I posted yesterday about a second plane and due to the response and what club members told me, I ordered the Sig Four Star 40. I'm interested in powering it with a 4-stroke. What's the appropriate size.....I'm guessing the .52. Are there any 4-stroke engines I should keep away from? I'm thinking about the OS just cause I've always liked their products.....what do you think? Thanks in advance
Last year I had the 4*40 and used the OS46Ax 2 stroke turning the 11X7 APC prop and the plane was a screamer. I then bought the Saito56 and went to a 12X6 and the plane did slow down some but still flew well. I did have tons of problems with the Saito (I never seem to have luck with them) so I went will the OS 4 stroke and same prop and the plane flew very well. Not tons of speed but gobs of pull and vertical.
It took a little getting used to going from a screamin' 2-stroke to the 4-stroke but block out the sound for a little while and just watch the plane and it all comes clear.
