Not worried about money issues with this one.
I am going to get a biplane with a OS 1.60 already installed.
there is plenty of room for more engine but I want to switch it to gas.
the plane weighs around 12-16 lbs??

I want to switch over to gas to save on fuel cost and just have a plane to fly and have
fun with. no more glow plugs or glow fuel.

what would be the equivalent to this motor.
I plan on flying it 3d so it would need enough power to pull out of anything.
right now it has almost unlimited vertical but I want the tourqe.

any suggestions are very much appreciated.
thanks!!
