RE: Boomerang Nano!!!
swps,
I went with BVM 3/16" wire struts with 2 1/4" BVM wheels and brakes on my Nano- now going on the 3rd season with 0 problems. However, I recommend going with Pro-link or equivalent struts if you intend to fly off grass fields. All (most of) my landings and takeoffs have been on pavement and the wire struts hold up just fine. My retracts are Spring-Air also- no problems here either.
