That fix is only necessary for importing a plane created for a newer version of RealFlight in RF 6.5. Normally a plane created for RF-9 will import in RF 7.5. The import signature that RF 6.5 looks at rejects new versions but the modification abaser mentioned replaces the signature in the KEX file with the RF 6.5 signature so 6.5 will load the KEX file.There’s a way but you have to modify the kex manually. I don’t know how but others here do so maybe one of them will chime in.
No problem I was happy to help and thrilled to hear you think my planes fly realistic. The hard part of modeling, at least for me, is the fact I don't have the plane and have never flown one. But in my experience if you model the planes dimensions correctly and get the weight and balance right the plane will fly close to the real model. But it's always great to hear it turned out that way from a person with the plane. Thanks !Technoid, Thanks so much for your input! It is really appreciated! Also, thanks for the links to the 2 Lasers. I currently have the 56" 230z in my hanger, I fly it all the time. Your models are very realistic.
