This new 21cc was developed by Valley View RC and was designed for airplanes with smaller cowls.
Using an angled 1/4 - 32 spark plug this engine is only 5" from bottom to top allowing it to fit into a smaller area.
The muffler has a slide on teflon down tube with a clamp so you do not need to make a large hole in your cowl.
