I have bought a new ARF model of AT-6. The next week I bought it the foil started to fold on the wings so I removed it. I was amazed when I saw that all the ribs were broken. Then I fixed and paint the wing. I had have on the plane 8.5ccm but it didn't take off. Now I bought a new 10ccm motor.
On what I must be careful at taking off???
Tomahawk
