Default Giant P-51 Mustang destroyed on take off

A very expensive electric conversion destroyed within seconds of take off. Even the most experienced pilots make small mistakes which can have disastrous consequences.

May not have been pilot error. I noticed one gear went up but the other one didn't. That could have drug the power level quite low to where the receiver just couldn't control the servos properly.

Looks like a typical tip stall to me, and pilot error.

The gear never retracted, not sure what you saw but the doors open on that model before the gear retract.

Hard to say for sure without knowing the pilot background but he took off too early, dumped lift in a near stall with full speed flap servos, and it snapped over.

If I had to guess I'd say someone was spending too much time developing bad habits by yanking foamies around and tried to fly a heavy, built-up warbird that way and it bit him in the toosh.

Yes Sir. Simply tried to yank it around too hard while going too slow. Excessive elevator throw could have been a contributor as well.

Yeah, Low on power, minimum airspeed, clearly under powered, turned himself down wind right into a stall,, that's both builder and pilot error

My money is on pilot dis-orientation. Everything was shaky but relatively well until the plane started in the direction of the pilot. At that point he should have leveled the wings but instead put in left aileron which accelerated the spiral. Will never know for sure but to me personally it was clearly pilot error.

One big hint is the amount of up elevator you can see while it's on the way down.

Been there. Done that. It took me a long time to adjust to flying to me. Once I started moving the stick towards the lower wing, I got the hang of it. This pilot need help

More money than brains?
Lack of training?
Lack of understanding?
Lack of adult supervision?

A more common event than many will admit and thanks to available technology, a far too easy event to replicate pretty much anywhere.

For as long as I have been in the hobby there have always been guys flying airplanes beyond their skill level, now we have the internet where guys can comment and attempt to advise beyond their skill level. Of course over inflated egos at play in both circumstances. The thing that really needs to be taught better is airplane set up and trimming. What I saw in the video is an airplane with adverse yaw, too much control throw and maybe too nose heavy. That combination when flown too slowly always ends the same way. Had the airplane been set up better the pilot may have had sufficient skill to keep out of trouble.

Ah yes Andy but the difference is that you and I can admit that no matter how long we have been doing something we remain open to learning more. Unlike some guys who " know everything " because they have read a few books and once built a Sig Kadet. Some even go so far as refuse to learn or accept information because they don't like where the information is coming from.

I also heard ,,,,, "I ain't got it !" ..... quite a few times...

You know the crazy thing is if you have any first hand knowledge of a "INFAMOUS " rc crash on video.. and you try to figure it out ... some people will never listen ... they just accuse the pilot of error. A buddy of mine had a Triple engine Italian bomber (Cant Z) crash... It went viral for awhile.. The kit was awful.. everyone that flew it crashed it..until people started figuring out all the problems with the kit.. even then it flew poorly. But everyone was ready to blame the pilot. I think my friend was the first one in the air for that kit.. The abuse he took online almost ended his flying...

If you think 2.4 is immune to interference (which is what a hit is).....................

Almost 60 years flying on 72 and I have never been hit hard enough to cause a crash. But I have seen a lot of brown outs on 2.4 systems. Some of which cause crashes. Part of flying is also knowing the radio environment you're flying in. I dare say, most do not!

I doubt that was the case here. If you look closely the airplane actually snap/stalled twice. Once that took it into the spiral from horizontal flight and again just before impact. Just a poorly set up airplane that was flown too slow. The pilot was also holding a bunch of up elevator the entire time which just kept the airplane in a deep stall and caused the second snap.

Radio interference is something many guys should understand a bit better. I have seen installs that sent a chill down my spine. One case even had an antenna taped to an ESC. Interference and brown outs are not the same thing. A brown out is caused by a dip in voltage going into the receiver. More common with Spektrum as their critical voltage on the RX is about 4.5V. I strongly suggest running 6V batteries on any brand of 2.4GHZ systems. You should also always have enough capacity so that under high loads the voltage will not dip more the a couple tenths of a Volt. Unless you carry a Spectrum Analizer with you to the flying feild it is almost impossible to know what RF is in the area. Common sense would dictate that the more Urban your environment the higher your noise floor will be. Range checks are very useful. I always range check prior to a maiden flight, after replacing any electrical component in the airplane and when flying at a new site even if the airplane has been glitch free for hundreds of flights at the home field.

Now that was straight up pilot error. I think Barracuda Nailed it.

I've flown many a Mustang and knew at take off and climb out it was over if he tried to turn, especially that sharp.

And.......
WHY DOES EVERYONE PUT 2 BLADES ON THOSE.... SMDH
