I have just got a NOVAMAX but I haven't tried it out yet. If I was you, I will buy something new and lastest one because EVO5 and C5 , both also not cheap.. I believe the price is quite close .
But If you are very new for 1/8, You might need to get a engine that easier to handle like Nova Rossi Race but infact, It's a lot of power as well. Then you get a better engine when you know what you want. and keep first engine for pratice .
Just an Idea
