Next flights will have to wait a bit - had an accident at the start of the following pack so drone will be out of action for a little while (hopefully not too long )
Funnily enough there was today a very similar sound coming from the quad (high pitch turbine-like noise) - did not sound like a bad resonance of anything - very clean and progressive/controlled,
I did not notice it before with the lower pitch props so could come from there.
Indeed - been crazy busy at work recently and trying to shake off some man flu atm - still hoping to get some full throttle runs later this week. Shout out to to Chris Rosser btw - I put a message on his discord a few weeks back letting him know the new high pitch HQ props did not fit the profiled prop holders - received today another set to get those to fit in - should easily go 200mph+ now - soon…
