I just got the X312T engine and i am wondering if you have to heat the engine up with a heat gun/hair dryer before starting it for the first few tanks.
It says that because of the unique CRF technology you only need to run it in for 2-4 tanks. Do i still need to heat it before starting?

I would always recommend to pre-heat an engine before starting it up. Be it CRF, Picco or Novarossi. It helps the rod maintain its life since your reducing the stresses created on it.

Is it normal if when i carefully slowly turn the cranksharft it gets hard when the piston is at the top of the exhaust port.? But i didn't turn it any further to evoid damage.

You don't need to heat up the engine before breaking it in.

Just run it rich for a couple of tanks and make it leaner so that it starts to have power after 3-4 tanks. After that, start fine tuning to get max power.

The pinch at the top is normal.

But with this one it gets hard when the top of the piston is level with the top of the exhaust port. won't it damage it?

The pinch is always at the top it's normal.

i have 2 of these engines , awesome work of art and power for price. my advise is just follow the manual. no need to pre heat the engine what so ever . and if u ever open the engine up dont try to push ur piston trough the liner . it will go right threw . when these engine are cold they seem not to have any compression or very less. but that's what special about these little power packs . never let the engine run over 120 degree cel. and the gearing on this engine are set a bit differently .

hi, run my X312T for the 1st time last Sunday, it was fantastic. This is Kyosho version with goldish head. Can't compare much powerwise but based on what I've seen our local track, comparing, I wasn't any slower. This engine seemed so easy to use, let's see how long it will last.. Thumbs up so far!

Thanks for all the help guys!

What glow plugs are you using?

i ran in my engine last sunday at moorebank and it was great. i am currently using a kyosho 6 turbo plug. the one that comes with the engine. it seemed to run well. but i can't give you a solid answer because i have only run 3 tanks.

I think the one that comes with the engine is an Orion REV plug (medium #6)
I've been using the cold REV plug lately with 16% nitro

So how are these engines performing? I really like the look of them and am seriously considering this as my next engine.

Let the feedback roll in

Opinions anyone?

lots of rev's in this motor , need perfect clutch setting and under gearing to get power to the ground. if your running on a small track i wouldnt get this if ur running on a big track go for it. there are better promising engines for the few extra$. each to there own.
