what glow fuel?

[GSXR~RACER]

can i know what type of fuel should i use for my trainer plane with old 46 engine. The person who installed for me uses 15%, but when i went to the shop, there are other types like 5%, 10%, etc. which is for what ah?? thanks.

5-15% are all ok.. just get someone experienced to tune the engine for you after you switch to the new fuel.

hmmm

hey bro y dont u bring to woodlands this sun and we'll tune for u. btw normally 15% with 18% synthetic mx is good enough. i think cool power is the most popular one used.

It actually depends very much on the engine design. 15% is pretty much for average sport engines unless the particular design is meant to run with it. My first RC engine, which is the ENYA .25 SS plain bearing runs very well on 5% nitro. I never subject my engines for more than 10% nitro unless they are called for. If you increase the nitromethane content even more, most engine manufacturers suggest you add gaskets between the cylinder head to reduce the compression ratio.

One of my friend blew the gasket and stripped one of the bolts securing the cylinder head of my 47 size engine I loaned him, after he ran it on 25% nitro. The engine ended up in the bin.

Read the instructions, if you have it.

Thansk so much everyone.. bought 15% coolpower..
hope this sunday can play.. really hope i can fly..

Huh?? Coolpower (green) is actually contains only synthetic oil which is more recommended for 4 stroke engines. Omega (pink) has castor/synthetic mix which is better for 2 stroke engines, especially ABC and ABN engines.

I usually keep a gallon of Omega (pink) 25% nitro for all my nitro marine engines and a gallon of Byron Premium Sport 5% nitro (also pink! ) for .40 and above airplane engines. Both fuels have a lube package that is a blend of synthetic and castor lubricants. For airplane engines less than .40 size, I simply mix the two fuels 1:1 to obtain a 15% nitro fuel... or with the help of a calculator, any nitro content between 5% and 25%. I also keep a bottle of Byron 100% castor oil "Lube Booster" (avail from NTC) to achieve the desired caster oil and overall lube content in any nitro fuel (very handy when breaking-in new engines ).

If you are running fully synthetic lube fuels, back off the high speed needle a few clicks from the peak rpm setting to prevent the engine running too lean in the air when the prop unloads. Otherwise, add some "Lube Booster" to your fuel... your engine will last longer

thanks.. learnt more things..

Two strokes or 4 strokes, its best to have a bit of castor mix. The Omega with a 70/30 syn castor mix is really good. It helps alot to prevent the bearings from getting rusty. An engine running on fully synthetic looks really clean on the outside, but inside will tell you a much different story.

Not to forget the necessary after run servicing......disconnect fuel line to engine, run any remaining fuel from the engine....apply after run oil (or any 2T oil) from the glow plug hole and carb opening....lastly, oil the front bearing and you will guarantee no rust
