This is one of the most versatile 2.5 inch frames on the market, with a range of mounting options front, center and rear. The A Frame arm design also gives it great strength and is considered to be best practice for reducing frame resonance.
The standoffs included with this kit are Nylon. CubeFPV replaces these with alloy ones. So if you purchase from my store you will have alloy standoffs. However if you are purchasing from another store, consider replacing the nylon ones with
20mm alloy standoffs, choose Hex shaped standoffs, so they match the cutouts in the TPU antenna mount.
