How do I check the HI0404631 against my current frame?

Compare mounting hole positions and spacing to your existing frame. Although listed for Eagle, Freya, EX and SX common parts, a hands-on check ensures correct alignment.

Will this replace the original without modifications?

In most stock configurations it will, but verify that aftermarket additions or previous repairs have not altered mounting geometry which could require adjustments.

What assembly tips improve fitment?

Temporarily assemble components and tighten incrementally to ensure everything seats without strain. Use alignment jigs or straightedges where available to confirm correct geometry.

Does swapping the frame require re-tuning?

If the replacement restores original geometry, minimal re-tuning is needed; however, after any structural repair, verify flight controls and trim during a cautious test hover.
