Narrative:
While established in a hover in class G airspace and within what I believed to be the prescribed altitude limitations under far 107.51(b) and AC 91-57B; a formation flight consisting of several fixed-winged aircraft approached at a high velocity. No tfr existed at the time of the incident; and I believe that I was in compliance with all fars. The approaching aircraft were lower and closer than expected in relation to my drone. Nevertheless; my aircraft did not pass over; under; or ahead of the approaching aircraft; and I believe that I was 'well clear'. However; due to my concentration on vlos (visual line of sight); the flight of the drone may have exceeded 400 ft. AGL.irrespective of the legality of the operation of the drone; the low altitude of the formation; combined with the high speed of the traffic; surprised me and left few options to avoid a collision should such a maneuver had been necessary. In retrospect; although I believed that I was in compliance with the fars; the operations resulted in less than desirable separation from the fixed-winged aircraft.another flight was undertaken the following day without any reduced separation; but it is possible that the 400 ft. Altitude limitation was exceeded.
