I have a Sig 1/4 scale Spacewalker II that i had a Saito 182 Twin on it and it realy looked and sounded great but i used more fuel trying to tune it than flying it LOL.
I bought a YS 120 put it on my plane and have ran it several times and it runs great but i havent had a chance to fly it yet.
All these post have been a great help because this is my first YS engine I have OS or Saitos on my other planes.
I am useing Wildcat 20 20 fuel and a OS F plug and a 16x8 prop.
Does the prop seem to be ok for this engine and plane?
I hope to get to fly it in the next week or so. Any info on these engines would be greatly apreacated.
