One thing to consider is that the NTC3 uses imperial screws/bolts etc. If youve got metric allen wrenches etc you may need to buy some new tools (imperial) to make working on the NTC3 a bit easier.
I think the Kyosho RR you were/are running has a centax clutch?....bear in mind the NTC3 Factory Team uses a 2 shoe clutch, so you may want to "upgrade" this to get the adjustability of the centax clutch.
Theres a few nice K-Factory hop-ups available to enhance the NTC3 mentioned in previous posts here.

I post this in the NTC3 thread, because I don't have these problems in my AD2.

I have a recently broken in MT12 in my new FT NTC3. The problem is engine temps are above 270 without a body. I slowly richened up the mixture, but the motor will then flame out. Is this normal behavior for this motor / car? I've had MT12s in my XXXTs for 3 years, and I've never had temps near this high.

I don't have these problems with my AD2. Which leads me to beleave I goofed something in assemble of the NTC3. Car seems to be a rocket, though.

Thoughts?

Hows the clutch? Is it sticky or nice and smooth? What kind of plug is it Turbo or Standard you could try and go to a hoter plug.

my MT12 has a standard plug. The clutch is silky smooth. The wear is normal - very little on the inside of the housing or shoes. No evidence of slipping or rough engagement.

hi guys. i am new to nitro on road, but not to rc racing. i got a second hand ft ntc3, loaded with extras. the only question i have is this: if i went from a 48-54 gearing to a 48-52, what will the difference be? can i just change the 2 speed to get some more top-end back?

The main difference I`ve noticed between the 54 and 52 tooth spur gears, is that the 54 seems to get the car accelerating much harder off the line and out of corners......no noticeable difference in top-end at all as the 54/52 spurs are 1st gear.

Turn the drivetrain over by hand and see if there`s any binding happening, the drivetrain should turn over very smoothly and easily......also check that the gear mesh isnt too tight between the pinion and spur gears.
Another thing to check may be your fuel.......bad fuel often causes flameouts at higher temps.

Hey guys, thanks for the tips. I'll try a hotter plug and different fuel. The fuel I have runs fine in my AD2, but the MT12 doesn't get that hot... I think you guys are on to something.

Is 270 too hot for an MT12? Does any have experience with this motor and an NTC3?

I've ran 280 on NS12. I've noticed older engines run hotter due to less compression.

I run my MT.12, around 250-260 with sidewinder 30%fuel. I've had it for two years now and still running strong.

Thanks guys. I put new 30% fuel and changed my plug. Flameout problems are gone. Oddly enough engine temps are down, too.
