I hear that sometimes glow plugs can increase proformence and make starting easier. I am currently running sidewinder 30%, what would be the best plug for this fuel and possibly if you know a link to them post that as well.

Thanks

OS LC3 or Mcoy # 59 are the 2 plugs I have found that work best....whatever you get just make sure it is a hot plug.

I use a medium to cold plug,

Everytime i use a hot plug, it doesn't tune well and the plugs blow quick, i've had very good luck with colder plugs on 30%

I thought the higher the nitro content of the fuel, the cooler of a plug you use. So 30% uses a cold plug whereas 10% nitro uses a hot plug, 20% medium. Is that not right?

That is correct.

So cold is the way to go?

slayerphonics

yes, medium to cold on a higher nitro.. cold plugs have a thicker element in them, seem to last longer for me too

l run medium mc-coy plugs there good, 2 dollars dearer on average , worth it l recon.30% is a very high nitro % to run, l would hope your in snow conditions for that sort of fuel, 20% is better and all these nitro engines are designed around 15% nitro content, they are not tested for advertising on 15%, thats probly a 30%ish mix but a nitro engine is designed for 15% nitro.Some companies even tell you this in there manuals, like kyosho, l would consider changing fuel, do you burn out glow plugs oftern on 30 % ?
If you have had good running/tuning and have run 30% all its life, and even broke the engine in on 30%, do not change it keep using it, but if its something newish, and you have just started using 30%, switch back ASAP.
Its not good for an engine to switch fuels, you should really use one % of fuel for the engines total life, or tuning can be come DOH DOH DOH !
Trying to squeeze power from a fuel % over a good tune is a very bad thing.20% will utterly rock tuned right, 25% is nutz, 30% is instant wheelies on trx 3.3, so lm wondering why you run 30% mix ? Racing maybe ? Or wheelie king ! LOL !
Yea cold plugs dude though l would try a medium first, if the temps are good, use medium, this will have the effect of less stalls when you pull up to idle, so medium if you can cold if its getting to hot.

Well, the bigger the engine the higher the nitro is recommended, so on a .28 i wouldn't run anything lower then 30%
I used to run 20% on an .18 engine but moved to 30% engine is sitting around 7 gallons or so still fine,

I guy was at the track trying to run his 3.3 on 10%... it was a joke,

IMO - go 30% you'll never look back

What is the best brand for a cold or medium plug, what is reliable?

I disagree....the size of the engine has nothing to do with the % of nitro you should run.....stick with 20% 12%caster oil.....higher nitro content will burn up your engine faster.....and on most engines the % of nitro content will be recommended by the Mfg. and if you want to run a higher content it usually involves running an extra shim or copper gasket between tthe cooling head and case.....I agree that most guys run 30% for competitive racing but they also get a new engine every 5 races or so...for bashing 20% is plenty....once you find a fuel/glowplug combo that works for you stick with it.

Well the guy who posted lives and florida, running conditions here are totally diffrent then canada,

So in florida you run a medium to cold plug on 30%

I'll leave it at that.

Ill agree on both points made here Im using an axial .28rr with 20% blue thunder and im using an os LC3 plug and it laster break-in +5 tank. so i will agree the OS plugs are great. Axial recommended that i use a cold plug when its warmer outside and hotter plug when its colder out. so i run by those rules and they seem to work well i can get 11 tanks out of OS LC3 hot plug and the axial iridium cold plug last about 7tanks
