RE: 3D TRAINER - PROFILE???
I owned a PNP Tribute with the Evolution 36 engine. I was a lot of fun, but not worth the money. It was grossly under-powered. The evo engine would not hold a tune, and holds the record in my hanger for the most dead sticks. The Tribute airframe is very fragile built up balsa which will break at the slightest hint of a hard landing. The landing gear is so soft, that it forced me to harrier into a landing gently in order to take off again without re-bending the landing gear.
Once I bought a Mojo from SwanysHouse.com I sold what was left of the Tribute. The Mojo has a carbon fiber tube that allows for rough landings, and a Saito 82 gives more than enough power to pull out of trouble. It is not an ARF, but the kit is a very easy build.
