Motor Breakin and heat cycles.

[safesinger]

I have the Exceed Infinity 1:10 Nitro with the .18 motor.
I did almost 3 tanks just idling. Then I went out and did figure 8's no faster than half throttle for about 3 more tanks the motor never got anywhere near 200f.
Then on 4th tank of figure 8's I started doing open throttle for small bursts for 2 more tanks and the warmest it got was 210f in center at glo plug .
After that I did another tank of gas figure 8 this time I opened the throttle up for a bit longer and it still only hit 215f in center where glow plug is outside temp never exceeded 130-150f.
Did I possibly ruin my motor? Sorry I am new to this so I am not sure if I am doing poop right.

210 is a bit high, especially during break-in. Keep the temps under 200 for a few more easy running tanks, keep full throttle pulls to a minimum until you have around 8 tanks total of driving around ran, I also do 3 tanks at idle, first tank just barely enough throttle to keep it running, second tank I do with a fast idle, and third tank I make sure the temp gets up to 180 or so. Your doing good just what I would say. I start to run more aggressively after 8- 10 tanks and after a full tank of normal driving keep the temp under 230, I personally like to see 205-210 at the head.

Each to their own I guess.
I was always under the impression you should break in a engine, at the running temp, which just over 200F.
Have done this on a few engines, they run mint, and have so much compression even after over 2 gallons of fuel.
I even used a aluminium wrap or heat gun to keep the engine at around 200.
To me 210 is perfect

I must say I have had a few vx .18s and only recall reading temps of 230 with a leaner tune when doing top speed runs, but the fuel I use is higher nitro percentage and is known to reduce running temps while still being a safe rich tune vs many other fuels

Each engine can be very temperamental. I find traxxas engines just run hot, in the 270s to be honest, and no matter how rich, temps will not come down. So, I run them at those temps. they run great.
Actually, what I also figured out is that once properly broken in (gallon or more), temps on Traxxas come down a lot.

VX18 I have to say its the same as yours, runs very cool and easy to tune, responds to leaning/temp increase very well.

I found a gallon of Nitro on Amazon called

Torco RC Fuel 20% Nitro for Trucks & Cars.​

It has like 14% oil in the mix which I heard works great with the Exceed motors. They say it works great for all motors keeps them cool and runs motor very well.​

It has great reviews of course there are a few negative ones but for the most part it is well rated.
And I like that it's Pink/Red in color easier to see it go through the gas line. I haven't used it yet I am just assuming it will be.​

Just listen to me, and get 30.

Tune accordingly and watch your temps for a tank or 2, You will never go with any other fuel once you have experienced torco 30, I put my word as a man on it

I never used torco, but I always find myself getting 30 or 33% over 20.

I NEVER let it idle through tanks. I have used the heat cycle method for many years, and my original Savage ss still runs like a beast, still with the original engine, my og rs4 3 rtr engine lasted through many gallons. 210 is perfect, get it up to temp, but only run it at that temp for 2-3 minutes doing large figure eights (on pavement). Easy on the throttle, easy off, no blipping the throttle. Then put the piston a bdc, let it completely cool back down to ambient temperature and do this for 10 cycles. Then I'll run a few tanks without really beating on it, and start fine tuning, my engines have always run amazing, and lasted a long time.

Nailed that

Why not just run the motor slightly rich for no less than 5 minutes twice. ABC ENGINES do not require lengthy break in periods. Ringed engines require lengthy break ins, but you don't have a ringed engine.
