Chuck, If it's not installed already, fuse mod
. is an absolute must!!!
This will save your 4in1 from becoming toast. Other mods and upgrades.... Super Skids, then main motor, then LiPo battery. I would recommend in that order. However, if this is a new heli, just charge batt. and learn with the stock stuff. Save upgrade money for parts.... you will need them... Maybe this helps somewhat. Take care and fky safe.
p.s. if you haven't found it yet, there is a whole forum dedicated to the Falcon 40. 303 pages long. Ain't nothing about the F40 that hasn't been discussed in here. Here is link to page 1. JB
