differnce in motors

whats the differnce in nitro and gas engins
from what i understand
nitro is more intense and includes oil lubricant in it where as gas works like a regular compustable engine

They use a different fuel, and the ignition is different.

A nitro engine works in a similar way to a diesel engine - lots of compression, but it uses a glow plug to ignite the mixture. The fuel and oil are mixed together, and both come in through the carbourettor (because the lubrication is a 'total loss' system - that blue smoke trail from the engine is oil being burned)

The fuel is mainly methanol (yes, the same stuff top fuel dragsters use), then there is some oil, and finally the nitromethane, which is used as a power additive, and it helps to make the engine throttle better.

Gas engines are the same as you would find in a strimmer (or weed wacker, as they say in the states). Thy burn petrol, and the oil also goes in with the fuel (but only around 2% compared with the 15-20% oil that nitro fuel contains). The mixture is ignited using a spark plug.

GOOD INFO... thanks man

Engines thread,, Guess this is the right place to give a heads up on a new elect motor called the AON 3500 brushless.
POS, Chunk-O-Miada, Pile of Silicon BILE

I got an almost new one from my buddy that whent to gas and gave up his trex all metal electrics for it, he had a problem with this motor after one flight, A shreeking sound at spool up and no power to fly.

Come to find out the Magnet [Neodium] that is wrapped around the drive shaft of the motor is held on by Glue .
And of course it separates when it hits 200 degrees. Go to AON's forum on the websight and you will find this is a plaque with these engines, I am glad I got it for 0 dollars but still wouldn't trust it on my x400 blinged out at 100 feet , I reglued the magnet hole where the shaft goes through but this problem needs a whole new design, I am going to see if my neighbors machine shop can't drill a hole and apply a grub screw or something, Glue can't possable handle the heat and abuse at the main sorce of power.
This motor runs hot, powerfull and efficiantly as well , darn shame this defect in engineering because it works great with govenor mode as well, it's a powerfull 2 pole motor. At 80 bucks incl. shipping it's a waist of money till they admit a flaw rather then hosting a shaft rebuild kit on their websight for 14.99 they should be anouncing a recall and a perminent fix for this kind of dough.
