Very Funny RC Helicopter Auto Crash, 600 ft Onboard Cam 3D

Very high (approx. 600 ft, 183 m) RC- helicopter flight with movable onboard camera. Very low inverted flying and high speed low pass. Crash caused by failed autorotation!
Vibration problem solved.

Setup: Standard Thunder Tiger Mini Titan E325
BLC-40 (Standard Motor Timing, No Brake, Fast Throttle Response, Standard Discharge Protection, Heli Mode Without Governor
Hacker A20-6XL
Kokam 2100 11,1V 30C H5
3x Thunder Tiger C1016
1x Futaba S3114
1x Hitec HS 55 for camera head movement
Robbe- Futaba GY-240
Align 315 Pro Main Rotor Blades (wooden)- get replaced by Hyperion 325 CFK Blades
Align Tail Rotor Blades for T-Rex 450 (plastic)
Graupner- JR MX-16S, 40 MHz
R16-SCAN
Approx. 2600 rpm at head
Weight 923 g with movable FlyCamOne2

Plastic rotor head gets replaced by an aluminum head

Duration : 0:5:7

thats suck dude but …
thats suck dude but next time you should try to get the plane closer cause i think it lost single and went to far away and never started back up!!! but idk thats my opinion that happend

Hmmm, wooden main …
Hmmm, wooden main rotor blades, one tail rotor blade (replaced both) and one plastic mixing lever.
Costs: 20 Euro (26 USD), it was definitely worth it :-)
Now I am using carbon fiber blades, if they touch the ground it is going to be twice as expensive.
But wooden main rotor blades can also get expensive. Once the heli exploded right in front of me during hovering. Luckily the blades crashed into a wall opposite me. Got the heli second-hand and was checking blade tracking- miles away!!!

nice flying mate …
nice flying mate shame about the crash do you remember what the damage was?

Thanks, the heli is …
Thanks, the heli is fine, got a new ESC and carbon fiber blades. But my new jet is much more interesting right now.
I'm sorry I have to disappoint you, this is no expert flying. Please watch a vid of Alan Szabo, I even can't do this on the flight simulator! ;-)

Hey sorry about the crash. Hope you get it fixed. Best inverted flight i have ever seen. Expert flying i give this video a five star.

The old ESC BLC-40 …
The old ESC BLC-40 caused motor cutouts and stopped working after static thrust tests with my new E-Flite F-15.
But if I would use the Align 325 carbons and lockout the tail rotor I would try it, maybe :-). At scene 04:00 I gave +12° pitch and the heli got faster! Lost the rest of the energy. I only used approx. -5° pitch during autorotation but the decline rate was OK for me. I have read that you have to give -10° pitch for an auto with a 450 heli so the head speed can increase a bit.

At scene 01:53 I …
At scene 01:53 I lost control (unfortunately the camera turned off, happened at my plane vids too). The only thing you can do is to give zero pitch and wait until you can regain control.
If your name isn't Danny or Alan Szabo it is not worth it to try an autorotation landing with a 450 heli :-)
Now I'm using the Hyperion CFK blades and they are even lighter then the Align 325 Pro.
I can't do autorotations on purpose anyways because my new ESC Jazz 40-6-18 has a soft restart everytime.

muni86 @ 1:03 pm

Well I have very …
Well I have very very very good eyes ;-)
Joke, no it is impossible to see the flight position of a micro heli at this altitude (except using binoculars). At 400 ft altitude the heli is only a small dot and you have to stop movement of the dot. But this is only possible if you know the position of the tail, so you need a good head holding gyro. But if you yaw the heli at this altitude on purpose you need much luck that it regains it original position. (Continuation comment below!)

wildwilly87 @ 1:03 pm

dude how do you …
dude how do you still see the heli and fly it when its that high?
ive found those wood blades are really bad for autorotations as they lose momentum really quickly (no weight). The align 325 carbons with the lead weights are great for autos and theyd be nice and stable at 600ft lol (at the exspense of crazy fast roll rates)

ssrc30 @ 1:03 pm

Yes I totally agree …
Yes I totally agree there. I have a T-Rex 600 Nitro and you could cut the head off a bull with that thing if it ever hit one. Love the way it flies but am always looking to buy more heli's. Gotta keep reminding my woman that it's not my fault that the hobby keeps on wanting to expand me:P lol…….. I think a Thunder Tiger is gonna be my next expansion lol

muni86 @ 1:03 pm

I'm really happy …
I'm really happy with the Mini Titan, don't by a Walkera Heli. This is all I can say.
At the beginning the pilot is the weakest part of the system. A bigger heli like the T-Rex 600 is much more easier to fly because of its bigger inertia. But also much more dangerous and expensive.

ssrc30 @ 1:03 pm

Hey thanks for the …
Hey thanks for the info. Are those thunder Tiger heli's really as good as people are telling me? May have to invest in one myself.

muni86 @ 1:03 pm

Thanks for the nice …
Thanks for the nice comment :-)
This is the standard Thunder Tiger Mini Titan E325 canopy. It will not fit to the T-Rex 600 because this heli is approx. twice as big :-o
May be you can take a canopy from the Thunder Tiger 30, 50 or 90, it has the same design.

muni86 @ 1:03 pm

The flying heli …
The flying heli with the camera "only" costs approx. 800 Euro (1150 US-Dollar).
Altogether it costs approx. 1500 Euro (2170 US-Dollar), Flight Simulator, Accus, RC, charger, etc. included.
Buy a heli at this size, rotor diameter approx. 72 cm, so you can only hurt yourself badly, but you can't get beheaded ;-) (may be it's possible to blead to death if the CFK blades hit somebody at the throat)

ssrc30 @ 1:03 pm

Well, we know you …
Well, we know you can fly, and that you can make good videos. What i would like to know is where you got your canopy from? I might try to get one if I can find it for a T-Rex 600.

5/5

I've never done RC …
I've never done RC flying in my life, so I understand nothing about your setup except it sounds like it costs Eight Hundred Million Dollars.

But all this looks awesome. Both the high-altitude camera shots and the inverted flying. It makes me want to try this hobby.

video molto bello, …
video molto bello, più in alto della pala eolica! complimenti!

muni86 @ 1:03 pm

Thanks! You can see …
Thanks! You can see the setup in the video info box.
But the stock ESC BLC-40 gets replaced by a Castle Creations Phoenix 45 because of motor cutouts. So I swap the ESC of the Mini Titan and my new Multiplex Acromaster.

Mate. That was s**t …
Mate. That was s**t hot! The inverted section @2.50 was proof enough you can fly… What rates etc do you use?
