I have a Trex 700e that I'm contemplating replacing. Main reason is even in a simple crash you're looking at a frame replacement. Not only is it a pain in the a$$ to replace frames but they are not cheap. I'm curious if the Aurora frame design is better at dissipating the crash energy without destroying the packs or frames. Anyone really pile one in yet? How do they hold up?

I'm not sure on durability becuase I don't have one...yet but I have heard a lot of people mention that the parts prices are comparable to the 700 and I would think the quality is much better

It's a complex, costly, glow powered anti-gravity machine!

I have seen one have a real bad crash. There should have been nothing left of it, thats how bad it was. All he needed to replace is the canopy, landing gear, blades, and main shaft.

I didn't locktite the mixing arm well enough on mine and
at about 40' as I was showing my daughters how
solid it flew, the arm came off, blades cut the
tail in half and went down in a huff I couldn't
believe it and I think my oldest daughter has it on
her phone video. It hit VERY hard on the nose and broke
both frames in the front. Other than that, not one arm
or lever, tailbox, almost nothing else was ruined. The
cost of frames just went down at heliproz also. From
$85 to $65. I just missed it I'm rebuilding as I
write. This is one tough heli. I did loose the vertical
and horizontal fins and the support arms and had to replace
all of the torque tube.Two cents worth. The parts quality
of the Aurora and Srimok are the best I've seen.

Is this fun or what :)......

I have had my e-Aurora go in a few times now (due to failed ESC), and it is very durable (at least with the light 4400mAh TP lipos I am using).

But the Aurora is not meant to be a tank. It is meant to be repaired easily. I'm not saying it is flimsy. But when you crash, stuff breaks. However when you crash an Aurora, you can have it flying again in no time because it is very easy (and quick) to repair. The sacrificial tabs for the canopy mounts tend to save the frames, as do the landing gear. The kinetic energy of a crash has to go somewhere.

From a design standpoint, it is my opinion that the Aurora trumps the Trex easily. Besides, it is much better looking. But structurally, the Trex is probably stronger--while at the same time being heavier and more difficult to repair.

There is a circle. Thicker materials require bigger motors which require bigger batteries which require thicker materials--and on and on.

Now there is the guy who is running a 14S Trex 700 with monster horsepower (Beast?). I saw this guy at IRCHA flying. You could hear the heli from a mile away with the blades making a roar sounding like a P-51 Mustang. The Trex 700 can handle this kind of modification where the Aurora cannot. The Aurora is light and spindly and not designed for monster setups. I recommend 4200 to 4400mAh batteries as they are lighter (even though the new frames allow 5000mAh packs to fit easily). A light helicopter is good. It autos gently, and can be thrown around more easily. Besides, the batteries can be charged faster.

Don't buy an e-Aurora thinking you can put one of those 8HP Steve Neu motors in it along with 5500mAh lipos. Plan on a lighter setup.
