Any 20% to 30% nitro will work ,I use Bones brew ,but there is other brands such as TNR ,Torcco fuels!
Here is what my NovaRossi engine looks like ,it a newer updated engine from 2012 an it is old!..😎
I am not sure ,but today's engines are more advanced an they range from $250 & up ,so pretty much ,that
engine is useless by today's standards ,the only way that someone would buy that ,is if they needed it to
restore their rc!..😎
I will try ,but the Rex engine was just Rossi's budget engine an the Rex name was used in many applications
such as aircraft ,marine & cars ,so I don't think the engine is really worth that much ,especially with not having
the original head!..😎
It is vintage NovaRossi engine ,Rossi went out of business a few years back ,their engines are quality race engines an
were considered the best an must have for track racing!
I know people that knows more about the Rex engine that I can get more info if you like?..😎
The Nova race head is an aftermarket upgrade that someone added ,it has nothing to do with NovaRossi engine ,
the head did not come original on that engine!..😎
Here is my Nova head for the AE. Pro 28.
