Lift efoil remote for DIY

A friend gave me his spare lift remote which is just missing the spring for the trigger which I can replace. Was wondering if there is an after-market compatible receiver that I could pair it with for a DIY project.

Thanks.

I think even if you get a receiver it does not help you as I think they have their own data protocol, don`t think they just translate the BT signal and send a pwm signal to the ESC that you could use on other ESC…or do they?

That’s what I figured. I’ll fix the spring and my friend can use it as a spare for his lift efoil.
