Trex 700E "The Beast" - Tim Jones insane power

Taken from Helifreak.com. Video and commentary by the godfather of rc helis, Finless Bob :)

Tim Jones has built a Trex 700 electric conversion based around a prototype Castle Creations motor. The initial word was that the motor was putting out around 7 horsepowers.

How ever the last thing I heard about this insane motor (supposedly after some data logging was performed) it was putting out about 10 horsepowers(!). That's over 7000 watts of power output in a machine that weighs just over 5 kilos! Compare that to the stock nitro engine which produces about 3.4 hp (total fly weight here is somewhat lower though).

As an interesting side note (although a somewhat inappropriate comparison) one of the most powerful full scale helis in the world, the American millitary attack helicopter AH-64D Apache Longbow (i.e. the most powerful version) has a power to weight ratio of 0.773 horsepowers per kilo. Even in the wold of rc 3D helis that's powerful. That's how ever without any weapons, fuel or pilot. In the same way the full scale Bell222 (the Airwolf helicopter) has a ratio of 0.598 hp per kilo. Loaded and ready for combat the Apache has a power to weight ratio of 0.499 hp per kilo. Still very powerful.
How ever, assuming this Trex700E conversion heli weighs about the same as other electric conversions "The Beast" should be approaching 2 whole horsepowers per kilo! And that's with the heavy batteries installed.
A Trex 700 is about the length of a 3 seated sofa or couch. It's very big and normally moves like "a hog" compared to smaller sizes but Tim's conversion is like a finch. It's capable of moving around more like a 50 sized heli even though it's a 90 size.

Suffice to say... power to weight ratio on this thing is sick. By far the most powerful rc heli I've ever seen.

Be sure to view in HD and crank up the volume. The blade farts on this thing nicknamed "The Beast" are pure music.

At first I was going to call that fake, but I guess it is not. But I still cannot figure out how the heck you keep that thing in the air. What generates lift when the rotors are vertical to the ground...?

[Utgardaloki76]

The heli isn’t in a perfect 90 degree angle. As you assumed that creates no lift and the heli will fall to the ground and very fast at that. But as long as you tilt it ever so slightly as Tim does in the video and apply the right mix of power and turning speed the heli will stay there. It’s very much like a marble speeding along the inside of a bowl. As long as the speed is enough the marble can’t fall down (while in a perfect cylinder it falls regardless of speed).

It's easier to fly a real full sized jumbo jet without any flying experience than it is to fly an rc plane like the guy in this video. What he is doing is insanely hard without years of experience and expensive crashes.

[98snakeeater]

Yeah, but can it hover?

[dw5386]

Nice recording blob. I dont think it ever left the camera. I was looking up power to weight ratios for cars n stumbled on this lol. This is doot

[kasnitch]

Tim Jones is one hell of a pilot... and then he finishes with no timer on and does a sweet auto in to land... hell ya

[femtophysiker]

Wow... what is that thing! I want it now...

[CamdenWallraff]

...All we need now is to militarize these kinds of helis with pilots like this, and we will be ready to outmaneuver any alien invaders lol. That is a sexy heli.

wooooooooooooooooow!!!!!!!!!!!­

Finished assembling my 700e yesterday and flew it at the local hobby shop in Oakland ME yesterday. The initial rush was amazing as it was blowing advertizing placards off the walls and hats off the heads of the peanut gallery. Very stable and enough power to light up and average size house! And the sound.......

[chopperharly]

Ive been trawling youtube watching helis for quite a while now and this is the most extreme flight i have ever seen, i fly 3d myself but nothing like this wow!!! is all i can say

[ericgoujon]

Ok... Yes...



[azezrtyuuiopqsdfghjk]

Wow, Don't put your head in the rotor, only in halloween aloud.

What for Lipo size/ampere use????
