Flat spin makes for a great landing.

I had originally posted this to get some people's opinions as to what might have caused it.
Please don't post your nerdy aerodynamic explanation of what causes a flat spin. I was really wondering why I lost RC link with the aircraft. :)

Turns out my ESC was overheating, my battery was old and crappy, and my video transmitter was making things unhappy as well.

Holy cow!

A blown ESC isn't going to put you into a flat spin like that!

That is totally unrecoverable!

Did you get your plane back?

Plane was just fine.

Still not sure whats going on. This is the second time it happened, the first crash was the same thing but it never broke into a flat spin. It just nailed the ground nose first.

boom jeshot!

Hey I just had the same thing happen to my Twin star II while flying first person view. But it nosed into the ground like yours first started to but never went into a flat spin. I Killed it ! ! I think I need a UBEC for the receiver, have not tried it yet. But what happens is if you are pulling to many amps lots of servos possible you over heat your ESC and it shut of the receiver and you will loose total control of the plane causing a crash. Im not 100% on this but Im going to try it next. 5*

Also I would ck and see if there is some type of signle jammer in your area of flight. like high voltage wires microwave towers ooo and flying monkies. always ck for the monkies 1st. next is what we call the PFM factor Pure F@@king Magic. in NYC since 9-11 a lot of the com traffic was move over to the empire state building. for a short time there were comm. dead zones that effect even pocket key radio TX car alarms. & people were getting locked out of thier cars because they could nt shut off

Lost of main power.& uncommanded yaw. problem intermitant. 1) poor connection in your power distrubution cable possible cause moisture getting into your contact points in your wiring. at alt. water in the wires will effect your system diff then on the ground. could be vibration shaking wires. flat spin due to rudder locked while alierons were in nutreal & rudder up, also you had a reward Cg. put all this together and maybe your batt shifts while on a climb & turn disconnects from motor wires

tough call, but I'd say that the plane is tail heavy. Try flying it nose heavy for a while and see if that helps.

My very first RC flight was like this. Got out of the spin maybe 10ft. up ,(Gas trainer high wing modified to low wing.) I had no air speed. She still went in, just softer. It did the same thing nose down , then spin.

Wait a second.. this isn't WWIIOL..

[ballores]

were you wearing video goggles that would have made me puke and spin cheaper than beer

[phidelt08]

Move the CG forward.

Wow. Ive never seen anything like that before. Thats an easystar right? It looks like a standard spin started first (nose down) and then the flat spin developed after it wound up. Did any of your control surfaces lock? A friend of mine got into a spin with a slightly aft cg on a 172 and took him nearly 2000 feet to recover. I would think that if the controls neutralized the aircraft would snap out of the spin right away.
