possible ESC issue?

[stamfordrob]

all.

new to the forum and i appreciate the help in advance.

my son has a SuperCub LP that he crashed and now has a few more issues other than too much glue and tape.

first issue which i think is a bad cel is when charging the charger clinks 3 times and then nothing else. i get no charge from battery.

second and reason for asking. when i plug another battery in that i know is good we get zero repsonse. no servo twitch or motor. i read many post stating that it may be the MOSFET but from all the pics i can distictly see that they are burnt. this one looks brand new.. is there some way to test this w.o desoldering? do you think that its burnt out anyway?

i turned the MOSFET over and have the following numbers. does anyone know of an alternative.

A non-responsive Cub after a crash has a extremely high probability the ESC burned out.
The throttle must be cut INSTANTLY or it fries the ESC with a dead short. Most newbies will fry at least 1 ESC learning this.

Does the known good battery charge in the stock charger? Crashes can ruin lipos too. If it's dinged/smushed/mushroomed/kinked/etc. there's a chance it's left the room also.
OTOH the charger ain't so hot so it could be that.

the bad battery was never used. it was new just never tested.

if you dont think its any of the diodes or the MOSFET where can i get an equivalent replacement.

Downside to the Cub-most parts are proprietary (non-standard) You have to get that specific part from Horizon or a dealer. It also houses the receiver so has to be the correct channel.
