damn, crashed the bird this morning on grass like i`ve been doing.

broke the tail boom this time so i pulled out the broken piece out of the boom holder , it`s shorter now and the tail is under the rotor wash from the main blades now.

fired it up and it was fine for about 10 seconds then the tail motor stopped and something started smoking along the top of the bird so i unplugged the battery.

another guy loaned me a spare tail and motor, so i`m in hold,
plug the battery in and the tail is running in throttle hold.

of course when i tried to fly it it piros out of control and has no tail authorty.

just don`t understand why it shorted out

Lost Tail authority
If your tail motor is running but you have no control, it is a shorted FET that controls the tail.
If you are good at soldering surface mount parts here is how I fixed my fried board.

Finally got around to replacing the P channel fet that controls the tail motor and success.
86 cents each from Digi-Key. MOSFET P-CH 40V 2.3A SOT23-3
Part # SI2319DS-T1-E3CT-ND
If you order 3000 you get em at 27 cents each.

Before replacement, burned view.

I think about the hereafter. I go somewhere to get something, then wonder what I'm here after ?

what settings do you have your soldering iron on for that type of soldering?

Setting ?
I set mine around 680 F. It is a pencil iron but the small tip looks like the end of a bat when soldering this tiny chip. I make sure the area is clean and not damage(the pads) then place a tiny bit of solder on the circuit board pads. Then while holding the chip in place I touch each pad quickly just enough to get the solder to flow.

I think about the hereafter. I go somewhere to get something, then wonder what I'm here after ?

When you broke the boom, you probably chipped the enamel coating on the tail wires and it shorted when you put it back together. Check that before you put that repaired 3 in 1 back into service.

that is possible. those 'coated' wires are kind of a pain to work with. especially with gorilla hands like mine.
