Hey, I really your opinion for my kyosho v-one rrr shimo edition. Which engine should I use, novarossi or os? I'm looking for engine that quiet easy to handle since I am not using this for competition. I might be consider sirio to. Please give me advise and why should I choose your opinion

I would recommend Novarossi, I think you will get longer life from the other brands and you can pick up a Nova NS12 for under $200 ,visit serpentamerica.com they are the Nova importers .

Thanks for your thought bro. How about the RB concept? Is that a good one? Actually I consider brands other than OS and Novarossi
