I tweaked the varient from Linkadrip and changed the engine to an OS .91FX with an APC 15/8 prop to match the model I have waiting for my return to the States later this year. I also changed the CG and a few component weights to better balance the aircraft. You will first have to download and import the Model Twist 40 EA. I also have a pretty good Twist 150 Color scheme: Twist 150 CS
