hi I'm so happy because i got my savage x 4.6!!!!!!!!!:):D:D:):D:hehe::D:)

buy when i read the instruction it says lift the savage off the ground for break in.when i do how fast do i go?half full?

P.S. if someone can you fully tell me the steps for the break in for a savage x 4.6 rtr it would really help me!
 
It should say in the manual, right? I'm not sure, because I've never owned a savage, let alone an HPI Product.
 
IMO that is the "Old School" method and is not good for your engine. Revving it up with no resistance (wheels off the ground) will cause you problems down the road. If you want to do a proper break-in try this:

The "Heat Cycle" method of break in is where as soon as you engine starts place it on the ground and begin running it in an empty paved lot for about 2-3 minutes at a time. Make sure it is tuned slightly rich and that your temps are about a normal day temperature of 200F/93C. After your 2-3 minutes is up shut the engine off, set the piston to BDC (Bottom Dead Center) and let it completely cool. Once it is cool start the engine back up, continue doing this cycle until you’ve ran around 15 minutes or so, making sure to place the piston at BDC each time it is shut off. After you have hit the 15 minute mark bump the running time up to 3-4 minutes. Start varying your RPM, and temperatures in the 200’s (ca 93C) is perfectly normal. What this does is create heat cycles on the components without adding incredible stress that could be imposed on engines when they are very rich and cold. After cycling the engine using this particular method for about 20-25 minutes you’ll be ready to finish fine tuning.

Note in the above it states 20-25 minutes total. I prefer to do step one for two tanks at idle to 1/4 throttle and step two for two tanks at 1/4 throttle with bursts to 3/4. After that you are ready to tune for speed.

in the manual when it says to have it off the ground, its for your first tank that you idle through so the idle should be low, and the tires shouldnt be spinning very much, they will spin a little since there is no resistance
 
Use the method shown above in the youtube video or the traxxas method. The HPI method won't do as good a job in breaking in your engine.
 
Hmmm....I am not for that method at all really. The biggest problem with that is lack of resistance which will allow the engine to accidently over-rev. Also it is harder to get the engine up to its proper break-in temp. I like to get the engine to 200 F with a heat gun before I ever even start it for the first time. Do a search for Heat Cycle here on the forum as was mentioned by RC Addict. If you need more help let us know! Do it slow...be patient. Break in is the most important part of your engines life....it can make or break it for sure.
 
I just broke in my LRP, I did traxxas/heat cycle. basically keep temps around 190-210, tank 1: you drive it 1/4th throttle bursts
tank 2: lobger 1/4th throttle (longer) bursts
tank 3: 1/2 throttle bursts
and so on, i tuned to keep temps between 190 and 210, put piston at bottom dead center when engines cooling, etc...
its pretty easy but deffinitely read more on it or check out squirrelod's breakin videos.
