No Brakes!!!
« on: October 08, 2022, 09:44:05 PM »
I have a electric setup on a Nobler and the prop keeps spinning after the timer shuts off. It slowly spins and does not allow me to glide the plane in.
I read a thread that explains my exact dilemma but need more info.
It’s a BA ESC with. FM-9 timer. The BA is basically a mantis.
Looking at another thread the Mantis has a default of breaking off.
Do I need to change it to “On” in order to stop the prop? Or “Soft Break”?
Thanks

I'd try Soft Brake first. It stops the prop a bit more gently.

Also, the Default list says that Cutoff Voltage is 1 (2.8V). I'd consider changing that to match your battery pack. Or not too much less than what your pack is.
I built a Blue Pants as a kid. Wish I still had it. Might even learn to fly it.

Thanks. I’ll adjust.

Are you SURE that the slowly spinning prop is what's not allowing the plane to glide in? I saw a bunch of slow spinning props on e-stunters a few weeks ago that had no trouble gliding in to a decent landing. I'd wonder if the CG is too far aft.  H^^ Steve

Another thing that will KILL the glide on a flapped stunter is having "up flap" at "neutral elevator".  n1 Steve

Sailplanes use that for just that reason - to kill the glide.

When Winfred appeared at the Nats with his infared throttle, a bunch of flok watched intently, saying that it was a "crash" if the prop was turning when the wheels touched the grund. I guess that's changed.
