The 50% Edge 540 was designed specifically for the 3W-275. While other engine combinations may work for the Edge, you may not end up with the same high performance airplane as with the new 3W-275! This engine is the latest design form 3W, incorporating the new split case design and the 6-tranfer port cylinders. This new engine design offers the highest power output and torque of any engine in its class. This is the only engine you need and the only one I recommend for the 50% Edge 540 ARF!
