TRAINER FUEL & glow plugs
Got hit with more snow [:'(][:@], about 6 inches, last two days and still coming down as I type [
] so learning to fly is delayed for another week or two until weather permits. And I am getting a *@#+%&^ cold now [sm=angry.gif]
I am getting prepared to purchase my fuel and I have a few questions?
1) From what I read here at RCU and other RC sites is that the best fuel for trainers is between 10-15%. What exactly is the % mixture consist of? Would that be something like 85-90% Nitro and 10-15% oil or ???
2) I was at my LHS yesterday and all he had was 15% in stock. Is that OK to start right off with or (with me never flying before) should I start with a lower percentage?
3) Is there a particular brand that is better than any other? What brands do you guys like?
GLOW PLUGS:
1) What is best that will work in all trainers?
2) Where is the best place to buy in bulk?
3) How is the best way to store them in a field box?

RE: TRAINER FUEL
It means you have 15% nitro methane and the rest is METHANOL and oil. I wish everyone would stop using the term NITRO as a name for glow fuel. This question proves how misleading the term can be!!! The fuel from your hobby shop will be fine.

GLOW PLUGS:

there is no best for all trainers, glow plugs are engine dependent, some engines require a long plug some a short, some a turbo, and then compression and nitro percentage play a key part in how hot or cold the plug needs to be.
2) Where is the best place to buy in bulk?
most LHS give a discount if you buy the full sheet, at least every one I've shopped in does.
3) How is the best way to store them in a field box?
in their original packaging.

RE: TRAINER FUEL & glow plugs
Is this something I can use in all my trainers?
http://www2.towerhobbies.com/cgi-bin...&I=LXJA89&P=ML
Or should I use something like these?
http://www2.towerhobbies.com/cgi-bin...&I=LXCB26&P=ML
And what is the “hot�
Both say they “Work on All 2-Stroke Enginesâ€
My engines (.25, .40, .46 & .32) are all 2-stroke and use short glow plugs.
Or should I get glow plugs specifically designed based on each of my individual engines?

Tower brand plugs have a bad reputation.
OS #8 plugs will probably be fine in your engines

RE: TRAINER FUEL & glow plugs
Two or three spare plugs are all you need. If you blow 2 plugs in a row it is often a sign of a faulty engine possibly a peeling liner.
Get fuel with 2% to 3% castor oil and the balance synthetic oil if you can. !0% nitro will do fine 15% OK any more is too much.
Tell the model shop owner the engine you have and he should keep you right.

Yes, It is possible I am mistaking. SORRY 
.25 and over traditionally take long?, still learning

You sure about needing short plugs? Usually you only use short plugs in engines that are .10 and under.

RE: TRAINER FUEL & glow plugs
Get a Fox Idle Bar plug if you use an engine witha long plug (OS 46FX and the like) I switched from the OS 8 plug to these and so far I havn't had any trouble at all! As a matter of fact, the engine runs a little better!. Then again, I replaced both of my 46FX's pistons & liners with Chrome ones from Magnum (pretty much a direct fit) and they work great! Good Luck!

1st of all we can recommend all the fuel in the world to use however the best thing to do is take a look at the engine recommendations.
2nd for the glow plugs. You get what you pay for. I have tried a few different kind and I personally like the OS8s. I test a few different kind and also the majority of the guys at my airfield use them and love them. I found them on Tower Hobbies in bulk and are priced reasonable. When it comes to storing them get a little box like what is used to seperate nuts and bolts and etc. The craft stores have them for about $2. I leave mine in the package and put them right in the box. they are in small packages and fit great and then you don't have to worry about the wire getting damaged.
those are my thoughts.

RE: TRAINER FUEL & glow plugs
The other thing to do is to check the instructions that came with your engines to find out the proper heat range of the plug that each engine needs. You'll be happier if you do this, rather than just assuming that they all use the same type of plug.
