Default Motor takes way to long to warm up??

Is it normal for a nitro motor to take about 3 minutes to warm up. Mine starts right up but for the first three minutes, runs like it is very rich (slow and lots of smoke). After the 3 minutes it gets right up to about 240 and runs like a champ. The motor is fairly new and broke in properly. Is this normal???

Default yes

You should pre heat it with a heat gun, it's better for the engine and doesn't wear the pinch out so quickly. You can also put a pit towel over the head to get it to warm up quicker and more evenly. 240 is about right.

I try to get as much time (5 minutes or so) of heat into the car before it goes on the track for the "warm up".

Until the chassis is warm the motor is truly not "warmed up".

My GRP takes almost a whole tank to get "warmed up" from ambient temp. Now i use a heat gun and cut right to the chase.

that grenade you just got will be the same way she takes a bit to get worm before a race, and if you dont keep it reved up at the start she will die.

The Italian based engines take forever to warm up.. The best thing to do is like the one guy already posted is be out there warming it up during the heat before yours... You can also try cutting strips off a business card and placing them in between the engine and engine mount, that will help keep the heat in the engine rather then transferring to mounts, chassis, ect ect..
