im looking for the flight physics data for the trex450. i want to edit one of the helis i have to closely resemble my blade400 which sry to say was not part of fsone.. if you choose the model then edit you will be able to make a copy of trex and give it a name then after it loads you will be able to access all the physics data for the new model such as weight, drag. gear ratios,blade inertia etc. this is what im looking for. thnx
