There are 2 video links in this thread (Aug 8) that show comparable planes. The same CWM make/model. These are meant to serve as a baseline. Their takeoff elevations may be different, along with some of their components. They’re still relevant because they show expected behavior. We may need to change our build in order to reach this expected behavior. Or, again, as @menschel just pointed out, we may just need to try again w/ 6s. Or, it was simply the environmental factors and/or circumstantial factors (stick inputs, trim). If it’s helpful for you to see their build lists, I’m happy to work on that.
I thought that was listed already, but maybe I’m just remembering sending it to Rolf.
Motors - Tmotor 2814 710kv
Props - APC 10x7 (CW, CCW)
ESCs - Hobbywing Xrotor 40a
FC - Speedybee F405 Wing APP
Battery - 10Ah 4s 120c LiPo (plan is to move to 6s LiOn asap. Molicel 45b packs are being considered and may help us meet our needs)
Weight - I don’t have this on hand, will have to update this info when possible
Insufficient thrust is a symptom, not a root cause. The insufficient thrust could’ve been caused by a number of things.
