Sonicmodell F1 bungee hook plate

I found that reliably throwing the F1 when using a 4s 2200mah was nearly impossible. I use a bungee launch for my bigger wings ( Opterra, Z3, RV Jet). Bungee Launching allows for a stress free launch 100% of the time. Obviously, this replaces the entire bottom plate on the F1. I used ShoeGoo to glue it in place.
