I agree👍 Rowen's thoughts exactly mirrored mine.
She might 'fly' with the 3S, or rip the shaft out or strip the gears😮
Figured Rogal might have the 2.5 gearing, it's the smallest of the 919D gears.
They go up to 3000, ~6rpm off load.
Ref. the 1060 ESC - I have a few, very reliable and easy to set up.
I use them with 540/550 type motors and I've not yet managed to make one warm up.
Yes they do have LiPo protection. It's a 2 stage protection described in the user manual.
Stage 1: Trigger point 3.25V per cell, i.e. 6.5V for a 2S.
At which point the ESC reduces power output to 50%, so you have a chance to tootle into a safe harbour😊
Stage 2: Trigger point 3.0V per cell, i.e. 6.0V for a 2S.
At which point the ESC cuts power to Zero, the boat stops dead and needs a tow or shove home 😮😭
Cheers, Doug 😎
PS I like Hobbywing Quicruns in general. The 1060 or 860 dual version for brushed, and the 16BL30 (30A) for brushless. Never had a problem with them.
