Well that was the easiest thing i have done. Just broke in my mac .28 today, who said they are a pig to tune?

Its just 1 of those things mate
Some people who can tune other engines JUST like that - but when it comes to the mach they just couldnt get a suitable tune

Also to the argument of lower nitro for break in - DONT
Use what ever you are intending to run
So say ur gonna use 16% - break it in on 16% dont change

My cen F.Factor Atx has been broken in on 20% nitro, it has an NT-16 engine and from reading reports it's not a prefered engine. I was given half a litre of 20% nitro when I bought the car, and that stuff made it go like a rocket. Now thats run out I've gotta get some new fuel, so would 16% nitro make much differance to performance/starting and engine life? I'm not into racing, just bashing around in the field behind our house and don't really want to break kids ankles if I run into them. (Mind you, there is a kid I'll ask to put his head on the ground!   and get a N2O kit fitted for the event)

Thanx for any advice offered chaps and chapesses!

hi, when breaking the engine in, at the end of each tank do you just let the engine stop on its own when the fuel runs out or do stop it when fuel is low.

also how cool should you let the engine get before putting the next tank in?

thanks

I'd do it to about room temperature, but you could probably do it a bit higher than that.

hi, thanks for answering,

if i have not got a temperature gun is it still safe to run the engine in with the hyper 7 stock settings?

thanks

As a temperature guide I use the 'spit test'. You just put a small amount of saliva on your funger then put it on the head of the engine, if it evaporates in 1-2 seconds its at a good temp, if any quicker - too hot. If any slower - too cool! It's obviously only a rough guide but a cheap (free infact!) alternative to a heat gun.

I've never used the hairdryer for break-in. My swift was awesomely easy to break in, i followed the instuctions as they said the engine had been factory tuned for easy break-in.  Started on about the third pull, idled through the first 2 tanks, then 1/4-1/2 throttle on the next 2-3 tanks. Then slowly start to lean the HSN 1/8th turn at a time until optimal! Always starts on the 1st or 2nd pull and will still idle through a tank, and will always run right through a tank without stalling! A huge difference to my old car!

heay guys i just bought a acme condor. this is my first nitro car and am having problems getting it started. it wont idle just stalls 2 seconds after a remove the glow plug. i dont know if it is the fuel i am using (qwickfire16) could eny one help me with this problem .thanks

Ideally mate this topic needs to be put into general nitro thread, but i will tell you to open up your throttle a little bit more due to rich run in settings, also keep the glow plug starter on for a few seconds once its started just to help the engine build up a bit of heat so it will idle, due to rich settings the excessive amount of fuel trys to stop the glow plug from glowing and cuts the engine out.
The model technics fuel you are using is also not a very good brand mate its way to oily (thats why lhs supply it to you so even on a lean tune its hard to seize it up so you the customer don't come back for repair claims).
Use the fuel up and get some decent fuel with less oil content trust me it won't blow up if you can see blue smoke all through the rev range you are safe.
Byrons, o'donells, tornado are loads better and you will get more power from your engine.
Make yourself welcome by introducing yourself in the welcomes topic, anyway welcome to the forum mate.

thanks martin just tryed that working good just  used my second tank of fuel thanks alot mate

[revorocks]

nice section on the forum very helpful. my fav tips are to loosen the glow plug and heat with a hair dryer. they really help starting .

a nice warm engine is always easy to start

[herp_boi]

If i get my hyper 7 is it ok that i just break it in on the 16%/20% not sure yet ( not sure wether this is ok but it is an example) That i will be using long term because i cant afford to buy 2 diff types of fuel TBH Atvb Nick

[Zizzle77]

Yeah it will be fine, you'll be best off with the 20% if you can for a slight performance boost

traxxas actually recomend running in on the same % nitro you plan to always use.they also recomend building up throttle useage over 5 tanks and then start tuning
