I just ordered me a new Edge 540 66" from VectorFlight after reading all the great things about their Planes, and Service here on RCU. Couldn't hardly find one bad post about them on RCU, and that is rare on here. Anyhow the Plane calls for a .90-1.20 size 4 stroke engine, and I have read most post on here about engine setups for the VectorFlight. Everyone seems to lean towards a Saito 1.00-1.20 or the YS 1.10-1.40. My delima is that I am fond of the Magnum 4 Strokes, and I have had my eye on buying a new 1.20 Magnum for this Plane, but I don't think I have read where anyone has this particular combo. So I am just curious if there is anyone who has this setup, or if anyone has just cause why I should buy the Saito 1.00 instead, which is my second choice at this point. The YS is not an option at all for me. Nothing wrong with them........I just don't have it in the budget for this project. I admit that the Magnums don't sound quite as good as the Saitos, but the Magnum 52 4-Stroke I have on one of my 40 size Planes runs like a champ, and has been super dependable, and the price savings by going Magnum is more than just a couple bucks in savings that can be put towards other projects. I would just like to get a few opinions on this.
