I don't doubt for a second that you know your stuff.. However, I did break that Caster in without preheating, sent it in to get the rod changed, and the guy was like, don't bother, it doesn't need it..(turning down money in the process..)

Only mentioned this cuz somebody above seemed to say that if you always preheat you're not really breaking in...(if I understood correctly..) Which kind of makes sense. I would think there needs to be some resistance - overcoming that is the point of the break-in process, right?...

Not saying do three tanks and letter' rip either.. Just that I personally suspect that pre-heating is overrated..

If my next engine blows up I will admit it.. :D

I have heard of guys having rod failures, but it wouldn't surprise me if at least some of them were doing the few-tanks-at-idle kind of break-in then off to the races while the engine still has too much pinch.. I have also seen guys who took really pedantic care of their stuff - preheating and alll, and still blow up rods and engines(VSPEC's mostly...)

IDK, I don't claim to be an expert. I'm not even currently racing.. But til I have a rod failure I'll just continue with my normal heat-cycle break-in and not gonna bother preheating...(OR changing the rod..) Especially with engines like the (Go-based) Precirotate D5 and Argus going for such cheap prices.. For those prices if it lasts six gallons and blows up, fine... I don't want the hassle of preheating or changing a rod, so I'll just risk it and get another one if it does blow... Attitude might change if one of my engines ever does blow due to rod failure.. But til then, I ain't gonna bother...

it isnt just about making the engine last longer tho :)

the engine when preheated will:

start the instant it bumps.
be at race temp instantly.
use less fuel as you dont have to warm it up for 3-4 mins before racing.
saves on plug wear.
saves on clutch,bearings and drivetrain wear.

ok so the above points are minimal in their own right..but add 3x4 mins is 12 mins every race day your wasting on fuel and wear on everything just warming up.

so when someone does 10 gallon on their engine preheated...you can be sure its 10 gallon on the track..not 9 gallon on the track and 1 gallon on the starter box warming up :sneaky:

there really arent any negatives to preheating,everything that comes with it is a bonus :)

when we first got the new go engines last january we abused them on purpose,no preheating,2 tanks run in then hit the track on race tune and drove it like i stole it lol
the engine lasted fine with no issues..but preheating just makes sense.

OK, those are some good points..(funnily enough, about saving on wear and tear on other components besides the engine.. ;) ) Fuel is expensive too..

Everyone to their own thing dude. I just have a thing about torturing perfectly good motors for no reason :confused:
These are such great little pieces of engineering, it seems a shame to not treat them properly. But hey - your motor, your money, your call. I just wish I was your local GO retailer :lol: :cool:

I see. So what you're saying is, any Go engine not preheated is destined to die an early death and make money for Go dealers? OK...

NOT what he said at all...in ANY engine (and that includes the car you drive to work) 90% of the wear is during the time it takes to warm up to operating temp from cold..it's why people who only drive their cars short shopping trips of a few miles will always wear out in fewer miles than the salesman who drives 3000 miles a week practically non stop..Engine tolerances are designed to be correct when the engines at temp..ie where it will run at..This is way more important in our tiny nitro engines as they have no piston rings to take up any play and let's face it rev to ludicrous levels..36,000 rpm for gods sake..even my fastest tuned bike is screaming at 12,000rpm..and that= 182mph....so preheating eliminates this heat up period..as mentioned above it also eliminates the choking and spluttering as it runs rich whilst cold as the fuel isn't vaporizing properly..No waiting..no temptation to screw around with the carb settings cause it's not running right (it will soon as it's properly hot) if you can't be bothered.fine np no one is forcing you but there is simply no downside apart from a bit of time..and it WILL lengthen the life of your engine.:flaming:

hmmm rant I think..sorry regulars..:nod::nod::nod:

Saving fuel makes sense.. Sparing the clutch and drivetrain, yes..

But I just don't believe that, if I do a sensible heat cycle break-in and go easy for the first half-gallon, that the preheating guy is gonna get THAT much more life out of his engine.. I mean, most people are looking at a rebuild by eight gallons or so anyway.. So what, are you going to wait til ten just because you preheated?

I would preheat if I could. I can't though. And if I could, I would only be doing it because everyone on the internet says to do it.

I was talking to this mechanical-technical German guy in a company the other day btw, and asked if it was really necessary to wait for a modern car to warm up before you drive off. He said no, that's no longer the case(kind of like automatic transmissions sacrifice fuel mileage.. Outdated assumption..) Of course, you shouldn't be starting and then immediately redlining and burning wheelies from your parking spot.. But I'm not doing that with my nitro engine either. I'm taking those 3-4 minutes to let it heat up before I really start pushing it.. It's not like preheating is cost or effort-free either..(some of these new preheating thingies cost nearly what a new Go costs.. NOT including energy for it..)

I'm not trying to start an argument, either.. Just a discussion.. - to try to better understand exactly how necessary preheating is. I remain skeptical... Good if you can manage it? Sure.. Life-threatening to your engine and an absolute must like so many seem to suggest? I doubt it...

After break in it is not that big of a deal. However it is crucial while the motor has metal pinch. Just because you have had some luck with breaking in a motor without preheating doesnt make it right. If you start a new motor cold you are putting tons of unneeded strain on the bearings, rod, rod bushing and the motor of your box.

I also do not understand why you can not preheat? There is no electrical connections where you break in your motor? Get a 12 volt hair dryer and just hook it to your car battery. Just a thought.

Bottom line, both Go Engine USA and and Go Engine Taiwan recommend preheating during break in. Regardless of what anyone else says, this is what the factory recommends. I have discussed this at length with the factory owner and engineers. Heat cycling and preheating is the recommended way of breaking in GX and GXII engines.

I run my RC's %80 at public parks or tracks with no electricity... The local track is closed half the year..:rolleyes: (why I gave up racing..) I mostly "bash" now - or just mess about at the park or run on tracks for fun, not racing.. But I have heard they want to organize some friendly races this year, so hope to race my SC8 (with Go GXR 5-port) against the truggies I guess... If things work out I've been thinking about getting a buggy or maybe a truggy and racing in some organized local and not-too-far-away races.. In Germany it's all too time- and money- consuming though.. Seems like to get serious into racing you have to also buy a motor home/mobile workshop and travel all around the country to participate in the various series'.. So I just remain a "casual" hobbyist til global warming improves the climate here so I can get out more...(instead of dxxxing around online all day in the winter... :o )

:nod::nod::nod:

also guys... I have a test batch of REINFORCED and HARD COATED 0801 pipes on the way. Availability is end of this week.
