[rufinuf]

How can I tell if I didn't get my new tmaxx 2.5 broke in correctly. I have some symtoms that I would like to compair to anyone elses experiences. Can I tell by taking the motor apart if there is terminal damage(piston sleave fit). thx for any info!

If you broke it in to the book then it is fine. What symptoms are you experiencing? Maybe I can help (or someone else for that matter). If you idled the engine for about 2 tanks and didn't run it hard up until your 5th tank it should be fine.

i dont know about you guys but why would u break a engine in at idle? you need to break the engine in like you would run it. i have a article form extreme r/c and it says.... (shortened version)

the topic of breaking in a nitro engine is a touchy subject. ask 10 people and they will give u 20 different anwsers. everyone seems to have a theory on whats best. from ideling through 20 tanks to using high oil content fuels.

the idea behind breaking in a engine is to fully seat the internel parts so they move within eachother BREAK IN SHOULD BE DONE UNDER RACE LIKE CONDITIONS OR REAL WORLD CONDITOINS.

tank one- the first tank is the most important tank in the entire break in process. prime the engine by plugging the exhaust with your finger or turning the engine over a few times. dont overdo it or youll flood the crankcase. start the engine and let it idle for a few seconds and blip the throttle a bit to keep it running and rive it around. drive the engine through a full range of rpm's. go from idle to half throttle about every 2o seconds take it up to ful throttle. but only for a breif instance. you should be roling your throttle finger on and off the gas. abrupt throttle inputs are bad news for a new engine.


there is probably a few typos. ill fix them later or feel free to.
