To get bacl to the topic:

The NTC3 is great I have 1. Get the 2 spd upgrade. It makes all the difference in the world.

As for the 4Tec being legal - most places will allow it as long as it is the stock engine. If you replace it with something other than stock, then they make you go to the .12 - which a lot of .12's are more powerful than a lot of .15's anyway.

That is one thing I do not understand is how the .12's can be that much more powerful sometimes. Look at the spec on the manufactures website - a lot of .12's rock.

I am looking at getting a non-pull start .12 for my NTC3 but have not decided on which one yet. I do not know.
