Default A 4 stroke engine to start with?
I am looking to buy a 4stroke engine 70 size for my first kit,a Tower Uproar.
Between OS FS 70 Surpass and YS 63FZ-S,which one do you prefer?
YS has lower weight than the OS,but OS requires only 5% nitro to be happy,in addition to the YS that needs 20++.
So,please help me to decide.
Also i haven't any real experience with 4stroke engines,so i am looking for a guaranteed reliable and easy to tune engine.
Kostas.

P.S. YS costs 30$ more[>:]
