Hyper Booster

[B&H Racing]

I'm running a 1s lipo a hobbywing v3.1esc and surpass v4 10.5t motor.
There is a distinct lag on the power delivery from stand still. It's fine once rolling.
I know the v3.1 has got an internal capacitor but I'm thinking about adding external capacitors also.

I have just come across the hyper booster, sky rc and yeah racing do one.

Has anyone got any experience with these and di you think it would help ?

Thanks
