I have several of the Happymodel Whoop 1S AIO boards (inc ELRS). Been happy with them.
One is in a Dave "C" NanoLR, ROBO 1202.5, 3018 2 blades, powered by 3300mAh Li-ion.
Weighs 60g without cell, 108g with 3300mAh. Its a 3D print body with carbon insert strips to arms. That weight is LESS than the production Rekon3.
In ground effect 0-8cm up its motors sound rough, otherwise it flies superbly well, quiet, smooth, and relatively powerful, actually capable of power loops in first half battery life.
Cruising is 15 minutes min, and if not windy, nearer 20.
The issue is that in an indoors sports hall or at home while speeds are low the core temp climbs too high and it shuts down. Can get to 85 plus inside a minute hovering or in low forward speed.
Not had it shut down outdoors cruising about, even last summer, discounting current 5-7C max's here currently.
I have done what I think is the obvious, cleared better cooling holes on frame than standard frame, done some adjustments inside Betaflight.
I realise that I might be pushing the FC harder than ideal, but its SO close to being really good so I want to explore if I have any leeway left for improvement.
I won't "lead the witness" with my current Betaflight settings, which were mostly prod and hope conducted!
Ideas please?
