The performance of radiomic analysis was investigated by the area under the receiver operating characteristic (ROC) curve (AUC) analysis. Independent-sample -test, Spearman’s test, and the least absolute shrinkage and selection operator (LASSO) method were used to select the most useful features from the original data set. T2-weighted fat-saturated (T2-FS) and contrast-enhanced T1-weighted (CET1) images were manually segmented, and imaging features were extracted. In this study, 3.0 T magnetic resonance (MR) data of 66 patients (40 males and 26 females, mean age years) with pathologically confirmed OS or EWS of the pelvis (35 with OS and 31 with EWS) taken from April 2013 to December 2017 were retrospectively reviewed. To determine if osteosarcoma (OS) and Ewing sarcoma (EWS) of the pelvis based on MRI can be differentiated using radiomic analysis. It is only going to be at slow speeds the worst, and i could live with flying sideways till the airspeed builds, that should not be that long.Objective. If P factor is a real problem, I can probably add an extra tail to the center, and if I really had to I could add a rudder that is controllable. The Twin Promax has not much torque, but will have over a hundred MPH Pitch Speed, so flutter on that one is a concern. The Aveox has a slower than 80 mph pitch speed, but torque is a problem. Hense the question about using differential elevon to help out a bit of overcoming P-Factor. ![]() Other sticks will be a Soaring only battery stick for very high winds with a wicked duration, and a hundred MPH attempt with a 10 cell zapped and selected RC2400SCR pack and 2 Promax 4011s with 4.7x4.7, or 4.75x4 or 5x3 props.Īnyway doing the torquey aveox first, and I need to counter torque from it, and at slow speed compensate for P-Factor. I am using the quick stick design so i can switch power units in under a minute. Using a Hobbico Gyro for pitch that can be controlled in flight to set gain. Installing an Aveox 1015 2Y with 4.4 to 1 and Castle 55 amp ESC and a 14.5x14 Rudy Freudenthaler prop. I am going to thin the thickness of the wing a bit. So this is going to be a Zagi 48 inch 3C. ![]() I weighed the elevon prior to thinning it, and found the balance point, that should equate to 50% area. So now I have a proper taper elevon that is 2.75 wide at the center and 1.75 wide at the tip. I laminated 1/8 bass to Balsa to make the elevon. TE is thick in the center of the wing and thin at the tip. ![]() I cut the center of the trail edge on the wing a bit to make it thicker so the elevon taper would more be in line with the airfoil. I ended making a 19% elevon area that follows the wing. ![]()
