dont go for a 18 engine. probly wont fit right.1:10 cars are made for 12 / 15 engines but 15 has les hp and power then a good 12 engine.
i got the tz 12 3port 1,55hp. and oh my god. that thing rocks.
on this forum you wont find much info about them. try
www.rctech.net
there are like 50 pages of info on them. all say this engine is crazy and as fast as a novarossi.
the 3 port has crazy torque. great for a smal / med track
if ya want more top speed then try the 5port that one has 1,62 hp. dyno test shows the peak near 1,8 hp.
i just broke in my engine. have to say. its amazing.
i got a g4 mongoose car on foams and it just pulss away freakin hard.
all i can say is 'that iam very happy with this engine. easy to tune and holds it very wel. cost is low and the power en performance just like the italian made engines.
just make sure you break in the engine the right way and use a hairdryer to warm it up. otherwise you wont be able to turn over the flywheel on the starterbox.
oh yeah. engine starts very fast.
need info. just ask
