Yes, i have not used theese many glowplugs in years, combined... The old one in gold would last a gallon, now sometimes it is two tanks and its dead. Mye engines are healthy and so is the fuel. I had a coupple of old ones in gold pack, and they last.

Use 97T's all the time in my BTT. Work great!

tip: if you are trying to use a plug for a gallon you are seriously jeopardizing your engines internals (its not a "my plug lasted 2 gallons" contest) , plug filaments get very brittle , they are designed to, so as they heat up to pretty high temps and are subjected to high pressures being part of the combustion chamber . i would highly recommend utilizing cool plugs no more than half gallon and hot plugs no more than 1/4 gallon of fuel , leaving hsn just a touch on the rich side will keep plug cooler as noted by the "wet" plug when inspected .you will notice the tune fluctuating , sign plug needs to be replaced for optimal performance
i have personally not have had any problems with the c6tgc as of late but dont really recommend 97t except for break in plug as they are very very brittle , large air orifice and thin element provide for easy tuning but plugs dont last long at all , i would personally change 97t plugs about every 6-8 tanks of fuel (no joke) take my advice for what its worth , its up to you , i am not really trying to sell anybody plugs as some have mentioned before but more so offering the advice based off of knowledge from what i have seen from customers engines and have personal experience with |

I change my c6 plugs on average every other race day or 3 times a gallon. Never a flame out in over 7 gallons. Knock on wood. |
Monty. Thanks for the info on hot plugs!!!!
Without knowing this, I have been doing what you recommend (shit ass luck lol!). I put a new plug in for practice - say about 30 minutes - roughly 500cc approx 1/8 gallon. New plug in for racing, 3 - 7 minute quals and 1 - 30 min main - roughly 60 minutes run time. 7 - 8 tank fulls - approx 1/4 gallon. Bill |
Damn I guess I need to start doing this also. I've been trying to win the plug life contest! Guess its time to stock my box with glow plugs..:eek: CHA-CHING!

Regarding the 97t plug, I guess u get Wat u pay for. Getting more plugs cheaper, but then replacing them more often isn't really achieving anything more or less. I'm jut finding out as much info on the novas as possible for a friend that I'm helping out get setup for his first nitro 1/8 buggy. I'm very interested to see how this engine goes once we hit the track :)
Will still probably go the O'Donnell plug and replace it every morning before a new days racing at a minimum. Thanks a lot for everyones advice and tips, I've found this thread very helpful :) |

Another piece of plug knowledge. Do NOT use a brand new plug for a main. You want to put at least one good heat cycle on a plug before subjecting it to the abuse of a long main. I like to put a new plug in and run a few laps on it in practice. Just half a tank to a full tank. Pull it out, check it to make sure it still glows and isn't damaged, then save it for future use. Now you know it's a good plug and have toughened it up a bit for the main.

A few quick questions please:
1) A steel flywheel has what advantages in what circumstances? 2) An aluminium flywheel has what advantages in what circumstances? I have stock, aluminum flywheels for my Team Associated cars. I run the Novarossi BONITO.21-7XLB 7 Port .21 in my RC8T. I run a Novarossi PLUS.21-4BTTA TUNED 4 Port .21 in my RC8.2 3) Is there a steel version flywheel comparable to the Team Associated Flywheel, Hard Anodized Aluminum (RC8) [ASC89136]? If you could answer and link, that would be great. Thanks in advance. |

Ok thanks a lot.
That is great run time! Would this pipe/manifold fit the mp9 ok? NVR51020-21 |
So I am looking into a Keep OFF 4 Port or a 4 BTT. What kind of runtime are you guys averaging in each motor? Which pipe and header work best? My main goal is to get consistant fuel mileage. Which should I go with?

Rest of you on this forum do this? |
I have a big assortment of plugs - NR, Picco, OS, and Odonnell. And the OD's easily last as long as anything else, if not longer. If any of them are suspect in terms of longevity, it's OS.
It's just an error to assume that because they are cheaper, they are not as good. (Same applies to engines of course....................................) |
