Tutorial video showing how to start a new nitro engine for the very first time and break in procedures. I used a JBA .61 2 Stroke Nitro Engine in my Cessna 182 Skyline RC Plane.

It’s not just JBA O.S have great temp control but then again it’s kinda hard to get hot when high winds are constantly cunducting heat
@RcMasta90 that is strange. its probably was a faulty engine. no cranks shaft will break on first run if it was a bad engine or cracked shaft already.
hey i got a k&b sportster .20 and today i tried to break it in and started it and then it died after a while then i started back up and it was turrning over like butter and then died like a min l8er and then started up and i went behind the engine and setting it up and after a couple of sec the prop went flying off like 5 feet and when i went to go get it and the crank shat broke in half y did it do that? how i pervent from happening again? any1 have this happen to them? thx
looking forward to getting a engine then=]/
its not gonna be a thunderbolt with that engine…get a west 50v1 if u want speed..thats just a standard cheap engine mate.
@IFLY2deep4U Sure mate, I will keep 1 and 2 in mind from now on when braking in the engines for planes. For now, there is no chance far far away that i am getting a nitro plane again
I just have no time from these electrics awesome planes that are just coming in. I however have my eyes on a 100cc Pitts Bulldog though and I am thinking to go with twin cylinder 100cc engine 
but again, need to find out if i have enough time to do that.
ok sorry than forget no3, it sounds for me like a well tuned engine, as you gave it the gasstrokes at the end of the video.
Cool engine is good
But 1. and 2. can really do harm to a new Engine, I saw both.
@IFLY2deep4U Thanks for comment my man. different people got different ways to break in the engine. Engine was set to as rich as it can keep running smooth, and it was running totally cool, secondly i always did all the engines breaking in for my planes this way and never had to replace any engine until the plane crashed
constructive criticism:
I saw 4 mistakes in your method.
1. never turn prop at a new engin that slow as you did
2. NEVER use electric starter to prime
3. when breaking in a new engine, set a very rich mixture. So rich that the engine just run like a 4 stroke engine at full trottle. Because the overrich mixture will cool the engine from inside and wash out the metalparticles caused by the breaking in process.
4. never let it run @ constant speed – change the trottle position constantly
@obsessedwitmagic u stupid
@mrfourtysevenman this is because when the engine gets hot the internal parts fit together better
My engine on my RC car runs quite cool a swell (its a nitro star G3.0) maybe thats why its so fast, lol.
@alishanmao lol, unless ur drunk or high on fumes, then you bash it in dirt during a little thing i like to call A CRASH!!!!! CABOOOOOOM!!! lol
@obsessedwitmagic LOL man, this is Airplane engine. It doesn’t need an Air Filter. cuz it flies in the air. we do not bash Airplane in dirt.
NEVER run ur engine without an air filter if any dirt gets in u need a new engine. especially for break in
@rpg711 this engine never got over heated with 30% nitro. I have flown it in hot summer days as well
@alishanmao fuck man 30%? plane engines should be using at most 20%. That engine must overheat like a mofo.
ah.
well these engines that I used, were refill and fly, refill and fly
does it require cool-downs? because my supertigre 61 had amazing compression yesterday and after running it for the first time, it is hard to start and i think some of the compression went away. but after cooling it down it seems my compression came back.
well they just get started in reverse sometimes. but thats bad for them
how do u reverse a nitro engine
30% nitro
what % fuel do you use in the planes? like my jato i run 30%
I fly my Nitro planes often nowadays. and I leave the fuel in the tank, sometimes even half the tank. if I know i am not flying for long, I will put in after run oil, else in 2 or 4 days time I just leave them that way and next time they just fire up well
