The first 2 wings did not fail I am just trying to make the perfect plane for my house I live on 3 acres and dont like to fly over my neighbos property My bigger planes just arnt feasible to fly at home so most of my stick time is with my Lt-40 It is bult from a Kit ( I beleive thesse to be stronger It is converted to bolt on wings) and a tail dragger The fire wall has ben rienforced and I wligh with a tower hobbies 75 2 strock with a 14 X 6 apc prop. I am trying to get the shortest take off and landings as possible I would go to a 3d plane but am afraid in wouldnot survive long I land on pretty rough ground I have to run 5 inch mains to run over the uneven terrain And the wings are fully webbed
