tuning

[smittyzz]

I'm not aware of any manufacturers who will honor warrantires once fuel has been put in the engine (without fighting tooth and nail). I could very well be wrong, but have read many scenarios where they simply claim you did not break it in correctly.



Can't argue against this, as i know many people who race--there engines are beasts, and they heat-cylcled. At the same time, I know many who did not heat-cycle and have just as strong engines (if not stronger). I guess my point is there is no data points to back it up either way. So IMO, saying that if one does not heat-cycle is doing a disservice---not sure if I agree..(And I realize you are not saying this.)

In the end, it's whatever you are comfortable with, as long as you follow basic principles.

I've decided heat cycling,
but I also want to get my motor repincher for a winter beater, who does that?

You can run it in the winter or cold weather with no problems. Seal up the electronics and wrap some foil around the head to keep the heat in and your good to go. If you hit the snow just be sure to dry it off when your finished. My ol' girl has seen plenty of ice and slush over the years...

sounds good,!
about how much would you say for tin foil?
and I know I have a splash proof reciever but will it do anything to my servos?
I think I'm going to seal my battery box, as I've got a 9.6 v that I brought down to a 7.2 so I don't have need to go inside the box anymore as the charging connection goes through the side with 2 little holes for the wires. (9.6volts was too much for the truck and made my throttle servo spas out and jitter. but all is good at 7.2=)

At about what temp do you start to use the foil?

 

[Cornholio]

Automotive grease works wonders when it comes to waterproofing and its fairly cheap. On both of my servos I took the bottom piece off and filled it full of grease so the electronic board is protected. You can fill the top also but it will slow down your servo by quite a bit. When you put the servo back together wrap some electrical tape around the seam.

That all depends on your engine. When it gets down into the upper 30's I have a tough time getting up to running temp, so I wrap half of the cooling head with alum.foil and it brings my temps up nicely.

I think nitro engines prefer colder temps. The winter (30's-40's) is when we probably run ours the most. It's the heat (105-115) that you have to worry about.

I've never tried foil in the winter....but certainly don't worry about running in colder temps. You're engine will warm up. Just give it a blast with a heat gun or hair dryer for about 2-3 minutes, and it should be fine.

 

[smittyzz]

it's between 35~45 here and I'm going to be breaking it in hopefully today but if not tomorrow, I'm probably gonna use foil and or tape on the head!

Enjoy the break in!

Well when I got everything ready, I found that when I went to pull it to start it, it slams the bottom of the glow pug, and when it's running and I feather the gas you can hear a kinnd of medal noise, so there sending a. 21 replacement. hopefully no issues this time

although it does run crazy fast, it ate through a rim... and its now only 2we because of it. goes crazy fast. but glow plug is still a touch wet, but I'm running it till my replacement comes or I have to send it out

 

[smittyzz]

scratch the replacement. . that eBay guy is not helping at all.
and I've been doing some reading that it's partly the one way bearing and the compression, it being a new motor an all
any ideas?

In all the years I've done this, I've never heard its better to run them in the cold.

 

[RoketRdr]

Yeah whoever thinks that an internal combustion engine doesn't like heat has never studied thermal dynamics or metallurgy and has no idea why a piston and sleeve are engineered with the exact specific tolerance that they have. In over 30 years of tuning and racing nitro engines I've yet to see one perform and run better in cold weather vs hot.

That's absolutely true, and breaking one in is not a wise idea since they need to be run even richer to make up for the cold air.

That's the exact opposite of how I feel. Mine hates the cold weather for sure, it definitely prefers the warmer outside temps!

 

[alpinehyperlite]

I'd be hard pressed to even get a nitro started at those temps.

 

[maddmike]

I run year round and it does get into the negatives I know the engine dont run like when its warm but I'm too addicted to quite cuz of the cold. Thats why I stick to the cheaper motors I guess.

When tuned properly for the conditions and you take the time /preparations to keep the heat in the engine, the engine will produce more power in colder weather compared to warmer weather but you better have a good handle on tuning and know what the engine needs in relation to the tune with the colder temps.
I don’t recommend break-in in temps 50F or below unless you have a lot of experience and have a good ear to what the engine needs/wants.

I broke mine in yesterday, it's running great! a lot of power and it screams! but when wot it light screams with a good trail of smoke, but is still running a little rich as the plugs wet.

any ideas on the noise I'm getting from the motor guys?!

 

[Non Crimen]

noise I'm getting from the motor

They tend to make noise. If it's not making any noise something's wrong.

What noise are you talking about? Try to describe it.

it sounds like the piston is hitting the glow plug, only does it when the glow is it, when using pull start you hear it most and when it starts it sounds kinda like a loose part vibrating. runs great has so much power and is so fast. it ate through 2 tires already (used junk tires)
