Failsafe on flipsky vx1 remote

Hiya

Does anybody know to remove the failsafe on the vx1 reciever?

My problem is that I have re-sprung the throttle so that the full brake position is now 0% throttle and full throttle is 100%, this means that if I loose signal the reciever failsafe sets 50% throttle, which isn’t good.

I’m a bit stuck
