Thank you.

It's a pleasure for me to make these reviews (around 30 engines and around 10 cars).
And i'm very pleased if it's nice for you.

It's the first time I make it in english, so, I hope you understand what I want to say!!!

I will update soon.

My next challenge will be very big:
panorama of most af .21 off road engines ( I already receive 9 engines )

The Tuned sleeve is little different.
The ports are more agressiveespecially in the angle...

The cater cap is threated to decrease the friction of the conrod.



The heatsink is milling.
The plug is now Turbo, and mounted on a separate insert.





The carb is also black treated.

And now, the crankshaft.
The diagram would be agressive.
Nice turbo scope...





These is the exhaust.
The FLS system is great.
1/4 turn and it's OK...

holy cow that sport version looks crap! I guess the price will be added up with the fls pipe and little extras you get to bad for the let down on the motor
The fls pipes are strong! such as from my previous ninja fls, I got a nice t-bone which broke my ninjas crankcase! Lets hope grp will make some other pipes for their engines.
All in all still looks very ninja like but will be interested to hear some track tests to compare.

Great reviews romuald31

What is crap ?
20 years ago engines looked like this sports engine and even today there are a lot of people with current highend engines not getting to the laptimes as the topdrivers from then.

We are a bit spoiled with the idea that only nice shaped parts and fancy porting will make a motor fast.

So yes, for our standards it looks crappy but I still think it will be a a faster option for all those RTR drivers and that is the purpose of these kind of engines.

Unfortunately, 20 years ago, the price of this sport motor was the price of a top end engine. People expect the engines now to come standard with what was once new technology/fancy engine work. Maybe not as much, but the sport does look very basic to say the least. In 1/8 buggy, a Sportwerks .21 or.26 has more features/internal work done for a very low price. Its what is now considered to be standard, not extra.
