About this 3D model
This is a main gear strut for a Hobby King P-38. It is designed for their 10-15 size electric retracts (which I think are designed by FMS). They are nice and strong. I have a number of flights with them and they work great. I did print with 40% infill, but they are not too heavy. You need a 4mm dia x 20mm steel rod to connect the strut and the retract. The wheel axle hole is sized for M3 NOTE: I also have a nose gear strut with integrated steering arm. I will post that tonight
