I am thinking of purchasing a asp 4 stoke to go with my new Seagull Extra300s. Problem is that it recomends a .46 2 stoke with no indication of 4 stoke power. I would like enough power for vertical performance. I have no experience with 4 stroke power as i've only used 2 stroke before.

My questions are :
1)What would be a recomended 4 stroke for the model?
2) Are the ASP 4's any good?
3) Any difference in starting and setting up compared to 2 stroke.

Thanks for any help in advance guys.
