Go with the strip airlarons with one inch under each wing tip. Use a servo on each side with a Y connector. That is how mine is set up, wore out a Saito 45 completely ( was used ) and now have an OS 61 on the plane. This is a really good set up for beginners and makes the plane a joy to fly....It's the best for what it is...a solid trainer that you really don't get tired of.
