RE: Can I use Saito 65 in LT-40???
sure, i think it would fly fine....
the 65 would have slightly less power... but that is not a concern with the LT-40
as for fuel... why do you need different types??? You do not need different types for each motor.. pick a good quality fuel and go fly
I use Powermaster 20/20 in everything and it works perfectly, but there are many others.... just grab your favorite 10 or 15% and go fly
