WillyChang 1814 Posted December 24, 2013 these are all diesel principle (=compression ignition) engines, vs electric spark ignition Enya SS25 should use a glowplug for starting. Depending on the head cooling arrangement, your engine will have short fins for airplane or a watercooled jacket for boat. Car will need taller finned head for less airflow than plane. Cars use an airfilter (usually paper or sponge element) to keep out fine dirt, good idea but its all a matter of how long you like your engine to survive. Sponge soaked in sticky dirtbike airfilter oil works very well. Share this post Link to post Share on other sites
lou5590 1 Posted January 30, 2014 So what fuel do I use? It was from a Rc airplane that I bought second hand, unfortunately the body was beyond repair but the engine ect was sound. I was thinking of turning it into some sort of boat, slow moving(I.e not speed boat more like cruise liner or aircraft carrier replica). Share this post Link to post Share on other sites
WillyChang 1814 Posted January 30, 2014 Nitro engines use nitro model engine fuel, any decent hobby shop should sell it. The fuel is usually a mixture of 15-20% castor oil & remainder is methanol. Often some nitromethane is added like 10-25% in lieu of some methanol; this is why it's called "nitro". Nitro can help better idling & more power. But it's also expensive, dangerous & not easy to source for homebrew. How do you know the engine is "good" btw? Hard to tell until you've heard it running.

lou5590 1 Posted January 30, 2014 The guy I bought it off had it running before I bought it (sadly he's passed away now so I can't ask him) he topped up the fuel tank with some clear liquid out of a drinks bottle hense didn't know what the engine ran on Share this post Link to post Share on other sites
WillyChang 1814 Posted February 7, 2014 you do know about needing to powerup the glowplug before it'll start, right? Share this post Link to post Share on other sites
