Default GP Extra Engine Selection Question?

I was wondering what engine would give unlimited vertical for the GP extra 300s? I was thinking about a YS 63 for it, because I really want to put a 4 stroke up front, and it has a lot of power.

Thanks for your help!

Which size Extra? GP makes a .40 and a .60. I have the .60 size with a YS 91AC, and it has Unlimited Vertical.

Its not a four stroke but I fly a forty size 300S with a TT .61 propped with an APC 13x4w that is pretty impressive.

The YS 63 can swing a 13x6 APC prop and it has 1.5 horsepower. I don't know the rpms off the top of my head though.

The YS 63 would be SWEET in that thing!
