Well, I bought what I thought was a cheap but beautiful Katana S 50cc ARF by Flight Models, only to be disappointed in repeated flaws in the building. The covering material is the worst I have seen, but I could get over that. My problem now, is that I noticed the fuselage tail has an ever so slight twist. Only after the stab was glued in with Gorilla glue did I notice the slight twist, which shows up as one stab being lower than the other side. The stab slides through two laser cut slots on each side of the fuselage for it. The wings were not on when I glued in the stab, and only after I got the wings on did I notice the stab is tilted in relation to the wings. What can I do besiges throwing it away .... to fix this stab situation? Trying to cut that stab out of the plywood fuse sides seems .. ??????
