarrow night ....

What is the suggested needle settings on a the tuned motor, and what comes from the box?
