Default RE: Sundowner 50 with a YS110??

Still4given

I have a YS 110 in my sundowner and have had it to 141mph with 3" wheels (long grass at the field) and a 14 x 14 apc prop
I belive I can get 150 with a 12x14 apc prop and 50% nitro,I have alsoported my engine whichgave me quite a few revs,I will post the data this week from my egale tree system
I can say that with this plane and engine you must fiberglass the firewall and the servo tray or it will fail

I haveattached the data on a different post as Mongo2
