I have been fly the Sabre with plastic blades that releases when they hit my leg. Not is even a bruce. I may be taking things lightly flying the Sabre SE so I am very concern about buying a Trex 450 on how dangerous it can become. What happens if a Trex 450 hit your leg when you are hovering, anybody had that happened to him? What is the difference in terms of safety between the 2 birds? Does the Trex 450 blades release when they hit? I have been flying my Sabre inside my living room and when it accidently hit the dry wall, it just leaves a small black mark without any cuts. I just straighten the blades back and start over. I need your help in accessing the safety level of the Trex 450 before buying it. Is this a bird that I can hover on my drive way? What happens if the blade hit my aluminum garage door or stucco, because my Saber leave it with no marks or damage at all.
If you want a bird that you can hit yourself with and walk away unscathed, then stick with the toys and stay away from the Trex.

If your requirement in purchasing a heli is that it do no damage when the blades strike an object,
Do Not Buy A Trex.
A Trex (as well as any other heli of similar or larger size) has the potential to cause significant harm to any object the blades come into contact with.
It is Not a toy.
As an aside - "safety" is all about the pilot, and has nothing to do with the heli. Kind of like driving a car.

Yourself - Really nasty bruise, eye out, whatever.
Drywall - gash
Garage door - small dent and missing paint
Stucco - Stucco wins I think.
The accepted logic is to avoid flying it into these objects, pets, ponds, trees, grandparents etc.

If you plan on flying a Trex into yourself I hope you have a good doctor, and I wouldn't recommend flying one inside the house.

Think "chainsaw with no handle". Even a little Trex can run a blade-tip speed of almost 200mph. Being hit by a Trex is likely to involve ambulance and hospital.
If you keep this in mind every time you fly it, you will probably be careful enough.
If you really want to fly it inside, make sure no-one is in the room (even you!) because if anything goes wrong schrapnel will fly everywhere.
I got hit in the calf by part of a blade from 20 feet away a fortnight ago (it just toppled over after landing), and it still hurts...

I'm not familiar with the Sabre, but I own an Esky Honey Bee FP. I can tell you from experience that even the plastic blades on the Honey Bee FP can do damage. Case in point...see the photos below. A gust of wind pushed the Honey Bee into my house and the plastic main rotor blades put a hole in the vinyl siding. If the Honey Bee FP can punch a hole in vinyl siding, I would say that human flesh could also be shreaded. :shock: This really woke me up and I now give the Honey Bee FP its due respect. I'm also currently building two 450 sized helis...the Esky Belt CP and Thunder Tiger Mini Titan E325. You can be certain that I will be giving these two helis their due respect, as well.

On the other hand, it's not as dangerous as a car. :dontknow
People treat those without respect all the time.

Safety first, fun second, wife third. :lol: Thanks for the warnings, you have probably save a leg or two, mine or somebody else's. :mrgreen: We have family safety meeting on driving once or twice a year and that probably saved a life or two. :badair:

youre right, but when somebody runs over someone elses kid with a car, nobodys gonna start thinking about banning automobiles. I could see that as a real possibility with this hobby

Spool one up once and you'll get the point real quick that you don't want those blades to make contact with anything let alone soft flesh. It's actually quite funny when new people see the Trex and think it's a toy asking questions and what not. Then they here it spool, and spool, and spool, bystander takes 5 steps back, spool, "holy crap that thing serious!"

My buds T-Rex with glass blades...............
He has an Apple tree in his back yard and was hovering around and hit an apple!!!
Cut that sucker in half and left the other half HANGING on the tree!!!!
Now think about Bruce Lee on Crack with Nun Chucs!!! and you kinda figure it all out!

I have seen a guy hit himself in the back with a trex 450, the very first one with wood blades and it put a HUGE set of gashes on his back. If it would have hit his neck, it would have been bad. He said it hurt like hell and showed everyone the next day and he was pretty purple and bruised.
Why would anyone want to fly into themselves, kinda weird question???

Just take your lawn mower and turn it upside down...........wouldn't want that hitting my leg, or anything else for that matter. :fly
A T-rex 450 is not "safe" in that it can't hurt you whatever you do with it. But it's good you're the sort of person asking the question. Fly sensibly, and you're unlikely to hurt yourself or anyone else.
Get a 2.4gHz radio
Set failsafe throttle to '0'
Don't fly too close to yourself (I'd say 4M min).
Don't overfly other people
Hover at chest height or above head height so if you throw a blade, it's less likely to hit you in the face.
Don't hover with the tail pointing straight at you, in case it throws a blade.
Check everything before you fly.
Probably any helicopter - even the micros - could kill you if you flew it into just the right spot on your neck and severed an artery. Part of me thinks the T-rex is safer in that it's more controllable and so you're less likely to hit yourself with it.

The Helicopter is perfectly safe. What you should worry about is if the pilot is safe or not.
Oh and stay away from poles they heva a tendency to reach out and bat helis out the sky.

this is what happens when just the tail rotor hit you in the face. not because the heli was unsafe, i was un safe.

This is a good example i think of anyone pretending that a RC Heli is a toy.

Quick and simple answer; NO they are NOT safe when in the hands of someone who habitually hits himself or others in the limbs.
Seriously, the right spot and circumstance you could kill someone with the TRex 450, Temple lobe etc, Jugular Vain and carbon blades Eye-balls? Tail rotor is short of a flying router bit at 15000 rpms, there dangerous allright.
Especially in Idle up mode with High RPMS such as 2200 or so, I got knee slapped with about 600 rpms on a spool down accident and hurt like hell, broke skin and bled. Through my BlueJeans.:oops:
